Reader question on preparing a renovated home for V2H and V2G: leave room in the switchboard now, wait on the charger
By Eve
In a reader Q&A on TheDriven, a reader renovating a home with solar, no battery and a Volvo XC40 Recharge asks what to tell the electrician so V2H or V2G can be added later. The author advises against installing a V2G charger yet, unless taking part in the ongoing Australian trials, but says steps taken now can avoid paying twice. The first is a new switchboard with plenty of expansion room for breakers, cables, energy monitors and sensors, with the author generally allowing double the size needed for the current number of circuit breakers.
Why it matters
For installers and CPOs serving residential customers, this shows the demand for future-ready switchboard and wiring specifications ahead of bidirectional charging going mainstream. It also signals that the advice given to homeowners is to wait on V2G hardware, which affects when that revenue will arrive.

Suniva begins expansion to lift US solar cell capacity to 5.5 GW
Suniva has started an expansion intended to take its US solar cell capacity to 5.5 GW, according to a SUNE stock news update. The report states that long-term customer purchase agreements cover the majority of Suniva's planned production through 2030. The excerpt supplied contains no further figures on investment, timing or customers.
Why it matters
Domestic solar cell supply at this scale, largely contracted to 2030, may tighten availability for developers pairing solar with charging sites, so CPOs planning on-site generation should check how much uncontracted volume remains. It also signals continued US supply chain investment that could affect sourcing and local-content considerations.
Elements Green signs TenneT grid connection agreement for 400MW, 1,600MWh Stadorf battery project in Lower Saxony
Elements Green Deutschland GmbH has signed a grid connection agreement with transmission system operator TenneT for its Stadorf battery energy storage project in Lower Saxony. The project has a planned output of 400MW, a storage capacity of 1,600MWh and a four hour duration, and will connect directly to the extra high voltage grid. The agreement follows a connection construction agreement signed earlier this year, and together the two set the contractual framework for building and operating the grid connection.
Why it matters
Securing both grid connection contracts with a transmission operator is a key de-risking step for a utility scale storage project, and it shows how large German BESS schemes are progressing towards delivery. For CPOs and developers, it is a useful indicator of how grid access and storage capacity may shape the wider power system that charging networks depend on.
Impossible Metals robot recovers 450 grams of seabed nodules at more than 4,000 metres, with no independent data yet
Impossible Metals said its autonomous Eureka robot recovered about 450 grams of polymetallic nodules from the Clarion Clipperton Zone at more than 4,000 metres during a September expedition, as reported by Reuters. The dive was marine scientific research, not production, and the company's release does not describe independent monitoring, so claims of no environmental disturbance come from an investor. The announcement comes 10 days before the first US seabed mineral lease sale, which the company's April 2025 request helped set in motion.
Why it matters
This is a proof of mechanism at research scale, not evidence of commercial supply or environmental outcome, so it should not yet change assumptions about battery metal sourcing. Procurement and CPO teams should treat seabed minerals as a long dated and contested supply question, and watch the lease sale and any independent monitoring data.
