Continuous power supply, independent of grid reliability.

We design, build and operate energy systems that keep mines, agri-processors, factories, hotels and institutions running when the grid fails — solar, storage and energy management under one contract, from Malawi to Ukraine. Financed as EPC, lease or PPA, and maintained under a 7–10 year service contract. 350+ installations delivered across 16 countries.

Three problems we fix

The problem
200+ hrs / month
Without power, in our hardest-hit markets

Outages stop production

Firms lose an estimated 5–16% of annual revenue to power cuts. Malawi has run 3–4 hours of load-shedding a day through 2025–26.

3–5×
The cost of grid power, for diesel

Diesel fills the gap, expensively

Around 80% of businesses run their own generator, at $0.40–0.60/kWh. Fuel prices and currency depreciation make it worse every year.

46%
Of firms cite electricity as their biggest constraint

Unstable supply kills equipment

The voltage sags below tolerance under load and frequency wanders off 50 Hz. Breakers trip, drives burn, motor life shortens.

Two ways to get your system
Option 1

Turnkey EPC

You own the asset. We take single-point responsibility from energy audit and yield modelling through system design, procurement, duty-exempt import, installation and commissioning — then operate it for you under a 7–10 year O&M contract.

Scale
From 200 kWp to multi-MW, rooftop or ground-mount
Timeline
14–22 weeks in Malawi, 20–32 in Ukraine

We do the engineering and the quality sign-off, our contracted local crews do the installation. We hold full responsibility for both.

Option 2

Financed — PPA or lease

We arrange the finance and own or lease the system on your site. You pay for power or a fixed monthly fee instead of capital expenditure — priced below your blended grid and diesel cost, in EUR- or USD-linked terms where required.

Capex
None — structured as PPA, lease or hire-purchase
Energy cost
Below what you pay today for grid and diesel, fixed for the contract term
Bankability
Finance-grade feasibility documentation, DFI-tested

One system, three modes, automatic

The system

The hybrid system watches the grid continuously and switches without operator input. Solar, battery, grid and any existing generator route through one power conversion system with an energy management layer, forming a stable 230/400 V supply on the load side.

Mode A

Grid is within tolerance

Grid passes through, solar contributes what it produces, batteries charge to full. Rare in practice.

Mode B · most of the time

Grid is fluctuating

The converter rides through the swings and conditions its output. Your equipment sees stable voltage and frequency while solar and grid keep charging.

Mode C

Grid is out of range

Instant isolation. The site runs on battery and solar with 3+ hours of full-load autonomy as standard, sized to your requirement. No flicker, automatic reconnection.

What happens when the grid does not behave

How it behaves

Pick a grid condition and watch where the power comes from — then switch to what the same site goes through today.

What the grid delivers sags and drift
What your equipment sees clean 50 Hz

Illustrative, not a measurement or a design. Line thickness follows the power on each path, and time is compressed. Real behaviour depends on your load profile and grid connection — which the free energy audit establishes.

The economics

What it costs, on your own numbers

Every site is different, so a single reference case is worth less than your own. Send us your consumption and we model the system, the yield and the price against what you pay today for grid and diesel — before anything is signed.

Modelled on your metered profile, local tariffs and current fuel prices. Indicative until an audit confirms it.

How the saving is made
SolarCarries the daytime load directly, at a cost fixed for the life of the asset.
StorageMoves that energy into the evening and through outages, so the generator does not start.
GridKept as backup rather than as the primary supply, and charged to the battery when it is within tolerance.
DieselFalls to a fraction of current burn — this is where most of the saving comes from.

Who we build for

Sectors
S/01

Mining & extractives

Niobium, rare earth, rutile, graphite and uranium sites where diesel sets the marginal cost of every tonne produced.

S/02

Agri growing & processing

Cashew, dairy, food processing and irrigation — seasonal peaks and refrigeration duty cycles, sized with storage.

S/03

Retail & manufacturing

Flat daytime load profiles that solar matches almost perfectly, delivered without stopping the line or the trading day.

S/04

Hospitality

Lodges, hotels and group roll-outs where silence, reliability and fuel logistics all carry real cost.

S/05

Hospitals & institutions

Hundreds of health facilities and schools already run on systems we built and maintain. The same engineering is available to private hospitals and campuses, as EPC or an energy-service contract.

S/06

Municipal utilities

Water utilities and district heating, with capex blended from municipal grant windows and paid from tariff revenue.

S/07

Humanitarian & development

Long-term agreements with UNICEF and the World Food Programme. Programme owners get the same delivery standard our commercial clients do.

S/08

How a project runs
PHASE 1 · 2–4 WEEKS

Energy audit

Load profiling, metered logging and payment-capacity check. Free to qualified sites, ending in a term-sheet proposal.

PHASE 2 · 4–6 WEEKS

Design & feasibility

System design, LCOE analysis and a bankable feasibility report with the financing structure attached.

PHASE 3 · 8–12 WEEKS

Build & commission

Procurement on a standardised bill of materials, duty-exempt import, installation under our supervision and quality sign-off.

YEAR 1–10

Operate & report

SCADA monitoring from our Lilongwe operations centre, SLA management, scheduled service and local response.

Where we work

Markets
Anchor market

Malawi

More solar and storage sites per capita than any other operator in the country. Import routes, duty exemptions, a legal entity, an office and a Lilongwe operations centre already in place, with 3–4 hours of daily load-shedding and grid restoration running to 2027.

Second C&I market

Ukraine

Distributed solar and storage is now the default after most thermal generation was damaged. A distributed plant is repaired in about a week against months for thermal — resilience is the product. First UN solar and BESS programme in delivery.

Start here

Send us two months of energy bills.

That is enough for us to model a system, a yield and a price for your site. If you do not have them to hand, your monthly spend will do to start. The energy audit is free for qualified sites, and you get indicative numbers before anything is signed.
