How to charge your electric car with solar panels [UK, 2024]

As a rough average, it costs £14,500 to install a solar panel system and home charging point. First, you''ll typically need a 5.9kWp solar panel system, which usually costs around £11,500. If you add a solar battery, allowing you to store your solar electricity and use more of it to charge your car, the price tag rises by £2,000.

Can 18V Solar Panels Effectively Charge a 12V Battery? Exploring

Yes, an 18V solar panel can charge a 12V battery, but you''ll need a charge controller to regulate the charging process. Solar panels generate higher voltages than the batteries they charge, and without regulation, the voltage from the solar panel could overcharge and damage the battery.

What Is a Solar Charge Controller, and Do You Need It?

Off-grid solar panels (those rated at 17-18V) are required when using PWM controllers, which sometimes cost more than grid-tied panels (often rated at 37V). PWM controllers work best in "ideal" conditions — warm, sunny weather.

(If you don't need to understand the why's, scroll to the end for a simple flow chart).

What if solar panels were only rated at 12V?

Solar panels rarely output their full power rating due to clouds, dirt on the panels, or other environmental factors. So, if they were only rated at 12V, they would always be putting out less power — which a 12V battery cannot accept. A 12V battery at rest is around 12.7V, and a charging battery is around 13.6 to 14.4V.

Do small Solar panels need a charge controller?

Tiny solar setups are the only exception — 5-watt trickle chargers and similar devices will not need one. For example, many golf cart owners will keep their batteries charged over winter with a small panel. This setup does not need a charge controller between the panels and the golf cart batteries.

Can a cheap solar charge controller overcharge a battery?

Cheap controllers may not have the over-voltage battery protection which could result in the battery being overcharged with potential damage to the battery; caution is recommended. Normally, due to the increased circuitry, MPPT solar charge controllers will be physically larger than PWM solar charge controllers.
