THE SMART CHOICE

This smart solar solution generates power from both the front and back, making the most of sunlight, even the light that reflects off the ground.

Perfect for floor or adjustable mounting systems where you can really take advantage of that extra energy.

CHARGE FASTER

Voltanic rigid panels are designed with the latest TOPCon N-Type tech to give you more power from the same sunlight, so your batteries charge faster, even when the light isn’t perfect.

Unlike traditional P-type cells, N-type silicon moves electricity more easily, meaning less energy gets stuck or wasted.

Each cell has an ultra-thin tunnel layer — about 10,000 times thinner than a human hair — plus a retention layer to cut down energy loss. This means more sunlight turns into real power, even on cloudy days or early and late in the day.

RELIABLE IN LOW LIGHT

Thanks to advanced N-Type TOPCon cells, Voltanics panels can still produce energy even when the sun isn’t shining brightly, like on cloudy days, in the early morning, or late afternoon. So you get more power throughout the day, no matter the weather.

WHAT MAKES N-TYPE SOLAR CELLS BETTER?

EASY TO INSTALL

Pre-drilled mounting holes to fit a variety of mounting systems, along with MC4 connectors for easy wiring and a strong, built-to-last design.

MORE POWER GENERATION

With 16-busbar (16BB) technology, Voltanics panels deliver improved energy efficiency and reduce microcrack risks, ensuring longer lifespan and consistent performance.

READY FOR THE OUTDOORS

Optimal performance in heavy rain, dust, and all weather conditions for a long-lasting solar setup.

WARRANTY-BACKED & CERTIFIED

With Voltanic, beauty and efficiency aren’t just a first impression; they’re a lasting commitment. A robust warranty backs every panel, ensuring that even after 30 years, your panels will still be generating energy.

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.

Real World Comparison:

100W Panel Performance

Watts = Volts x Amps

Controller	Standard PWM	Voltanic MPPT
Panel Voltage	20V	20V
Controller Charging Voltage	12V (PWM reduces voltage)	12V (MPPT reduces voltage)
Amperage	5.8A (amps stays same)	8.2A (MPPT increases amps)
Power Output	12V × 5.8A = 70W	12V × 8.2A = 98W
Power Wastage	~30W (lost as heat)	~2W (conversion loss)
