solar panel electricity output
A plurality of series connected solar panels are classified into three categories:
* 15 to 16 volts – 30 to 32 cells per panel
* 16.5 to 17 Volts – 33 to 34 cells per panel
* 17.5 to 21 volts – 35 to 36 cells per panel
15 to 16 volt panels are called self-regulation of the panels, because they do not produce enough voltage to overcharge batteries, resulting in gas chambers. For this reason, do not require a charge controller as other groups do. This reduces the cost and maintenance of a system. These are known as battery maintainers, and are excellent for use in small systems with a battery if the system has a lot of energy drain. Electric fences and other low power applications that have limited energy use can use these types of solar panels.
16.5 to 17 volts of the panels are suitable for total energy systems fully in places that usually get a lot of sun around the year.
The most preferred group of applications is a solar charging panel of 35 to 36 cells providing 17.5 to 21 volts open circuit voltage. A panel of 36 cells recommended for very hot climates in order to offset the loss of output of high temperature. Also to compensate the voltage drop in the systems with long cable runs.
Watt Designer
Design Power is simply the open circuit voltage multiplied by current shorted. Designers use this figure to group the rate of the components used in the panel and the peripheral components.
If you offer a panel of about 20 volts open circuit and 3.5 amps of short circuit current, the power of design will be 70 watts. The components of the system must be capable of handling 70 watts, 3.5 amps and 20 volts.
A group of 70 watts nominal designer will probably give about 54 watts on actual usage and will vary depending on the target = "_new"> the efficiency of the cells, as well as other conditions.
