🔰Here’s what to check before you spend money🔰
Your actual power needs👇
▪️Load audit
List everything you’ll run. Fridge, ACs, pumps, lights, fans, TV, your phone charging business loads. Check the wattage on each.
▪️Daily kWh:
Add it up. Example: 500W average load x 24hrs = 12kWh/day. Most PH homes use 5-20kWh/day.
Peak load: What’s the max wattage if everything runs at once? This sizes your inverter. Don’t buy a 3.5kVA inverter if you’ll run a 2HP pump + 2 ACs.
▪️Roof & space
Roof type:
Zinc, concrete, tiles? Zinc needs special mounting clamps so you don’t get leaks in rainy season.
Shading: Any trees, water tanks, taller buildings? Even 10% shade on one panel can kill 30%+ of string output.
Direction: North-facing is best in Nigeria. East/West still works but ∼15% less yield.
Space: 1x 550W panel ≈ 2.3m x 1.1m. Need 10 panels for 5.5kW = ∼25m² clear roof.
🔰Budget vs System type🔰
| Type | Cost range | Best for |
| **Off-grid** | No PHCN at all. Needs big battery bank |
| **Hybrid****| PHCN + solar + battery. Most popular in
Hybrid is usually best because you get power by day with panels battery as backup
🔰Battery choice🔰
▪️LiFePO4:
6000+ cycles, 80-100% DoD, expensive upfront Best long term
▪️Tubular/GEL:
1200-1500 cycles, 50% DoD, cheaper
Needs replacement every 3-4 years.
🔰Inverter & charge controller🔰
Pure sine wave only for fridge, AC, pumps. Modified sine will kill them
🔰MPPT🔰
MPPT charge controller gives 20-30% more yield, critical on cloudy days.
Surge rating: Fridge/pump startup = 3x running watts. Size inverter 2x your continuous load.
🔰Local issues in weather conditions🔰
▪️Rainy season: Expect 30-40% less solar May-Oct. Oversize panels 20% or rely more on PHCN/GEN
▪️Heat: Keep batteries & inverter in ventilated shade. Heat kills LiFePO4 life.
▪️Lightning: You already asked about this. Install surge protectors + proper earthing. Calabar storms are serious.
🔰Installer 🔰
▪️Get a pro->Bad wiring burns houses.
🔰Future expansion🔰
Design 30% bigger than you need now. Adding panels later is easy, but undersized inverter/battery = full replacement.

I base in calabar location is not a barrier for me
