Although not a solar product per se, LED grow lights are an excellent load for solar power systems. In cold climates (like where I live) we have shortened growing seasons and many highly desirable plants like lemons, oranges, limes, kiwi, starfruit do not grow well here. The plants can be coaxed, but need to be given as much support in their early life as possible. A solar powered LED grow lamp can provide this extra energy they need to ensure good root development early in life as well as supplimental light durring the fall, winter, and spring. I like to think of a solar powered LED grow light system as capturing non-usable sunlight, storing it, and reimitting it at my selected target.
