3 Ways To Calculate The Actual Power of Solar Street Light

The application of solar powered street lamps is becoming increasingly widespread and popular to meet the requirement of green and sustainable development. 

However, some users often complain that they don’t know the actual power of solar street lights exactly. To solve this problem, Amber Lighting will next offer three ways to calculate the actual power of solar street lights.

Before introducing the calculation methods, we have to point out that the actual power of the solar street light is always changing. Therefore, only a rough actual power can be calculated no matter which method is employed, which is basically equivalent to the average power of the solar street light at high light hours, and therefore, this value is also very indicative.

1. Clamp ammeter measurement method
If you happen to have a set of programming remote control that matches the solar street light controller, you can know the actual power of the solar street light bu reading the parameters. But the end-user generally has no programmer, so the DC clamp ammeter can be equipped.

The test procedure is as follows:
●Charge the battery to full capacity;
●Disconnect the charging cable and enter the discharge mode;
●Test the line end of the controller connected to the light source;
●Test voltage and current;
●Calculate the actual power of solar street light.

The clamp ammeter measurement method is the simple and straightforward method as well as the most recommended method to calculate the actual power of solar street lights. If you are patient, measure the actual power every hour, which will enable you to figure out the way the solar street light manufacturers set the power of solar street light.
