Photovoltaic solar panel system generates electricity by using the sun energy. It makes use of photovoltaic materials usually silicon that produces power when exposed directly to the sun. So how much electricity does a PV solar panel system output?
A typical solar panel can generate 1KW of electricity for each 100 square feet. Some PV systems though are more powerful. The answer will depend largely on the kind of system you install.
For a typical home, this power generating capacity allows homes to save as much as 40 percent off their monthly electric bills. The cost of installing a photovoltaic will be paid by itself after several years of use. A PV technology usually lasts 25 years or so.
When the sun is at its strongest, usually around 1pm, the power generated by the system may surpass the household demand of electricity. But after 1pm, the amount of solar electricity generated might decrease. This will shift electricity use to conventional power.
In a 1.5kW PV system, the amount of power produced daily can run up to 7.3kWh of electricity. If a typical household uses 20.5kWh of power daily, this means the PV system does not fed power into the grid since all power produced are consumed by the house.
Another factor that can determine the power output of the PV system is the number of solar panels you can fit into the roof. You have to place the panels in a spot where you can get the maximum energy of the sun. Face the panels to the south side where the sun in the UK is generally situated.
Try to make sure that nothing will block the sun rays from getting to the PV system. Trees, tall buildings and other structures might block the sun. The amount of electricity the PV solar system creates might not be sufficient for the house if there is an object is impeding it.
