Four happy solar panels, 175 watts each. They have been soaking in the post-hurricane rays and leaving us running on our normal routine. We don't have heat or air conditioning (we plug into the dock power for that), but with perfect day and night temps right now that's not an issue. We just let the sun dance on the solar panels.
(even overcast or late day sun gives us juice!)
Then this little gizmo regulates the charging...And our AGM batteries store all that power so we have it at night when the sun is not shining.
No moving parts. Nothing to break down. Quiet. Reliable. Seriously, why do we bother with any other power source? So if you're local and your ice cream is melting and your milk is souring, bring it on by.
