In this article and youtube video content show you , how effects cleaning on solar panels.. This is a real example done in İstanbul / Turkey and we have two different solar panel types. One type is LG Brand LG330N1C-A5 model 330 Wp 2 pcs solar panels. And the other type is Panasonic HIT VBHN325SJ47 model 325 Wp 2 pcs solar panels. I took all the values from the server of my solar inverter and arrange them into excel ( you will also see this values) and see how effects dusts on solar panel negative way.
What we did ?
We observed the values for four days ( all dusty) and the end of week we start cleaning ( only 2 ) . The last day we clean all the solar panels on the roof .
Realise this test at the end of august 2019 and we cleaned up 2 solar panels ( one LG one Panasonic) the other 2 remaining in dust
