Completely unexpected and unnecessary visit from a recent client this morning.
We do our job day in day out, but happy clients make it all worthwhile.

Sunny Yorkshire days look pretty perfect to us with the SOLARWATT Glass Glass panels installed.
Striking straight lines on this mix of stone and flat roof provide the perfect aesthetics on this beautiful renovated farm and barn site.

On Friday we commissioned the new Fronius fully European Reserva Pro Battery modules along with a GEN24 8kw hybrid inverter to provide the client with 19.9kWh storage as an AC coupled installation 💪🏻
The client already benefits from an older existing Solar PV system which remains unaffected.
Now considering back up options to maximise independence, I’m sure we’ll be back to see this client again soon.

It’s been good to be back at this site to commence work on the second bespoke residential property.
This one will see 26 x SOLARWATT glass glass panels in total across a mix of pitched and flat roof systems☀️

What a beauty 🫶🏻
We originally installed 11 SOLARWATT glass glass panels, A Sigenergy 6kw controller, backup Gateway and 2 x 9kWh batteries.
The client soon requested a further 9kWh battery module to provide 27kWh of storage and an EV charger so we popped back this week to install those additions.
With seamless switchover in a power cut the client is extremely happy with their system performance and aesthetics 🙌🏻

Over the last 16 years we’ve seen some shocking installations by other companies, but never one this bad!
Called in to help this customer as his roof is leaking.
How this array is still on his roof when he lives at the top of an exposed hill is beyond us!
The whole lot has to come off.
Fixings not designed for the roof type, no couplers on the rails, missing clamps… the list goes on.
Please choose your installers wisely!!
