3. Solar Array Installation
WORKING AT HEIGHT IS DANGEROUS – PLEASE OBSERVE
ALL REASONABLE SAFETY PRECAUTIONS
 Record the direction of the solar array: ……………….. degrees.

Record the tilt angle of the solar array: ……………….. degrees.
 Check there is no possibility of shading between 7am and 5pm.

Check each solar module for mechanical damage.
 Record the serial number, open circuit voltage and short circuit current
for each solar module below:
Solar Module Serial Number Voc Isc
1
2
 Assemble the array frame and attach the solar modules. Check each
solar module is securely fixed.

Complete solar module interconnection wiring and connect solar cable.
Check that the connections are tight.
 Measure and record Voc of the solar array:
Voc =

Check that array Voc is similar to the Voc for individual modules

Measure and record Isc of the solar array:
Isc =
 Check that array Isc is similar to the sum of the Isc for the individual
modules
 Install the assembled solar array on the roof.

Route the solar cable to the refrigerator location and fix securely.

Install the array earthing as close to the solar array as possible,
ensuring the earth cable is installed at least 1.5m away from the solar
cable.
 Connect the earth cable to the array frame and to the earth rod then
secure the earth cable. The earth cable should follow the shortest and
straightest possible path between the frame and the rod.
