Friends:
How can one read error and/or warning code either via Sunny Portal or port
forwarding a Webbbox?
I can see charts galore on the Portal but I can’t find error or warning
logs.
Also, I get alerts via email but they are vague, as in “3xx” or “7xx”.
Apologies if this is a dumb question.

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 build
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 rains!
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 & w
Hello Wrenches,
Does anyone have suggestions for replacement inverters for the older
SunPower modules that require positive grounding?
Can anyone quantify what the efficiency drop may look like in a
transformerless inverter topology paired with these modules? Is it the
negative ground we want to
