Dear Nusrat,

welcome!

I would like to add to Ashray that in order to get the output generated energy per one year, You have to access the pout maximum out power as a function of time.

It will be a table of one day. Then you will have 365 such tables.

You need to integrate power over the time by using a proper numerical integration method. Or you can firstly interpolate the readings and then making an integration on one day time. Then you sum over all days in the year.

The simplest solution is that can use the simple formula:

Ek/day= 1 hour (SUM pi from i=1 to i=24). The units will be in watt.hour,

To get in Kwh you need to divide the above numbe by 1000.

Then for one year

E/year = SUM Ek fro k=1 to k= 365

Best wishes

1. Interpolate the solar panel performance using the rate of degradation in excel

2. Export hourly internal data in excel

3. Plot both using excel.

Hope this helps !

You can do is a system that captures the data of the power delivered from the solar panel, this is as simple as using a module with a microSD to measure the data and save them, then read them on an excel sheet, on the other hand, the Solar panel efficiency depends on many factors, such as tilt of the solar panel, geographical location of the panel, and the time of year, the foregoing taking into account the summer and winter solstice.

There is no determined way to establish these efficiency measurements of a specific solar panel, since each panel is different because of its constitution and if there are even more tables by manufacturers, these vary according to the geographical location of the panel where it is located , if you want you can read this article that shows you a work done to do this operation:
