Our Story

Where deep industry experience meets solar ambition

Deo Solar was founded by Gerhard Farrell, whose background spans the mining, petrochemical, and energy industries — and Jaco Farrell, who brings more than 30 years of hands-on experience across agriculture, construction, and energy.

That combination of sectors isn't accidental. Solar sits at the intersection of all of them — it powers farms, factories, and remote sites under conditions that demand real engineering, not guesswork. We knew the problems from the inside, and we built Deo Solar to solve them properly.

What started as a services business has grown into both an installer and a product developer — designing and manufacturing our own SA-built rail-less mounting brackets, used by EPCs and installers across South Africa and beyond.

Who We Are

Mission, Vision & Values

Everything we do traces back to three words — the same three words in our tagline.

M
Mission

To deliver solar that performs — and lasts.

We provide commercially and industrially focused solar solutions — from full EPC delivery and energy analysis to our own SA-manufactured mounting products — giving clients one trusted partner for every phase of their project.

V
Vision

To be Africa's most trusted solar partner.

We are growing from a South African roots business into a leading solar services and products company across Sub-Saharan Africa — known for technical excellence, honest advice, and systems that work long after commissioning day.

V
Values

Generate. Conserve. Contribute.

Our tagline is our values. We generate clean energy and economic opportunity. We conserve resources through smarter installation methods. And we contribute — to clients, to communities, and to a sustainable South Africa.

The People Behind Deo Solar

Meet the team.

Five people. One shared commitment to getting solar right — from engineering and manufacturing to delivery on site.

Founder

Gerhard Farrell

Managing Director

Gerhard brings a career built across the mining, petrochemical, and energy industries to the helm of Deo Solar. His cross-sector engineering background means he approaches solar not as a sales product, but as an infrastructure investment — one that has to perform under real industrial conditions.

Co-Founder

Jaco Farrell

Co-Founder

With more than 30 years of experience across agriculture, construction, and the energy sector, Jaco brings the practical knowledge that comes from building things in the field — not just designing them. His understanding of how solar integrates with farming operations, structures, and rural infrastructure is invaluable to the projects Deo Solar takes on.

Johan Farrell

Head of Projects

Johan oversees all project delivery at Deo Solar — coordinating site teams, managing timelines, and ensuring every installation meets the standard the engineering drawings call for.

Deacon Pretorius

Sales

Deacon is the first point of contact for most new clients — helping businesses understand their options, navigate system sizes, and find the right Deo Solar solution for their specific situation.

Ross Stubbs

Client Relationship Manager

Ross ensures that clients stay informed and supported at every stage of their project — and well beyond commissioning. He’s the reason our clients come back.

Why Choose Us

We don't just sell solar. We deliver it.

There are many solar companies. Few have built their own product line, trained their own installation crew, and employed B.Eng engineers to design every system they sell.

In-house engineeringEvery system designed by a qualified B.Eng engineer — not a sales configurator
Our own installation crewWe don't subcontract the install out — our team does it, which means we own the quality
SA-made productsOur rail-less mounting brackets are designed and manufactured in South Africa — for SA roof profiles and conditions
Direct accountabilityThe same engineers who design your system oversee its installation — there's no handoff gap, and no one to blame but us if it's wrong
Generate.
We help businesses generate clean, reliable power — reducing their dependence on the grid and cutting the cost of electricity for good.
Conserve.
We conserve resources — through efficient rail-less installation methods, right-sized systems, and products built to last decades, not years.
Contribute.
We contribute to a sustainable South Africa — through local manufacturing, skills development, and solar projects that make a measurable difference.
