Stop Guessing Your Solar System Size.
Our AI-powered load analysis engine sizes your solar installation based on your actual appliances — not rules of thumb. Get the right inverter, battery bank, and panel count the first time.
70% of Solar Systems in Nigeria Are Incorrectly Sized
Two failure points dominate — and both trace back to the same root cause: sizing by guesswork instead of real load data.
System Trips & Shutdowns
Undersized inverters can't handle the surge current when your AC, fridge, or water pump starts up — causing repeated trips and blackouts right when you need power most.
Batteries Die Early
Undersized battery banks are discharged too deeply, too often. Lead-acid batteries rated for 5 years fail in 18 months. Lithium cells degrade faster than spec.
Money Wasted on Guesswork
Nigerian homeowners spend ₦2–15M on solar systems sized by rules of thumb. When they fail, trust in solar energy as a whole takes the hit.
From Appliances to Exact System Spec
Four steps. Zero guesswork. A solar system sized by engineering — not assumptions.
List Your Appliances
Tell us what you run at home — lights, fans, TV, fridge, AC, water pump, chargers — along with how many and how many hours per day each runs.
Auto-Categorize Loads
Each appliance is classified as resistive (steady draw) or inductive (motor-driven, with startup surge). This is the step most installers skip.
Smart Load Analysis
Our engine calculates total daily energy, peak load, and surge requirements — factoring in simultaneous-use scenarios and inductive starting current.
Get Your Exact Spec
Receive a precise recommendation: inverter size, battery bank capacity (lithium or lead-acid), and solar panel count — tailored to your actual usage.
Steady Power, No Surprises
Resistive loads draw constant power — what you see on the label is what the system needs to deliver. No startup surge, no hidden peaks. Simple to size, predictable to run.
The Hidden System Killer
Motor-driven appliances draw 3–7× their rated power during startup. A 900W air conditioner can pull 3,150W for the first few seconds. If your inverter can't handle that surge, it trips — every single time.
Built Different. Sized Right.
What sets the Uzzina Smart Solar Sizing System apart from spreadsheets, guesswork, and generic online calculators.
Surge-Aware Sizing
We calculate startup surge current for every inductive appliance — something most sizing tools ignore. Your inverter won't trip when the AC kicks in.
Resistive vs Inductive Logic
Every appliance is auto-classified by load type. Motor-driven devices get surge multipliers; resistive loads are sized at face value. Engineering precision, zero effort.
Battery Chemistry Aware
Lead-acid and lithium batteries have different depth-of-discharge limits. We size your battery bank for the chemistry you're actually buying — not a generic "rule of thumb."
Region-Specific Solar Data
Panel count is calculated using real peak sun hours for your region — not a global average. More accurate array sizing means no shortfall and no overspend.
Hardware-Matched Output
Recommendations snap to real inverter sizes available in the Nigerian market (1.5kVA, 3.5kVA, 5kVA, etc.). No theoretical numbers — actionable specs.
Shareable Reports
Save or print your sizing results. Share with installers, compare quotes, or use as a baseline for your own procurement — all from one calculator session.

Aneke Matthew Chukwuebuka
Engineer · Innovator · Creator of S⁴
Matthew is an Electrical Engineer from the University of Nigeria, Nsukka, with hands-on experience in renewable energy systems, circuit design, and control systems engineering. His industrial training at NNPC E&P Limited focused on renewable energy integration in Nigeria's energy landscape — giving him firsthand insight into both the opportunity and the failure points that define solar adoption in the country.
His project work designing a variable-speed turntable for ceramic molding demonstrated how renewable-energy-driven small-scale manufacturing can transform local industry — a blueprint for the kind of practical, engineering-first approach that powers the Uzzina Smart Solar Sizing System.
Our Mission
To eliminate the two biggest failure points in Nigeria's renewable energy deployment — system miscalculation and operational inefficiency — by replacing guesswork with intelligent, hardware-aware solar design. Every homeowner deserves a solar system that works from day one.
