Harnessing the Sun’s Rays; Tesla Powerwall makes for sustainable family living.

In 2018, as part of the extension and renovation to their stunning listed farmhouse, StuartBarr CDR clients over in Dorchester went the extra sustainable mile. They were keen to ensure that their family home was achieving the lowest possible carbon footprint and as such turned to the latest in renewable technology.

The StuartBarr CDR team built a timber-framed stable block - and installed a solar photovoltaic system which feeds into a Tesla Powerwall 2 – storing energy produced during the day for use in the evening, when domestic energy consumption tends to be higher and solar panels are no longer reaping energy from the sun’s rays.

In this case, the solar PV system was a sizeable 4.2KW array made up of fourteen 300w panels. With the additional technology of solar edge inverters, each panel is installed to operate independently to maximise its efficiency. If one panel is achieving a sub-optimal performance – which may happen if panels are dirty for example – it will not affect the performance of other panels in the bank.

"The Oxfordshire branch of EnergyMyWay, based in Charlgrove and headed up by director Jason Hobbins, were very helpful in providing the information required to accurately specify for our client’s energy requirements,” says Chris Noonan, StuartBarr CDR Construction Director. "They supplied and installed all of the elements required, including the Tesla Powerwall and worked closely with the team throughout".

The timber-framed stable block was a client designed project, manufactured and assembled by English Heritage Buildings, with whom the Barr Group have worked hand-in-hand with many times before. The StuartBarr CDR team completed groundworks, electricals, plumbing, flooring, roofing, and finishing works to coincide with the subcontracted renewable energy and timber frame sub-contractors, as well as around works to the main house. Our client was delighted with an efficient, co-ordinated project roll out and with the end result - an amazingly eco-friendly family home.

The Tesla Powerwall 2 is still a relatively new technology. With current demand outstripping supply, not just in the UK but across Europe and the US, and with the original 6.4KW Powerwall no longer available, would-be owners have no option but to join the queue.
