“Z” brackets are the most common way to attach panels to various types of roofs. They ensure a secure attachment of your panel to the surface.

ABS mounts are mostly used on motorhomes, campervans, and caravans. These are ideal because they’re glued in place, so you don’t need to worry about drilling leaking holes into the roof.

For this kit, you should connect your solar panels in series.

Voltanic panels can be installed on homes, tinyhomes, motorhomes, campervans, boats, remote homes, summer houses, workshops, static caravans, stables and any outside building that you can think of. You can mount them on your roof or on the ground.

•70-80% Output – Clear sky midday sun but with the panel laid flat.
•50-65% Output – Thin cloud, or intermittent small clouds.
•10-20% Output – Overcast sky or rainy conditions.

Yes, this kits will work with 12v battery system. 

To determine the size of your kit, it is important to first understand the power requirements of your system. Please read our short blog post here which will help you determine what size kit you require. If in doubt, give us a message and we’ll be happy to help. 

Solar panels rarely achieve their rated wattage in real-world conditions. Optimal performance requires 25°C temperature, peak sunlight, no obstructions, and perfect panel angle – conditions met simultaneously. Environmental factors typically reduce output. For practical estimates, 75% of rated wattage per peak sun hour is generally reasonable in most climates.

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.
