Charging An Electric Car Batteries With Solar Cells

Is it possible to charge the batteries of a Do It Yourself (DIY) electric car with solar cells?

As it turns out, you can.

However, you can’t mouth the solar cells on the car because there is simply not enough surface area. Well, unless you want to cover the entire car with Photovoltaic (PV) cells, that will be cool though, but still not enough.

The only way to utilize solar power on an EV is through a stationary solar array…preferably at your home.

If you are planning to charge to batteries with solar energy, look at your battery charger first.

How much current does it need?

A typical solar panel with 36 pieces of 3” x 6” solar cells is capable of generating 18 volts at approximately 75 watts of electricity. Is it compatible with the battery charger?

The solar array can easily be scaled up meaning you can add more solar panel to increase the current output from the solar cells.

There is a clear benefit of using solar energy to power a pure electric car…you have literally zero cost for driving the EV.

When you are using an EV, you’ve already saved a ton of money on gasoline. Your vehicle running cost is the electricity needed to charge the deep cycle batteries. And when you are using free energy from the sun, your electric car is literally off the power grid. A pure green vehicle!

Would it be difficult to build a DIY solar power system at home?

If a person can convert a gas guzzler to run on purely electricity, building a residential solar energy system is a piece of cake. The system is much simpler compared to an electric car conversion project. You have less components to worry about also.

How much does a home solar power system cost? I did some reading on this subject. The actual cost of the entire system is not very expensive.

A DIY solar panel can be built with a budget of less than $200. You can save a lot of money by sourcing for cheap or recycled solar cells. All you need to know is where to find them.

    Good info.. Maybe charging with solar cells will cut more cost for car user

    Hey, ok, I get it, I guess – but does this really work?

    Hi Harry,

    You can charge the batteries of an electric car by using power generated by solar cells. It does take some time though.

    Solar-charged electric car used for a couple hours a week for short trips in Arizona – perfect solution. Being driven daily for several hours in foggy, rainy northern climes, downtown highrise areas, at night, or in cold (where you would need electric heat) – not so good. It all depends on your location, needs, weather, driving habits…….

    I understand the idea of putting the cells on the car body and being at work all day and getting a decent trickle of meaningful charge. But putting them all over the garage roof then storing that power into a battering ro charge the battery when finally home may be pricey because it would approach the budget of solar panneling the house for home use. Farms used to have this little cheapy wind turbines I bet I could get some decent use in Chicago out of that.
