Discover the simple reasons your 5kW solar system output is too low.

To cut a long story short, solar panels don''t like to be hot. Most solar panels lose about 10% of their rated power on a 25°C day, more if it is hotter. Let''s assume 10% for this estimate. 3. Dirt (5%) When your solar panels are put on your roof, airborne particulates like dust will settle on the panels'' glass.

Solar system fault finding guide & solutions

To explain why partial shading is such a problem, you first need to have a basic understanding of how solar systems work - Solar panels are generally connected together in strings of 4 to 14 panels unless you have microinverters installed on each solar panel. The reason for this is that strings of panels generate a higher voltage, which is …
