Build
Commercial solar and battery installation, built to the model.
Solar PV, battery storage and the electrical infrastructure behind them — engineered, installed and commissioned by the same team that will operate the asset for the next 25 years. Over 10 MW installed across 40+ projects, most of it in Johannesburg, Pretoria and wider Gauteng.
Who this is for
Sites where energy is an operating cost, not a line item
Our build work is concentrated in industrial parks, manufacturing plants and retail centres — sites with daytime load, meaningful roof area, and a real cost attached to every outage. If your electricity bill is a number the board discusses, this is the scale we build at.
What's included
One contractor, the whole installation
No split responsibility between a solar installer, an electrician and a battery vendor. Focal delivers the complete system and signs for all of it.
Commercial solar PV
Rooftop solar installations engineered for commercial and industrial buildings — structural loading, wind zones and roof condition assessed before a single mounting rail goes down.
Battery storage
Commercial battery storage sized against your load profile and outage exposure — for load shedding continuity, peak shaving or shifting solar energy into evening consumption.
Electrical infrastructure
Upgrades to distribution boards, cabling, protection and metering where the existing installation can't support the new system. Done once, documented, and built to be maintained.
Testing & commissioning
Every string, inverter and protection device is tested against the design before energisation. Commissioning results become the performance baseline the asset is measured against for its operating life.
Compliance & handover
Statutory electrical compliance documentation, as-built drawings and O&M manuals handed over at completion — the paper trail your insurers, auditors and future engineers will ask for.
How it works
From approved design to energised asset
Detailed engineering
The approved feasibility design is developed into construction drawings, equipment schedules and a build programme agreed with your operations team.
Procurement & construction
Equipment is procured to specification and installed by our teams. Work around live operations is planned so your site keeps running.
Grid connection & energisation
Utility inspections, protection settings and the SSEG sign-off are completed before the system is switched on — legally and safely.
Commissioning & handover
Measured commissioning results are checked against the model, monitoring is brought online, and the asset moves into 24/7 operations.
Built and measured
Our largest published build: 778 kWp in Pretoria
Hermanstad Industrial is a 778 kWp manufacturing installation that produced 1,245 MWh in its first year — R2.34 million in savings at a R1.88/kWh blended tariff, a 4-year payback and 1,121 tonnes of CO₂ avoided annually. Every number is measured, not projected.
Common questions
Installation FAQs
Where do you install commercial solar systems?
Most of our fleet is in Gauteng — Johannesburg and Pretoria in particular — with 40+ completed projects and over 10 MW installed. We assess commercial sites across South Africa.
Will construction disrupt our operations?
Most of the installation happens on the roof and in plant rooms without affecting daily operations. The electrical tie-in requires a planned shutdown, which we schedule with your team — typically outside operating hours.
Do we need battery storage, or is solar enough?
It depends on your load profile and what outages cost you. Solar alone cuts energy cost; batteries add continuity through load shedding and can shift solar energy into evening use. We model both against your interval data rather than defaulting to either answer.
What size systems do you build?
Our published case studies range from 53 kWp to 778 kWp, across industrial, manufacturing and retail sites. System size is an output of your consumption data and roof area, not a starting point.
Who is responsible for the system after handover?
We are. Focal designs, builds and then operates the asset under long-term agreements — 24/7 remote monitoring, maintenance and monthly performance reports. The builder and the operator being the same company is deliberate: there is no one else to blame if performance slips.
