Solar panels convert sunlight into electric energy. The panels are connected in series and/or parallel to provide the voltage and current levels to meet your
needs. Solar
panels are normally placed on roof tops with the most exposer to the sun. Most solar panels generate
around 100 to 200 watts in bright sunlight. Depending on your energy needs, you may need to link many units together.
Solar panels vary in length and width, and are often about 2 inches thick. Framed modules are the industry standard.
They are the most cost effective, and applicable for most applications. You can purchase foldable solar panels that
are lightweight (less than 5 pounds) and can fold up and fit easily in a backpack. Many people use rollable panels
on boats because they are durable and can be easily stowed after use. Roofing solar panels (laminates) are becoming
more common, but are still available on a limited basis for now. Generally these thin-film laminates are more expensive per
watt and require more square footage to produce the same wattage of an equally sized framed module. Solar roof shingles are inexpensive
solar panels that don't produce as much power as their big brothers. But because of the price and simplicity of the
rack used for mounting and the ease of wiring them, you can cover your entire roof with panels (or at least the side facing
south). Older
panels are either 12 volts or 24 volts, and would be connected in series to produce 48 volts. Now 48 and 65 volt
systems are the norm and 12 volt systems are becoming very rare. The higher voltage results in a much more efficient
array due to lower line losses. These panels can't be connected directly to a battery bank, they require a controller.
Shopping Dollars
per Watt is the best way to choose solar panels.
Join the millions
of people calling on our leaders to Repower America with 100% clean electricity within 10 years. With energy sources depleting at a rate faster than they are being
built, it is only wise that we use the abundant energy available for free (solar energy). Apart from the easy availability,
solar energy helps control environmental pollution. Most
of us shy away from installing solar power solutions at home thinking them to be expensive and cumbersome. You will, however,
be surprised to know how easy it is to employ these power solutions. Moreover, these will help cut down your power bills.
Finally, you will be delighted to know that you are doing your bit to save our resources for the future generations.
