ALLPOWERS SP039 600W Foldable Solar Panel

- 600W, 44V output
- 27.5 lbs, 23.6 x 35.7 x 1.9 in
- IP67 with XT60 and extension
Our take
A 600W panel with the lowest price and a weight under 28 lbs.
Why it made the shortlist
The ALLPOWERS SP039 is a 600W panel with a 44V output, six foldable panels and a folded size of 23.6 by 35.7 by 1.9 inches. It weighs 27.5 lbs, uses monocrystalline cells up to 23 percent efficiency, and carries an IP67 rating.
Against the EYONGPV and Generic 600W, it costs far less and weighs about 3 lbs less than the Generic. It ships with an XT60 cable and a 1.5 m extension and targets ALLPOWERS S2000 Pro, R2500 and R4000 generators.
It suits owners of large ALLPOWERS generators and any station with a 44V-friendly input. It balances 600W, weight and price better than the other full 600W panels.
What works
- Lighter than the Generic 600W
- Named for ALLPOWERS generators
Watch out for
- Folded length is long at 35.7 inches
- Efficiency is lower than the HPBC panels
- The catch
- A 44V output needs a station that accepts it.
