The 5W solar panel is handy to generate electricity for small appliances. Utilize it for many small away from the grid applications.

Acopower is the manufacturer of this 5W Monocrystalline Solar Panel. It is for smaller 12 volts off-grid battery charging.

The manufacturing  is happening in the United States.

39 Inch long Pigtail39 Inch long Pigtail.

The  junction box comes IP65 rated. They mount it in the rear and is pre-wired.

It comes with power wiring pigtails that they attach to the junction box.

The attached pigtails are 1M (39 inches) long.

It is necessary to buy mounting Z brackets and a charge controller.

If there is a need Acopower can manufacture customized cables.

How does the 5w solar panel work?

The 5w Monocrystalline module is for small 12-volt battery energizing and more. 

When the sun shines upon it it will be in operation.

The panel produces DC voltage and is only meant for small appliances.

For a six hour day in mid summer you will get 6 times 5 = 30 watt.

With a possible 15% loss you can get out 25 watt.


Sturdy Anodized Aluminum Frame.Sturdy Anodized Aluminum Frame.
  • The 5w solar panel comes with a lightweight and strong anodized aluminum frame.
  • This is good construction and built to last for many years.
  • To ease set up it comes with holes already punched for mounting. The holes  do fit standard Z-mounting brackets. To set it up is easy.
  • The panel can withstand snow loads up to 5400PA as well as high winds up to 2400PA.
  • The aluminum frame is safe to use. It does not have sharp edges that could cause damage.  It is safe to use when needed.


  • The 5w panel comes ready for connecting. It is small and setting up is hassle free.

  • Pre-drilled holes ensure fast and easy installation.

  • The module comes with no-reflection 3.2mm thick safety glass. It is  reinforced and low-iron tempered.
IP-65 Rated Junction Box.IP-65 Rated Junction Box.
  • The 5w solar panel comes with a waterproof IP-65 rated junction box.
  • The strong junction box protects against extreme weather.

  • These panels are cost-effective and the manufacturer provides free professional engineering services.


Some people feel it will be better if the manufacturer includes mounting hardware.

Mentioning some facts 

  • If you transport or install the 5w solar panel inappropriate you could damage it. That will possible void the warranty.

  • Construction is of high quality.

  • The panel produces well in low light conditions.


The module has a 5-year workmanship guarantee.

It also comes with a 25-years 85 percent output warranty.

It also comes with customer service as well as technical support based in California.

In conclusion

The 5w panel is very handy. It is solid and well-constructed.

The panels come with a very good warranty.

It is cost-effective and efficient.

The module delivers the rated voltage and current.
