Polycrystalline solar technology utilises solar cells that are manufactured from silicon. Producing a far more efficient and compact solar cell when compared to amorphous panels, while producing greater output power.

The Projecta range of Polycrystalline Solar Panels are constructed with heavy duty steel frames that will withstand wind speeds in excess of 130 km/h and are corrosion resistant. Featuring tempered low iron glass that provides better impact resistance and better light transmission. Allowing the generation of more electricity by reducing the quantity of light that is reflected away from the module.

Ensure you use a quality solar controller when connecting Projecta solar panels to a deep cycle battery. Connecting a solar panel directly to a battery without a solar controller will cause over charging of the battery as well as over discharging during night when the solar panel draws current from the battery.
