Use a multimeter (not included) to accurately read the panel’s voltage. Under full sun the multimeter should read 20-22 V DC.

There are many elements in this calculation. The size of the battery capacity and availability of sun are the two most important considerations.

The solar panel has an integrated blocking diode to prevent any discharge at night.

Yes, the solar panel has been weatherproofed and can be mounted outdoors without any additional protection.

It is recommended to use a solar charge controller (not included) for permanent installations to a 12 V battery.

This solar panel is a 12V battery charger. To run 110V appliances from a battery you will require a power inverter (not included).

Additional connection cables should only be purchased through the Sunforce Website www.sunforceproducts.com.

Yes, this panel comes with a 25-year limited warranty.
