The sizing of the solar module needs to be adequate 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 used and the expected usage of these appliances. If you don't feel comfortable estimating these factors yourself, please feel free to contact our technical staff. As a guide a small 5-watt module is sufficient to maintain the charge on a battery infrequently used for boating. An 80-watt module is typically used by caravan owners seeking to power lighting and small appliances, and 10 individual 150-watt modules for a small residential home.

Manufacturers typically give a warranty of 20 years on output. They are able to provide this, as there are no moving parts or chemicals to break down. The workmanship warranty is typically 2 years and covers such items as frame assembly, laminating and electrical connections.

Solar panels are design to charge a range of batteries with sufficient voltage to ensure optimum current flow to the battery. To ensure that batteries are not overcharged and permanently damaged, a charge controller is desirable to limit the battery charging when the battery nears a fully charged state. The charge controller is placed between the solar module and the battery to regulate the charge.

Batteries are rated in amp hours and the solar module is rated in watts. This may be translated to the rate of charge in amp hours (Ah). As a guide, a 10 watt module will charge a battery at approximately 0.6Ah in bright sunlight. If the battery is rated at 6Ah capacity it will take a little over 10 hours to charge the battery from a discharged state.

All Green Systems supplied solar panels have a solid aluminium frame permitting the user to bolt the frame of the solar panel to a fixture, typically a backing plate or mounting arrangement.

It is desirable to keep the connection wires as short as possible to reduce voltage-drop due to cable resistance. Your solar module will charge a battery with at least 6 metres of standard cable and further with heavy-duty cable.
