Systems · On-Grid / Grid-Tied Systems

Bring your electricity bill down to zero, or even negative.

Works in collaboration with the KSEB grid. When sunlight can't meet your needs, the grid supplies the balance; when you generate more than you use, the excess is exported and credited.

    “Every two months our consumption came to nearly ₹8,000. I found SEDNA on social media and contacted Akhil, who explained everything. We installed a 3 kilowatt system in 2020, and I can see the production on my phone.”

  • Bill before₹7,000–8,000After solarMeter rent only
    “Before installing, my electricity charge was between ₹7,000 and ₹8,000. Now there is no charge apart from the meter rent. I installed without the subsidy, but in the first two years I got back more than the subsidy would have given me.”
