Before installing a residential solar power system some considerations are necessary. First, it is important to find out how much solar energy, or more precisely, solar radiation is available in your area.
Another key consideration is the roof of the building. The ideal roof has only little shade and faces south, east, or west. Also, the angle of the pitch is relevant, because it determines the angle in which solar collectors are receiving solar radiation. This impacts the overall efficiency and profitability of a residential solar power system. If you are unsure whether your home is suited for a residential solar installation, talk to an expert in your area.
What does a residential solar system look like?
Photovoltaic systems can be mounted on roof, on the ground, or integrated into the walls of a building. PV modules can also be added after construction on top of the roof. A residential solar power system consists of solar panels, electric wiring, a meter, and an inverter.
For a residential solar system, solar panels are mounted on the roof and wired together. They generate electricity and send it to the inverter. The result is alternating current which can be used directly or fed into the grid.
How Can I Feed Solar Energy Into the Grid?
If an installed solar system generates more solar power than needed, the extra power will automatically be sent to the utility. If it generates less, electricity can be drawn from the grid as usual. The utility monitors how much power is consumed in the building and automatically considers the amount of solar energy that is used or fed into the grid.
Feed-in-tariffs, net metering, rebates, and incentives will have a positive effect on your electric bill and make residential solar power more affordable.
