Earn Whilethe Sun Shines
Engineering-led solar EPC solutions for CHSL, Commercial and Industrial clients across Maharashtra - from design to commissioning with clarity, compliance and proven performance.
Why The Name "Koku"?
"Koku" is a Japanese unit of volume, traditionally representing the amount of rice needed to feed a person for one year. It symbolizes dependable, life-sustaining energy — the foundational principle behind our mission to deliver safe, reliable solar power solutions.
Engineered to Maximise Returns
We exclusively serve housing societies and commercial/industrial facilities — the two segments where solar engineering, regulatory compliance, and structural rigour matter most.
Zero Out Society Common Electricity Bills
The Problem
Common electricity bills for lifts, water booster pumps, and passage lighting drain maintenance funds every month.
What We Do
We engineer elevated rooftop plants connected directly to your common meters — eliminating recurring electricity costs while keeping your terrace fully usable.
Reduce Heavy Daytime Grid Tariffs
The Problem
Commercial power tariffs in Maharashtra run at ₹12–15/unit, eating directly into operating margins.
What We Do
Custom CAPEX and OPEX rooftop installations designed for factory sheds and commercial terraces — engineered for maximum daytime offset.
Overcoming Urban & Regulatory Challenges
Most solar installers can mount panels on a shed. We solve the problems they walk away from.
Durable Structures
Housing society terraces are spaces shared by residents, water tanks occupy critical area. Generic ground-mount or ballast systems block this utility entirely.
We design and fabricate hot-dip galvanized, non-penetrating elevated structures that rise above water tanks and lift machine rooms. The entire array sits 8–10 feet above the slab, preserving full terrace access while generating power overhead. Every structure is backed by a STAAD.Pro wind-load analysis and a structural stability certificate.
Pioneering Virtual Net Metering (VNM)
Many high-rises in Mumbai and Thane simply don't have enough roof space to offset all their common-area consumption. Virtual Net Metering allows societies to source solar credits from an off-site plant, distributed proportionally across individual flat meters.
Koku Solar is actively fighting at the regulatory forefront — we have filed 9+ VNM applications and secured a landmark MERC ruling (Case No. 222 of 2024) mandating that MSEDCL expedite VNM processing. We don't just install — we advocate.
