Charging EVs with solar

Fast read

To reduce our reliance on fossil fuels and reduce greenhouse gas emissions, we can use solar and other renewable energy to charge our electric vehicles.

If we were to charge with solar PV systems and batteries this would allow us to reduce our dependence on non-renewable energies like coal and gas and would slow down climate change.

For those wanting to change their ways of charging and want to use solar to charge their EV there are multiple ways in which this can be achieved.

The main and most popular way is through solar panels in your home or business. Alternatively, you can install community solar farms or even very large ones in remote areas and channel the power to public EV charging stations, allowing many drivers to shift towards a cleaner future.

Can I charge my electric vehicle with solar panels?

Solar energy and electric vehicles (EVs) represent a powerful alliance in our ongoing battle against climate change. These innovations are on the brink of reshaping the energy landscape, not just as isolated technologies but as interconnected solutions. Let’s explore why solar and EVs are destined to drive hand in hand into a more sustainable future, utilising solar power for charging EVs.

A natural partnership – the marriage of solar power and EVs

Both solar energy enthusiasts and electric vehicle advocates share a common mission: reducing our reliance on fossil fuels. Their growth is motivated by an increasingly urgent need to mitigate climate change. How do these two technological marvels align, and what’s the future they are forging together?

Charging EVs with solar power – a homeowner’s dream

The marriage of solar power with electric vehicles paints a compelling picture of a self-sufficient household. Imagine homeowners equipped with solar panels and storage batteries, generating energy to power both their homes and their EVs. This not only slashes energy costs but opens a doorway to energy independence, allowing a theoretical break away from the traditional grid.

In countries like Australia, current regulations are the only inhibiting factor for the ‘Vehicle-to-Grid’ systems concept. The infrastructure is there, but laws need to evolve to keep pace. The future promises a world where EVs can plug into a home’s power system, pulling electricity for charging and even sending some back. This would transform EVs into mobile energy storage units, offering support to the grid during peak times or outages.

Public EV charging – a grid facing stress?

Solar power has a critical role to play in public EV charging stations. Right now, if EVs are charged using coal-fired electricity, the environmental benefit is nullified. With the recent spike in EV adoption in places like Australia, the demand for sustainable charging solutions is acute.

Consider this: A large fridge uses about 500kWh of electricity a year. An average EV driving 12,000 km per year uses 1800 kWh. Two such vehicles in a household consume 3600 kWh, equivalent to the energy consumption of 7.2 large fridges running all year. Therefore you can appreciate scaling EV charging up across Australia will create a substantial strain on the grid.

Solar-powered charging stations

Responding to this demand, the number of solar-powered charging stations has surged. These stations offer a two-fold solution:

  1. Addressing Solar’s Intermittency: By collecting and storing solar energy, they ensure that EVs can be charged sustainably even when the sun is down.
  2. Preventing Grid Stress: Distributing the load during peak times, solar energy storage facilities mitigate the pressure on the grid caused by simultaneous EV charging.

Why only go solar and battery when you go for an EV as well?

Utilising solar to charge EVs comes with a wealth of benefits:

  • Cost Savings: With a potential savings of around $2000 per year, solar can offset the entire cost of charging an EV.
  • Environmental Impact: By cutting down on fossil fuels, solar charging reduces greenhouse gas emissions, aids in climate change mitigation, and decreases noise pollution near major roads.
  • Energy Independence: In areas with an unreliable grid, generating your own electricity to charge your EV can be a game-changer.

A glimpse into the future

As technology evolves and the prices of solar panels and EV batteries continue to drop, more consumers are ready to jump on board. Over the next decade, we can expect to see combustion engine cars giving way to EVs, hopefully powered by renewable sources.


Solar energy and EVs are more than complementary technologies; they are partners in forging a cleaner, more efficient world. Together, they offer us a chance to break free from the shackles of fossil fuels and high fuel costs. Steering us towards a more sustainable and environmentally friendly transportation system. The brilliant fusion of solar power and electric vehicles illuminates the road ahead. The only question is, are you ready to join the ride?
