small solar electric systems
 |
A small solar electric or photovoltaic (PV) system can be a reliable and pollution-free producer of electricity for your home or office. Such systems are becoming more affordable all the time. Small PV systems also provide a cost-effective power supply in locations where it is expensive or impossible to send electricity through conventional power lines.
Because PV technologies use both direct and diffuse (scattered) sunlight to create electricity, the solar resource in many inhabited parts of the world is ample for small solar electric systems. However, the amount of power generated by a solar system at a particular site depends on how much of the sun's energy reaches it. Thus, PV systems, like all solar technologies, function most efficiently in regions such as the southwestern United States and southern Europe, which receive the greatest amount of solar energy.
You can also use PV technology to provide outdoor solar lighting.
