Solar Array Calculator
Enter the daily energy requirement and select the seasons you will be using it in. The result tells you the amount of solar generation needed in Watts peak. For example, if the answer is 100 Wp, then you need two 50 Watt solar panels, five 20 Watt panels or any other combination that adds up to 100 Watts. The actual panels to be used may be determined by their availability, the area available to you or other considerations.
To use this calculator, just input the daily energy consumption and select the season the system will be used in. The value returned is the minimum peak wattage required.
Please note: The results of this calculator are approximate and apply only to South Africa. Please have a look at the design section in the solar intallation guide for more information on insolation and the formulas used to calculate.
