One of the first domestic Tesla Powerwall storage solutions has recently been installed at a residential customer’s home the U.K. in the southeast England county of Essex.
Completed on March 22, the install was among the first of its kind in the U.K. as the domestic solar market shifts from the surging growth that has characterised it over the past two years to one of greater self-consumption and storage of solar energy.
The installation of the Tesla Powerwall took four hours, Matthew Jackson, installation manager, told pv magazine. “The installation required just two installers, and the design followed a survey by our in-house surveyor, who compiled a cad drawing and schematics. Apart from the weight (the Powerwall weighs 95kg), there was not much to it other than the complex wiring arrangement,” Jackson said.
The Powerwall was placed on to a north-facing, solid masonry wall at the request of the homeowners. With very little noise associated with the running of the Tesla, this location was preferable because it allowed close proximity to the internal wiring of the PV system.
The installation was a retrofit to an existing solar PV array, but Jackson said that this posed very little in the way of additional difficulties. “The only real complication with a retrofit including this type of battery is where it will physically fit, or where is the safest place for it to be installed,” he said.
The installer added that SolarEdge’s “almost non-existent” failure rate meant that the system support for the Tesla battery is likely to be reliable, and that the install is a close to “plug and play” as any on the market. “The fact that we can set up the system with the StorEdge, and come away and check the following day that it is running online, is invaluable when your teams are working past sun-down at busy periods.”
Last month, pv magazine reported on the first Tesla install in Germany, following the hotly anticipated battery’s roll-out into the Australian and U.S. markets.
