Selecting a Solar Module
The sizing of the solar module needs to meet the load demands of the appliances you wish to use. There are a number of calculations needed. These include the amount of sunlight available in your location, the number and load drain of the appliances and the expected usage of these appliances. As a guide, a small 5W module is sufficient to maintain the charge on a battery infrequently used for boating. An 80W module is typically used by caravan owners seeking to power lighting and small appliances. Twelve 120W modules would be sufficient for a small residential home.
