Coastal Safari & Hospitality Resort — 30kWp Off-Grid Solar + Water Heating

The Challenge

A boutique eco-lodge and safari camp on Kenya's coast was fully generator-dependent — running 40kVA diesel gensets around the clock to power 24 chalets, a restaurant, spa facilities, and a 12,000L/day desalination unit. Generator fuel and maintenance was costing over KES 380,000 per month, creating a significant sustainability gap for a property marketing itself as an eco-destination.

The Solution

Pergamon Energy delivered a 30kWp hybrid solar + solar water heating system:

• 120 × 250W monocrystalline panels on purpose-built elevated carport and roof structures
• 36kW hybrid inverter array with 3-phase output to match existing distribution
• 48V, 1,200Ah LiFePO₄ battery bank (57.6kWh usable) running overnight and generator backup
• 24 × 200L solar thermal collectors replacing electric water heaters in all chalets
• Generator soft-start integration — generator only activates below 20% battery state-of-charge
• SCADA remote monitoring with alert-to-phone for operations manager

The Result

Metric	Generator Only	Post-Solar
Monthly fuel + maintenance	KES 380,000	KES 62,000
Generator run-hours/day	24h	2–4h (battery top-up only)
Water heating electricity load	Included above	Zero (solar thermal)
Estimated annual CO₂ saving	—	~220 tonnes
Simple payback	—	4.6 years

The lodge now prominently features its solar credentials in its sustainability report and has seen an uptick in eco-conscious bookings since the installation.
