Suppose you are using 200 units on your general needs per month. You buy an electric car of 40 KWh that runs 300 Km from a full charge. That will consume 400 units more. So your monthly consumption would be 600 units.
Using a 5kW Solar system with a net metering connection you can recover the investment within 3 – 4 years. After 4 years you can enjoy free electricity for home use and car.
Solar car battery chargers have swept the market since it was introduced. They’ve been selling like pancakes and everyone seems to want one for their cars- and for a good reason.
Roof-mounted PV panels that are perfect for roofs of RVs. These roof-mounted solar car battery chargers are ideal for motor-hoes, trailers and caravans to keep the auxiliary battery charged.
How does it connect to your battery? There are types that run a wire from the PV panel and it goes conveniently directly into the cigarette lighter power socket. Other types have wires that are directly connected to the battery.
Battery regulators are not a requirement for solar car battery chargers. The PV panel’s wattage produces a small amount of current, thus it cannot overcharge your battery. Larger solar panels, like those that are mounted on the roof, needs a charge controller just to make sure that the battery does not get damaged from too much sun.
Of course, that also goes to say that if you live in areas that does not get too much sun, it’s not a very good idea to get your vehicle a solar-powered battery charger. For this particular issue, regular powered car battery will still do the job better.
If you have your car parked in the open everyday, then a solar powered car charger is a must for you. It can utilize the available sunshine to trickle-charge your car’s battery.
