The 40 Watt solar panel kit to be operating with a combination

40 Watt Panel

The 40 watt solar panel kit works with two portable polycrystalline solar  panels. This is to produce a required output.

They manufacture the  40 watt solar panel with a charge controller that is built-in. Use it as a battery charger or a solar generator. 

40 Watt Suitcase

Eco-Worthy manufactures this 40 watt portable polycrystalline solar module. 

Composed of a multi-crystal solar cell with efficiency of over 17%.

The 40 watt solar panel has a suitcase-style design with a strong handle. Fold it up and 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 and a pair of 30 Ampere alligator clips. It comes with an aluminum stand that is adjustable. As well as a handle and latches.  

There is a 25 year warranty.

In mid-summer, with 7 hours of sunshine per day, you can bargain for the generation of about 230 wattages.

It is 7 x 40 watt = 280 watts. 

Provide for 15% loss to get 280 X 85/100 = 238 Watt. 

Ignore the 8 and you have 230 Watt. 

How to operate the 40 watt solar panel

Locate a sunlit area. You unfold the two solar modules. Direct the surface at the sun and it will produce an output. 

Avoid a spot with obstacles that can block the sun.  

Adjust the solar panels for max sunlight during  day time. That ensures most power output.  

Remember when connecting;

First the battery to the charge controller, then the load and last the solar module.  

When disconnecting;

Do it the other way round. Module, then the load and last the battery.  

Always connect according to the prescribed polarity. Read the safety precautions, and then put the 40 watt solar module in operation.  

Be aware of sharp objects. It can damage the surface of the panel and cause reduced output..  

Avoid short circuits with proper battery clip connections.

Remember objects that cover the surface of the 40 watt module can reduce output.
