Residential solar systems, also called photovoltaic (PV) systems, convert sunlight into electricity by using solar panels. Solar panels consist of many small photovoltaic cells that are connected together to form a module. When sunlight hits the cells, it excites electrons and causes them to move, creating a direct current (DC) electricity. An inverter converts the DC electricity into alternating current (AC) electricity, which can be used to power homes.
There are several advantages of using residential solar panels, including:
If your home is equipped with solar panels, and the panels are connected to a battery backup system, you may still have electricity during a power outage, depending on the size and capacity of your solar system. However, if you are connected to the grid and do not have a battery backup, your solar system will not work during a power outage for safety reasons.
The amount you can save on your energy bills with residential solar panels depends on various factors, including your location, the size of your solar system, and your energy consumption. However, research shows that homeowners can save between $10,000 and $90,000 on energy bills over 20 years through the use of solar panels.
