Voltage measurement of the solar panel is very easy which is up to 5 volts.
Solar energy measurement system using arduino code.
Sir can give any suggestions regarding how i measure solar power by using arduino uno current sensor variable resistors and i also want to do solar tracking for that iam using stepper motor i dont know how to connect the circuit.
Voltage is measured by the help of a voltage divider circuit as the arduino analog pin input voltage is restricted to 5v i designed the voltage divider in such a way that the output voltage from it should be less than 5v my battery used for storing the power from the solar panel is rated 6v 5 5ah so i have to step down this 6 5v to a voltage lower than 5v.
Voltage sensor is used to measure a voltage of solar panel.
It is an on grid system so excessive energy is send back into the public network.
In this research four parameters that been measured are temperature light intensity voltage and current.
Block diagram of arduino based solar panel electrical parameters monitor.
As we know solar panels are dc power sources.
We started the process with the local energy supplier meralco to get registered for net metering.
I just have an idea that stepper motor is give to arduino solar panel connected to stepper motor for solar tracking next the solar panel power has to be measured.
In june 2015 we got our 1kw solar panel system installed.
Net metering means that we get paid for energy that we send back into the public network.
At the right side of the diagram is a solar panel which energy you want to measure.
This project aims to develop a measurement of solar energy using arduino board technology.
In this proposed system a solar panel is employed to keep monitoring the sunlight.
The aim of this solar energy measurement system project is to calculate solar cell factors through numerous sensor data acquisition.
But if we want to measure more than 5 volts then we have to use some additional circuitry like voltage divider.
