Great product. Works well

Solar panel is solid and well made. It provides a welcome and practical alternative to a gas powered generator.

Worth it!

Super easy to use flat or even with the included stand. Charging in a zip too. You can PARALLEL connect 4 on the Delta Pro.

Good product for portable solar power uses.

Performs well and as expected. It has a good conversion rate/performance. I have good sun exposure most days of the year and can recharge in 4-5 hours when 2/3's expended. The panel array is heavy and awkward for single person manipulation. The panel array gets warm as would be expected in the sunlight and so if laid out over vegetation that you care about, (lawn, etc) it will burn the vegetation - I have had the same issue with a generic tarp on the lawn. So I purchased an adjustable stand that folds up and that solves a lot of the issues.

Great performance poor stand method

Case standing system awkward and difficult, folding leg on panel would be much easier.
