300kW Solar System for Nigerian Businesses
A 300kW hybrid solar system typically costs ₦122,000,000–₦155,000,000 fully installed in Nigeria, and covers a major industrial plant or heavy processing facility running continuous machinery, cold chain, and multiple production lines through an 8–10 hour working day — replacing most or all of a 250–300kva diesel generator's daily runtime.

What a 300kW System Actually Powers
A useful way to size-check: 300kW comfortably runs a major industrial plant or heavy processing facility with continuous machinery and multiple production lines through a normal working day. Here's a typical load for a property this size.
Cold chain & warehousing
Large-scale cold storage, freezing, and distribution warehousing running continuously
Plant offices & admin
100+ offices across a major plant or industrial campus
Heavy production lines
Five or more continuous-duty production lines running through the day
Water & effluent treatment
Site-wide water intake, treatment, and effluent processing systems
Continuous machinery
Large compressors, motors, and process equipment running around the clock
Full-site lighting & security
Plant-wide lighting and overnight security systems across the facility

What 300kW Clients Say
"300kW now runs our continuous rolling operation alongside the plant offices. The team's load modeling caught a peak-demand spike we hadn't accounted for and sized the battery around it."
Obiora Nwachukwu
Managing Director, Steel Processing, Ogun State
"Our bottling lines run around the clock during peak season. Olasupo phased the install across our two production halls so we never had to shut a line down."
Blessing Okonkwo
Head of Engineering, Beverage Bottling, Lagos
"Cold storage compliance was our biggest concern going in. The system has held tight tolerances since commissioning, and the 18-week build stayed on schedule the whole way through."

300kW Solar System — Common Questions
How much does a 300kW solar system cost in Nigeria?
A fully installed 300kW hybrid system typically costs ₦122,000,000–₦155,000,000, depending on battery capacity, roof condition, and cable run distance. This includes panels, inverter, battery storage, mounting, and installation labor.
How much roof or land space does a 300kW system need?
Around 1,800–2,000 square meters of unshaded space. At this size, arrays are usually spread across several rooftops, a dedicated ground-mounted section, or both, depending on the plant layout.
How long does installation take?
16–18 weeks from deposit to commissioning for a standard 300kW install, covering procurement, mounting, wiring, and testing across the facility. Installation is phased around your production schedule wherever possible.
Is 300kW enough to replace my generator completely?
For most major industrial plants running 8–10 hours of daytime load, yes — 300kW with an appropriately sized battery can cover the majority or all of daily operating hours. Continuous 24-hour heavy processing loads may need battery sizing above the standard range, or a larger system. We size this properly before you commit.
What warranty comes with a 300kW system?
10 years on panels and our installation workmanship, with 5–10 years on the inverter and battery depending on the brand selected. We'll walk through exact terms for your chosen equipment before you sign off.
