Measure Amount of Energy Collected by Solar Panels

Most solar panels that are to buy from memory with the amount of energy they can produce labeled. This label lists Panels peak performance and that means maximum watts, they can produce when it is fully exposed to sunlight. If the claims of solar-panel manufacturers, confirm or label is missing, you can output, to compete with the help of small experiment FIG.

If you. four power resistors, for example, values ​​for the different, 100, 50, 25, 3 ohms Calculate voltage over different resistances. Put numbers in the table.

Measure Amount of Energy Collected by Solar Panels

You need to measure current measured as voltage or resistor value , as well as power output measured as voltage x calculated current . For instance, if you draw table, you will make four columns–resistance, voltage, current, and power. Let us say you use 100 Ohms resistor, and you get voltage of 28.8 and 0.29 current.

power generated is 8.30 Watts. Similarly, if you use resistor of 25 Ohm, voltage and current produced will be 22.5 and 0.90 respectively. power produced in this case is 20.25 Watts. Plot graph of measured voltage and calculated current, keeping voltage on Y-axis from high to low and current on X-axis going left to right . Spot center of bend of curve.

This mid-point is operating point of panel, which means that solar panel collects its peak power and generates maximum output at this point. Multiply values of current and voltage at operating point. This will calculate each panel’s peak power.

We hope this information about “How to Measure Amount of Energy Collected by Solar Panels” is really helpful to you as well as other information related to Solar_Energy
