Charger type

Solar Chargers

Solar-powered maintainers for vehicles parked without mains. Good for caravans, boats, and long-term storage.

Solar battery maintainers for cars and vans

Solar chargers use a photovoltaic panel to feed a small current into a 12V battery. They are not meant to fully recharge a flat battery in a short time; they are best used to maintain a battery when the vehicle is parked without access to mains power—e.g. on a driveway, in a marina, or on a campsite. In the UK, winter daylight and overcast weather limit output, so sizing the panel and regulator correctly is important.

Most units include a simple charge controller to prevent overcharging. Ensure the controller is suitable for your battery type (lead-acid, AGM, or lithium); some cheap kits are lead-acid only. For caravans and motorhomes with leisure batteries, larger solar setups are often used alongside the vehicle’s charging system.

  • Best for: vehicles parked without mains (driveway, storage, boat, caravan).
  • UK daylight limits output in winter; use as a maintainer, not a fast charger.
  • Always use a regulator/controller matched to your battery type.
