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: 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.
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.
