The 40 watt solar module comes with a suitcase-style design.

It has a strong handle and you can fold up the panel to carry or transport it like a suitcase.

It comes pre-wired for 12-volt battery charging. 

The 40 watt solar panel kit exists of 2 X 20 Watt solar modules, a 3 Amp charge controller and a solar panel handbag. Also a pair of pre-installed 10 feet solar cables, one pair 30 Ampere alligator clips. It comes with an aluminum stand that is adjustable. As well as a handle and latches.  

The portable solar module is 1.38 inches thick and has a size of 22 X 43.3 inches when open and 14.5 X 20.6 inches when folded.  

The module weighs 4.6kgs (10.15lbs)

It comes with a superb warranty for up to 25 years.

On a sunny day with 7 hours of sunlight in mid-summer, you can bargain for the generation of about 230 watts.

That is 7 x 40 watt = 280 watt. 

Now you allow for a loss of 15% and you get 280 X 85/100 = 238 Watt. 

Ignore the 8 and you get a fair 230 Watt. 

How to operate the 40 watt solar panel

Locate a sunlit area. Now it is a matter of unfolding the two panels and facing it towards the sun. It will immediately start producing an output. 

Be sure it is a spot without any obstacles blocking the sun.  

It is best to adjust the solar panels to realize max sunlight for as long as possible during the day. That will ensure the most power output.  

Remember you first connect the battery to the charge controller. Now you connect the load and finally the solar module.  

When disconnecting you do it the other way round. First, you disconnect the module, then the load and then the battery.  

Always connect the positive and negative leads according to the prescribed polarity. 

Read all safety precautions before you put the 40 watt solar panel into operation.  

Be very careful and aware of sharp objects that can damage the surface of the solar modules.  

A proper battery clip connection will prevent short circuits.  

Be aware that anything that covers the surface of the 40 watt solar panel can reduce the output power.
