The product list is meant as a guideline for your power needs. Air conditioners and residential refrigerators usually need more than solar alone — contact us or your dealer. Additional parts such as install kits, remotes or cables may be required.

How the RV solar calculator works
The calculator adds up the amp hours your appliances draw from a 12-volt battery bank each day. DC items such as lights, water pumps and fans are counted directly; 120 V items such as microwaves and TVs are converted to 12 V amps with inverter losses included. It then works out how much solar it takes to put that back: as a rule of thumb a panel returns about 5 amps per 100 watts for roughly six hours of good sun in summer (about 30 Ah per 100 W per day) and far less in winter, so the same loads need a bigger array for cold-season travel. It compares your draw with the usable capacity of your batteries and recommends a Go Power! roof-mounted or portable solar kit, an expansion panel if you already have solar, a Dometic Advanced Lithium battery bank if yours is unknown or too small, and an inverter sized from your largest 120 V appliance. When your loads outrun a standard kit, it connects you with a Go Power! specialist instead of guessing.
