Energy & Power Innovations
Off-grid and renewable power for government buildings, schools and institutional campuses — engineered for hill districts, where the grid is weak, the winters are long and a failed system is a two-day drive away.

Every card carries the same two strips: the hours of the day a technology actually generates, and the months of the year it is strongest. Read them together and the right combination for a site becomes obvious.
Vertical Axis Wind Turbines
Compact 1 kW rooftop and mast-mounted turbines for buildings where wind is available and roof area is not. Generates at night and through cloud and snow.
Solar–Wind Hybrid Systems
A 1 kW turbine paired with a 2.2 kWp array on one 48 V bus. Solar carries the year; wind covers the December–January window when insolation drops.
Micro & Pico Hydro
Where a perennial stream drops 10 m or more near the site, nothing else comes close. Runs 24 hours, needs no storage to be useful, and lasts decades.
Rooftop Solar PV
The workhorse. Grid-tied or off-grid arrays sized to the building’s own load, with HIMURJA state subsidy and PM Surya Ghar support where the site qualifies.
Solar Water Heating
In a hill hostel or residential block, water heating is the single largest electrical load. Evacuated tube collectors displace it directly — usually the quickest return on any renewable spend.
Battery Energy Storage
LiFePO4 banks sized from a measured load profile, not a guess. Correct sizing is what keeps a bank out of chronic deep discharge — the single most common cause of early failure.
Air-Source Heat Pumps
For space and water heating in cold districts, a heat pump moves three to four units of heat per unit of electricity. A resistive heater moves one. The arithmetic is not close.
Solar Water Pumping
Surface and submersible pump sets for campus water supply, irrigation and firefighting reserves — with PM-KUSUM support where the application qualifies.
Solar Street & Campus Lighting
Integrated all-in-one luminaires with LiFePO4 and motion dimming. No trenching, no cabling, no metered load — which is why these clear procurement faster than almost anything else.
Energy Efficiency Retrofit
LED conversion, BLDC fans, occupancy sensing and power-factor correction. The cheapest kilowatt-hour is the one the building never draws — and it needs no generation asset at all.

Vertical Axis Wind Turbines
A 1 kW helical Darrieus rotor on a 9 m mast, with 48 V control, storage and commissioning available as separate scopes. Generates at night, in cloud and under snow — conditions where a photovoltaic array does not.
When it generates
Wind is the one source that works after dark and through overcast. In hill districts its share is proportionally highest in December and January, exactly when insolation falls away. What it will not do is deliver rated output on an average day: rated power is a 12.5 m/s figure, and most sites do not see that.
Specification
| Parameter | Value |
|---|---|
| Rotor configuration | 3-blade helical Darrieus, 2.0 m dia. × 3.0 m height |
| Swept area | 6.0 m² |
| Rated output | 1.0 kW at 12.5 m/s free-stream wind speed |
| Cut-in wind speed | 2.5 m/s |
| Furling / cut-out | 14 m/s, electro-dynamic braking |
| Survival wind speed | 45 m/s |
| Blade material | FRP composite |
| Generator | 3-phase PMG, 48 V, direct drive |
| System DC bus | 48 V |
| Storage | LiFePO4, 3.5 kWh usable (optional scope) |
| Mast | 9 m free-standing galvanised steel |
| Annual yield | 195 – 545 kWh per unit (mid-case 370 kWh) |
| Standards | IEC 61400-2 design; power curve per IEC 61400-12-1 |
Where this fits
- Exposed ridge, pass or plateau sites rather than sheltered valley floors
- Buildings with limited or shaded roof area
- Sites needing generation after dark or under persistent cloud
- Locations where snow cover would take a photovoltaic array offline
- Installations where a visible renewable asset is itself part of the brief
Power curve
Output varies with the cube of wind speed. Stated at 1,500 m AMSL (air density 1.06 kg/m³ against 1.225 at sea level), at a system power coefficient of 0.16. Delivered figures are net of generator, rectifier and controller losses at 80 per cent.

Solar–Wind Hybrid Systems
One 48 V bus, two sources. The array carries the year; the turbine covers the December–January window when insolation in hill districts drops below usable levels and the array alone would leave the battery short.
When it generates
This is the pairing’s whole argument. Solar peaks between March and October and does nothing after sunset. Wind runs through the night and is proportionally strongest in deep winter. Overlaid on one bus, the gaps in each are partly covered by the other — which is what allows a smaller battery bank for the same days of autonomy.
Specification
| Parameter | Value |
|---|---|
| Wind rotor | 3-blade helical Darrieus, 2.0 m × 3.0 m, 6.0 m² swept |
| Turbine rated output | 1.0 kW at 12.5 m/s |

| Controller | Dual-input 48 V — wind rectifier plus solar MPPT |
| Inverter | 3 kVA / 48 V pure sine wave |
| Storage | LiFePO4 48 V, 5.0 kWh usable |
| Design autonomy | 1.5 days at rated supportable load |
| Wind contribution | 195 – 545 kWh per year |
| Solar contribution | 2,275 – 3,950 kWh per year |
| Combined annual yield | 2,470 – 4,495 kWh (mid-case 9.5 kWh/day) |
| Standards | IEC 61400-2, IEC 61400-12-1, IEC 61215 / 61730, BIS registered modules |
Where this fits
- Buildings needing round-the-clock supply with one battery bank
- Sites where solar alone leaves a December–January shortfall
- Campuses with mixed daytime and evening load
- Locations where a smaller battery bank matters on cost or transport
- Phased installations — start with one source, add the second later

Micro & Pico Hydro
Where a perennial stream drops ten metres or more within reach of the building, micro-hydro beats every other renewable here — on cost per unit generated, on reliability and on asset life.
When it generates
This is the only source that runs at full output at three in the morning in January. Flow rises through the monsoon and eases in the dry months, but it never stops the way sun and wind do — which is why a hydro site often needs little or no storage at all.
Specification
| Parameter | Value |
|---|---|
| Class | Pico below 5 kW · Micro 5–100 kW |
| Head required | 10 m minimum; 25 m+ preferred |
| Turbine types | Pelton, Turgo and cross-flow |
| Capacity factor | 50 – 70 per cent |
| Output comparison | A 5 kW set can deliver around 120 kWh/day against 15–20 kWh/day from 5 kW of solar |
| Asset life | 30 – 50 years with routine maintenance |
| Uptime achieved | Up to 98 per cent |
| Civil scope | Intake, settling basin, penstock, powerhouse, tailrace |
| Approvals | State water resources clearance; HIMURJA registration in Himachal |
Where this fits
- Institutional campuses with a stream or spring channel on or adjacent to the site
- Locations with a measurable vertical drop within 500 m of the load
- Buildings needing round-the-clock supply without a large battery bank
- Remote facilities where diesel is currently the fallback
- Sites already holding riparian or irrigation rights
Commercial — priced by scope
Hydro is priced per kilowatt installed because civil works dominate and vary entirely by terrain. The feasibility study comes first and is adjusted against the order value if you proceed.

- Civil works concept and route survey
- Approvals roadmap
Pico set, up to 5 kW

Rooftop Solar PV
Grid-tied and off-grid arrays sized from the building’s own metered load. In Himachal both the central PM Surya Ghar subsidy and the HIMURJA state incentive apply where the site qualifies.
When it generates
Solar is entirely predictable in shape and almost entirely absent for half the day. Hill districts hold above 4 kWh/m² per day in every month except December and January. That December dip is exactly why storage or a second source matters here in a way it does not on the plains.
Specification
| Parameter | Value |
|---|---|
| System types | Grid-tied, off-grid, and hybrid with storage |
| Module technology | Mono PERC and N-type TOPCon, BIS registered |
| Installed cost in Himachal | ₹40,000 – ₹70,000 per kW |
| Specific yield | 1,034 – 1,796 kWh per kWp per year |
| Central subsidy | PM Surya Ghar, up to ₹78,000 for 3 kW and above where eligible |
| State incentive | HIMURJA rooftop subsidy, subject to current notification |
| Structure | Hot-dip galvanised, snow and wind load rated for the district |
| Standards | IEC 61215, IEC 61730; inverters to IEC 62109 |
| Warranty | 25-year module performance; 5–10 year inverter |
Where this fits
- Any building with unshaded roof or adjacent ground area
- Campuses with high daytime load — offices, schools, health centres
- Sites where grid supply exists but is unreliable
- Buildings pursuing a subsidy-supported route to lower running cost
- Phase-one installations that a second source can be added to later
Commercial — priced by scope
Rooftop solar is the one technology here where subsidy can materially change your net figure — we handle that paperwork as part of scope rather than as an extra.

Solar Water Heating
In hostels, residential blocks and health centres, water heating is usually the single largest electrical load in the building. Evacuated tube collectors remove it from the meter entirely.
When it generates
Hot water demand peaks early morning and evening; collection happens in between. A well-sized insulated tank bridges the two, which is why solar thermal needs no batteries and almost no electronics — and why it keeps working when everything else needs a technician.
Specification
| Parameter | Value |
|---|---|
| Collector types | Evacuated tube (ETC) and flat plate (FPC) |
| Capacity range | 100 – 2,000 litres per day |
| 100 LPD system | ₹15,000 – ₹35,000 depending on collector type |
| 300 LPD system | ₹36,000 – ₹80,000 |
| Installation | ₹2,000 – ₹6,000 typical, by roof access and plumbing |
| Cold-climate provision | Anti-freeze loop and insulated hot lines for hill districts |
| Backup | Electric element on thermostat for extended overcast |
| Typical payback | 2 – 4 years against resistive heating |
| Maintenance | Annual tube inspection and descaling |
Where this fits
- Hostels, residential quarters and rest houses
- Health centres with continuous hot water demand
- Kitchens and canteens on institutional campuses
- Any hill building currently running electric geysers
- Sites wanting demonstrable savings inside one financial year
Commercial — priced by scope
Sized from occupancy and usage pattern, not roof area. Oversized thermal systems waste money as surely as undersized ones waste hot water.

Battery Energy Storage
LiFePO4 banks sized from a measured load profile. Correct sizing is the whole job — a bank sized against an optimistic generation figure spends its life in deep discharge and fails inside a year.
When it generates
Storage does not generate; it shifts. The strips show a typical discharge profile — evening and overnight — against a generation window that sits elsewhere in the day. The width of that gap, not the size of the array, is what sets the bank capacity.
Specification
| Parameter | Value |
|---|---|
| Chemistry | LiFePO4 (LFP), integrated BMS |
| System voltage | 48 V and 51.2 V architectures |
| Cost | ₹12,000 – ₹18,000 per kWh at dealer level |
| Cycle life | 3,000 – 6,000 cycles |
| Design life | 10 – 15 years in Indian conditions |
| Depth of discharge | 80 per cent standard; 70 per cent in hot locations |
| Lead-acid alternative | ₹6,000 – ₹9,000 per kWh, 3–5 year life, higher lifetime cost |
| Cold-weather note | LFP charge current is derated below 0 °C — heated enclosure specified for high-altitude sites |
| Monitoring | Cell-level BMS telemetry with remote read-out |
Where this fits
- Off-grid systems of any generation type
- Grid-connected buildings with frequent or long outages
- Facilities running critical loads — health centres, communication huts
- Sites replacing failed lead-acid banks
- Campuses wanting to shift daytime generation into evening use
Commercial — priced by scope
Storage is sized from measured demand. Bring us a month of meter data and the quotation stops being an estimate.

Air-Source Heat Pumps
For space and water heating in cold districts, an air-source heat pump moves three to four units of heat per unit of electricity. A resistive heater moves one. Across a Himachal winter that difference is the entire electricity bill.
When it generates
Heating demand runs opposite to solar availability — heaviest at night and deepest in December and January. That is precisely why heating is worth attacking with efficiency rather than with generation: cutting the load is far cheaper than building an asset to serve it.
Specification
| Parameter | Value |
|---|---|
| Technology | Air-source heat pump, inverter-driven scroll compressor |
| Seasonal COP | 3.0 – 4.2 depending on ambient and flow temperature |
| Operating range | Down to −15 °C ambient with cold-climate models |
| Applications | Space heating, domestic hot water, or combined |
| Energy saving | 60 – 70 per cent against resistive heating |
| Refrigerant | R32 or R290, low global warming potential |
| Distribution | Radiators, underfloor loops or fan coil units |
| Maintenance | Annual coil clean and refrigerant check |
Where this fits
- Hill-district buildings currently heated by resistive convectors or geysers
- Hostels and residential blocks with sustained winter occupancy
- Health centres requiring stable indoor temperature
- Retrofits where a wet distribution system already exists
- Campuses where the winter electricity bill is the dominant operating cost
Commercial — priced by scope
Priced against a heat loss calculation for the actual building. A catalogue number for a hill district building is a guess, and usually a low one.

Solar Water Pumping
Surface and submersible pump sets for campus water supply, irrigation and firefighting reserves — with PM-KUSUM support where the application qualifies.
When it generates
Pumping is the rare load that wants to happen exactly when solar is generating. Fill the tank in the middle of the day and the tank itself becomes the storage — which removes the battery from the system entirely and takes a large cost with it.
Specification
| Parameter | Value |
|---|---|
| Pump range | 1 – 10 HP, surface and submersible |
| Controller | Variable frequency drive with dry-run and surge protection |
| Head range | Up to 200 m with multistage submersibles |
| Storage | Overhead tank rather than battery — the tank is the storage |
| Running cost | Nil after installation |
| Scheme support | PM-KUSUM Component B and C where the application qualifies |
| Modules | BIS registered, on fixed or seasonal-tilt structure |
| Standards | MNRE specification for solar pumping systems |
| Warranty | 5 years on pump and controller, 25-year module performance |
Where this fits
- Campus and village water supply schemes
- Firefighting reserve tank replenishment
- Irrigation on institutional land holdings
- Remote sites with no reliable grid for a conventional pump
- Diesel pump replacement where fuel logistics are the real cost
Commercial — priced by scope

Solar Street & Campus Lighting
All-in-one integrated luminaires with LiFePO4 storage and motion dimming. No trenching, no cabling, no metered load — which is why these clear procurement faster than almost anything else here.
When it generates
Fully complementary by design: charge through the day, discharge through the night. Two nights of autonomy is our standard specification, which covers the overcast stretches that leave single-night designs dark by the second evening.
Specification

| Control | Dusk-to-dawn with PIR motion dimming |
| Pole | 3 – 9 m hot-dip galvanised, wind load rated |
| Installed cost | ₹12,000 – ₹38,000 per pole by output and height |
| Ingress protection | IP66 luminaire, IP67 battery compartment |
| Snow provision | Tilt angle set for shedding at hill-district latitudes |
| Warranty | 3 years luminaire, 5 years battery |
Where this fits
- School and college campuses, internal roads and pathways
- Government office compounds and parking areas
- Village approach roads without existing street lighting cable
- Sites where trenching cost would exceed the lighting cost
- Security lighting at remote or unmanned facilities

LED conversion, BLDC fans, occupancy sensing and power factor correction. The cheapest kilowatt-hour is the one the building never draws — and unlike everything else here, it needs no generation asset at all.
When it generates
Efficiency works every hour the building is occupied, in every month, with no weather dependency whatsoever. It is the only intervention here whose output does not vary — which is also why it is the safest first spend on any campus.
Specification
| Parameter | Value |
|---|---|
| Lighting | LED conversion at 130–160 lm/W with existing fitting reuse where possible |
| Fans | BLDC ceiling fans at 28–35 W against 75–80 W conventional |
| Controls | Occupancy and daylight sensing in corridors, toilets and stores |
| Power factor | Automatic capacitor banks to correct to 0.98 and above |
| Typical load reduction | 25 – 40 per cent of connected load |
| Payback | 12 – 24 months at prevailing institutional tariff |
| Audit | Circuit-level metering over two weeks before any recommendation |
| Verification | Post-installation metering against the same baseline |
| Effect on renewables | Every kW removed reduces the generation and storage you need to buy |
Where this fits
- Any occupied building, on any tariff, in any district
- Campuses planning a renewable installation — do this first and buy a smaller system
- Buildings with high fixed-charge or demand penalties
- Facilities with old fluorescent or conventional fan stock
- Sites where capital budget is tight but operating budget is not
Commercial — priced by scope
The audit comes first and is adjusted against the order value. We would rather find you 30 per cent of savings than sell you a system to serve the waste.
