My GEMS Dream House: 9.2 kW PV + 5kW A-W Heat Pump

Thought I'd share what is probably the best residence I've had the pleasure of helping out with. EnerPHit retrofitted detached house with 9.2 kW of Sharp 400W panels (w/ optimizers across 3 aspects) paired to a three phase 8kW SolarEdge inverter. On the hot water and heating front, a 5kW Vaillant Air Source Heat Pump will heat a 300L indirect cylinder and the home via underfloor heating + T22 radiators. No battery. £19K installed for the PV + heat pump + cylinder 
The calculated heat loss is 10 watts per square metre at -2C. The owner will likely never pay for energy ever again! Droool!

That looks amazing!! Impressive fitting of panels around those dormers! My in-laws have a similar shaped roof and serious PV envy so I’ll show them these to show it can be done 👍Smart Tech Specialist with Octopus Energy Services (all views my own). 4.44kW SW Facing in-roof array with 3.6kW Givenergy Gen 2 Hybrid inverter and 9.5kWh Givenergy battery. 9kW Panasonic Aquarea L (R290) ASHP. #gasfree since July ‘231

Cheers! They will need optimizers due to shading from both sides and will generate less due to this, but still entirely worth doing IMO!DougMLancs said:That looks amazing!!

Nice install and a good amount of solar panels installed there... but surely they will still need to use grid electricity in the winter when it's dark and cold (ie. Need the heating on!)Screwdriva said:

Not as much consumption as we are used to but yes, they would. That said, they will earn a substantial credit during the summer months via Flux (forecasted between £2.3- £2.8K p.a.) and will consume a fraction of it during the winter months, effectively making the grid their "battery", feeding 50-60 kWh a day of energy to it during the warmer months when it is "dirtiest" and taking far less from it in the colder months when it is much greener.
