Solar energy is no longer a niche experiment in Nigeria; it has become a driving force in the nation’s energy transformation. What began as small inverter installations for homes has evolved into a multibillion-naira industry powering schools, hospitals, industries, and entire communities. As grid unreliability and fuel costs worsen, solar energy has emerged as a sustainable alternative, reshaping Nigeria’s power narrative.
Across Lagos, Abuja, Port Harcourt, and other major cities, competition among solar providers has intensified. Dozens of companies now offer solutions ranging from rooftop panels for households to utility-scale solar farms and hybrid systems for commercial users. Yet, among the crowd, a few firms stand out, not for flashy marketing, but for proven engineering quality, project scale, and measurable community impact.
Eauxwell Nigeria Limited
Founded in 1987 as a water engineering services firm, Eauxwell Nigeria Limited has evolved into the country’s foremost solar EPC company. The firm made a decisive shift in 2005 when it ventured into solar water pumping, at a time when renewable energy was still largely experimental in Nigeria. That pivot marked the beginning of its transformation into a full-scale EPC powerhouse, with a footprint that now extends beyond Nigeria’s borders.
Eauxwell’s strength lies in its engineering depth and consistent delivery record. With a team of over 200 professionals and an installation portfolio exceeding 120 megawatts of solar PV capacity across Africa, the company has built a reputation for reliability and technical excellence.
The firm’s operations span rooftop and utility-scale solar PV projects as well as advanced battery energy storage systems (BESS), a crucial technology for improving grid stability and energy security in regions with erratic power supply. Its projects cut across industrial estates, public institutions, and rural electrification schemes.
Sustainability remains central to Eauxwell’s ethos. By combining clean energy technologies with environmental stewardship, the company aims to create long-term value for both clients and communities. Its emphasis on quality assurance, ethical business practices, and community partnerships underscores a vision that sees energy as both an economic enabler and a social equaliser.
In a sector where many firms enter and exit quickly, Eauxwell’s presence and technical consistency make it a benchmark for solar EPC performance in Nigeria.
EM-ONE Energy Solutions
Another standout in Nigeria’s solar EPC landscape is EM-ONE Energy Solutions, a company known for its sophisticated engineering and commitment to large-scale renewable infrastructure. Operating for over a decade, EM-ONE has earned credibility through strategic partnerships with UNICEF, the U.S. Trade and Development Agency (USTDA), and the Nigerian government.
Unlike short-term installation firms, EM-ONE undertakes comprehensive EPC projects, from system design to construction, often integrating advanced energy management, smart-grid controls, and battery storage. The company’s Abuja office serves as its West African hub, coordinating multiple renewable energy projects across the region.
EM-ONE has been instrumental in Nigeria’s mini-grid and decentralised energy push, delivering hybrid systems for health centres, schools, and public facilities. Its approach goes beyond power delivery, it embeds technology transfer and local capacity building into every project, ensuring sustainability and local ownership.
Auxano Solar Nigeria
Auxano Solar, established in 2014, has carved a niche as one of Nigeria’s first indigenous solar panel manufacturers. Based in Lagos, the company’s factory produces locally assembled PV modules, supporting the country’s drive to reduce dependence on imports.
Beyond manufacturing, Auxano also executes EPC contracts, deploying solar and hybrid systems for residential, commercial, and industrial clients. By integrating local production with field expertise, the company plays a dual role: advancing Nigeria’s renewable industrial base and expanding access to clean power.
Havenhill Synergy Limited
Abuja-based Havenhill Synergy focuses on off-grid and mini-grid solutions, targeting rural and peri-urban communities where access to electricity remains low. The company has implemented several projects under the Rural Electrification Agency’s (REA) initiatives, combining solar PV and battery storage to power healthcare centres, schools, and small businesses.
Its model aligns with the productive use of energy approach helping communities use electricity not just for lighting, but for economic activities like cold storage, milling, and irrigation. Havenhill’s community-driven business model positions it as a catalyst for inclusive energy access and rural resilience.
Daystar Power Group
Daystar Power has become a key player in West Africa’s commercial and industrial (C&I) solar market. Founded in 2017, the company provides solar-hybrid systems to businesses across Nigeria and Ghana, helping them cut energy costs and reduce dependence on diesel generators.
Its EPC model integrates solar PV with battery and backup systems, offering clients predictable energy supply and reduced emissions. Daystar’s clients include banks, manufacturing firms, and telecommunications operators—sectors heavily burdened by high energy costs.
Acquired by Shell in 2022, Daystar Power’s operations now benefit from stronger financial backing and global technical expertise, positioning it to scale across Africa. The company’s long-term service agreements and performance-based contracts ensure system reliability, making it a trusted name in Nigeria’s renewable energy ecosystem.
