Home Solar Systems

Home solar system and its apraisal.

The sun, as an endless source of energy, can solve the problems of energy and the environment. Unfortunately, cheap energy and high bank profits make spending in the solar system in our country not cost-effective if they are very cost-effective in the long run and have a significant impact on reducing air pollution. Will also have. Each square meter receives about 1000 watts of radiation from the surface of the sun - in one day without clouds and pollution. The average radiation level in Iran is about 850 watts per square meter. The solar panels in the commercial market have an efficiency of about 12 to 17 percent, and given that the entire surface of a solar panel does not contain silicon, they can receive about 100 to 150 watts per square meter of these panels. It should be noted, however, that this amount of energy is in the form of sunlight perpendicular to the panel and the angle of the panels in the different seasons of the year should be adjusted. Solar power system used in a home: On Grid: In the system connected to the grid, the solar energy will be fed to the grid. In fact, in this system, the customer sells electricity to the New Energy Organization of Iran (Ministry of Energy). In this way, the electricity produced will be fed to the grid after being converted by a special inverter for systems connected to the network and using special double-sided meters. In this case, the customer has actually built a small solar power plant in his own house, which, according to the capital and space, could build one to 20 kilowatts of power plant houses.
