The Benefits Of Using Solar Panels To Charge Electric Cars

For anyone who owns an electric vehicle (EVs), or those considering the shift away from traditional petrol and diesel cars, the financial benefits of integrating solar panels and battery storage systems are compelling.

Beyond the environmental incentives, this combination presents an incredible opportunity to significantly reduce household energy costs, enhance energy independence, and secure a return on investment over time. In this article, we’ll delve into how using solar panels to charge electric cars not only paves the way for sustainable living, but can save you money in the long run.

Reduced Fuel and Energy Bills

Switching to an electric vehicle already offers savings on fuel costs compared to conventional vehicles, given the lower cost of electricity compared to petrol or diesel. When you add solar panels into the mix, the savings amplify. Solar panels generate electricity that can directly power your home and charge your EV, drastically reducing your electricity bills. Over time, the savings from using solar panels to charge your car and power your home can offset the initial cost of installation.

Battery Storage: Maximising Your Solar Investment

Battery storage systems store excess solar energy for use during periods of low sunlight or high electricity demand. This capability, alongside smart energy management systems such as the Tesla Gateway, means you can take full advantage of off peak tariffs, such as Economy 7. The benefit of this is that you can reduce the amount of electricity you buy from the grid when prices are at their peak, leading to further reductions in your energy bills. The energy you have stored in your batteries can also ensure that your EV is charged overnight using solar power generated during the day, maximising the use of free solar energy and minimising reliance on the grid.

Smart Export Guarantee

For times when your solar panels produce more electricity than you can use or store, the UK’s Smart Export Guarantee (SEG) scheme becomes particularly beneficial. This scheme compensates households for surplus energy fed back into the national grid, further offsetting your energy bills.

Enhanced Energy Independence and Stability

The combination of electric vehicles, solar panels and battery storage systems grants households a remarkable level of energy independence, reducing vulnerability to energy price volatility and grid outages. By generating and storing your own electricity, and using that to fuel your car, you’re less impacted by rising fuel and electricity prices. This provides peace of mind, ensuring you have more predictable and stable costs over time.

Environmental Benefits

Whilst the primary focus of this article is financial savings, it’s impossible to overlook the environmental benefits. Charging your EV with solar energy and reducing reliance on the grid means lower carbon emissions and a smaller environmental footprint. This transition supports the UK’s broader environmental goals, including the commitment to net-zero carbon emissions by 2050.
