Epping – Factory Installation

Project Manager: Adam

Product: Commercial Savings

Specification:

2x 100kW Canadian Solar inverters

314x 590W solar panels (185kWp total)

Our client in Epping operates a factory with consistently high daytime energy demand but very little usage at night. This made their site an ideal candidate for a solar solution designed to directly offset daytime electricity costs.

We installed two 100kW Canadian Solar inverters paired with 314 high-efficiency 590W panels, giving the system a total capacity of 185kWp. The inverters were intentionally sized slightly larger than the current panel array, leaving room for future expansion as the client’s energy needs grow.

The setup is perfectly matched to the factory’s load profile, generating power when it’s needed most and significantly reducing daytime electricity bills. With this design, the client not only benefits from immediate savings but also has the flexibility to scale up their solar capacity over time.

Westlake – Factory Installation

Project Manager: Adam

Product: Commercial Savings

Specification:

3x 50kW Canadian Solar inverters

300x 580W solar panels (174kWp total)

This factory in Westlake was looking for a way to bring down its high electricity costs. With energy being a major expense in daily operations, a large-scale solar system provided the most effective solution.

We installed three 50kW Canadian Solar inverters alongside 300 high-efficiency 580W panels, giving the system a total capacity of 174kWp. This allows the factory to offset a significant portion of its electricity bill through solar production.

Any excess energy generated is exported back into the city’s grid, ensuring the client gets the maximum return on their investment. The result is a system that delivers substantial cost savings while also contributing clean power to the wider community.

Hout Bay – Cape Town

Choosing an installer is not only about price. It is also about pride and experience. We have re-installed this system.

When our client reached out, they were dealing with a system that was partially operational from an installer that had since closed. They needed a reliable solar provider to assess, optimize, and improve the system. We thoroughly evaluated every angle of the roof and assessed the equipment to ensure we could offer a solution that would not only meet but exceed expectations.
We upgraded their existing single-phase system to a powerful three-phase setup, enabling us to provide full-house backup—giving them complete peace of mind. Additionally, we redesigned and optimized the 12kW panel layout to maximize efficiency, ensuring the system delivers reliable energy throughout the day. This solution boosts both sustainability and cost savings for our client.
At oneSolar, we don't just provide installations—we offer scalable, long-lasting solutions designed to evolve with your energy needs. And with our next-level support, you can trust that your system is in safe hands for the long haul.

Gardens - Cape Town

This system was carefully designed to meet the clients need for an intelligent solution that not only operates on a three-phase configuration but also feeds excess power back into the grid.

We chose Victron for its efficiency and versatility in solar applications. The installation includes three 10KVA Victron inverters, a Victron MPPT charge controller, a PV Fronius inverter, 42.9kWh of battery capacity, and 38 panels rated at 410W each.

Now, the client is running entirely on solar power—with the panels covering his energy loads and charging his battery during the day so he can rely on stored energy in the evening.

Franschhoek – Wine Farm & Residence

This wine farm and residential home in Franschhoek needed a solar solution to reduce electricity costs and provide backup power during outages. We installed a system that allows the estate to make the most of solar energy while keeping essential operations running when the grid goes down.

The setup includes a 50kW Deye inverter, 50kWp of solar panels, and 120kWh of high-voltage battery storage. While the system doesn’t power the entire estate, it significantly reduces reliance on the grid and ensures that critical loads remain operational during outages. By balancing solar production, battery storage, and grid support, the estate benefits from lower electricity costs and improved energy security.

This installation offers a practical and sustainable energy solution, helping the estate manage its power needs more efficiently while maintaining reliable backup when it’s needed most.

Clifton – Cape Town

Our client was looking for an effective way to raise their pool temperature to fend off those chilly Cape Town weather conditions.

With this system, the cold pool water is diverted through the Pool Solar Heating panels, which are mounted in a sunny position on the roof. The water is returned to the swimming pool 6–12 degrees warmer. The circulation process continues throughout the day, which in turn heats the pool water to a more comfortable temperature. The existing pool pump is used, so no additional costs are incurred.

It is important to note that these panels do require sunlight to effectively raise the pool water temperature.

Courtyard - Bellville

Our client, a student hostel offering compact apartments, aimed to drastically cut their electricity costs while feeding any surplus energy back into the grid. By using two Fronius inverters, each with two MPPTs, we maximised the use of both East and West-facing roof spaces. This setup ensures a balanced energy distribution throughout the day.

Are you a property owner with a sunny roof? Make the most of it! This solution not only enhances your return on investment but also provides immediate tax benefits.

The council supplies a bulk meter, enabling landlords to reduce their bulk electricity expenses. This strategy transforms shared roof spaces into valuable assets, delivering significant savings and additional perks.

Hout Bay – Cape Town

We installed a 6kW solar panel system for our client in 2023 who was focused on maximising their renewable energy output, this system generated an average of 24kWh per day. Understanding their goal for even greater energy independence, we recently upgraded the system by adding an additional 5kW of panels. This enhancement boosted the total capacity to 11kW, producing an impressive average of 44kWh per day. As a result, the client’s reliance on grid electricity has been significantly reduced, leading to substantial cost savings and a smaller carbon footprint. This expanded solar setup not only fulfils their current energy needs but also ensures long-term energy security and sustainability.
