Definitely heard stories and have seen a few insurance claims for cracked
glass.
I have had clients send me pictures of "solar" guys walking on the panels on
their roof.
I guess it is OK to do this if you change your business na

The volume of water in a Florida downpour can come on virtually instantly
and would be many many times more volume of water than a residential hose.
The rate of temperature change in a downpour will be many multiples of what
a hose could do. This happens almost daily in summer here. A few hose
I tell my clients to wash your panels like you’d wash your car. Similar soaps if needed to remove pollen or harder to remove things and softer bristle brushes help. Doing it during the heat of the day means a larger chance of mineral deposits vs cooler times depending on your water. Myself I don’t
I now live in a more rural part of California and the dust buildup and bird
droppings on my modules cuts energy production down by about 5% during the
dry months. I imagine that professional cleaning services would still cost
more than the recouped energy production, especially since the dirt
Jason,
This is the way thermal shock was explained to me. Thermal shock creates
micro fractures in the glass. PV modules have tough tempered glass so
one thermal shock event, or a few dozen events, is unlikely to cause a
module to fracture; but eventually the glass gets to the last straw when
I don't understand the thermal shock nonsense. It routinely starts
downpouring here when it's blazing hot out (sun showers) and the rain is
way cooler than ground water in summer. It makes no sense. If hose water
from the ground is going to hurt solar panels, you better not put them
where it
Hey ally 'all,
Ok bad solar installer! 7 years & I have never cleaned my modules & live on
a dirt road. Yeah rain does a good job with the dust but there is a film
mostly on the edges.
What does everyone do for cleaning?
My array is 16'+ tall on a hill side. I have a pressure washer &
15 matches
