FAQ

 To figure out how many solar panels you need to charge your 12V battery, it really depends on how big your battery is and the size of the solar panels. In general, if you have a bigger battery, you’ll need more solar panels to charge it up. And if you have bigger solar panels, they’ll generate more power to charge your battery.

A 12V solar panel kit can power a wide range of appliances, including lights, smartphone, small electronics, and even some larger appliances like refrigerators and televisions. However, it’s important to choose the right kit size for your specific energy needs.

 Yes, all Voltanic solar panel kits are designed to be DIY-friendly and come with easy-to-follow installation instructions. However, it’s important to have a basic understanding of electrical wiring and safety precautions before attempting to install a solar panel kit.

A 12V solar panel kit works by converting sunlight into electricity. The solar panels in the kit absorb the sunlight and convert it into direct current (DC) electricity, which is then sent to a charge controller. The charge controller regulates the voltage and current to ensure that the battery is not overcharged or undercharged. The battery stores the electricity until it is needed, and the inverter converts the DC electricity into alternating current (AC) that can be used to power appliances.

Most solar kits have a dirty little secret they don't tell you about:
They waste valuable power.
Here's the deal

12V solar panels actually output around 20V

12V leisure batteries charge at just over 12V*

Standard PWM controllers simply drop those extra 8V — throwing away precious power

In cloudy Britain where every watt counts, this is a problem.
The Voltanic Difference

Every Voltanic Kit takes those wasted volts and converts them into extra amps using Advanced MPPT (Maximum Power Point Tracking) Technology.

Harvest 100% of your Solar Energy - No wasted watts

Charge your Batteries 30% Faster

More Power, Fewer Panels - Perfect for tight spaces

Better Value Investment - Get what you pay for

Maximum Power. Zero Waste.
