An old off-grid system, renewed
Older off-grid systems, including ANERT-era TATA installations, get a new SEDNA power conditioning unit and batteries instead of being scrapped.

What We Do
Five services, one team, since 2009.
From the first measurement on your roof to the service call in year eight, done by SEDNA's own engineers and technicians.
Site survey & consultation
Our solar engineers assess your premises in person, checking roof structure, shading through the day and load profile, and advise the best option for your site and the policy in your region.
System design & installation
A carefully constructed, complete design is the foundation of a successful PV system. Our installation team is timely and efficient, led by professionals with over a decade in the sector.
Solar system services
A dedicated service team delivers complete, construction-ready plans on budget and on time: panel maintenance, operation & maintenance, and system health checks.
Panel cleaning
Clean glass maximises generation. Our cleaning process keeps it simple, efficient and convenient, so your system keeps producing what it was designed to.
Maintenance & after-sale support
A dynamic service team, reachable round the clock, 365 days a year. No customer is kept unattended for more than 24 hours. That is how our reputation was built.
Solar AMC and cleaning
A full health check, not a quick wash.
Dust, bird droppings and Kerala's salt air cost generation slowly, and loose connections and failed surge protectors give no warning. On every service visit, our technicians work through the same checklist:
- Distribution box readings and the inverter's yearly generation data
- Battery health and terminals, on hybrid and off-grid systems
- Surge protection devices, cables and the earth resistance
- Structure and fasteners: corrosion treated, every point re-tightened
- Shade from trees that have grown since installation
- Panels cleaned the safe way: soft water and a soft brush
A hybrid system's service visit, three years on · 1:21
At Ramanattukara, Kozhikode: DB parameters, battery health, yearly generation data, surge protectors, cables and the earth value checked; corrosion treated, a growing tree's shade reported, batteries cleaned and every point re-tightened.
Old System Upgrades
An old system is worth upgrading, not scrapping.
Panels last far longer than the electronics around them. We upgrade older solar systems and home inverters, ours or anyone's, to what you need now.
Off-grid to on-grid
Where KSEB supply is now steady, an off-grid system can be converted to on-grid and enlarged: one customer went from 1 kW off-grid to 3 kW on-grid.

Your home inverter, made solar
An existing home inverter and battery can be turned into a small solar system with panels and a charge controller.
off-grid · 2020
On-grid, with backup for power cuts
A hybrid charger and battery added beside an on-grid system keeps the house running when KSEB fails.
