This wind and solar combo allows you to keep generating power for a small shed or RV even when the sun goes down.
We all know the price of solar panels is dropping, outpacing other renewable technologies. But not everyone, apparently, gets the same memos. I got a flyer in the mail today from Harbor Freight, which usually has rock bottom prices on everything. They have a 45-watt PV panel array "on sale" for $199. But why would I pay that much for 45 watts, when I can go to Amazon and get a deal like this Eco-Worthy 12 Volt 500W Wind Solar Power System for $442?
Is the offer too good to be true? Not exactly. You will be getting a good deal, but not quite as good a deal as it sounds.
The included solar panel is only 100 watts, and the wind turbine is 400 watts, which means that most of the time, it will be generating considerably less than 400 watts. On the plus side, the package comes with a solar/wind voltage controller and cables, so all you have to do is hook that 12-volt power up to a cigarette lighter type socket, and you're ready to power any small DC appliance or lighting.
If you're looking for a system to run appliances in your house, this won't get you there. But it's the perfect package for someone who has a small workshop with regular breezes and a sunny roof--or better yet, a snowbird who likes to go "boondocking" in the RV and take his/her power along.
