HD-20417 delivered at 18:10 as design revision B, 35 minutes before the due time of 18:45
Kavya Nair sent two options because the 1.8 m water tank shades the south-west corner in the afternoon. Neither goes to purchase until Vikram picks one.
Options against what was soldMarked cells differ from proposal v2
| Sold, proposal v2 | Option A Recommended | Option B | |
|---|---|---|---|
| Modules | 12 × 450 Wp DCR | 12 × 450 Wp DCR | 11 × 450 Wp DCR |
| System size | 5.4 kWp | 5.4 kWp | 4.95 kWp |
| Inverter | 5 kW string | 5 kW string | 5 kW string |
| Structure | Elevated GI, height to be fixed | Elevated GI, 1.2 m at the low end | Elevated GI, 1.2 m at the low end |
| Shade | Not assessed at sale | 1 module in partial afternoon shade from the tank | No shade |
| Generation a year | 7,830 kWh | 7,666 kWh −164 kWh, −2.1% | 7,178 kWh −652 kWh, −8.3% |
| Price, GST included | ₹3,02,400 | ₹3,02,400 Unchanged | ₹2,77,200 −₹25,200, at ₹56,000 a kWp |
| Subsidy, separate | ₹78,000 | ₹78,000 | ₹78,000 |
| Changes from what was sold | – | 1 change Generation only | 4 changes Modules, size, generation, price |
Both options differ from what Vikram accepted, so he has to approve one before the buy list is made. Option B also changes his price. The subsidy stays ₹78,000 either way, because both systems are above 3 kW.
Option A layout12 modules
Roof plan: 2 rows of 6, tank shadow over 1 module after 15:00
Option B layout11 modules
Roof plan: 6 + 5, south-west slot left empty

Kavya's note18:10
"I recommend option A. It keeps the size Vikram bought; one module loses some afternoon sun to the tank, about 2% a year. Option B drops that module and the shade, but makes about 490 kWh a year less than A."
