All solar energy is free.

Not using enough solar panels or total output to match the needs for what you would be using it for. Small solar panels (35-100 watt) are great just to keep 1-4 batteries charged when not in use but if you plan to be running an inverter and powering appliances, living quarters in an RV or larger scale living, that if when you would need A LOT of solar panel and a basement full of batteries to use at all times. A lot of money would be spent on the panels and batteries but if you do not have the right equipment to control the electricity and monitor everything, you may be better if donating the money to a good charity where it will be much more useful and greatly appreciated

I have built a wind generator and have a schematic in simple terms

Passive solar energy can be used to keep buildings warm. Some buildings have large windows on the side of the building the sun hits. The sun's ray go through the windows and penetrate the heat-absorbent floors and walls. At night, this heat is released into the building.

The space industry was one of the first industries to adopt the use of solar energy. It started using solar technology on spacecraft in the 1960's.

I just found this on the Home Science Tools site. The instructions here are for kids, but they do say they will need an adult's help, so I hope it's what you were looking for:http://www.hometrainingtools.com/build-a-solar-oven-project/a/1237/

The first solar cell was built by Bell Labaratories.

Vestas, a Danish company, is currently the world's leading manufacturer of wind-turbines.

the largest solar panel in the world is nearing completion in Abu Dhabi.

Edmund Becquerel first hypothesized that light could be turned to energy in 1838, but the first solar powered motor was made by Auguste Mouchout in France a few decades later

technically, wind was first used to power sailboats thousands of years ago. Heron of Alexandria used wind to power his windwheel in the 1st century, which was the earliest record of using wind to power a machine

83. denmark uses wind for over 25% of its power
