The off-grid problem: trapped by diesel
Islands, remote resorts, and villages beyond the utility lines depend on 100% diesel gensets — which come with real problems:
- Power costs several times more — diesel electricity is far pricier than grid rates, plus the cost of hauling fuel to remote sites
- Frequent outages — one genset fails and the whole system goes dark, hitting resort guests and households
- Noise and pollution — a genset running non-stop disturbs the resort atmosphere and emits high CO₂
- Fuel risk — volatile prices, shortages, and handling risk during transport
The solution: a Solar Hybrid Microgrid
A Solar Hybrid Microgrid combines solar + battery + genset into one system that delivers continuous 24/7 power.
How it works:
- Solar (PV) — the main daytime source, supplying load and charging the battery
- Battery (BESS) — stores solar energy for nighttime use and keeps the grid stable
- Genset (backup) — runs only when solar + battery aren't enough
- Microgrid Controller — coordinates everything and enables remote monitoring
Why you need an AI/controller, not just wired-together sources
Simply connecting solar, battery, and diesel together isn't enough — you need a controller that forecasts and dispatches to:
- Know when to use the battery and when to start the genset (to minimize run-hours)
- Keep the battery's SOC safe (never empty at midnight)
- Deliver stable power even when a cloud cuts solar output
Real projects worldwide
LEONICS has delivered over 140 off-grid microgrid systems across 8 countries, including:
- Iririki Island Resort, Vanuatu — 710 kW PV + 2 MWh battery, powering the resort 24/7
- Sila Island Eco-Resort, Philippines — 105 kWp solar + 100 kW/285 kWh LFP for an eco-luxury resort
- Ban Raya Resort, Phuket — 280 kWp solar + 250 kW/430 kWh LFP
- Kalangala, Uganda — 1.6 MW solar powering 3,397 households and 49 businesses
- Rural villages, Sarawak/Sabah, Malaysia — 125 microgrid systems (2007–2022)
Who it's for
- Island resorts / remote lodges — needing stable 24/7 power plus less diesel noise/pollution for the guest experience
- Off-grid villages / communities — needing reliable electricity for quality of life
- Rural development agencies — electrification projects reaching remote areas
Frequently asked questions
Can it really deliver 24/7 power with no utility line?
Yes — solar supplies daytime and charges the battery, the battery supplies at night, and the genset backs up when needed; the controller dispatches everything to keep power stable.How much diesel cost can it save?
It depends on the solar/battery ratio to the load. Many projects cut it by up to ~60%.If the community/resort expands later, can the system grow?
Yes — it's designed modularly; you can add panels/batteries or connect to the utility line in the future.Can the system be managed remotely?
Yes, every system has a web-based monitoring platform to check status from anywhere.Summary
Off-grid areas no longer have to be trapped by diesel — a Solar Hybrid Microgrid delivers clean 24/7 power, cuts diesel by up to 60%, reduces noise and pollution, and includes remote monitoring.
