HOW SUNPOWER®SOLAR PANELS WORK
CONVERTING SUNLIGHT INTO ELECTRICITY
SunPower solar panel’s unique design are designed and built for higher efficiency,
allowing them to convert the maximum amount of available sunlight into electricity. Though
they are effectively maintenance free, SunPower recommends you take certain precautions
to keep the system operating at its optimal level.
SHADING
· SunPower panels should be shade free: trees, plants, or other obstructions – including
rooftop antennas or satellite dishes, should be removed if possible.
· If necessary, safely trim any vegetation that might shade the panels during
daylight hours.
GENERAL SAFETY PRECAUTIONS AND CLEANING
· Our solar panels do not generally require cleaning to meet your system’sannual energy
expectations. Seasonal rains are usually enough to adequately clear any soil or dust that
might accumulate. When your SunPower Partner designed your system, they took into
account the typical soil accumulation for your area.
· If excessive soiling occurrs, or if you would like to try improving annual system output
beyond what is typically expected, you can clean your panels by spraying them from the
ground with a standard garden hose. Only spray the panels early in the morning or late
in the evening when the sun is very low on the horizon or not directly visible at all. Avoid
spraying the panels when the sun is at its peak and allow the panels to cool before
spraying them. Spraying cold water on a hot panel could result in panel damage,
voiding the product warranty. Tomaximize the energy improvement from cleaning, try
performing it during the summer months and in between natural rainfall cycles.
Alternatively you could get professional solar panel cleaners to address the soiling issue
- contact your SunPower partener to advice.
· Do not use abrasive cleaners or anything that could scratch the surface of the panels.
Many SunPower Partners offer professional panel cleaning services, talk to your
SunPower Partner to see if this is a service they offer.
·It’s not necessary to go onto your roof for panel cleaning or inspection and we strongly
recommend you not do so. If you choose to go on your roof, please take all safety
precautions and do not touch or disturb the panels or wiring. It is important to remember that
only a SunPower Authorized Partner should repair or touch system components. Please
remind anyone going on your roof that they should not disturb the panels or wiring.
· Do not use mirrors or any other objects to concentrate sunlight on panels. Doing so will
void your warranty.
