Futuresolar 12V 10W Monocrystalline Solar Panel Battery Charger

- 10W, Vmp 19.8V, Imp 0.55A
- 7.8 x 14.9 x 0.67 inches
- 10-year 90% output warranty
Our take
Anyone with a controller on hand and a tiny load to hold up gets the lowest outlay here.
Why it made the shortlist
Bottom of the price order: a 10 watt monocrystalline panel with a stated 19.8 volt maximum power voltage, 0.55 amp current and 23.4 volt open circuit voltage. It measures 7.8 by 14.9 by 0.67 inches.
A 166 millimeter cell supports higher efficiency and longer life.
Pre-drilled holes on the frame make mounting fast.
The warranty terms are clear: two years on materials, 90 percent output at ten years and 80 percent at 25.
Gate openers, electric fences, chicken coops and lawn tractors are named uses alongside boats and vehicles.
What works
- Published electrical specs
- Long output warranty stated
- Pre-drilled frame for mounting
Watch out for
- No controller included
- Ten watts barely tops up a battery
