They say solar power is getting cheaper and cheaper, and Amazon’s hastening the trend with today’s Gold Box.

These 100W panels are ideal for RVs, boats, golf carts, tool sheds, or any other smallish application, and they can even flex up to 30 degrees to contour to whatever you’re installing them on. You’ll still need a charging controller, a battery, and an inverter, but you can find some suggestions in Amazon’s related items, if you don’t already have them.

Today’s price is about $40 less than usual, and an all-time low, and you can save an extra 5% when you buy two, or 10% when you buy five. Just check out the special offers section on the page for details.
