If I was to ask you what solar roof panels are youd most likely say the large sheets of glass and silicon used to collect and store energy for the home. Well youd be half right. There is one other type of solar roof panel and that is a solar thermal panel which is used to heat water in both residential and commercial buildings. To start with the first type of solar panels let us talk about their usage and why businesses and residents may want to look into having them. The solar roof panels also known as photovoltaic panels work to create energy by separating the positive neutrons from the negative ones.
Solar roof panels are popular and often seen attached on rooftops all over the country usually on a south facing roof to catch the maximum amount of sunshine possible. Solar panels contrary to popular belief do not require sunshine to operate. All they require is light so while a nice sunny day will provide the maximum amount of light a dull cloudy day will still provide enough light for solar roof panels to operate efficiently. This makes them very attractive for while installation costs can be relatively high after that they are almost cost free to run and use.
One of the first things you should consider is placement. Where will the solar roof panel receive the most amount of sunlight? Facing the panels south is the best choice for optimum energy. Never face them to the north. You should make sure that you check with your local building department before you install the panels. Some areas require you to have a special building permit. Make sure you tilt the solar roof panel in relation to the latitude in which you live. There is a rule of thumb to follow for efficiency. 0-15 degrees latitude: 15 degree tilt 15-25 degrees latitude: tilt degree = same as latitude degree 25-40 degrees latitude: tilt degree = latitude degree + 5 degrees 40+ degrees latitude: tilt degree = latitude degree + 20 degrees
Newer solar technology has produced solar cells which can produce up to twenty percent efficiency a vast improvement of the seven to ten percent produced by the older solar cells. This improvement has improved the economics of solar power and makes the investment of a solar roof a more viable choice than previous systems. Using new technology your homes roof can provide not only protection from the elements it can be a valuable source of electricity. Make use of the sunlight falling on the roof which now goes to waste by using it to power all those electrical gadgets so necessary to modern life.
