It’s EV PV
Electric vehicles are no longer an underperforming worthy green novelty. Prices are falling, performance is rocketing and now you can charge up in under an hour.
If you have solar on your property, it can fuel your car for free.
Beware there are several products on the market that claim to be Solar responsive. Many will only respond to generation, not excess, which means you could still be using the grid to charge your car. The only products that are truly Solar compatible that Naked Solar are aware of are listed here. If you have other products that you believe are truly Solar compatible, please let us know.
Here’s our quick guide to the best EV-PV charging systems on the market. Home or business, Naked can install all types of EV Charger to your solar array with minimum disruption. Any questions, call us on 0330 236 9650 .
Myenergi Zappi
Flexible charger that allows you to use excess solar to power up your car. Elegantly designed, the Zappi range offers multiple intelligent controls to fine tune how you charge from eco to fast. Comes with a 3 year warranty. Zappi installations start at £2,168 + VAT, including everything needed to get your My Energi app operational which includes full house energy monitoring and will allow you to link to other My Energi products.
Telsa Home & Business EV Chargers
Although it does not respond to excess solar, Tesla’s home wall charger, available only to Tesla car owners, is fairly priced. Businesses don’t need to own a Tesla to get free destination charging points and only pay for installation. Naked were Cornwall’s first Tesla approved installer. Buy the charger from Tesla for £460 and they’ll put you in touch for installation charges, which are typically around £1338.
Sigenergy EV Charger
AC Chargers (7 kW, 11 kW, 22 kW): These are the more affordable, standard wall-box units, great for everyday charging. Capable of working as a standalone charger for any EV, you only unlock the “smart” features (like charging only when solar is available) if you pair them with a Sigenergy SigenStor battery system.
DC Charging Modules (12.5 kW, 25 kW): These are high power modules that must be slotted into a SigenStor battery stack. They bypass your car’s slower internal AC-DC converter to provide faster charging and enable bidirectional (V2H/V2G) power—meaning your car can actually run your house during a powercut. V2H & V2G are not yet permited on the UK grid.
How much to install?
Installing a charging point in your house or business usually costs between £600 – £2000 on top of the price of the system you choose.
What if I don’t have solar PV yet?
No problem. If you’re thinking of going solar in the future we can install an EV charging point in your home or business, connect it to your main electricity supply and make sure the set up is compatible with solar PV systems.
How long do EV batteries last?
Lithium Ion batteries are nowadays extremely durable. Take a look at this good news story from C&C Taxis in St Austell, Cornwall. Their Nissan Leaf fleet have been really put through their paces with amazing results which show how far electric cars have come, and can go!
