    The 55-Day Reality

    Indian solar industry average: 55 days. Top decile: 32 days. 23 days of difference = 41% faster cash conversion.

    Strategy 1: Parallelize, Don't Sequentialize

    Most installers wait for full payment → order material → install → DISCOM. Run material procurement and DISCOM application in parallel.

    Strategy 2: Pre-Design at Lead Stage

    Use satellite-based site analysis to ship a design with the proposal — not after. This kills 7 days of "design revision" loops.

    Strategy 3: Vendor SLAs in Writing

    Top 5 vendors should have signed SLAs: 48 hr panel delivery, 72 hr inverter, penalty for delays. Without SLAs, supply chain costs you 5–10 days/project.

    Strategy 4: Real-Time DISCOM Tracking

    Net-metering apps without tracking = silently stuck. Centralize in a project management dashboard with state-specific milestones and DISCOM contact persons.

    Strategy 5: Mobile Field Tools

    Installation supervisors filling paper forms = 2 days of data entry. A mobile PWA captures completion photos, customer signature, and live status. Our mobile app does this.

    The Compounding Effect

    Cut 23 days/project = +12 projects/year per crew of 3. At ₹1.5L margin/project, that's ₹18L/crew of additional yearly profit — without hiring.
