Quick answer: A 100KW configuration from Mars Solar, built for off-grid and backup use. CE/ROHS certified, 25-year panel life, factory-direct pricing, shipped to 130+ countries.
David, a Nigerian resident living in Guangzhou, China, has become a true "China expert" after spending 20 years in the country. His family in Nigeria operates 15 hotels, and David is responsible for procuring supplies for all their needs. In recent times, the soaring diesel prices in Nigeria, David's urgency to install commercial solar power in each hotel for stable and cost-effective electricity supply has intensified.

After thorough research and understanding the market, David reached out to Mars Solar and connected with Karen, one of our sales engineers. Karen invited David to our factory to discuss the commercial solar power project for the hotels in person, along with our project engineer, Gavin.
As a project engineer with 10 years of experience, Gavin has just completed work on a 400KW solar electric generator in the Philippines.During the meeting, Gavin gained insights into the load and electricity usage in David's hotels, enabling him to design suitable commercial solar power for each establishment.
Your NERC supply band and DisCo change the arithmetic
Each hotel's saving depends on the hours its feeder delivers. NERC sorts feeders into five bands by guaranteed daily supply, from Band A at 20+ hours down to Band E at 4–8 hours.
₦209.5 is the Band A rate for ten of the eleven distribution companies. Enugu Electricity Distribution Company (EEDC) is the exception at about ₦160/kWh, covering Enugu, Anambra, Abia, Imo and Ebonyi — so a quote built on ₦209.5 overstates savings for those states by roughly a quarter. Bands B to E vary by DisCo and no single national figure applies.
Band A has been held at ₦209.5/kWh since July 2024, with the MYTO order in force since late 2025. As of late 2026 no increase has been approved.
In collaboration with David, Gavin meticulously crafted a series of engineering drawings for the installation of the commercial solar power systems. Considering the specific requirements and load profiles of each hotel, the designs aimed to maximize efficiency and ensure a stable and sustainable power supply.
David was very satisfied with Gavin's 100KW solar electric generator design and decided to use one of the hotels as a pilot project. If successful, it will be rolled out to all 15 hotels.

Frequently asked questions
Why did rising diesel costs push these hotels to solar?
Soaring diesel prices in Nigeria made generator-dependent power increasingly expensive across a 15-hotel estate, so the buyer moved to commercial solar for stable and cost-effective electricity supply.
What configuration was chosen?
A 100KW configuration from Mars Solar, built for off-grid and backup use, CE/ROHS certified, with 25-year panel life and factory-direct pricing.
Does each hotel's supply band change the sizing?
Yes. NERC sorts feeders into five bands by guaranteed daily supply, from Band A at 20+ hours down to Band E at 4–8 hours, so each hotel's load and outage pattern drives the final design.
