If you have you been questioning if you should install solar panels on your house, there are several factors to consider. The direction your roof faces can make a difference as well as the placement of your trees. You will also need to know if you want your solar power system tied to the local utility grid. Following is some information to help you decide if solar panels are for you.

An important issue is deciding whether your system will be grid tied or off grid. Grid tied means that your electric system will be hooked up to the local electric utility company. While sunlight is shining on 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 be powered by utility company electricity.

An off grid system runs independently and is not connected to a utility company. They are more found more in rural areas where utility poles may be too far away and getting hooked up is extremely expensive. Off grid systems have batteries (similar to car batteries) to hold excess electricity, and usually have back up generators for emergency situations. Appliances get their electricity from the solar panels during the day, and the batteries or generator at night or during inclement 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 placement of your solar panels. For maximum efficiency solar panels need direct sunlight for as much of the day as possible. Large trees that shade the roof as well as taller buildings that could block the sun need to be considered. Since each house has a different combination of these factors, each house must be individually assessed. Accurate measurements and surveys, as well as a site inspection by a qualified installer will give you the necessary information to choose the best solar panel configuration for your home.
