Ecospark Energy Solutions is a solar EPC (engineering, procurement & installation) company founded in 2025 by Rina Middya, based at Godrej Waterside, Sector V, Bidhannagar (Saltlake), Kolkata. The business is GST-verified and handles end-to-end solar projects for residential, commercial, and industrial clients across Kolkata and West Bengal.

What Ecospark Installs

The current catalogue includes on-grid solar systems from major brands — Adani (3 KW, ₹2,10,000), Tata (3.5 KW, ₹2,25,000), UTL (3 KW, ₹2,00,000), and Luminous (3 KW, ₹2,00,000) — along with a Polycab Solar BOS Kit (₹15,000) for system components, solar street lighting (from ₹10,500), solar LED street lights with pole (₹14,000), and a 3 HP solar pump system with panel (₹1,60,000) for agricultural use. Since exact pricing depends on site load, roof type, and subsidy eligibility, the listed prices are a starting reference — contact Ecospark on WhatsApp for a site-specific quote.

Choosing Between Solar Brands

Adani, Tata, UTL, and Luminous solar systems differ mainly in panel technology, inverter warranty terms, and price positioning — Ecospark installs all four, so the right fit usually comes down to your budget and how long a warranty you want on the panels and inverter. It's worth asking Ecospark directly to compare brand-specific warranty terms for your project rather than assuming one is universally "better."

On-Grid vs. Off-Grid Solar

An on-grid (grid-tied) system — what Ecospark primarily installs — feeds excess power back into the WBSEDCL grid and draws from it when solar output is low, which is why net metering matters (see below). An off-grid system relies on batteries instead of the grid, which raises upfront cost but works in areas with unreliable grid supply.

WBSEDCL Net Metering & Rooftop Subsidy

Grid-tied solar installations in West Bengal need to be registered with WBSEDCL for net metering so exported solar units are credited against your bill, and residential systems may qualify for subsidy support under schemes like PM Surya Ghar Yojana. Subsidy amounts and net-metering procedures change from time to time, so rather than quoting figures that could go stale, the most reliable route is to ask Ecospark directly — as the installer, they handle the WBSEDCL paperwork and can confirm current subsidy eligibility for your property.
