FAQS about Solar power automatic charging circuit during daytime

How long does it take to charge a solar panel?

Due to low current, battery needs 18 hours to fully charge the battery but sunlight is only available for 12 house max. in conclusion at the night time the switching circuit and LED light consume 10 to 12w of power from battery and at day time the solar panels refill the battery. Little bit tricky but its work!

When should solar panel continue charging battery?

1. Solar panel should continue charging battery not beyond 56 V. 2. In the event of battery discharge, the charging process should resume again only when it reaches 48V. In other words hysteresis should be maintained. 3. Battery should continue supplying power to load when battery voltage remains in between 42 - 56V.

How does a solar panel charge a battery?

The solar panel supplies the peak voltage of 6 V, at 500 ma during daytime, which charges the battery as long as this voltage is available from the solar panel. The resistor Rx keeps the charging current to a safe lower level so that even after the battery is fully charged, the minimal current does not harm the battery.

How does a solar battery charger work?

The circuit normally charges the connected battery at constant current through the power received from the solar panel, and reverts to DC power from an AC/DC adapter in the absence of solar energy (during night time).

How does a solar controller circuit work?

The controller circuit is expected to perform as follows. 1. Cut off solar supply to battery when its voltage reaches approx 56V and maintain appropriate hysteresis to avoid frequent switching of power MOSFET. So the solar supply to battery would resume again only when the battery voltage reaches approx 48 V. 2.
