Solar Electric Systems

 
Solar electric systems usually make use of photovoltaic (PV) panels, basically a set of treated silicon cells arranged in a series string that produces electric power when exposed to light. There are four common types of photovoltaic panels: monocrystalline, polycrystalline, amorphous and vaporware. Here are some reasons why you need photovoltaic cells to power your solar electric systems:
 

1. Solar electric systems put money in your pocket. This is especially true during the summer and winter months, and you’ll see a marked difference in your electricity bill. For maximum savings, fit your solar panels in the area of your home that can get the most direct exposure to sunshine. If you use a grid-tie inverter, you could potentially get credit from your power company for any surplus solar energy you produce.

 

2. Solar electric systems are perfect if you own a vacation home or cabin in a remote area. PV panels change sunlight directly into electricity with no moving parts, no maintenance, no fuel, and no greenhouse gases. For major energy efficiency, try using special solar lights, refrigerators and freezers that use about a quarter as much energy as typical models do.
 

3. Solar electric systems can be used anywhere there’s direct access to sunlight. For most of the day, your home should have free access to the sun. The south will generate more PV electricity than the north in this hemisphere, and inland regions have more sunny days and can potentially produce more electricity than coastal areas.
 

If you hire a contractor to help you set up your solar electric systems, ask him or her to give full, written instructions on how to maintain them correctly and safely. For example, shutting down the system in emergencies and powering it up after it has been shut down are basic safety requirements and situations every member of your household should learn to master.
