Voltanic panels can be installed on homes, tinyhomes, motorhomes, campervans, boats, remote homes, tiny homes, summer houses, workshops, static caravans, stables and any outside building. You can mount them of your roof or on the ground.
Yes, all Voltanic panels will work with 12v battery systems. Note that our 400w panel has a high voltage so if you are thinking of buying this panel, you should use our MPPT controller for maximum yield. Contact us if you’re not sure and we’ll be happy to advise.
•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.
Inverter:Â The inverter converts the 12V from the battery into a voltage suitable for your house-hold appliances (230V).
To determine the number of solar panels you require, it is important to first understand the power requirements of your system. Please read our short blog post here which will help you determine how much power you need. Contact us if you need a hand.Â
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.

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
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
| 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) |
