ABOUT SA SOLAR
SA Solar (SAS) was formed through the strategic partnership of Quest Group and Sage Electrical Systems, two businesses with deep roots in South African renewable energy, united under a single focused brand.
Proudly South African · SA Solar is part of SAS Energy Holdings (Pty) Ltd
01 / OUR STORY
SA Solar did not start from nothing. It started from two established South African businesses, each with a body of completed work behind it, choosing to operate as one.
Parent business 01
Quest Group brings extensive experience across residential, commercial, industrial, agricultural, mining and enterprise-scale renewable energy projects: the breadth required to carry a project from feasibility through to commissioning at any scale.
Sectors delivered
Parent business 02
Sage Electrical Systems brings a proven track record of more than 500 successful residential installations: the depth of repetition that teaches a team how to size a home system honestly and finish it properly.
Track record
The combined entity
Together, under the SA Solar brand, we are uniquely positioned to deliver world-class energy solutions across every sector of the market, from individual homeowners to utility-scale developments.
SA Solar operates as part of SAS Energy Holdings (Pty) Ltd, a proudly South African company and Level 4 B-BBEE contributor.
02 / OUR VISION
Be the renewable energy partner that South African homes, businesses, farms and industries can trust for the long term.
South Africa needs reliable, cost-effective, sustainable energy solutions at every level of the market. We exist to provide them, with the technical depth to handle complex commercial and industrial projects, and the craftsmanship and care to do residential work properly.
Our vision is straightforward. Not to be the largest installer in the country, and not to be the cheapest quote on the table, but to be the partner a client keeps calling back, for the second site, the expansion, and the system after that.
03 / OUR SOLUTIONS
Nine solution lines, one engineering team behind all of them. Every one is designed in-house and installed by people who answer for the result.
04 / TO OUR EXISTING CLIENTS
The formation of SA Solar does not change your relationship with us. All existing clients of Quest Group and Sage Electrical Systems can expect full continuity of support, warranty management and service delivery under the SA Solar brand.
The same people. The same standards. One unified team.
05 / OUR VALUES
We design what we install, and we install it right. The drawing, the specification and the finished system are the responsibility of the same team.
We will tell you if solar is not the right fit, or if a smaller system makes more financial sense. A recommendation we cannot defend is not worth making.
We are not here to sell a system and disappear. Monitoring, maintenance and warranty management continue long after handover.
We invest in local skills, local jobs and local energy security. A Level 4 B-BBEE contributor, working on the grid we all depend on.
ONE ENERGY FUTURE
Built on engineering excellence, quality workmanship and long-term client relationships, SA Solar is here to help South Africans achieve energy security, reduce operating costs and build a more sustainable future.
THE SUN, RIGHT NOW
Computed from your own clock. The ray on the left is drawn at the true zenith angle for this instant; the chart on the right is the spectrum that survives the trip down, against the part silicon can actually use. Everything past 1107 nm passes straight through the cell.

THE LINE YOU ARE STANDING ON
The day and night sides of the earth, computed from where the sun is directly overhead at this moment. The tilt of that line against the meridians is the season. The figure of eight is the analemma: where the sun sits at the same clock time every day for a year, and the reason solar noon and clock noon disagree.
Subsolar point from the equation of time and Cooper declination; the terminator is the great circle 90° from it. Recomputes once a minute.
ALREADY IN THE DIARY
A total solar eclipse crosses southern Africa on 25 November 2030, from the Atlantic over Namibia, Botswana, South Africa and Lesotho, leaving the coast near Durban. Every plant inside the shadow ramps down together, which is exactly the correlated event a spread-out fleet normally protects you from.
