The solar panel installation cost process varies by location, and it is important to choose a reputable solar installer that has a strong local reputation and an excellent track record. A good installer should also be licensed or certified to carry out electrical work in your home, and they may be part of a national program such as Solarize, which can offer you a reduced system price.
Your installer will assess your house for its suitability to solar energy based on your annual electricity usage and the amount of sunlight it receives in your region. This assessment will include a visit to your roof to determine whether it is suitable for solar panels. It will include checking that the roof is free of obstructions and that the solar panel layout allows sufficient unobstructed sunlight throughout the day.

A roof mount or ground frame is then mounted on your home, or in the case of a ground-mounted system, in your yard. The solar panels are then connected to each other in either a series or parallel configuration. A series connection has the positive (+) and negative (-) wires of each panel linked together, which improves voltage matching with your electricity system.
The inverter is then connected to the circuit breaker box in your house, which converts the DC electricity from the solar panels into usable AC electricity. A generation meter is also usually connected at this stage, which will enable you to monitor how much solar power your panels are producing.
