Solar power makes use of photovoltaic devices or, as they are commonly called, solar cells. These devices generate electricity directly from sunlight. The electrical energy from the solar cells can be used to power buildings and homes.

A solar electric system does not heat water directly. Solar electric systems generate electricity, which can be used to heat water in an electric water heater.

Solar thermal systems heat water or other liquids through piping systems that are exposed to sunlight.

Your primary source of power will continue to be your existing electric utility. Your system will generate electricity which can be used for your power needs, but it may not be sufficient for at all times.

Any excess electricity generated by your system will flow into the electricity grid supporting your community. You will receive credits on your electric bill for these contributions.

During a power outage, any private solar electric system without generator backup must shut down until utility power is restored. This is done for safety reasons and is required by law.

This means that if the electric utility company in your area experiences a power outage, your solar electric system will shut down as well. Thus, the reliability of your solar electric system is tied to the reliability of the electric service you receive from your electric utility company.

A solar electric system and all of its components will typically operate for more than 20 years. The basic solar module has no moving parts and can last more than 30 years.

Since there are no moving parts, solar electric systems are practically maintenance free. Rain will typically provide adequate cleaning of the solar modules.

Solar electric systems are at peak performance when they are receiving direct sunlight. However, they are designed to operate in cloudy or foggy conditions as well. When systems receive little light, for example on dark, overcast days, they will not generate as much electricity.

A solar electric system is not adversely affected by cold weather because it is light and not heat that causes solar cells to generate electricity.

“Net metering” allows you to “bank” any surplus electricity your system generates on the electric grid. For example, excess electricity might be generated during the day when your system produces more electricity than you use.

During this time, your meter would simply run backwards to record the amount of electricity your system has banked into the grid. Later, you can use an equal amount of electricity without incurring a cost.
