Rooftop solar panels also come with inverters that convert direct current electricity into alternating current (AC) which is used by many devices and home appliances like computer, televisions and even washing machines. Rooftop solar panels rely on the ability of the solar cells to harness the energy of the sun and convert it to electricity.
The device that makes this change is called an inverter. The photovoltaic effect is the key to making solar energy into electricity. Sunlight hits the panels, exciting the electrons and creating an electric flow. This is how a rooftop photovoltaic system turns sun energy into power for homes.
Rooftop solar panels rely on the ability of the solar cells to harness the energy of the sun and convert it to electricity. It is a small, square-shaped semiconductor that is made from conductive materials such as silicon.
The larger the surface area required to support the PV system, the greater the potential impact on the building structure. The use of rooftop solar panels increases the superimposed dead load (SDL) of the roofing system and can have varying impact on a building depending on what material is being used for the structural system.
For a steel or wood low rise building, the relative additional weight from rooftop solar panels can add approximately 10% to the total factored design load of the roof structure. However, when considered in light of the total building costs, this additional costs may prove to be minimal.
Take into account the roof orientation of the panels and ensure that the mounting framework is slightly tilted, usually between 18 and 36 degrees. Some companies use solar trackers to improve the efficiency of energy conversion. Following the mounting setup, the solar panels are securely attached to the mounting structure.

Design Guide for Rooftop Solar
Solar power is produced by converting sunlight into electricity. The two major methods of converting sunlight into electricity are photovoltaics (PV) and concentrated solar power (CSP). CSPs utilize mirrors and tracking systems to concentrate sunlight onto a small heat collector. The concentrated heat is then used in conventional power plants [1].
