The AKT-20-M AKT solar panel is a great panel for people with motor homes, caravans or boats trying to find an inexpensive and easy way to power their appliances or to charge their 12-volt batteries.

This 12 volt, the 20-watt solar panel is additionally waterproof and sealed against the elements making it ideal to be used in the garden to supply free solar power to power garden lights, pond pumps, as well as garden sheds and log cabin lights not connected to the utility grid.

What makes the 20W AKT solar panel good for home use is that it's made using thirty-six long-lasting, high-efficiency, monocrystalline photovoltaic cells designed to provide 20 watts of free solar power over a twenty-five years period. Additionally, this 20W AKT solar panel comes complete with its waterproof association box and 1.8m of flexible cable permitting you to connect it with other solar panels to form higher voltage systems.

This panel is one of AKT Solar’s vary of finest solar panels offered which challenges the current solar market by bringing a number of the highest solar panel efficiencies in the marketplace, all at reasonable costs.

This voltage optimized 20-watt solar panel is good to be used in 12V off-grid systems and charging 12V batteries. It’s rigid anodized Al frame and toughened tempered glass prevent harm because of frost, snow, hail and high winds giving it a design life of over twenty years of consistent free power.

The 20W AKT solar panel can be fitted with a bypass diode making it good for placing in series with different panels to form higher voltage systems. However, as standard, it doesn't have a blocking diode fitted and then shouldn't be left connected to a battery overnight because it will permit charge to escape from your battery.
