Solar Panels, Power, and Roofs

Welcome to MillionSolarRoofs.com. Solar roofing is one of the most recent ways mankind has developed solar power to suit their needs and lower the carbon footprint of humans. With the abundance of unused roof space and the abundance of solar energy, it will quickly become the most practical form of harnessing energy especially as other fuel costs continue to rise and traditional fuels become more difficult to find.

Solar energy is defined as radiant energy that is produced by the sun. There is more energy radiated to the earth from the sun in one minute than people have used since the beginning of time. The difficult part is harnessing that power, and turning it into a form that is usable and efficient.

People began harnessing the sun’s power as early as the 7th century B.C. Lenses and mirrors were used to ignite wood. Not a lot changed for thousands of years. The sun was still giving power to people, but in a passive way, heating homes during the day and providing natural solar lighting. It was not until the industrial revolution that solar power became more efficient and popular.

The first breakthrough was in France. A scientist used heat from a solar collector to boil water and drive a steam engine. Another important development was Charles Greeley Abbott’s efficient solar boiler in 1936. Residential solar water-heaters gained popularity in the southern U.S. states in the 1920s, until cheap natural gas became the primary fuel for heating after World War II.

Current energy situations have caused a huge increase in the amount of research and development of solar power, mostly because of the low solar power cost. Unlike coal and gas which must be mined or pumped, the sun’s rays are widely available for anyone to use at any point. Portable solar power can allow people to generate electricity or heat water anywhere there is direct sunlight.

The problem with buying solar panels is the current high cost of photovoltaic cells, and the inefficiency of batteries that store the converted energy. Once the initial investment is completed and solar panels are installed, there is very little maintenance, and surplus power can actually be sent back to the power company for a profit through grid tie solar connection.

The most modern way to generate electricity from the sun is through the use of photovoltaic solar panels, or solar modules, which were first discovered by Henri Becquerel. They are generally made from thin wafers of silicone, and when charged particles from the sun hit them, they convert the sun’s photons into usable direct current (DC) electricity. With the addition of a solar inverter, the DC power can be converted into alternating current, or AC power, which is what most electrical appliances utilize.

Only about 14% of the photons that hit the photovoltaic cell are converted to electricity, but this is four times what it was five years ago, and is predicted to increase at an even faster rate.

Some other ways of collecting the suns power are with passive solar power and concentrated solar power. A passive system is generally used to keep the temperature of a home or building consistently warm, but not too hot. It achieves this harmony by design, instead of by any active action which requires almost no maintenance. The walls of these places are much thicker, so the exchange of heat is much slower. The walls will be warmed by the sun during the day, and keep most of the heat during the night, only to get warmed the next day. Most windows are placed to the south to collect heat during the day, and covered at night to keep the heat in.

A greenhouse is one example. With concentrated solar power, an array of many mirrors angles the sun’s rays onto a receiver panel which contains liquid. As the panel heats the liquid, it is sent to a turbine to generate electricity. To keep the receiver panel hot, all the mirrors must rotate with the sun for it to be effective. This requires more maintenance, making it less efficient.
