Usually the load of the modules is a group of batteries. To prevent the modules from
being charged by batteries under the circumstance of no sunlight, it is important to add a
shut-off diode in series. Also, please consider the voltage decrease of PN junction of
about 0.7V when connecting the shut-off diode. The modules can withstand for a
maximum positive or negative design loading of 45 lbs / ft
The environmental temperature may also affect the modules' output power. If the
environmental temperature goes up, the short-circuit current will increase a little, while
open-circuit voltage will decrease, which will result in a decrease in the module's output
power. Therefore, a lower environmental temperature is most appropriate for the module.
5. Operation and Maintenance
ET Solar module users should rinse the array seasonally or as needed in dry, dirty areas
to improve the performance of their solar electrical systems. Heavily soiled modules will
have a decrease in performance due to reduced light on the photovoltaic cells. Studies by
the PVUSA in Davis, CA estimate that during a dry year module soiling may affect
performance by as much as 7% annually with no cleaning. Seasonal rains often clean the
modules, however, during the long dry summer, it is helpful to rinse the modules as
needed.
ET solar modules may be rinsed with clean water to remove dirt. Normal pressure from a
standard residential hose and nozzle is recommended. Early morning and late afternoons
are favorable times to clean to avoid a sudden change in temperature. Care must be taken
since modules produce energy any time light is present. Modules are not to be touched or
walked on except by a licensed professional.
