The sun shines everywhere, but not all the time. Combined with batteries, though, the hybrid system becomes fully dispatchable. Using a simple HOMER Pro model we show how much it would cost to provide a constant 24-hour source of energy using just solar and batteries.

Of course, it depends on a few factors, especially the total installed cost of solar and batteries and a couple of other factors listed below.
