See the exact 10-day to 21-day timeline SRISHTI SOLAR ENERGY follows to design, bolt, earth, wire, and grid-synchronize a rooftop solar plant in Bihar.

A clean installation relies on civil precision as much as electrical engineering. At SRISHTI SOLAR ENERGY, our 5-stage deployment pipeline guarantees leak-proof roof anchoring and clean conduit routing:

  1. Digital Shadow & Load Audit: Measure sanctioned load (kW), inspect parapet wall heights, and determine south-facing tilt (~24°–26° optimal for Bihar latitude).
  2. Chemical Waterproof Anchor Grouting: Drill HDGI base plates and seal with industrial waterproof anchor adhesive to eliminate roof seepage risk.
  3. Module Assembly & MC4 Crimping: Torque-tighten panels with stainless-steel mid/end clamps and crimp UV-stabilized 4 sqmm/6 sqmm DC solar cables inside PVC/GI conduits.
  4. Safety Protection & Earthing: Connect ACDB, DCDB, lightning arrestor, and three separate copper-bonded chemical earthing pits.
  5. DISCOM Bidirectional Meter & Commissioning: Coordinate with SBPDCL/NBPDCL junior engineer for net meter synchronization and live Wi-Fi generation app handover.
