Poly 20W Solar Panel Kit 2

Poly 20W Solar Panel Kit 2 Description

Lightweight design with rigid anodised aluminium alloy frame and toughened glass

Designed in the UK. CE, TUV, ISO 9001 quality assurance.

Why Go Solar?

Beat energy inflation, energy security, remote location power sources (save a fortune on armoured cabling), mobile power sources, fast payback periods over conventional fuel sources such as diesel generation and hook-ups, keep batteries fully charged at all time as deep discharge shortens life, environmentally friendly power which reduces carbon emissions to slow global warming and climate change.

Applications

Sheds, Stables, Boats, Caravans, Motorhomes, electric fencing, road/ path/ driveway illuminated signage, campsites, yurts, multi-panel off grid power source for small buildings, remote telecoms, mobile food outlets, and many more…

Independent Off-Grid Solar Power Source

One or more solar panels can be connected a battery bank and power inverter using a solar charge controller. You can therefore have a 240v power supply anywhere in the world without grid supply. Please see our solar power kits.

Solar Panels do still generate power during cloudy and rainy weather

We have a rough guide below to solar panel power output relative to weather conditions:-

100% power output – clear sky midday sun with the panel fully tilted toward the sun's position in the sky.

75-85% output – clear sky midday sun but with the panel laid flat

50-65% output – thin cloud, or intermittent small clouds

10-20% output – midday overcast sky or rainy conditions

Technical Specifications

20w Poly-Crystalline Solar Panel with 1 metre cable

• Maximum Power (Pmax): 20W
• Maximum Power Voltage (VMP): 18V
• Maximum Power Current (IMP): 1.12A

In the event that the solar panel is in shade for a prolonged period, our solar panels either have one or two built-in bypass diodes which will enable the panel to continue generating.

Solar Panel Battery Charge Regulator Controller 12V / 24V Auto Switching

Solar charge controllers are required to regulate the power output from the solar panels to ensure effective charge of a typical 12V or 24V lead acid battery without overcharging.  Charge controllers also help to prevent reverse power discharge from the battery back into the solar panel at night as they act in the same way as a blocking diode.  PWM (Pulse Wave Modulation) solar charge controllers provide a cost-effective solution to linking your solar panel to the battery.  Optimised charge control helps to prolong the life of the battery. The LCD display shows gives an indication of battery charging state and battery voltage.  The display also indicates solar power input or power discharge from the battery.  Our charge controllers use an industrial grade micro-controller chip to work in a wide range of temperatures and humidity.
