The 20w solar panel comes with high module conversion efficiency. Utilize for a large number of minor off-grid applications to generate free electricity.
It comes with a module efficiency of 10.8%. The 20W Monocrystalline solar panel provides up to 20W power.
The solar modules are compact and a breeze to set up.
The 20w module is from Acopower. Acopower delivers high quality after sales service.
It is a 12-volt Mono solar module.
It comes with a junction box that is rear-mounted and it is waterproof.
It also comes with power wiring leads. The length of the pigtail is enough for most applications.
They manufacture the panels in the U S A.

The ACOPOWER 20w solar panel charges smaller batteries and more low amp functions.
It will operate as soon as you direct
it to the sun.
The output is DC voltage. For battery charging you do require controller to regulate volts.
Take care to match the panel output with the charger.
you want to use alternating current one needs an inverter.
To make the 20 watt solar panels fully operational we need a charge controller and battery.
Size the charge controller by dividing max watts per hour by total volts.
This is 20/12 = 1.7 Ampere
Add 25% for safety and you get 1.7X 1.25 = a 2.125 Amp charge controller.
Size the battery by dividing the total watt by volts.
This is 20 watt x 6 hours sunlight ( Depending on your area.) X .85 for losses/ 12 volt x 2 for DOD.(Depth of discharge.)
This is 20 x 6 x .85 / 12 x 2 = 17 Amp Hours .
A 20 Ah battery will be a good choice.
This solar panel is powerful and portable enough to be used to power hundreds of devices that you may use in a shed, boat or caravan such as lights and pumps.
Use it for off-grid solar panel 12V systems.
Use it for:
Green House Solar Systems;
Water pumping systems;
Portable solar systems;
systems and more.
Be certain the cables are undamaged.
Cleaning the surface is also very important.
Use a damp cloth to perform this duty.
If necessary you can buy a proper solar cleaning liquid.
You can also buy a a convenient solar brush for cleaning the surface of the panel.
Dirty panels cause drop in efficiency.
Allow a professional person to do other maintenance.
The 20w solar panel works well, but it would be better if the panel had a blocking diode. This is to prevent back-feeding when the sun is not shining.
The 20w solar panel has five years of workshop plus a 20-year output warranty.
basis for after sale support is in California.
The 20w solar panel comes as well built. It is durable, sturdy, and easy to install.
When you buy it you get value for money.
