By tying the solar system to the utility grid, excess electricity that’s produced can be “sold” back to the utility or credited to the producers account and used to offset times when the solar system isn’t producing sufficient power for the home.
One of the first decisions to be made with regard to installing a PV Solar System for your home is whether to use a roof mounted or ground mounted PV system.
* Roof Mounted PV Systems – Roof mounted PV systems are typically the least expensive to install because the roof becomes the supporting structure.
While this type is often the cheapest, it comes with some compromises such as: roof penetrations, fixed orientation to the sun, extra roof loading on your home, and the need to remove the panels when new roofing is needed.
