Residential solar energy systems are designed on a case-by-case basis. Homeowners have different electricity needs, and because every rooftop or ground installation site is unique, photovoltaic system configurations are individually planned.
That said, most residential photovoltaic power installations share the same types of components. These are the primary components needed for a home PV system.
Solar panels are the foundation of any home PV system. Made of dozens of solar cells, the panels absorb photons of light from the sun and transform the particles into an electrical current — a phenomenon known as photovoltaic effect. The more electricity a home uses, the more photovoltaic panels are needed.
The photovoltaic effect produces direct current (DC) electricity, but home electronics and appliances require alternating current (AC) electricity. Inverters take the DC energy from the photovoltaic panels and convert it to usable AC energy. For residential solar energy systems, either micro-inverters or string inverters can be installed.
Most residential photovoltaic power systems are installed on rooftops, using mounting components specifically designed for residential solar panels. The racks typically require installers to make some holes in the roof, but special flashing is used to create a watertight, leak-free seal. Ground-mounted solar energy installations use metal poles and racks made to support the panels at the ideal tilt and angle.
In a home PV system, the photovoltaic panels are wired together into a string, and the string is wired to the inverter. Or, if micro-inverters are used, each one is connected to a separate panel. The wiring is then attached to the home grounding system and connected to the grid with the net meter from the local utility company. The net meter allows electricity to flow between the home and the electric grid.
Residential solar energy systems often have in-home production meters to track electricity production. Many homeowners also opt to have web-based monitors installed to more easily observe their home PV system output and understand patterns in their household energy usage. Monitoring systems also alert homeowners to changes in electricity generation, which means they can be addressed more quickly.
