The 20W solar panel comes with high module conversion efficiency. You can use it for various 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.
Acopower manufactures the 20w module. Acopower is a
respectable company and known for its excellent after-sales service.
This is a 12-volt Monocrystalline solar panel and meant for residential purposes.
The panel comes prewired to a rear-mounted junction box that is weather sealed. It has power wiring pigtails. The length of the pigtail is enough for most applications.
The size of the panel is 295 X 290 X 20mm (11.6 X 11.4 X 0.8inches)
The manufacturing of the panel takes place in the United States.

The ACOPOWER 20w solar panel is for 12-volt battery charging and more. It is ready to supply cheap electricity. It is easy to set up.
it to the sun and it operates.
panel produces DC voltage. To use it for residential purposes you need a charge
controller. It acts as a voltage regulator. This is to protect the batteries
against overloading and surges.
is important to match the panel output with the controller you want to use.
you want to use alternating current one will need an inverter to change direct
current to ac.
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;
Small household lighting system;
Portable solar power;
All small power electrical devices & small PV system;
Signaling systems and other off-grid applications.
The only maintenance that you as a user have to do is making sure the cables are not damaged.
This is to ensure a good working condition.
Cleaning the surface of the a solar panel 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.
A dirty panel leads to a big drop in efficiency.
A professional person must perform all other maintenance functions.
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 comes with a 5-year workshop warranty and a 20-year output warranty.
basis for customer service and technical support is in California.
The 20w solar panel is well built. It is durable, sturdy, and easy to install.
When you buy it you get value for money.
