Solar Panel Circuit

In this circuit the solar panel charges up a 3 cell nimh battery 3 6 v.

Solar panel circuit.

Using the solar light ic all you need is the solar ic an inductor and the ultra bright led to make the circuit. When you connect the positive terminal of one panel to the negative terminal of another panel you create a series connection. Ac electricity flows through every outlet of your home powering the appliances. A relay is introduced in the circuit and is wired with the led module such that it s switched on only during the night or when it s dark below threshold for the solar panel to generate the required any power.

Add the battery and the solar cell and you have a solar light. One positive and one negative. Between the two is a reverse blocking diode. This one way valve allows current to flow from the solar panel to the battery but does not allow current to flow backwards out of the battery through the solar panel.

Basically that is 1500w 12 18000wh. This circuit makes sure that the voltage from the solar panel never exceeds the safe value required by the battery for charging. In order to regulate the voltage from the solar panel normally a voltage regulator circuit is used in between the solar panel output and the battery input. Dc is then converted into alternating current ac through a device called an inverter.

When you connect two or more solar panels like this it becomes a pv source circuit. Solar light ics are very handy they have the dark detection circuit and the voltage multiplying led driver built into one small four pin component. Just like a battery solar panels have two terminals. I am not sure why you said 2pcs of 120ah12v battries in series.

The solar panel voltage specs may be anywhere between 18v and 24v.
