The challenge
Cutting landlord supply costs across two blocks
Karan Buttar, developing residential blocks in Hounslow through Buttar Construction, wanted to reduce the communal landlord electricity supply costs across two separately-metered buildings.
Communal supply — lighting, lifts and shared services — is a significant recurring cost, making rooftop solar an ideal way to reduce it.
The solution
Dual systems, one per block
Solar4Good installed matched systems across Block A and Block B, using 81 JA Solar 385W panels in total with Growatt MOD 15KTL3-X three-phase inverters, each block on its own meter.
The systems cut the communal landlord supply costs across both buildings, delivered end to end to MCS standards.
The result
What the development gained
81 × 385W JA Solar 385W panels — 31.2 kWp of capacity
Battery storage keeps homegrown power available into the evening
MCS-certified installation — eligible for the Smart Export Guarantee
