6 FAQs about [Solar panel power supply circuit]
How does a solar cell power supply work?
This solar cell power supply circuit is made up of an oscillator transistor as well as a regulator transistor. The solar panel charges the battery when sunlight is bright enough to generate a voltage above 1.9v. A diode is necessary between the panel and also the battery as it leaks about 1mA from the battery when it really is not illuminated.
Can a battery draw power from a solar power supply?
Therefore any battery or load circuit that needs a voltage between 1.1V to 10.4V can draw power from this circuit. As this solar power supply provides maximum 681mA current, any battery or circuit which takes the maximum current of 681mA can be connected to it.
What is regulated solar power supply?
The regulated solar power supply designed in this project provides regulated and adjustable voltage from 1.1V to 10.4V by varying the potentiometer RV1. Therefore any battery or load circuit that needs a voltage between 1.1V to 10.4V can draw power from this circuit.
What is a solar panel battery charging circuit?
This circuit makes sure that the voltage from the solar panel never exceeds the safe value required by the battery for charging. Normally to get optimum results from the solar panel, the minimum voltage output from the panel should be higher than the required battery charging voltage.
Can a solar panel be used for AC & DC load?
The PV panel wiring can be used for both AC and DC loads. AC load can be powered by UPS/Inverter, using the storage energy in the battery as backup power. It can also be used without the battery if you don’t need the backup (stored) power later at night or shading. This way, the solar panels will direct power up to the AC load via Online UPS.
What is the voltage of the solar panel in the diagram?
The following solar panel wiring diagram shows that an 120W, 12V solar panel is directly connected to the 12V charge controller. Battery and inverter are connected to the battery terminals (Positive & Negative) of the charge controller. DC load is also connected to the DC output terminal of the charge controller.
