Do Solar Panels Really Work On The Domestic Front?
If you are questioning whether your house is a good candidate for solar panels, here are several things to consider. Factors such as the direction that your roof faces and the location of trees on your property can make a difference. In addition, you will have to decide if your solar power system will be tied to the local utility grid. Here’s a short list of some of the things you will need to keep in mind.

The most important issue is whether your system will be grid tied or off grid. “Grid tied” means that the solar electric system is hooked up to the local utility company. While sunlight is hitting the solar panels, they will be generating electricity to power your appliances. At night and during periods of time when the sun is obscured, your appliances will run on utility company electricity.

An off grid system runs independently and is not connected to a utility company. They are more common in rural areas where utility poles are distant and getting hooked up is extremely costly. With off grid systems, excess electricity is stored in batteries (similar to car batteries) and a back-up generator is usually utilized. Appliances are powered by the solar panels during daylight hours, and the batteries or generator at night or during bad weather.
For either system-grid tied or off grid-roof pitch and facing direction, and objects that can block sunlight all play a part in where to place your solar panels. For maximum efficiency solar panels need direct sunlight for as much of the day as possible. Both trees and structures which might obscure the sun need to be considered. Of course, each house can have a different combination of these factors and should be assessed individually. Accurate measurements and surveys, as well as a site inspection by a knowledgeable installer will give you the necessary information for the best solar panel configuration for your home.
