Founder & CEO, SEDNA Energy Systems
From the Founder · Since 2009
Kerala deserved solar done by electrical engineers, not by salesmen with a catalogue.
Akhil founded SEDNA in Cherthala in 2009 after years in electrical systems engineering. Seventeen years and 2,500+ installations later, he still reviews the design of every system that carries the SEDNA name.

Solar on EMI
Pay your electricity bill as EMI.
Install now and pay through your bank in monthly instalments, over 3 to 10 years. We prepare the quotation the bank needs and file the subsidy alongside the loan.

“The consultation was informative, the installation was completed on time, and the entire process was smooth and professional. Within just one month, our electricity bill has reduced by an impressive 99%.”
VValsa PeterKuthiyathode, Alappuzha · 3 kWp
“They did beautiful installation on my Roof at my Villa. They know how to meet customer requirement. Though kseb took 2 months for approvals, they keep me updated weekly status. Very much happy with Sedna installation.”
Bill beforeAbout ₹8,000 every two monthsAfter solar₹180
“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.”
“Before solar our bill was between ₹2,000 and ₹3,000. Now it comes between ₹125 and ₹150, and we received the ₹78,000 subsidy. They worked well, without damaging anything, and finished quickly.”

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.”

Four stages, the same every time. The roof work is the short part; the approvals set the calendar, and we chase every one of them.
Step 1 · 1 hour, on site
Free roof survey
We measure the usable roof, run a shadow study through the day, check the structure and read your load. You get an honest size and a quotation that names every component.

Step 2 · Within days
Design and quotation
A complete design sized to your bill, not to a subsidy slab. ALMM-listed modules and an established inverter, with the exact models written into the quote.

Step 3 · Typically 2 to 6 weeks
Subsidy paperwork and KSEB approvals
The PM Surya Ghar application and KSEB feasibility go in with you, in your own login. Nothing is installed before approval, because installing early can cost you the subsidy.
PM Surya Ghar · filed by us
₹78,000
Paid straight into the customer's bank account after KSEB commissions the system. Never through us.
Step 4 · 2 to 3 days on the roof
Install, commission, service
Structure, modules, inverter, earthing and surge protection. Then the KSEB inspection, the net meter, and the certificate upload that releases your subsidy. After that, no customer waits more than 24 hours for service.

The units your roof will really generate, measured at the survey rather than promised on the phone. If a smaller system is right, we quote the smaller system.
Coastal wind, salt air and three months of rain. Mounting structures and sealed connections chosen from seventeen years of installing in exactly this climate.

Straight answers about cost, savings, installation, subsidy and what happens after you switch to solar.
Yes. For systems of 3 kW and above under PM Surya Ghar, and we file the paperwork with your application. We don't take it on your behalf; it comes directly to your bank account, typically 30 to 90 days after commissioning.
A correctly sized system removes most of your bill. A home paying ₹3,000 a month typically drops to a few hundred rupees, sometimes near zero. The exact figure depends on your consumption pattern and roof, which is what the free survey calculates. Use the calculator on this page for a first estimate.
As a rule of thumb, divide your monthly bill by ₹1,000 to get a starting kW figure: a ₹3,000 bill points to about 3 kW. The honest answer comes from your units consumed and your roof, measured at survey. Beware of anyone who quotes a size over the phone without seeing either.
A standard on-grid system switches off during outages for the safety of KSEB linemen working on the grid. That is a national safety standard, not a defect. If outages matter in your area, a hybrid system keeps essential circuits running from a battery. We recommend based on how often your locality actually loses power.
Output drops on heavy rain days but never to zero, and the annual average we quote, roughly 4 units per kW per day, already includes the monsoon. Net metering banks your sunny-month surplus with KSEB as credit, which you draw back in the wet months. The billing year evens out what the weather refuses to.
The physical installation of a home system takes 2 to 3 days. End to end, from survey to net-metered commissioning, typically runs four to eight weeks, mostly consumed by KSEB approvals and meter availability rather than construction. We chase every stage so you don't have to.
