Solar is a great alternative.

The 20W solar panel is a handy piece of equipment 

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.

How does the 20w solar panel work?

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.

Direct it to the sun and it operates.

The 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.

It is important to match the panel output with the controller you want to use.

If you want to use alternating current one will need an inverter to change direct current to ac. 

Will a 20-watt solar panel charge a battery?

If the sun shines 6 hours per day you will get 6 x 20 = 120 watts per day.

Provide for losses up to 15% and you get 120 X 85/100 = 102 watts.

Round the 2 and you get 100 watts per day.

If you have to charge a 48 amp hour car battery that drains to 50% you will need 12 x 48/2 = 576/2 = 288 watts.

The 20w solar panel will need three sunny days to charge a small car battery.

What can a 20w solar panel power?

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:

Caravan;

RVS;

Cars;

Boats;

Green House Solar Systems;

Marine;

Dry camp;

Water pumping systems;

Signaling systems;

Garden Watering;

Courtyard lighting;

Small household lighting system;

Street lighting;

Portable solar power;

Gate operators.

All small power electrical devices & small PV system;

Signaling systems and other off-grid applications.

Can I connect the 20w solar panel direct to a battery?

We cannot connect a battery direct to the solar panel.

We need a charge controller. It acts as a voltage regulator. This is to protect the batteries against overloading and surges.

Durable frame

• The panel comes with a Lightweight Anodized Aluminum Frame.


• The frame is durable and it can withstand high wind (2400Pa) and heavy snow loads (5400Pa).


• The frame is corrosion resistant and good for outdoor use for many years ahead.


• The frame is sturdy aluminum and it comes with 4 pre-drilled holes. The holes fit standard Z-brackets...Setting it up is easy.


• The aluminum frame has no sharp edges. You can use it hassle-free in and out any place that you need to.

Advantages

• The panel comes with Reinforced Safety and anti-reflection coated glass. The glass is 3.2mm thick.

• It uses a waterproof IP-65 rated junction box.


• The box provides complete protection against rough weather conditions.


• The 20w solar panel can still generate free renewable solar power on a cloudy day.

A disadvantage

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. 

To mention

• The manufacturer uses good quality solar cells.


• The 20w solar panel is well built and it comes in a convenient size.


• It can use packaging for protective storage when the panel is not in use.

Warranty

The 20w solar panel comes with a 5-year workshop warranty and a 20-year output warranty.

A100% money-back guarantee.

The basis for customer service and technical support is in California.

Conclusion

The 20w solar panel is well built. It is durable, sturdy, and easy to install.

When you buy it you get value for money.
