F.A.Q'S

How do solar generate electric?

(Photovoltaic or PV for short can be thought of as a direct current (DC) generator powered by the sun. When light photons of sufficient energy strike a solar cell, they knock electrons free in the silicon crystal structure forcing them through an external circuit (battery or direct DC load), and then returning them to the other side of the solar cell to start the process all over again.

The voltage output from a single crystalline solar cell is about O.SV with an amperage output that is directly proportional to cell's surface area (approximately 7A for a 6 inch square multi-crystalline solar cell). Typically 30-36 cells are wired in series (+ to-) in each solar module. This produces a solar module with a 12V nominal output (-17V at peak power) that can then be wired in series and/or parallel with other solar modules to form a complete solar array to charge a 12, 24 or 48 volt battery bank.)

Will solar work in my location?

(Solar is universal and will work virtually anywhere, however some locations are better than others. Irradiance is a measure of the sun's power available at the surface of the earth and it averages about 1000 watts per square meter. With typical crystalline solar cell efficiencies

Around 14-16%, that means we can expect to generate about 140-160W per square meter of solar cells placed in full sun. Insolation is a measure of the available energy from the sun and is expressed in terms of "full sun hours" (i.e. 4 full sun hours= 4 hours of sunlight at an irradiance level of 1000 watts per square meter). Obviously different parts of the world receive more sunlight from others, so they will have more "full sun hours" per day. The solar insolation zone map will give you a general idea of the "full sun hours per day" for your location.

How much will a svstem cost tor mv 2000 square foot home?

(Unfortunately there is no per square foot "average" since the cost of a system actually depends on your daily energy usage and how many full sun hours you receive per day in your area; and if you have other sources of electricity. To accurately size a system to meet your needs, we need to know how much energy you use, and the average peak sun hours in your area. The cost of the system will depend on the percentage of electricity you hope to gain for your energy needs.)

What is the cost?

(The cost varies, but you can estimate it with relative ease; all you need to know is what equipment you need and the labor cost. We've gone over the basic parts you'll need for your solar power array: the solar panels, a GFCI, a solar array breaker, an inverter and battery bank. If you don't want to fuss with purchasing each of these components individually you might be interested in purchasing an off-grid solar kit.)

Which type of system is right for me?

(The type of system you might want for your home or business depends on a number of variables, including geographic location, the amount of energy you need to produce, and the size of the investment you plan on making.)

But where do i begin?

Getting started might seem like a daunting task, but it's not as complicated as it first seems. With only an electrical bill, you can determine the minimum system size you'll need. Once you've determined that, you can determine how many solar panels you'll need, and find compatible components from there.

Can iuse all of my nonnal120/240 appliances?

Maybe! Many older homes were not designed or built with energy efficiency in mind. When you purchase and install a renewable energy system for your home, you become your own power company so every kWh of energy you use means more equipment (and hence more money) is required to meet your energy needs. Any appliances that operate at 240 VAC (such as electric water heaters, cook-stoves, furnaces and air conditioners) are impractical loads to run on solar. You should consider using alternatives such as LP or natural gas for water/space heating or cooking; evaporative cooling instead of compressor based AC units.

Refrigeration and lighting are typically the largest 120 VAC energy consumers in a home (after Electric heating loads) and these two areas should be looked at very carefully in terms of getting the most energy efficient units available.

Great strides have been made in the past 5 years towards improving the efficiency of electric refrigerators/freezers. Compact fluorescent lights use a quarter to a third of the power of an incandescent light for the same lumen output and they last ten times longer. These fluorescent lights are now readily available at your local hardware or discount store.

The rule of thumb in the renewable energy industry is that for every Dollar you spend replacing your inefficient appliances; you will save three dollars in the cost of a renewable energy system to run them. So, you can see that energy conservation is crucial and can really pay off when considering a renewable energy system.
