Portfolio overview
Live output, earnings, open incidents and season losses for the Aralvaimozhi wind cluster and the Thovalai solar park.
Aralvaimozhi Wind Cluster
24 × 250 kW in Class 1/2/3 + 2 × 3 MW pilotThovalai Solar Park
25.1 MWp DC · 20 MWac · 8 invertersActive incidents
Last wind season
Portfolio energy outlook: next 7 days
From fault to fixed, and the client sees every step
SCADA, inverter and meter data every 1–10 min: wind, power, temperatures, vibration, string currents.
Each turbine is compared with the best-run sample in its wind class, so the wind's own variation cancels out.
Root-cause hints (reset pending, gearbox, yaw, blades, inverter, string) with the loss in units and ₹ per hour.
WhatsApp to the owner and the nearest technician: asset, location pin, fault, spares to carry.
Ticket timeline with SLA timers: accepted → on site → resolved, geo-verified.
Monthly and seasonal report: units recovered, ₹ saved, availability, SLA compliance.
Built on real, public weather & climate data
Aralvaimozhi wind farm in 3D
Every turbine sits on the terrain of the pass inside its wind class. Rotors turn at their real RPM, nacelles yaw into the measured wind, and stopped 250 kW machines deploy their blade-tip brakes. Click any turbine for live SCADA.
Season loss audit: one sample turbine, every turbine judged
Wind flow is area-wise, so every cluster sits in a wind class (1, 2 or 3). Inside a class all turbines see nearly the same wind, so the best-run 250 kW sample turbine shows what every other turbine should have produced. Wind is not in our control; the gap between a turbine and its sample is operation and maintenance, and that is what this page measures in units and rupees.

Loss & revenue calculator
"If this turbine doesn't run for 1 day, 2 days, a week, how much do I lose? And if it keeps happening for a year?" Pick a turbine class, a wind class, a month and a duration.

Repowering & life-extension advisor
The 250 kW machines are 22–27 years old. Replacing them ("plucking out and putting in new units") multiplies the energy from the same land and the same grid connection. Pick a class cluster to see the gain, the investment and the TN policy position.

Wind site planner
"I have this much land at this location. If I put up wind turbines, what will I get in a year?" The tool fetches 20-year NASA POWER climatology for the exact coordinates and runs the full turbine model.

Layout & assumptions
Thovalai solar park in 3D
832 module tables under the true astronomical sun for Thovalai. Cloud shadows drift across with the wind and really dim the tables beneath them, and faults are pinned to the exact block, inverter, combiner box, table and string. Switch to Thermal IR to see what a drone survey sees.
Inverters & string heatmap
Every string is compared with its neighbours in real time. Strings in the same combiner box see the same sun, so one running 10% low is a fault, not weather. That is how the platform finds a single bad string among 1,664.

AMC plans: monitoring + maintenance as a measurable service
Three tiers the owner can understand in rupees. Every plan is backed by this platform: the client sees availability, units recovered against the sample turbine, and SLA performance every month.
AMC value calculator: total cost of ownership
Lost revenue is measured against 99% availability and includes undetected under-performance (power-curve drift, late resets, soiling, open strings). Indicative values.
