The setup of a Solar Power Plant. whether large or small, is fairly simple. Setup an array of Solar Panels on rooftop, connect them to a Solar Charge Controller and
In the circuit above, the current from the solar cell flows through D1 to charge the Li-ion battery. When there is less sunlight, the higher voltage from the battery cannot flow back to the solar cell. Because there is a D1 blocking it, the current can flow only one way. The energy in the battery is stored and gradually increases until it is full.
The above design can be also integrated with an LM338 charger circuit as shown below: The sixth design here explains a simple low cost solar pocket LED light circuit which could be used by the needy and, underprivileged section of the society for illuminating their houses at night cheaply. The idea was requested by Mr. R.K. Rao
Separate DC or Solar Input - Two pads on the edge can be used to connect a 5 ~ 18V power supply, which can be used instead of USB. If the input is a solar panel, the charging chip will adjust the current draw so that the voltage does not dip below the battery, thus optimizing the solar power input.
The battery can be any 3.7V 1200mAh Li-ion battery. Motor can be any 3.7V DC motor. More Questions: Couple more questions, I cannot find a solar panel with those specs, do you think you could send me one on the internet so I can find something similar?
The inductor for the pocket solar LED light circuit consists of a small ferrite ring transformer having 20:20 turns which could be appropriately altered and optimized for enabling the most favorable voltage for the connected LED which may last even until the voltage has fallen below 1.2V.
