Installing Solar Panel SOLAR33
Solar Panel SOLAR33 is a custom-designed module incorporating high-
power efficiency and quality. The 33 W panel contains 36 polycrystalline
silicon cells. The SOLAR33 modules are lightweight and have high
power and a robust construction.
The cells are protected from dirt, moisture and mechanical impact using a
tempered, low-iron glass front. The solar circuit is laminated using EVA
(Ethylene Vinyl Acetate) between tempered glass and a durable, multi-
layered polymer back sheet for superior moisture resistance.
WARNING Photovoltaic modules generate direct current (DC) when exposed to
sunlight or other sources of light. Although single modules produce low
voltage and current, shocks and burns can still result from contact with
module output wiring.
CAUTION Handle the solar panel with care: impact on the front or rear surface can
damage the module. Do not bend the panel.
CAUTION When working with the panel, use properly insulated tools and wear
rubber gloves.
NOTE The rays of the sun should be perpendicular to the panel. In other words,
sunlight should hit the panel at a 90° angle.
NOTE Do not concentrate light on the panel in an attempt to increase its power
output.
