The capacity of the panel at 200w is normally more than adequate to top up a leisure battery system, while providing enough power to run a compressor fridge while the sun is shining. This is obviously a generalisation, as solar panels depend on solar light to create electricity. We can install panels of up to 250w if wanted and if demand is high.

Although solar panels are fantastic and we are big fans, they do rely on the weather, so for this reason we see solar panels as a nice addition to the right leisure battery system for your needs. It is pointless having a tiny leisure battery and a big solar panel if most of your power needs are to run lights and a heater at night.

Part of the solar panel system is the solar panel regulator. This controls the charge going into the battery and stops overcharging. It also stops reverse current flow and protects the panel. An MPPT regulator is the best way to do this and optimises charging.

Having a solar panel permanently on your roof is a real fit and forget item. Other than keeping it clean with the rest of your van, you can be safe in the knowledge it is doing its job of charging your batteries whenever you are parked up - be it on the drive, outside work or when away camping.
