There are obviously costs involved in setting up residential solar panels. Today, we’re going to look at these and balance them up with the financial gains you’ll experience. It’s a busy day, so let’s get right in:

Cost #1: Equipment.

Equipment forms the largest part of the entire solar power setup. These are PV panels, inverters, battery bank, regulators, et cetera. Equipment cost can be spread out over time if you want to expand your solar power generator over time. Perhaps your goal is to be able to build up one more solar panel every weekend. Thus your cost really spreads out over time. It can really be less taxing on your wallet this way.

Cost #2: Installation

If you want to do the installation yourself, you won’t have to worry about this cost. But if you want to get a professional or contractor to do it for you, remember o budget for this as well.

Cost #3: Interest

If you took up a loan to pay for your PV panels and other photovoltaic components, the interest is going to build up and this must be factored into the overall cost as well.

Cost #4: Permits, Fees and Taxes

In some locations, you’ll need to pay for permits and fees when you install solar panels over your roof or on your property. Generally, most states let you install solar panels without imposing taxes on them. But be sure to check with your local authorities so you know if you need to pay for any taxes.

Cost #5: Clearing Refuse

If you need someone to clear out any refuse for you, you may need to pay for their service.

Now these are all costs…how about the benefits, I hear you ask. Well, here are the financial gains you’ll enjoy:

Benefit #1: Lower Energy Bills

The most obvious benefit is the reduced (or eliminated) electricity bills. If you are adding solar panels gradually to your collection of “solar harvesters”, your energy bills will gradually reduce and may finally be eliminated.

Benefit #2: Hedge Against The Rising Cost of Energy

The cost of energy is set to rise as inflation and scarcity forces its price upward over the long term. We all experience this effect — everything seems to get more expensive! Yet when you’re tapping energy from the sun, it doesn’t get more expensive then when you first bought the photovoltaic equipment. Therefore while the rest of the world pays for electricity through their nose, you can quietly enjoy cheap electricity using solar panels.

Benefit #3: Appreciation

The price of your property will probably appreciate because you installed an asset. Depending on the valuation, you may get back what you paid for. This mean you’re really using all the energy for free through the years. If you built your own residential solar panels, you’re definitely going to get back more than you invested in equipment and other photovoltaic components.

Let’s take a look at Synchronous Solar Panel Inverters…

2. Synchronous Solar Panel Inverters

Synchronous solar panel inverters are also called Grid-Tie Inverters. If you want to have a grid-tied solar power generator, a synchronous solar power inverter will suit you well.

This type of inverter takes the electricity generated by your solar generator and feeds it to the distribution panel in your home. The power is either used by the appliances at home or flows out to the utility grid. If you generate excess power, you are able to sell the energy to your utility company at the rate you’re charged.

When there is no solar energy available during cloudy days (and at night), the system seamlessly taps into the grid supply to make up the difference in power.

As such, you are able to use energy from the grid or from the photovoltaic panels. With this design, you will not need to worry about an increase in energy consumption. In case the solar panel system you design is a little too small, you can use the grid power to supplement your consumption.

Next, let’s go see what a Multifunction Solar Panel Inverter can do for us…

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!

After you know where most of your household energy goes to, you are now ready to plan for your system size. For grid-tied system (without batteries and charge controllers), you only need to make sure the inverter you use is large enough to handle the power generated by the solar panels.

If you are thinking of scaling up your system in the future, you can get a bigger inverter so there’s room to handle more power. You can also get an inverter that fits the power output of your current solar panel, and then add another inverter when you bring in more solar panels. Between these two options, it’ll be more cost effective to have a larger specification if you know your plans beforehand.

For solar power generators with batteries, you’ll need a little more planning…

For a start, we’ll look at how to determine the size of your solar array. Here are the steps to do it:

1. Compute the average Watt-Hours (usage) per day

2. Find out the Average Daily Solar Radiation figure for your location

3. Calculate the number of watts you have to generate per hour of solar exposure (divide #1 by #2)

4. With the solar module you have in mind, multiply its power rating by a factor of 0.7. If you are using a Maximum Power Point Tracking (MPPT) charge controller, you’ll multiply it by a factor of 0.8 instead.

5. Finally, you get the number of modules needed when you divide #3 (energy you need) by #4 (energy generated by your solar panels)

After you arrive at the number of solar modules you need, you’ll also know how much space is needed on your roof. If there isn’t enough space, choose a more efficient photovoltaic module and do the calculations again. Going over this a few times, you will be able to find the solar module that’s most suitable for you and at the right price.

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.”

Are you ready for what Multifunction Solar Panel Inverters can do for you? Let’s jump right in…

Multifunction solar panel inverters combine the best from Stand-Alone Solar Panel Inverters and Synchronous Solar Panel Inverters. They are of course more expensive, but these are the best choice for your solar energy panels.

This type of inverter allows you to generate excess power to be stored in a battery bank. As such, you are able to use energy from the grid, from the solar panels or from stored energy in the batteries. You can even connect a standby generator to the whole setup. Let me illustrate…

During the day, solar energy panels supply your household appliances with power. At the same time, the battery bank is charged up to store energy for the night. If there is surplus electricity, they can be sold to your local power company.

By evening, the batteries will be charged up. At this time, the inverter provides AC power to the house from the batteries. If the batteries are flat, the inverter taps into the grid to charge the batteries and power up the house at the same time.

If a standby generator is used, the inverter will synchronize its power so it can be added to an existing source of power. Many multifunction solar panel inverters are not as efficient as synchronous inverters because the system must have a battery. However, they offer functions that grid-tied inverters do not.
