Before installing a domestic solar panel system it is important to consider a few things. First of all it is important to find out how much solar radiation is available in your area.
Another important aspect is the roof of a building. The ideal roof has little shade and faces south, east or west. Also the pitch is relevant; tt determines the angle in which solar collectors are receiving solar radiation and is therefore relevant for the efficiency and profitability of a domestic solar panel system.
If you’re not sure if your home is suited for domestic solar panels, talk to an expert.
What does a domestic solar panel system look like?
Photovoltaic systems can be ground-mounted or integrated into the roof or walls of a building. PV modules can also be added after construction on top of the roof. A domestic solar panel system consists of solar panels, electric wiring, a meter and an inverter.
For a domestic solar panel system, panels are mounted on the roof and wired together. They generate electricity and send it to the inverter. The result is an 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 electricity than required, the extra power will automatically be sent to the utility. If it generates less, the additional electricity needed can be drawn from the grid as usual. The utility monitors how much power is used in the building and automatically measures how much of the solar energy is needed on site and that which can be transfered to the grid.
Feed-in-tariffs, net metering, rebates and incentives will have a positive effect on your electricity bill and contribute to making domestic solar panels more accessible and affordable.
