To convert the DC Current produced by the panels into AC, panels are connected in series to produce effectively a single large array with a nominal rating of around 300 to 600 VDC. The power then runs to an inverter, which converts it into standard AC voltage, typically 120VAC/60Hz for the North American market, or 220VAC/50Hz in Europe.

Solar panels produce direct current at a voltage that depends on module design and lighting conditions. Modern panels using 6" cells normally contain 60 cells and produce a nominal 30 volts.

The solar tracking investment is less than 15% of the total investment of the power station and the generation can be enhanced by up to 25% for single axis tracking and up to 40% for dual axes tracking, thus it brings more payback for the investor of the power station.

Wind generators provide dependable energy for remote homes, water pumps,  telecommunication sites and rural applications in moderate to extreme environments.

For generations water has been used as a source of energy by industry and by a limited number of utility companies. In many countries accross the world, most rivers and streams capable of producing huge amounts of hydroelectric power have been harnessed; however, this does not preclude the possibility of using mini-hydroelectric power as a source of energy supply for home or farm.

In an incandescent bulb, the light-production process involves generating a lot of heat (the filament must be warmed). This is completely wasted energy, but LEDs generate very little heat, relatively speaking. A much higher percentage of the electrical power is going directly to generating light, which cuts down on the electricity demands considerably.
