01 / ECOSYSTEMThe EV-ready household
13.3 kW PV · 24.96 kWh nominal storage · 7 kW chargerOne proposal brought together 28 Trina 475 W panels, a GoodWe roughly 10 kW hybrid inverter, three battery modules and full-house backup scope. The rationale was future electrification, not solar-only payback.
02 / EV CHARGINGSix point six kilowatts and an electric car
Single phase · EV up to 7 kW AC in the proposalA homeowner wanted to run the house and charge an EV on a 6.6 kW array. We explained staggered loads, slower charging and unavoidable grid imports when demand exceeds production.
03 / BATTERIESThe staged battery upgrade
Existing 6.65 kW solar · Sungrow hybridThe existing solar and hybrid inverter could be retained. Options included battery storage alone or additional panels with larger storage capacity. Existing compatibility changed the economics.
04 / BATTERIESThe modest nightly use, future flexibility
About 4 kWh nightly demand in the customer analysisWe considered storage headroom for future use, VPP reservations and degradation rather than sizing only to last night’s demand. The same proposed inverter could manage old and new solar strings with verified limits.
05 / EQUIPMENTWhy the brand price gap exists
Same panels, similar storage · GoodWe vs SigenergyComparisons kept the panel array similar and changed the inverter and battery brand. GoodWe was positioned on proven value, with Sigenergy positioned for architecture and integrated features.
06 / SOLARA smarter east/north/west roof layout
10 east · 6 north · 6 westRather than chasing only north-facing panel count, the design used three roof directions to spread generation across the day. Very short strings on a separate roof may need a design adjustment.
07 / RETROFITWhy replacing old equipment can make sense
Existing optimiser-based SolarEdge arrayRemoving optimisers and relocating strings added labour. In that particular case, a new solar array was quoted only a little higher than retrofitting the old one, due to incentives at the time.
08 / BACKUPBackup versus battery capacity
Essential circuits vs full-house supplyWe explain which circuits are backed up, continuous output and high-load restrictions. Bigger kWh alone does not mean unrestricted blackout operation.
