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 is the difference between dusty and clean solar panel

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

two panels will cleaned (1 LG 1 Panasonic)

What Values say about cleaining solar panels

First period 25-28 August ( 4 days) solar panel was in standart conditions no cleaned. Power production shown below 2 LG panel and what they produced one by one..

For example left corner located LG 330 Wp produced 1,79 kWh energy at 25.08.2019
same day next to other LG in the corner produced 1,76 kWh energy

Weather was not always same during this test..

29.day of August I cleaned one LG and one Panasonic. The number changed ( you can see 5. Row at the table ) Negative numbers goes to positive this day.
