40 Watt Polycrystalline solar panel powering your home camper
cabin tool shed or any other building for that matter
Poly Solar Cells
High Efficient photoelectric conversion, stable performance
Unique etching process can increase the short-circuit current of
the solar cell
Advanced PECVD technology provides well-proportioned navy blue
silicon nitride anti-reflection velum:
Screen priting patterns are accurate and smoothness of the
electrode is improved thus making the cell
easier for welding and laser cutting

The top ten uses for solar panels include
> heat for your home
> power pumps
> indoor and out door light battery charging which can be a
beneficial if you have a reserve battery bank
that is charged through the day while sunlight is present and is
used through the nighttime hours. It can also
be used for simple solar panels to collect sunlight and convert it
into electricity.
> powering your home, camper, cabin, tool shed, or any other
building for that matter.
> when heating swimming pools, a solar hot water heating system
utilizes the solar hot water heating
panels, that can be mounted on your roof to collect the sun’s heat
and then is circulated to the pool.
> Solar panels are also being used in space exploration and
other forms of transportation.
