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.

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!

This is the third and final part of the “Sizing Your Solar Energy Panels” series. Have you done some calculations for your future solar power system yet? If you have been doing those mini exercises, you’ll most likely find a suitable solar panel for your home by now.

The next step requires us to find an appropriate-sized battery bank, inverter and charge controller. Let’s look at each of these:

1. The Inverter

The inverter you choose has to be sized according to the demands of the alternating current (AC) side of the circuit. Therefore you will choose a specification according to the loads in your house (with a little buffer in case you increase your loads over time). Pretty straightforward.

2. The Charge Controller

You’ll at least need a basic charge controller to begin with. Until you get fussy about how advanced you want this component to be, more affordable models will do just fine. You’ll need to get a specification that fits the output current (Amps) of your solar panel arrays. If you intend to scale up your solar power generator, you’ll do better with a larger charge controller with room to accommodate more solar panels than with two smaller-sized ones.

3. The Battery Bank

The size of your battery bank depends on how you want to use your solar panels. You can size your battery banks such that it can get you through thick clouds that pass by, or you can size them so you can get through three solid days of solar eclipse and a power outage at the same time. It really depends on you. But take note that over-sizing isn’t always realistic. You have to take into consideration the space they occupy and the how much they’ll cost you.

If your home is grid-tied, provided there aren’t frequent power outages, the size of your battery bank isn’t critical. Just size it to take care of cloudy days will do. You can still maintain your lifestyle by drawing power from the grid.

When you design your battery bank, you’ll have less power loss (through wires) if the voltage is higher. If you are able to design a 48-volt system, you can conserve more power than when you use a 24-volt or 12-volt system.

In order to size your solar energy panels, you have to decide if you want a direct grid-tie system without batteries or not. If you do not want to use batteries, the size of your solar power generator will simply be what you can comfortably afford ($$). This will help you offset your energy bills, but you’ll have to draw power from the grid at night. Things will be rather different if you want to install an off-grid system with a battery bank.

Contrary to what most people think, step #1 to sizing your solar power system is to check if there is any energy wastage in your home — lights that remain turned on 24/7, pool pumps that keep running even during the night, heaters that never stop pumping hot air, et cetera. Only after you have eliminated these “leaks” can you determine how much energy (KWh) you use every day. Otherwise you’ll be spending lots of money on a larger-than-necessary solar power generator.

It’s easy to determine how much power you use on a daily basis. A quick glance at your utility bill quickly reveals the number. This is the result of those big power-sucking elements around the house. Some examples are your clothes dryer, water heater, air conditioning, refrigerators and heaters. Having your power consumption in mind, you’ll have to multiply it by a factor of 1.15 to correct for power loss through inefficiencies in the system. (Inefficiencies occur as a result of imperfect transmission through the inverter, cables and batteries.)

Even if you are not going to immediately build a solar energy panel now, it’ll be useful to go around your house to look for these energy vampires to slay. Before we go on to the next part of “Sizing Your Solar Energy Panels” series, please do this exercise. It’ll be beneficial to you in the long run and you’ll thank me for it.

The article below shows how practical solar panels are in a disaster scene. Currently Haiti is facing one of the most severe natural calamity in recent history. In such a time as this, electricity is most needed. However most of the electricity supply is cut off and there isn’t enough mobile generators at the scene.

People are screaming for help while thousands are waiting for more medication. People who desperately need surgery are not receiving it because electricity is needed to power the equipment.

Thankfully Sol, Inc. has chipped in their effort with photovoltaic panels. Hooray! This is what Rick Schuett, CEO of Sol, Inc. said:

“We know that once our solar lighting systems are installed, we will effectively double the amount of available relief effort time by allowing aid workers and rescuers to work around the clock when previously operations had to cease at dusk. In addition, our lighting systems will provide safety and security as well as being a hallmark that civility is being restored to the area.”

If you’ve ever built DIY solar panels of a considerable size, you’ll probably come across this important component — the charge controller. The role of a charge controller is to regulate the charging voltage on the batteries.

When sunlight gets brighter, solar cells produce more voltage. Excessive voltage may cause over-charging which may damage your batteries. You’ll need this component if you want to store excess electricity from your solar energy panels.

Many modern charge controller units have a 3-stage cycle:

1. Bulk Phase – During this phase, the charging voltage gradually rises to approximately 14.4 to 14.6 volts (to charge a 12V battery). It is at this stage when charging current is maximum.

2. Absorption Phase – Voltage is maintained at the bulk level for a specified time. As the battery is charged up, current tapers off gradually.

3. Float Phase – After the absorption phase, voltage is lowered to about 13.4 to 13.7 volts (float voltage) and batteries draw a very small, maintenance current until it goes through the discharge cycle.

There are several different types of charge controller to choose from — some with fanciful LCD displays and others with battery temperature monitor. If you are building your first solar power generator, it may be more practical to buy basic ones to begin with. After you’re more acquainted with these components, you’ll have more knowledge to get the most out of more advanced charge controllers. Most multi-stage, Pulse Width Modulation (PWM) types of charge controllers will do great, really.

Many appliances for RVs, boats and camping use 12VDC supply. When you are outdoors having fun, these appliances provide you with all the convenience and comfort. Here’s a list of such 12VDC appliances:

• Hair Dryer
• Heated Travel Cup
• Heavy Duty Metal Fan
• Wet Dry Vacuum with Gallon Canister
• “All Season” Heater/Fan with Swivel Base
• Crock Pot Slow Cooker
• Flexible Map Light
• Frying Pan
• Heated Fleece Blanket
• Portable Stove
• Rechargeable Flashlight with Adjustable Head
• SnackMaster Deluxe 12-Volt Family-Size Cooler/Warmer
• Digital/Electric Compass with Ice Alert
• et cetera…

I’m sure you’re familiar with these…

However there are times when the accumulators run empty just when you need to draw power from them. Thus a 12VDC solar panel will be ideal to ensure these appliances work at all times. With such nifty devices, these inconvenient moments will only be  memories.

During the day, solar panels will bring the accumulators to full charge. At night, power is drawn exclusively from the batteries. If you’re running some appliances only during the day, you may not need batteries… you can plug straight into the solar panels to power these appliances.

Many appliances do not really care if the power is clean, so you can also power most systems that require 120VAC using an inverter. Although you loose efficiency, it may be worth a try.

Let’s take a look at an example of what you can use for a 12VDC solar panel:

And this is how an inverter with 12VDC input will look like:

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.”

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.
