Welcome to 3ESL
We look forward to a mutually beneficial partnership and an exciting journey with you.
We are a team of engineers with considerable hands-on experience in renewable energy strategy and policy advice, solar PV and energy efficiency project conceptualisation, engineering, construction, operation and maintenance.
Our mission at 3ESL is to promote modern and clean energy technologies in West Africa and beyond. We do this by minimising — or eliminating altogether — the concerns of solar PV and energy efficiency service providers, project developers and financiers, as well as those of the customers those groups serve. Through our strategic business partnerships we deliver cutting-edge solutions to meet the unique needs of our clients.
Our passion for innovation and our dedication to upholding quality standards assure peace of mind and optimum return on investment for our clients.
Licensed & registered
The installation licence matters more than it sounds: an unlicensed installer cannot get a net-meter application through, whatever they tell you.

How we think about it
A large share of what we do is independent: design reviews, testing and commissioning, technical due diligence for lenders, Owner's Engineer roles. It is difficult to cut a corner on your own installs when half your work is finding other people's.
Load profiling with Class A certified power analysers. Thermal drone inspection. Design verification run as an actual calculation — string voltage at the coldest morning, conductor sizing and volt drop, protection coordination, DC/AC ratio, roof fit — not as a rule of thumb.
Signed electrical test records, a commissioning report, a bill of materials naming makes and models, and a maintenance schedule. Five years later, when a warranty claim needs evidence, it is there.
Our process
In that order, always. The step people want to skip is the first one, and it is the one everything else depends on.
We visit, measure and record: roof area and orientation, shading, the existing distribution board, and what your loads really are. Everything downstream is built on this, so it is done properly or not at all.
Your consumption becomes a design: array size, inverter rating, storage capacity and the string configuration behind them. You see the assumptions, not just the answer.
The design is checked against the standards before anybody is asked to pay for it — string voltages at the coldest morning, conductor sizing and volt drop, protection coordination, DC/AC ratio, roof fit. Then a quote built from a real bill of materials.
Installation to the drawings, commissioning with instrument-recorded test results, and a maintenance schedule that keeps the output where the design said it would be.
Partners
We are not tied to a single manufacturer. Component selection is part of the design work, decided after the site visit rather than before it.
Sunsynk
Bidirectional hybrid inverters and LiFePO4 storage — the backbone of most of our residential and commercial systems.
Dyness
LiFePO4 battery storage for residential and commercial systems.
Jinko Solar
Tier-1 photovoltaic modules from one of the world's largest manufacturers.
Circutor
European energy efficiency, power quality and energy management equipment.
Training
Manufacturers ask us to run their installer training programmes in Ghana. It is the clearest evidence we can offer that we know these products properly — and it raises the standard of every system in the market, including the ones we did not install.
Whether it is a home, a factory roof or a portfolio you are lending against.
