Cornerstone Solar is the solar and renewable energy brand of E-Cornerstone Online Resources Company Limited, an established Nigerian company with an operating history dating back to 2014.
We provide reliable solar energy solutions designed to help homes, businesses, organisations and institutions take control of their power supply and reduce their dependence on unstable electricity and costly fuel-powered generators.
From solar system design and installation to sales, maintenance, upgrades and after-sales support, we provide practical energy solutions built around the actual needs of our customers.
Our strength is not just in selling solar equipment. We help customers understand their energy needs, select the right equipment, install it professionally and maintain their systems for long-term performance.
Through our physical locations, Solarite Mall, our installation teams and our verified product channels, we make it easier for customers to access genuine solar products and professional technical services.
Over the years, Cornerstone Solar has completed 5,000+ solar installations and trained 50+ people through our solar training initiatives. We continue to work with reputable manufacturers and distributors across the renewable energy industry, providing customers with access to a wide range of trusted solar and energy products.
Cornerstone Solar was built from a simple but important understanding: access to reliable electricity should not be a luxury.
Our journey began with the desire to provide Nigerians with a better alternative to the everyday struggle with unreliable public electricity supply, fuel costs, generator maintenance and the inconvenience that comes with inconsistent power.
As the demand for dependable alternative energy continued to grow, we evolved from simply providing solar products into building a complete energy solutions business.
We have grown through years of learning, field experience, customer relationships and thousands of conversations with people who needed more than just an inverter or solar panel. They needed a solution that would actually work for their homes, businesses and daily lives.
This experience has shaped the way we operate today.
We don't believe that one solar system should be recommended to everyone. Every building, business and household has different appliances, energy consumption patterns, operating hours and priorities. That is why our approach begins with understanding the customer's needs before designing a solution.
Our journey has also expanded beyond installations. Through Solarite Mall, we provide access to solar and energy products, while our Solar Academy helps equip aspiring solar installers and entrepreneurs with practical knowledge and field experience.
Today, Cornerstone Solar serves customers across different sectors, including homes, offices, hotels, schools, filling stations, salons, restaurants, retail businesses and other commercial establishments.
What started as a response to Nigeria's power challenges has grown into a broader mission: to make reliable, sustainable and professionally delivered energy solutions more accessible to Nigerians.
And we are still building.
To provide reliable, accessible and professionally delivered renewable energy solutions that improve the way people live and businesses operate.
We are committed to:
Our mission is not simply to sell solar systems. It is to provide energy solutions that customers can confidently depend on.
To become one of Africa's most trusted and impactful renewable energy companies, making reliable and sustainable power accessible to homes, businesses and communities.
We envision a future where individuals and businesses can operate with greater energy independence, where clean energy is more accessible, and where professionally designed solar solutions become a normal part of everyday life.
We are building toward a company known not only for the products we sell, but for the quality of our solutions, the professionalism of our people, the trust of our customers and the impact we make.
We assess energy requirements and design solar systems suited to the customer's building, appliances and usage pattern.
We supply a wide range of solar panels, inverters, lithium batteries, charge controllers, protection components and other energy products from established brands.
As energy needs change, existing systems can often be upgraded. We help customers expand their battery capacity, inverter capacity or solar generation where technically appropriate.
We provide maintenance and technical services to help customers keep their systems operating properly.
We design and install systems for businesses and organisations that require dependable power for their operations.
Through our training initiatives and Solar Academy, we equip individuals with practical knowledge and skills to participate in the growing renewable energy industry.
With an operating history dating back to 2014 and more than 5,000 installations, our experience is built on real projects and real customers.
We don't believe in one-size-fits-all solar systems. Our solutions are designed around the customer's actual energy requirements.
We work with established brands and provide access to a broad range of solar and energy products.
Customers can visit our physical locations and Solarite Mall to access products and speak with our team.
Our relationship with customers does not end when an installation is completed. We provide maintenance, technical support and upgrade solutions as their needs evolve.
We believe informed customers make better energy decisions. That is why education is an important part of what we do.
At Cornerstone Solar, we understand that investing in a solar system is a significant decision.
Whether it is a family looking for dependable electricity, a business trying to reduce generator dependence, a hotel protecting its operations or an organisation seeking a more sustainable energy solution, we understand that our customers are trusting us with something important.
That trust is something we do not take lightly.
We are committed to combining quality products, proper system design, professional installation, safety, customer education and dependable support to deliver energy solutions that are built for real-life use.
