Under normal conditions, a PV module is likely to experience conditions that produce higher current and/or
voltage than reported at standard test conditions. Accordingly, the values of I

and V

module should be multiplied by a factor of 1.25 at least when determining component voltage ratings, conductor
current ratings, and size of controls (e.g. inverter) connected to the PV output.

Photovoltaic (electric) systems operate automatically and require very little day-to-day supervision. The solar
array generates DC electricity whenever light falls on it similarly the inverter automatically turns ON as soon as
there is sufficient energy from the solar array to efficiently convert this into grid quality AC power.

Caution:
注意：
The module is rated to operate at potentially lethal DC voltages which have the potential can cause severe
electrical shock, arcing and fire hazards. Whilst some solar modules, manufactured by Sunpro Power, are
certified to operate up to 1500V always check the module label to confirm the actual rating of your product before
making connections.

To ensure proper system operation the correct cable connection polarity (Figures 1 & 2) should be observed
when connecting the modules to each other or to a load, such as inverter, a battery etc. If modules were not
connected correctly, the bypass diodes could be destroyed. PV modules can be wired in series to increase
voltage. A series connection is made when the wire from the positive terminal of one module is connected to the
negative terminal of the next module. A parallel connection is made when the wire from the positive terminal of
