Rotating Solar Panel Using Arduino For Solar Efficiency

The solar panel is most efficient at a point called the maximum power point which is surprisingly not the maximum voltage 10v but a little less 8v.

Rotating solar panel using arduino for solar efficiency.

Rotating the panels to the east and west can help recapture these losses. A base penal frame super jack motors high efficiency solar panel arduino uno microcontroller relays rechargeable battery light dependent resistor ldr have been used for the system s. Also there would be no need for the wasteful voltage booster. In general with solar panels it is cheaper to use a bigger panel than to use clever tricks to get more from a smaller panel.

Here we use iot to send solar power boundaries over the web to iot worker. A solar panel in a fixed orientation between the dawn and sunset extremes will see a motion of 75 degrees on either side and thus according to the table above will lose 75 of the energy in the morning and evening. Multiply 8v by 0 650a and you get 5 2w. Use an arduino two small servo motors with light sensing photo resistors to steer a solar panel towards the sun.

Why not use 3 or 4 aa cells for a higher voltage that more nearly matches the solar panel. This motor is getting controlled by atmega328 microcontroller mounted on an arduino uno board which is in turn mounted on the pcb. And suppose if you want to measure up to 10 volts then you have to use the given circuitry. We use arduino based framework to screen a 10watt solar board boundaries.

Our framework continually screens the solar board and sends the power yield to iot framework over the web. Circuit diagram of arduino based digital voltmeter. This is called the short circuit current. When the panel provides its peak power the current draw is around 650ma.

Just connect the solar panel output voltage to analog pin of arduino and convert that in digital and display result on lcd or computer. For measuring voltage we have to follow the given formula. The battery will only pull down the solar panel voltage while.
