Solar Photo Voltaic Panels (PVs) give out DC power and LED Lights natively use DC power. DiyaStar® enables direct piping of solar energy into lights, fans and motors.
This differs from conventional application of solar energy to charge batteries which is then generally used when power fails. This was a necessity which met functional requirements.
When solar power is inadequate, say, during dawn and dusk, at night or when the sky is overcast, another small solar panel (about 5W) and an electronic circuit cuts off the power from the panel to devices.
As soon as the power is cut off, another cirucit closer to the device hooks on to Grid Power which is in stand by mode and vice versa; aka, FREE Energy FIRST.
