Home solar cuts EV charging costs by 70% versus grid power, GoSolr South Africa study finds
By Eve
Charging an electric vehicle at home with solar power costs about R85 for a full charge compared with R280 from grid electricity, a 70% reduction, according to a case study by South African residential solar provider GoSolr. The study, part of GoSolr's quarterly Light Paper on EVs, found that the same 400km journey costs approximately R550 in an efficient petrol vehicle. GoSolr co-founder Dr Patrick Narbel reported travelling 7,000km since last filling his petrol tank, using solar and household electricity for mostly urban and suburban trips.
Why it matters
The data provides a real world cost comparison for fleet operators and charge point operators considering solar integration at depots or residential sites in South Africa, where electricity access and charging infrastructure remain barriers to EV adoption. The 70% cost saving versus grid power strengthens the business case for solar paired charging installations.

UK home seller reports buyers worried about installing an EV charger on a driveway detached from the house
A UK home seller said on the r/HousingUK subreddit that estate agent feedback after viewings showed potential buyers were concerned they could not fit an EV charger because the driveway is not attached to the property. The Reddit thread, reported by The Cool Down, asked whether home charging could become a standard buying criterion alongside features such as driveways and en suite bathrooms. Several posters said the possibility of installing a charger mattered more than whether one was already in place.
Why it matters
Charger installability is starting to show up as a factor in buyer sentiment, which points to growing demand for solutions where off-plot or detached parking makes a standard home install hard. This is anecdotal evidence from a single forum discussion, but it hints at a gap that on-street, shared and neighbourhood charging providers could address.
Easelink and Luxshare partner to industrialise automated Matrix Charging in China
Austria-based Easelink is working with Luxshare, a precision manufacturing provider operating in 30 countries, to industrialise its Matrix Charging system for the Chinese market, according to a report posted on 2 November 2026 by Charles Morris. Matrix Charging uses a connector on the underside of the vehicle and a ground-mounted charging pad. Through a technology licence, Luxshare can add the system to its automotive portfolio and offer it to OEM customers, and the two firms are already working on OEM projects to integrate it into future vehicle platforms. Easelink plans to expand its local team in China to support the work.
Why it matters
A licensed manufacturing route into Chinese OEM platforms signals that conductive, hands-free charging is moving towards scaled production, which matters for anyone planning autonomous or fleet charging infrastructure. Procurement teams should watch whether vehicle-side connectors and ground pads become specified at platform level, as that would shape future site design and supplier choices.
Is a 22 kW AC option worth paying for on the Renault Mégane E Tech electric?
Renault's pricing release of 7 July 2026 distinguishes an 11 kW AC onboard charger from a 22 kW option on the Mégane E Tech electric range, but it describes an announced offer and does not confirm that equipped vehicles are available now. Citing Schneider Electric's French FAQ, published on 28 August 2026 and updated on 14 September, the article notes that the manufacturer figure is only a vehicle side ceiling: delivered power also depends on the charge point, the cable, vehicle settings and any load shedding. The FAQ equates 11 kW with three phase 16 A and 22 kW with three phase 32 A, and a three phase 32 A Type 2 cable allows 22 kW while a single phase 32 A cable caps at 7.4 kW. The piece relies on scenarios for a 45 minute public AC stop, not measurements.
Why it matters
For CPOs and buyers of public AC, the 22 kW vehicle option only pays off where the charge point, cabling and load management can actually deliver three phase 32 A, so specification and site power planning matter as much as the car. Dwell time assumptions should be tested against real delivered power rather than headline ratings.
