Solar battery trailers on standby contracts for cyclone-hit clinics and camps
TL;DR Stormcrate keeps a fleet of towable solar-and-battery units in depots along the cyclone coast and sends them within a day to health centres, water pumps and relief camps after a storm. District and state disaster authorities pay a yearly standby fee plus a daily rate when units go out.
When a cyclone takes the grid down, it stays down for days. Five days after Cyclone Fani hit Odisha in May 2019, about 3.5 million households still had no electricity, roughly 1.56 lakh poles were down and generator owners were charging up to ₹1,000 for half an hour of pumping water into tanks[1]. In Bhubaneswar about half of roughly 4.5 lakh customers were still dark days later[2].
That is exactly when clinics need power for deliveries and vaccine fridges. Diesel sets need fuel trucks on blocked roads, and nobody wants that noise and smoke inside a relief camp.
Each Stormcrate unit is a road-towable trailer with fold-out solar panels, a lithium battery bank and a small inverter. It's sized to run a primary health centre's essentials, a borewell pump, or lights and phone charging for a camp of a few hundred people. A few units carry a diesel set as a backstop for long cloudy spells.
Units sit charged in depots before the cyclone season. When the met department puts out a warning, the district picks priority sites and the trailers roll before landfall or as soon as the roads open. Every unit reports its charge and load, so the control room can see which clinic is running and which one needs a swap.
Off season the same units go out on hire for fairs, film shoots and road works, which keeps the batteries cycled and pays for part of the fleet.
District collectors and state disaster management authorities are the main buyers, on a standby contract plus a per-day rate. State health departments are a second buyer for clinics and cold chain. Right now they hire diesel generators locally, often at surge prices after the storm[1]. Off-season hirers pay normal commercial daily rates.
Lithium battery packs and solar modules now come under BIS compulsory registration, which gives buyers a clear standard to put in tenders[3]. Odisha already tried a mobile solar truck with its disaster authority in 2015[4], so officials won't find the idea strange. Solarised health centres in Karnataka are reporting safer deliveries and reliable vaccine storage[5], and that builds the case for clean backup power at clinics.
No public figure exists for what states spend on temporary power after disasters. The narrow evidence is how big each outage gets - 3.5 million Odisha households without power five days after one storm[1], and the surge prices generators could charge. Adjacent - research on solar clinics in Karnataka shows health staff value reliable power for deliveries and cold chain[5].
A solar relief truck, built by a development charity with Odisha's renewable energy and disaster agencies, proved a solar truck could do relief work, but it stayed a single prototype[4]. IEEE's MOVE programme found its US truck didn't suit Indian roads and is designing compact kits instead[6]. Your real competition is the local diesel generator guy. What's missing is a ready fleet on contract rather than one-off donations.

Building the trailers is doable with off-the-shelf parts. The hard parts are the government sales cycle, keeping a fleet idle but ready for most of the year and moving units on broken roads within a day. Batteries also age while they wait, so every depot needs a charging routine.
No sector licence covers renting out power trailers, but the hardware and the connections carry rules.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let a model decide which clinic loses power when units run short. That call belongs to the district officials.

I'd back a founder with logistics or disaster-response experience who can sell to district administrations. If you want steady monthly revenue soon then look elsewhere. Before you buy a fleet, get one coastal district to sign a paid standby pilot for five units.
Plan for roughly ₹3–5.5 Cr, most of it in the trailer fleet and depots. A paid five-unit pilot with one district keeps the first spend smaller.
No sector licence, but parts need BIS registration, clinic hookups need a licensed electrician and trailers may need registration. You'll also register on GeM to bid.
Yes, wherever storms knock out the grid and governments buy standby services. Check local product standards, road rules and procurement law first.

Thinking about building Stormcrate or something close to it? The make-or-break work is getting a state to pay for standby before a storm, not after, and that's a pitch I can help you shape. If you need a hand, you know where to find me. Talk to Yash →
