About Us

Engineers first, since 1996

A Sierra Leonean company built by certified electronics and communications engineers, delivering sophisticated solutions in a straightforward, user-friendly way.

Our story

Nearly three decades of connecting Sierra Leone

Sigma Communications Ltd. was registered in 1996 in Sierra Leone, West Africa, by a group of electronics and communications engineers who set out to deliver sophisticated radio and energy solutions in an easy, user-friendly way.

Over the years we've built a strong network of partnerships with the world's leading radio communications, satellite communications, renewable energy, switchboard, access control and CCTV equipment manufacturers. Today our team of qualified engineers has supplied humanitarian organisations, government bodies, GSM operators and private sector clients with professional, high-quality solutions at affordable prices — bringing communications and clean energy to even the most challenging remote areas in the provinces of Sierra Leone.

We're in business to provide quality, cost-focused equipment and services that maintain our role as Sierra Leone's trusted company for radio communication and clean energy.

Our commitment

Quality, warranty, fair pricing

We are committed to providing high-quality solutions, covered by warranties, at reasonable prices that encourage the local market — particularly in clean energy — to grow while keeping Sierra Leone's environment clean and free of pollution.

Why solar energy

Why we believe in the sun

Relying on coal, oil and natural gas threatens the future with pollution, climate change and the social strain of diminishing fuel supplies. We help our clients thrive on the planet's abundant, renewable supply of solar energy instead.

No monthly bills

Solar panels are extremely reliable, with no moving parts to replace. Most systems run for thousands of hours with little to no maintenance.

Environmentally friendly

Unlike fossil fuels, solar cells release no greenhouse gases, carcinogens or carbon dioxide into the air — and sunlight never runs out.

Works anywhere

Solar energy can be installed in a remote village, a rural clinic, an island, or the top of a hill — wherever the grid doesn't reach.
