What Are The Pros And Cons To Solar Energy
By Gavin Dye
Using the power of the sun to power our lifestyles, on paper looks like a natural fit. As with all things in life there are two sides to any argument and Solar Power is no different, so hopefully in this article I will answer what are the pro

Solar Energy?
Me and my husband is planning to build a new home in Austin TX and we wanted to be 100 free from electric bill using the sun energy. Anybody who have knowledge about PV, Solar Panel please I need your help.
Project Plan: 2500 sqm floor plan
5 bedrooms
What type of PV or Solar Panel Cell we need?
How much do you think it will cost?
Do you know an architect or builder who provide custom plan
Do you know somebody from Austin is using Solar Panel
Do you know local manufacturer that we can contact with?

solar energy?
anyone know any state grants or home loans for home solar energy for southern california. thank you
As a former Californian I have looked into this and found the only help is after the fact. There are rebates, and tax breaks once you have a system installed and running. If you produce any excess power, you can go out and watch your meter spin backwards! And by law, the power companies must buy all the excess you can produce. Now That’s pretty cool
SOlar Energy?
3 Examples of how solar energy is used.
Solar energy is used as follows:
It heats and lights the earth, without it we would all die on a very cold rock with no plant life.
Photo voltaic cells can collect solar energy and produce an electric current.
Solar collectors, usually roof mounted, are used domestically to heat water in homes.
Some desert areas use an array of mirrors to heat water in a central tower to produce steam to turn a generator and produce electricity.

How does the angle the light makes (Ex. the angle of the sun’s rays) with the surface affect solar energy?
here the experiment
The inside of a shoe box was insulated using Styrofoam and a thermometer was placed through a hole inside the box. Two absorbing surfaces were made from aluminum foil. The upper surface of one sheet was painted black and the other left shiny. The following tests were then carried out.
A sheet of shiny aluminum was placed in the bottom of the box. The top of the box was covered with glass and the temperature of the air inside the box was recorded. The lamp was then turned on and the temperature was recorded after 3 minute.
The procedure was repeated, this time using the blackened aluminum as the absorbing surface. Three set of data were collected. One test was done with the glass cover, one without the glass cover and the third with a glass cover but at an angle of 45º.
The most efficient angle for transfer of solar energy is 90 degrees so there is minimal immediate loss of energy to reflection. The further away the angle of the incoming rays of light from a line perpendicular to the surface of the collector, the more reflection of the light there will be and the less energy will be collected (comparatively).
Solar energy- does anyone know of a DIY way to make a solar collector and transfer that energy to batteries?
I would like to learn about solar energy and how I can make some panels for my home, of course with in a reasonable budget. My goal is to be able to run a refrigerator and fan off of battery. Any ideas out there?
