Best Residential Solar Compatible EV Chargers UK

solar for home

A few combinations are as compelling as the coupling of solar panels with an EV charge point. The end result is significant savings and a real positive impact on the environment!


We are not new to solar energy in the UK, and in particular, residential solar photovoltaic (PV) systems. Over the past decade, a number of home owners in the UK have installed solar panels on their roof. In fact, the installed solar capacity in the UK has increased from 5,488.6 MW in 2014, to 13,259 MW in 2019. This growth has continued through 2020/ 2021, with a continued increase in the deployment of solar panels in the UK residential market. Homes with solar panels source the electricity primarily from the rooftop solar PV system and not the grid i.e. power is generated and utilised at the residential building.

In general, despite the significant increase in the availability of SMART home EV charging stations in the UK, only a few charge point manufacturers have developed EV charging points compatible with residential solar panels. However, this is now fast changing, as consumers demand for solar compatible EV charge points is on the increase. The reason for this are numerous, but the two primary drivers for increase in consumer demand are ‘lower costs’ and ‘lower environmental impact’ of combining residential solar panels with an EV charging station.

myenergi, a UK developer and manufacturer of high quality EV charging station is fast being recognised for the solar compatibility of its flagship EV charge point, the zappi EV charge point. The EV charge point is available for single-phase and three-phase supply, but given that most homes in the UK are supplied with single-phase, we have highlighted below the zappi 7 kW (single phase) EV charger. The zappi EV charger is combined with the my energi HUB (and CT clamp), to enable the EV charger to become SMART and work with the PV system (and inverter) to draw solar electricity for charging the electric car with renewable power.

Another company keen to also develop traction in the ‘solar compatibility’ segment, is the leading Spain based EV charge point manufacturer, Wallbox. The company recently announced that its flagship residential EV charge point, the Wallbox Pulsar Plus has been upgraded for solar compatibility.

Like myenergi, EO Charging is a fast growing UK EV charge point manufacturer. The company’s flagship home EV charger, the smart EO Mini Pro 2, is solar compatible. The EV charger is one of the smallest in the market, light weight and easy to install. A perfect addition to any home seeking a discreet EV charger!

Though the Tesla EV charger (Generation 3) can only take advantage of solar generation via the Powerwall, we have also included it in our list, given the overall value proposition of combining the Powerwall battery storage, solar generation and EV charging.

Of course for homes that do not have battery storage, the best time to charge an electric vehicle with solar energy will be during the day. During the night and on cloudy days, when solar energy is either not available or solar generation is low, the EV charger will automatically draw electricity from the main grid during the charging session. We recommend homeowners to also install an energy storage battery, as most EV owners charge the EV overnight.

The time taken to charge a battery-electric vehicle (BEV) or a plug-in hybrid electric vehicle (PHEV) using solar, will depend on a number of factors to include the size of the EV battery (kWh), the size of the residential PV system, and the real-time on-site solar energy generation (based on weather conditions). The average residential solar system in the UK is 3.25 kWp and assuming a sunny day, limited load requirement from other household appliances, and an average EV battery size of 60 kWh, it could take up to 8 hours to charge up to 80% of the EV battery.

Installing a solar compatible EV charger, is really quite as straightforward as installing a standard EV charger. A suitability qualified installer is all you need. We at e-zoomed offer high quality installation at competitive prices. To receive a quotation, simple email us at shop@ezoomed.com.

Top Reasons Why Solar Electricity Is Popular For Home Owners For Charging An EV


Advantages: Residential Solar Energy For EV Charging
Lower household energy costs: Significant savings on utility bills. No need to pay inflated 3rd party supplier prices. Generate electricity at zero-to-nominal cost (as households migrate to EVs, household energy use will increase substantially as a result of EV charging)
Future proof: Protect against future increases in electricity prices. Potential increases in electricity prices are a ‘real and significant’ risk to households
Earn money: Export energy to the grid and earn money, when not consuming!
Environmentally Positive: Generate clean and green energy at home (remove the dependence on dirty energy)
Zero-tailpipe emissions: Achieve emission-free EV driving by charging your electric car with green energy (well-to-wheel emissions). Driving an EV charged with dirty energy does not result in zero-tailpipe emission driving
Availability of cheaper electricity 24/7: No need to depend on off-peak hours offered by 3rd party energy suppliers to charge your EV! Charge you EV anytime from Peak to Off-Peak hours and drive your EV at lower cost!
Government incentives: Take advantage of national and regional government incentives that support residential sustainability solutions like solar PV systems and EV charge points
Improve National Grid stability: Every home generating electricity reduces the demand burden (load) placed on the National Grid infrastructure
An environment Ambassador: Become an Environment Ambassador for your neighbourhood by leading by example
Further enhances the attractiveness of the property for potential buyers

Of course, do keep in mind that for the installation of a PV system and EV charging stations, there are upfront costs. However, a combination of the money saved and incentives, make the initial investment worthwhile!

Company Overview: EO


EO Charing is a UK electric car charging station manufacturer. EO stands for ‘Electricity Online’. EO charging was set up by Charlie Jardine in 2015, after having worked with another charging infrastructure manufacturer in the UK.  Charlie, identified an opportunity to create electric vehicle (EV) charging products that were better quality and more reliable than incumbent manufacturers in the market. With ‘simplicity and reliability’ as core themes in the concept DNA, Charlie has successfully navigated EO from an ‘idea’ to an established ‘EV charging manufacturer and smart software’ company. 

Though EO manufacturers residential and commercial EV chargers, the company has a particular focus on developing charging solutions for EV fleet operators. Fleet customers include, Amazon and other leading fleet operators. The company provides a complete EV charging solution to include, hardware design, manufacturing, installation and hardware-agnostic charging management software and services.

For home EV charging, EO has three models, the EO Mini, the EO Mini Pro 2 and the EO Basic. We recommend the EO Mini Pro 2, given its higher level of technical specifications, to include solar compatibility. A better long-term investment compared to the EO Mini and EO Basic.

For business charging, the company offers both AC and DC EV chargers. For AC business charging, the flagship product is the EO Genius. For DC charging, the company provides turkey solutions from 25 kW to 480 kW.

The company sells products in the UK and a number of international markets to include, Ireland, Europe and the Asia-Pacific region. To date, the company has deployed over 50,000 EV chargers. The company has 130 employees and is in the process of listing on the U.S. NASDAQ stock exchange.
