Solar Power Solar Power

Solar power is the foundation for all life on earth! Solar heating has been used for thousands of years to warm just about everything—well, everything the light touches anyway. But solar electricity is a very new business. One of the new parts of the business to power things is through solar paneling.

Solar power technologies use reflective materials such as mirrors to concentrate the sun's energy. This concentrated heat energy is then transformed into electricity.

Solar panels have no moving parts at all. You just sit them out in the sun; hook up the wires, collect power and without adding fuel or replacing worn-out parts for many, many years. It's amazing that nobody has any idea for sure how long a solar panel will last. That's because many of the very first solar panels are still producing power today.

Used solar panels produce less power per square foot than new panels do, obviously. A modern solar panel might produce twice as much power as an old one of the same size--but will cost more than twice as much because of how the market is increasing. So what you can do is compare dollars per watt. The best current deal as of now on a new 50 watt solar panels is about $4.25 a watt--$212 for a 50 watt panel, in quantity. Other new panels of about the same size can create 120 watts, but cost $700--$5.83 per watt. The only difference is size--unless you have limited mounting space (rarely a problem), panels that cost the least dollars per watt are the best deal around. You just put up more of them and bam! You’re done!

Solar Power is becoming more of a popular alternative because people all over are just now starting to realize all the benefits that come with it. Rather than paying large electric bills in the summer and even bigger gas bills in the winter, with solar energy through paneling, it is the same low price all year round. It is clean; you don’t ever have to worry about there being a shortage causing your power to go out.

Homes designed for passive solar and day lighting put together design features such as large south-facing windows and home materials that absorb and slowly release the sun's heat. No mechanical means are used in passive solar heating. Using passive solar designs can reduce heating bills as much as 50 percent. Passive solar designs can also include natural ventilation systems for cooling.
