PRE-INSTALLATION
LOCATION AND BASE SUGGESTIONS
Below grade engineering is the responsibility of the purchaser.
Choose a location that has clear unobstructed views to the south (in the
northern hemisphere), in order to maximize the amount of irradiance
(energy) the PV panel will absorb. To determine the best angle of
incidence for the PV panel, use the solar angle calculator availabe at
www.solarelectricityhandbook.com/solar-angle-calculator.html
Prepare pole S1 by inserting threaded rods through pre-drilled hole at
bottom of pole. These rods will provide extra stability and retention within
the cement poured in the next step. Do not remove top wrapping (S1)
until pole is set in concrete for 24 hours.
Ensure all service locates have been completed including, but not limited
to, gas, water, telecommunications, and power. The base pole must be set
in 3200 PSI cement in a minimum 12" round (for 14' model) or 18" (for 20'
model) SONO tube or equivalent that is 4' below grade level. The easiest
method to hold the pole in place (brace) is to purchase (2) 8' - 2" x ½" pine
boards, place one board on the ground, place the S1 pole section on the
board at 90 degrees to the board 12" from the bottom edge of the board
to the top of the pole S1 (not to the top of the collar, to the top of the
pole), place the second board on top of the pole and aligned with the first
board underneath. Clamp both ends with C clamps.

Ensure soil is undisturbed 12" below grade. Dig hole accordingly, set
SONO tube, ensure the SONO tube is backfilled and compacted, pour
cement 2" below grade, place pole section 1 (S1) in the centre of the
SONO tube with 12” of the pole above grade. Ensure the pole section is
at 180 degrees to horizontal.
