How EV Chargers and Solar Panels Work Together

As environmental awareness becomes more prominent and technologies continue to improve year in and year out, combining domestic solar panels or commercial solar panels with electric vehicle chargers is becoming an increasingly popular and eco-friendly approach to powering transportation. This dynamic pairing not only helps to cut carbon emissions, but it also empowers home or business owners by giving them greater energy independence while significantly reducing their annual energy expenses.

In this blog, we’ll examine the intricacies of exactly how EV chargers and solar panels work together to create a powerful and efficient energy system. Let’s start with the basics.

What Are Solar Panels?

Solar panels, or photovoltaic (PV) panels, are devices that transform sunlight into electricity. They are made up of solar cells, usually made from silicon, a material that can generate an electric current when exposed to sunlight. When sunlight hits these cells, it causes electrons to move, creating direct current (DC) electricity. This DC electricity is then converted into alternating current (AC) electricity by an inverter, making it usable for homes and businesses.

What Are EV Chargers?

EV chargers are devices designed to recharge the batteries in electric vehicles. There are different variations of EV chargers, but mainly they come in three main types based on their charging speed:

• Level 1 chargers plug into a regular household outlet and charge slowly.
• Level 2 chargers require a dedicated electrical circuit and charge faster than Level 1 chargers.
• Level 3 chargers (also known as DC fast chargers) provide the quickest charging speeds and are mostly found at public stations.

At East Yorkshire Solar, we specialise in supplying both domestic EV chargers and commercial EV chargers.

The Synergy Between EV Chargers and Solar Panels

Picture this: you arrive home after a long day in your electric vehicle and plug it into your EV charger. This charger is then connected to your home’s electrical system, which is powered up by your rooftop solar panels. Throughout the day, your solar panels have been soaking up sunlight and converting this into electricity. That energy then flows from the panels, through an inverter, and into your home’s electrical panel. From there, it powers your EV charger, refuelling your vehicle’s battery. Even at night, the energy that your panels have captured during the day helps to charge your car while you sleep.

This setup offers a multitude of advantages. First and foremost, it reduces your dependence on the electrical grid and lessens your carbon footprint by replacing energy from fossil fuels with clean, renewable solar power. Additionally, if your solar panels produce more electricity than your household uses, you can even send the surplus electricity back to the grid, potentially earning credits or reducing your energy bills even further. At East Yorkshire Solar, we recognise the environmental benefits of solar energy.

The synergy between solar panels and EV chargers lies in how seamlessly they work together. Here’s a closer look at why this combination is so effective:

• Direct Solar Charging:
  • Efficient DC Charging: In certain setups, solar panels can directly charge an EV battery if their voltage and current align with the vehicle’s requirements. This avoids energy loss caused by power conversion, making it a highly efficient option.
  • Solar-Driven EV Chargers: Solar panels can supply energy directly to EV charging stations, offering a sustainable and renewable energy source for vehicles. This helps ease the burden on the traditional power grid and cuts down on greenhouse gas emissions.
• Grid-Connected Solar Systems:
  • Time-of-Use Savings: Many energy providers offer lower rates during off-peak hours. Charging your EV during these times can significantly reduce electricity costs.
  • Peak Time Energy Management: Solar panels often produce surplus energy during sunny hours. This extra power can be redirected to charge EVs, decreasing grid reliance during high-demand periods.
  • Optimised Solar Utilisation: Surplus solar energy can be stored in batteries or used to run household appliances, including EV chargers. This maximises the use of solar energy and further reduces dependence on the grid.
    
    
• Vehicle-to-Grid (V2G) Integration: V2G is a system that enables electric vehicles to draw power from the electricity grid but also send power back to the grid too. This offers strong benefits for vehicle owners and the grid, including:
  • Mobile Energy Storage: EVs can double as portable energy storage units. When connected to the grid, they can feed stored energy back to help balance supply and demand.
  • Supporting Grid Stability: V2G technology allows EVs to provide services like frequency stabilisation and voltage regulation, contributing to a more stable and reliable power grid.
  • Reducing Grid Strain: EVs can discharge stored energy during peak hours, helping lower the load on the grid and potentially reducing energy costs through load-shifting strategies.

The combination of solar panels and EV chargers become even more efficient and versatile when paired together with a home battery storage system. These systems store the surplus energy your solar panels produce during the day, which can then be used to power your home or charge your electric vehicle when sunlight isn’t available—such as during the night or on overcast days.

What Are the Benefits of Combining EV Chargers and Solar Panels?

We’ve looked at solar panels and EV chargers, as well as the synergy between the two. Now, let’s take a look at some of the benefits associated with combining EV chargers and solar panels:

• Lower Carbon Emissions: Using solar energy to charge your EV reduces reliance on fossil fuels, helping to create a cleaner and greener environment.
• Energy Independence: Producing your own electricity means less dependence on utility companies, giving you more control over your energy supply.
• Cost Savings: Solar power can significantly reduce the expense of charging your EV, especially during times when electricity rates are high.
• Support for the Grid: Vehicle-to-Grid (V2G) technology can enhance the stability and reliability of the power grid.
• Sustainability: Adopting solar-powered EV charging is a step towards a future that’s environmentally sustainable and energy-efficient.

Challenges and Considerations:

While the combination of EV chargers and solar panels offers numerous benefits, there are however some challenges to overcome or at least be understood beforehand:

• Upfront Costs: Installing solar panels and EV chargers requires a significant initial investment, although these costs can often be recovered over time through savings.
• Battery Wear: Repeated charging and discharging may lead to gradual battery wear, reducing its lifespan. At East Yorkshire Solar, our batteries are sourced from only the highest-quality suppliers.

We endeavour to be the leading choice for solar installation and EV charger installation in East Yorkshire. When you choose East Yorkshire Solar, you can rest assured that all our panels are protected with a 12-year workmanship guarantee, along with many other benefits from our experienced and highly-skilled team.
