To help you visualize the long-term savings of switching from diesel to solar, let's look at a typical ROI (Return on Investment) analysis for a medium-sized industrial kitchen in Nigeria.
ROI Calculation: 10kVA Hybrid Solar vs. Diesel Generator
We will compare a 10kVA Solar/Lithium System against a 20kVA Diesel Generator running for an average of 8 hours per day (covering typical grid outages).
| Cost Component (3-Year Period) | 20kVA Diesel Generator | 10kVA Hybrid Solar System |
| Initial Purchase | ₦18,000,000 | ₦16,500,000 |
| Fuel/Charging Cost | ₦43,800,000 (at 10L/hr, ₦1,500/L) | ₦0 (Sunlight is free) |
| Maintenance/Service | ₦3,600,000 (Oil, filters, labor) | ₦450,000 (Cleaning panels) |
| Battery/Engine Overhaul | ₦2,500,000 (Top-end rebuild) | ₦0 (Lithium lasts 10+ years) |
| Total 3-Year Expense | ₦67,900,000 | ₦16,950,000 |
Total Savings over 3 Years: ₦50,950,000
Recommended Equipment Checklist by Business Type
Based on your power constraints and professional needs, here are the configurations we recommend for 2026.
1. The Professional Bakery
Essential Gear:
Gas-Powered 2-Deck 4-Tray Oven (Reduces electric load by 80%), 20L Industrial Cake Mixer, and a Bread Slicer.Backup Recommendation: 5kVA Inverter + 2 Lithium Batteries. This easily runs the mixer and slicer since the oven uses gas for heat.
2. The Restaurant/Quick Service Spot (QSR)
Essential Gear: 3-Burner Gas Shawarma Machine, Double Tank Electric/Gas Fryer, Bain Marie, and a Double Door Showcase Chiller.
Backup Recommendation: 10kVA Hybrid Solar System. The heavy lifting is done by gas, while the solar handles the constant cooling and food warming.
3. The Hotel/Large Catering Kitchen
Essential Gear: Commercial Dishwasher, 6-Burner Industrial Range, Walk-in Cold Room, and Industrial Ice Maker.
Backup Recommendation: 20kVA - 50kVA Soundproof Generator + 15kVA Solar Buffer. The solar handles the lighting and basic fridges 24/7, while the generator kicks in only when the heavy Dishwasher or central AC is active.
Next Steps for Your Installation
To ensure your kitchen is "grid-failure proof," we recommend the following professional path:
Load Audit: Have a technician from Royal Coast Technologies measure your actual "Startup Amps" for your mixers and chillers.
Phase Balancing: If you have 3-phase power, ensure your "always-on" appliances are balanced across phases so your inverter doesn't overload.
Procurement: Purchase your
Industrial Kitchen Equipment andPower Backup Systems directly from Kara Nigeria to ensure compatibility and warranty coverage.
