Ensure that the connectors are connected correctly.
INSTRUCTIONS FOR GROUNDING
The modules have to be grounded. Please observe the corresponding national regulations and standards. Due
to ASOL-250P-WSR modules are framed and do not have specified point of grounding it is necessary to
ground all installation system.
Use one of the fastening holes in the construction to ground the module.
Use a copper grounding conductor with a minimum diameter of 16 mm² (heat resistance 90 °C).
When fastening the grounding conductor use a tooth lock washer so that the anodized layer of the
construction is penetrated.
ELECTRICAL SPECIFICATIONS
The module electrical ratings are measured under Standard Test Conditions (STC) of 1 kW/m
2
irradiance with
an AM 1.5 spectrum, and cell temperature of 25. The detailed electrical and mechanical characteristics of
ASOL-250P-WSR crystalline silicon PV modules can be found in datasheet. Main electrical characteristics at
STC also appear on each module label. The maximum system voltage for all module series is 1000 V. Under
certain conditions, a module may produce more current or voltage than its Standard Test Conditions rated
power. Accordingly, when determining component ratings and capacities, the module short-circuit current at
STC should be multiplied by 1.25, and a correction factor should be applied for the open-circuit voltage.
An additional 1.25 multiplier for the short-circuit current (for a total of 1.56) for sizing conductors and fuses
may be applicable, depending on your local regulations

LOCATION SELECTION
The solar modules should be mounted in a location where they will receive maximum sunlight throughout the
year. Modules facing 30 degrees away from true South (or North) will lose approximately 10 to 15 percent of
their power output. If the module faces 60 degrees away from true South (or North), the power loss will be 20
to 30 per cent. When choosing a site, avoid trees, buildings or obstructions which could cast shadows on the
solar modules especially during the winter months when the arc of the sun is lowest over the horizon.
MODULE TILT ANGLE
Modules connected in series should be installed at same orientation and angle. Different orientation or angle
may cause loss of output power due to difference of amount of sunlight exposed to the module.
