The sun is a near-unlimited source of free electricity, which makes the idea of using a solar car battery charger so tempting. If you need to charge your car''s battery, one of these clever solar panels on your dashboard can supplement battery life, preventing a flat battery.
This idea used to be reserved for particularly eco-minded vehicles, but now there are a raft of aftermarket examples available. These inexpensive slabs of cells will happily sit on a car''s dashboard or rest on the bonnet collecting energy from the sun to provide some extra electricity for a car''s battery.
They work similarly to a trickle charger, albeit without needing a socket to plug the device into. They''re great for driveway-parked cars that aren''t driven often and are at risk of a flat battery without some extra support.
Black Friday is over, but that doesn''t mean you can''t find a great deal for some last-minute Christmas shopping. For those that might have missed the massive sale event that ran from 21 November through to 2 December, there''s still time to save on solar car batteries. Check out some of the top deals that are still live below:
Yes, solar car battery chargers do work, but their effectiveness depends on a few factors, including the quality of the charger, the size and condition of the battery, and the amount of sunlight available.
That will depend on a number of factors, including budget, type of use (such as maintaining a charge versus recharging a depleted battery), the size of the car battery, and the amount of sunlight available in your area. Popular choices often include brands like Battery Tender, NOCO, and Sunway Solar, which offer a range of products to suit different needs and budgets. The AA 12 V Car Solar Battery Trickle Charger, which is our Editor''s choice, is a pretty good all-rounder at a decent price.
Theoretically, it is possible to overcharge a car battery with a solar charger if the charger does not have a built-in charge controller or overcharge protection. The majority of good solar chargers typically include a charge controller to regulate the charging process and prevent overcharging. This ensures the battery remains at an optimal charge level, protecting it from damage and extending its lifespan. Always go for a charger with overcharge protection to avoid battery damage.

The approaching winter means that anyone lucky enough to have a ''fun'' car for the warmer months will be thinking about tucking it up in storage until spring. Many others will find that the colder weather will kill weaker car batteries in little-used cars.
Which is where a solar maintainer could come in handy. These are not designed to charge a flat battery but should help with the natural discharging and power used by alarms, dash cams and clocks. So which of these six solutions is the one to keep your car battery topped up?
We tested the effectiveness of the panels by attaching them to multimeters and measuring the output in natural sunlight, both when sunny and with overcast skies. We also checked the conditioners would not overcharge a battery or take power out of it in darkness.
Points were also given for panels that were easy to use inside a car or offered weather protection if designed to be operated outside the vehicle, such as on a garage roof or wall. Other features such as USB ports and a choice of power connectors were also rewarded.
For a start, it had an output that put some supposedly more powerful panels in the shade too. It''s supplied with a choice of clips or a 12V lighter socket and a long 3m cable, which plugs into the twin solar panels. When not in use, these fold into a tiny 230 x 198mm canvas package that will easily fit in a glovebox or seat pocket.
Designed to survive outside, it comes with a 5m-long cable – making it perfect for placing on the roof of a garage and feeding into a car inside. A USB socket means that it can also be used to charge a tracker or other device while you''re off camping, too.
