A London property owner fitted matched systems across two separately-metered residential blocks in Hounslow — 81 JA Solar panels in total, cutting communal landlord supply costs.
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.
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.
Solar4Good designed and installed a 31.2 kWp system for Karan Buttar in Hounslow, London: 81 × 385W JA Solar 385W panels with Growatt MOD 15KTL3-X three-phase inverters (per block). Delivered end to end — survey, DNO application, installation and commissioning — to MCS standards.
