Solar insolation for a typical North American latitude.
When electrical demand for a residence or other load type, is at the opposite "phase"
from the solar radiaton available in most locations that is not an optimal solution either for "grid-tied" or "off-grid" loads. Storage is required!
If the power production could be shifted to match the demand curve it yields a much more efficient system.
With SunSmart Adaptive Generation the microcontroller can sense the peak requirement time and then ramp up the generator to produce peak power for the high demand curve. The system then shifts to the recharge cycle when the demand drops off.
