PV Solar Panels


PV Solar panels convert sunlight to DC electrical energy.

Solar panels range in size from 1 watt to 300+ watts. Most solar panels up to 135 watts are 12 volt. Most solar panels over 135 watts are 21 to 40 volts - designed mainly for grid tie applications.

High voltage panels can be used on off grid battery charging systems when using MPPT controllers. These controllers will step down and transform the voltage from the solar panels to the battery bank voltage.

All solar panels are rated in Watts. The watt rating is how much power (amps times volts) the panel will produce in full sunlight at 25 degrees C (77F). This is the industry standard (STC) for all PV panel ratings.
