It takes a little skill and practice to harvest components from pre-owned or broken solar panels. Yet it is not so difficult that you cannot manage it with basic DIY skills.

You have to free the photovoltaic cells from the base it’s mounted on. After you have done this, check the solar cells for loose connections, broken panels, condensation and damaged diodes. Common problems such as these can potentially cause your solar panels to break down shortly after installation.

If the joints between solar cells are broken or loose, you have to re-solder them. Malfunctioned diodes can be replaced with new ones from your local component store. And if you see broken photovoltaic cells, you will have to source for a similar component to replace it — this can be challenging. Yet you can still make do with the broken cell in case your efforts to replace the broken solar cell fail. There will be reduced power output as a result, but this is not a grave concern.

The array of solar cells is usually mounted on a piece of masonite or acrylic (substrate) board before it is placed into a new solar panel frame. You can discard this substrate after a few years if you intend to replace the solar cells with fresh, new ones.

Using pre-owned solar panels to build DIY solar panels has its pros and cons. The most obvious advantage is the price. Used solar panels can be very cheap and some kind contractors may even give them to you without asking for a single cent. You are also less worried about breaking expensive photovoltaic panels while building your project.

On the other hand, a used solar panel’s lifespan may be significantly shorter. Their power output will also be a little lower compared to when it was new. A loose connection or a fault may hide itself somewhere that escapes your attention. As you build your DIY solar panel, trouble may spring up from these areas. However this can be managed if you’re careful in checking for potential failures.

Overall, harvesting parts from a used solar panels proof to be the best money saving method to build DIY solar panels. The only downside is the additional effort you have to put in. Yet as DIY hobbyists, we tend to take joy in such labor.

Electric golf carts use 24 volt, 36 volt or 48 volt systems. Most of them have 6 batteries. Thus if the batteries are rated at 6 volts, yours is a 36-volt system. Similarly, if the batteries are rated at 8 volts, you have a 48-volt system.

Every golf cart can make use of solar power to charge its batteries. There are solar panels in the market that can supply between 190 to 380 Watts per solar panel with an output of up to 88 volts. Therefore solar panel technology nowadays is more than sufficient to power golf carts.

When batteries are constantly recharged while out in the sun, their lifespan can be extended by up to 30%. This can also increase a golf cart’s driving distance by up to 12 miles every day. This helps you reduce the maintenance cost of your golf cart. On top of this, when you use solar energy, you reduce your electricity bills.

Solar panels are eco-friendly and have zero carbon emissions while operating. Moreover they are easy to install and are even easier to maintain. All branded solar panels come with at least 10 years of warranty so you will not need to worry about defects.

And if you are not willing to pay the solar panel cost upfront, some manufacturers even have a customized leasing program for you to take advantage of.

Most contractors will be happy to convert your golf cart for you at a small price, included in the package. You can also do this yourself if you want.

All you have to do is to first understand how your golf cart batteries are charged.

Some golf carts have their own in-built battery charger. You only need to supply it with 110 VAC to charge the batteries. Others require an external battery charger.

If your golf cart takes in 110 VAC, you can either use a DC-to-AC converter or get a charge controller and wire it directly to the batteries.

After understanding how your golf cart batteries are charged, you can proceed to mount the solar panels on the golf cart’s roof. Do note that solar panels are heavy and you may need to change (or reinforce) the supports to the roof.

Once the solar panel(s) are secured, take a little drive. If your roof sways from side to side, you may need more support.

Most likely, you will need to fit a charge controller to your golf cart. Find a compact model that can fit into an empty space inside your golf cart. This location must be shielded from water and rain so your batteries do not get short-circuited.

After securing the charge controller, the final step is to connect the charging cables to their respective terminals and secure them properly.

Within a few hours, you’ll be using solar power to charge your golf cart batteries.

Solar Trickle Chargers are small, low-current solar panels used for maintaining storage batteries for your vehicle or boat. Why will you need to maintain them?

All batteries lose charge over a period of time because of self-discharge. By using a trickle-charger, you can replace those lost power. This helps to extend the lifespan of your batteries and ensures you have a smooth start every time you turn the ignition. There is no fear your vehicle or boat won’t move after storing away for a long time.

Since we only need a small current to maintain the batteries, solar panels will be the ideal candidate. As long as there is sunshine, you can be sure your batteries can be maintained in top condition.

But not all solar panels can be used for this purpose. You have to make sure the trickle is large enough for your battery size.

First, you’ll need to find out how big your batteries are. This information is usually written at the side of the battery. If no information is available, try looking up the model on the Internet. Most of the time you’ll find what you want.

If your battery is rated at 100Ah and you estimate that it’ll lose 30% of its power every month, you can work out the power loss per day. (This is about 1% every day.)

Next, find out the sun hours you receive at your location. With this figure, you can divide the energy loss per day by the sun hours per day to determine how much current your solar energy panels need to generate.

If you’re lost, solar trickle chargers will usually have specifications that show you what battery size its suitable for. Have fun!

Home Valuation Increases When Solar Panels Are Installed

The payback for your solar panel investment doesn’t stop at monthly utility savings. When you have a solar generator on your roof, property valuators will take that into consideration.

The increase in your home valuation depends on the reliability of your solar panel system and its remaining lifespan.

Think of your solar panels and solar heaters as equipment that provides value (in this case savings) to the buyer.

If its (projected) remaining lifespan is longer and the brand gives people confidence in its reliability, buyers will be willing to pay more for this asset.

Suppose you decide to sell your home five years after installing PV panels (or a solar water heater) and your system saves you $50 per month on utility bills.

Prospective buyers for your house are willing to pay more for your home because you can help them save $600 every year on energy bills. On top of that, they don’t have to get a separate loan for the solar installation.

Some valuators feel that by having solar panels on your property, your home’s valuation improves by 125% of the solar installation cost. Thus investing in solar energy generators allows you to list your home at a higher price. You may also get it sold faster. This is especially true when oil price shoots toward the sky.

Between solar water heaters and PV panels, solar heaters will give you a better return on investment and also a shorter payback period.

This is because solar heaters are relatively cheaper, are much more effective and helps to reduce heating costs in significant ways.

Thus if you haven’t installed anything yet, consider this route. Use solar water heater to heat up your swimming pool, hot tub, shower room, living spaces, et cetera…whatever you can think of. There are numerous techniques to get heat flowing where you want it.

After you have experienced the benefits of solar heating, then move on to photovoltaic panels. After all, more than 44% of our utility bill is attributed to heating cost.

With the combination of solar heater and photovoltaic panels, you have a good chance of moving towards self-sufficiency. After the payback period, your utility bills will no longer be a pain, because it’ll be free.

Calculate Your Payback Period

The payback for your solar panel investment is the amount of time needed (in years) for your investment to pay for itself (break-even).

A simple calculation gives you a clear picture:

You should divide the total upfront cost by your monthly estimated savings. This gives you the payback period in months.

Dividing this by 12 gives you the payback period in years.

To figure out your monthly savings, you can follow these steps:

1. Determine your average monthly energy usage by referring to your power bills

2. Estimate how much energy (in percentage) you will replace with your solar panels

3. You’ll find out your monthly savings by multiplying the numbers you got from step 1 and step 2 above

For example, you found out that your monthly energy bills cost you $200. If your solar panels are designed to supply about 60% of your energy usage, your monthly savings will be: $200 x 60% = $120

Thus if your solar equipment and installation cost you $14,000, your payback period is $14,000 / $120 / 12 = 9.7 years.

For all the gains you’ll receive from your investment, you have to take a look at what your risks are.

I’ve listed the major ones here so you can consider if owning solar panels are indeed worthwhile:

Risk #1: Efficiency declines over time

Solar energy systems (like everything else) decline in efficiency over time. After a period of 10 years, you can expect a 15% drop in efficiency.

Different systems deteriorate at different rates though. The expected efficiency deterioration is subtly implied in the manufacturer’s warranty condition.

Risk #2: Lifespan of solar panels

Everything has its lifespan. For solar panels, warranties usually cover your equipment for 20 to 25 years. You system is insured against defects and drastic drop in performance during this period. However solar panels can last much longer, sometimes beyond 30 years.

There will come a time (that is not definite) when your PV panels cannot generate the amount of electricity you require and it’s ready to be discarded.

Risk #3: More efficient technologies

Some years in the future, technology will improve. Occasionally engineers discover breakthroughs that make solar panels efficiency improve by leaps and bounds. In this case, unless you have lots of cash to throw away, you are bound to the old photovoltaic technology.

In Part 3 of this series, we’ll take a look at how solar panels can improve your property’s value. This helps in the payback period, definitely.

Reduce Carbon Footprint

Using residential solar panels help your household reduce carbon footprint. As you already know, solar has no carbon footprint. Solar energy is also renewable and sustainable.

The only possible carbon footprint that solar panels have is when they are being produced at the production line. However this is very small compared to the electricity they generate over their lifespan.

Most energy sources are burnt to generate electricity. Each resource produces different amounts of carbon under combustion. The worst of these is coal. They are known to harm the environment in many ways. Unfortunately the United States depends on coal to produce more than half of its electricity.

It is estimated that the average annual carbon dioxide emissions per person in the United States is 20 metric tons. Compared to the world average of four tons, we are really consuming lots of energy even though we do not know it.

At home, we are also using more energy than we realize. This is due to transmission line inefficiencies. Long lengths of transmission cable encourage electrical resistance. Thus the power station has to generate more energy than what we need.

By the time electricity reach our houses, a part of it has already been lost through Joule heating (this is also known as Ohmic heating or resistive heating). Therefore if we consume only 3kWh of energy, the power station may have to generate 9kWh in order to compensate for the loss.

We can all do our part to reduce our carbon footprint by using solar power. It is a misconception that we need to raise at least fifteen thousand dollars before we are able to use solar energy. It is true that it takes quite a bit of money to install photovoltaic panels on our roofs. But we can all start with solar heaters, which are relatively inexpensive.

Solar heaters use solar energy instead of electricity to heat up water or air. Thus it leaves no carbon footprint.

If you want to use PV panels, you can install a few pieces first. This lowers your initial outlay. Then when you have the cash (or have your loan approved), you can buy the rest of the PV panels to generate more electricity.

In fact, on a clear sunny day, 1 kWh per square meter of solar energy falls on the Earth. Most commercial silicon solar cells only have an average of 15 percent efficiency. Thus most of these energy is yet to be harvested using today’s technology. But there is a lot of potential in solar technology.

With better engineering, residential solar panels may double its efficiency, making them more affordable. This will help many homeowners use solar energy on a daily basis. As a result, there is a chance we can permanently reduce our carbon footprint.

Different manufacturers produce varying solar panels quality. While better quality panels command higher price tags, they tend to last much longer. This additional lifespan often justify the added expense. However many people will rather save money by choosing lower quality solar panels than cough out the difference for higher quality ones. This is understandable.

As solar panels produce electricity under the effect of sunshine, they begin the irreversible process of aging. When they age, their resale value decreases. Thus it is important to verify with your sales representative the age of solar panels you are receiving. Stored solar panels, on the other hand, maintain their full lifespan. Thus solar panels do not lose their value while kept on shelves unless a new technology renders them obsolete. By then manufacturers will have to slash their price to move them out of the storehouse.

Despite their image, used solar panels aren’t all that bad when it comes to payback period. Although they have a shorter lifespan and a slightly lower efficiency, most of them are still in good working condition and can last many more years. Best of all, they’re cheap. Therefore you should keep your mind open — as long as the price per watt and warranty conditions justify the purchase, you should be on your way to purchase cheaper energy.

As technology improves, the cost (per watt) of solar panels decreases. Currently, consumers often get solar panels below $5 per watt. Understandably, prices vary from location to location. Therefore you have to contact a few solar panel manufacturers to understand how they price their products before you sign on the dotted line.

If you want to install a solar panel system that can supply your entire house with power, it is not surprising to find manufacturers quoting you a whooping $25,000 to $30,000 for the entire installation. This may appear to be expensive. But the system can serve you for more than two decades and they usually pay for themselves slightly after the first. Therefore you’ll be able to live on free electricity for another ten years after the payback period.

Certainly, a manufacturer’s quotation depends on how big your house is and your average electricity consumption. If you’re able to find and eliminate energy wastages around the house, you may reduce to a smaller system. This means you end up paying less. In every household, there are wastages that account for a huge portion of energy consumption.

An alternative to commercial, off-the-shelf system is the DIY solar panel. Those of us who are apt at working with simple tools and electrical circuits can make for ourselves a homemade solar power system. Do not be mistaken…these are not some shoddy projects that over-the-edge enthusiasts make. The solar cells and related components are from renowned manufacturers. The DIYer’s only involvement is putting various components together to make a solar panel, and then install this solar panel on their roofs. These can last as long as commercial panels at a fraction of the cost.

Whatever your choice may be, understanding the cost of solar panels involve a little fact find. Hopefully, if you compare between suppliers, you may be able to find a solar power system that suit your budget and energy needs.

Why do people want to buy a used solar panel? The answer is obvious. Consumers choose to use solar energy for two main reasons – to cut down on energy bills and to preserve the environment. Therefore they want to spend the least money on the panel that gives them the most power output. The best candidates for this criteria are pre-owned photovoltaic panels. It is also environmentally friendly to reuse (or recycle) photovoltaic panels as much as possible.

Pre-owned solar power generators maintain up to 90% of their efficiency as when they were new. This is true even though the panels may be more than 10 years old. This often means you’ll get more wattage output for a lower price tag.

The only disadvantage is that new panels have better aesthetics, are lighter and take up less space. This is due to improved product design and better materials used. Also, the lifespan of used solar panels will obviously not be as long as brand new ones.

Pre-owned panels can be bought on eBay or from an agent. The source of these panels comes mainly from corporations that want to replace their panels with newer, more efficient ones. Others come from residential buildings. Whatever the source is, you’ll have to perform simple checks to make sure you’re not buying a lemon.

Most importantly, you need to be convinced that the used panel you buy is worth the price you pay for. Having this in mind, the cost per watt (for a used panel) has to be at least 20 to 30 per cent cheaper than brand new panels. Otherwise you’ve paid too much. This is a helpful guideline that can help you differentiate between the good buys and the bad ones.

You’ll also need to visually inspect them to see if there are any loose connections or rusted parts that need to be replaced. Remember to check the bypass diode as they are frequently burnt. This is often the reason photovoltaic panels are discarded. Simple faults like this can be immediately rectified with new components and a simple soldering iron.

While shopping, you may also have observed that some used solar cells have turned brown. This is because older cells contain a plastic substrate that becomes tinted after years of exposure to sunlight. However, electricity output is in no way reduced because of this.

If you want to buy used solar panels, the tips above can help you save a lot of money by buying the right panel that can serve you for years.

Solar energy panels can be used in the smallest ways to improve our lives. There will always be those inconvenient problems that can be solved by using a solar panel in a creative way.

Do you have a boat, recreational vehicle (RV) or truck that you do not use often? If you have problems starting them from time to time, a solar charger is a cheap and effective solution.

With about $30, you can get a small solar charger to plug into your vehicle’s cigarette lighter jack. As you lay the photovoltaic panel on your dashboard, it trickle charges your battery. When you need to start your vehicle (or boat) the next time, it won’t fail you.

The beauty about solar chargers is they won’t overcharge your batteries. Therefore you won’t need extra components like a charge controller that adds to its cost. You can even let the solar charger remain plugged in while you’re driving. As a bonus, solar chargers tend to extend the lifespan of your battery by about 50%. So for a mere $30, you can squeeze $50 out of an accumulator that costs you $100. How’s that for good investment?

More than just dollars and cents, the peace of mind you have every time you need to start your old truck or seldom-used boat is worth its weight in gold!

Here’s an example of what I’m talking about…the Sunforce 1.8-Watt Solar Battery Maintainer:

“Sunforce 1.8-Watt Solar Battery Maintainer Twin Pack is comprised of two solar battery maintainers ideal for cars, SUVs, boats, ATVs and PWC batteries. The units are completely maintenance free and easy to install. The amorphous solar panels charge in all weather conditions, even on cloudy days. The panels plugs directly into your cigarette lighter. Complete kit for each unit includes 1.8-watt solar battery maintainer, 7.5 feet wire, 12V DC plug, suction cups for easy mounting and battery clamps. Temperature range from -40 to 176 degrees F.”

Some batteries require maintenance. If they are not cared for, their chemical properties can be affected. This leads to premature failure. Other batteries do not require maintenance, but may not be suitable for solar applications. Before buying batteries, you have to consider each model’s characteristics and see if it fits your intended use.

Let’s consider 3 types of rechargeable batteries we commonly see in the market: Lead-Acid batteries, Alkaline Batteries and Sealed Gel-Cell Batteries.

There are pros and cons to each type of battery, so let’s look deeper.

Flooded Lead-Acid Battery

This type of battery was used since homeowners began to install solar panels on their roofs. They have the longest proven track record. (Thus you can consider them to be pretty reliable.)

In fact, most off-grid solar power systems use this type of battery. This is because they have the longest lifespan and are the cheapest among different types of batteries (in terms of cost per amp-hour).

However these batteries require regular maintenance. You have to water it regularly, equalize the charge and clean the terminals frequently.

Flooded lead-acid batteries commonly used for photovoltaic systems include 6V golf cart batteries, 6V L-16 batteries and 2V industrial cells.

Absorbed Glass Mat Sealed Lead Acid Battery (AGM)

Sealed lead acid batteries gained popularity as their price came down. Unlike flooded lead-acid batteries, they do not require as much maintenance. They are ideal for grid-tied PV systems that use rechargeable batteries as backup.

AGMs are completely sealed. Therefore there is no danger of spilling and they do not need frequent watering or charge equalizing. It is designed such that no corrosive fumes are emitted. Its electrolyte also does not stratify.

During storage (or transportation), an AGM’s self-discharge rate is less than 2%. Thus they are popular with any setups that do not require frequent battery use.

AGMs are highly resistant to any forms of vibration, thus they are ideally suited for mobile solar power systems installed on vehicles and boats.

These batteries used to be very expensive. As such, they were only installed on commercial systems where maintenance was impractical or near impossible.

Today, AGMs are only slightly more expensive than other battery types. Thus many homeowners are willing to sacrifice some money for the sake of convenience.

Gelled Electrolyte Sealed Lead Acid

Gelled lead acid batteries are quite similar to AGMs in terms of its advantages. There is one important distinction, though. Gelled electrolyte is very viscous. Therefore recombination of gases generated while charging takes place at a very slow pace.

This means you can only charge them slowly…much slower than AGMs and flooded lead acid cells. If they are charged quickly, gas bubbles form on the metal plates. This reduces electrolyte contact. As a result, the battery’s capacity is temporarily limited until the bubbles find its way to the top of the electrolyte.

For off-grid solar power systems, this characteristic is not helpful. During the day when solar panels generate electricity, you have to store as much power as possible. If the charging rate is low, a lot of power is wasted. Therefore such batteries are more suited for grid-tied systems where the majority of electrical current is channeled back to the grid.

Deep Cycle or Shallow Cycle?

The battery is an important component of your solar power system. Thus its performance and longevity is of utmost importance.

For solar applications deep cycle batteries are used. Compared to shallow cycle batteries, deep cycle batteries can be repeatedly discharged to 80% of its depth of discharge (DOD) and can be recharged from this state without damage.

Commonly batteries used in automotives and lighting belongs to the shallow cycle type. These are not suitable for a PV system. The lead plates in these batteries are thin and have a large surface area. Even though it can provide a high current in a short time, these batteries cannot be discharged deeply without damage. At least deep discharge cycles can shorten their lifespan quickly.

Deep cycle batteries have thicker lead plates and less surface area in contact with the electrolyte. As such, these batteries produce less current than a shallow cycle battery. However deep cycle batteries can sustain its current over a long period of time (unlike shallow cycle batteries), which is ideal for solar power applications.

Deep cycling puts a toll on your battery’s lifespan. This applies to deep cycle batteries too. Therefore if you want batteries to last longer, use deep cycle batteries and shallow cycle them (as much as possible).

Storing Your Batteries

Place your battery bank indoor where it is warm. Batteries work best when they are about 25 degree Celsius. If batteries are cold, chemical reactions slow down. Therefore less current flows out of the batteries. You may have experienced trouble starting your car in cold weather. But when the battery warms up, its performance improves dramatically.

On the other hand, batteries cannot be exposed to high temperatures too. At 43 degree Celsius, rechargeable batteries can be damaged and their lifespan shortened drastically.

When buying batteries, you must remember there is no perfect system. Energy is lost to heat (or other forms) as it flows from one component to another. When electricity flows into your batteries, some of it is lost.

Therefore you have to factor this into your decision and get more batteries to compensate for power loss. As a rule of thumb, you should have 10 to 15% more power storage (batteries) than what you need.

Maintenance

Batteries need maintenance. Make sure you keep the electrolyte at full level, as much as possible. If not, you must at least keep it above the minimum level. Otherwise the plates may get exposed to air. When refilling, use distilled water.

Water is lost as gassing occurs. This is a process of splitting water molecules into hydrogen and oxygen. It occurs during charging when the chemical reaction cannot keep up with the energy input.

In flooded lead acid cells, some gassing is useful. It introduce movements in the electrolyte and prevents stratification. Denser acid tends to stay at the bottom and they are stirred as gassing occurs.

As a result of gassing, an acid mist is formed and this is highly corrosive. Therefore you have to check the metallic connectors for signs of corrosion or damage from time to time. Clean the top of your batteries regularly with baking soda and water. Baking soda, being alkaline, will neutralize the acid on the battery and connector surface.

Other than refilling and wiping your batteries, you must also equalize them every 2 to 3 months. (This should be done in a well-ventilated place.) During this process, increased gassing occurs and this cause the water level to drop.

To equalize your battery, simply overcharge it under a controlled voltage for a period of time. While doing so, your battery must be closely monitored. You must keep measuring the specific gravity values of the electrolyte. It increases as you equalize the battery. When there is no change in specific gravity reading for 30 minutes, the equalization process is completed.

Used Or New?

When buying batteries, it is tempting to spend less money by purchasing pre-owned stock. This is understandable. After all batteries are not cheap. And expensive batteries don’t mean they are good or suitable.

The issue with used batteries is you won’t immediately know how they were used and maintained. If you send them for load testing, you can find out their remaining lifespan. Otherwise they can turn out to be the most expensive batteries in the market.

When you find out facts and use simple logic to your decision making process, you will find batteries that can last for ages without failing.
