Solar Installations Philippi Horticultural Area

An aquifer-fed farming area with a very particular load profile

The Philippi Horticultural Area covers roughly three thousand hectares of the Cape Flats, with sandy soils that let winter rain soak down into the aquifer below. Farms range from small plots of a few hectares to operations of several hundred, and almost all depend on boreholes and pumps for irrigation. That gives the area a distinctive electricity profile: large motors, long irrigation runs during warm, dry months, and cold storage and packing that follow the harvest. Because most of that demand falls in daylight, solar fits naturally, and the savings usually come from replacing grid power during the sunniest hours.

We begin with the facts that matter: your tariff, meter history, pump sizes, three-phase supply and the layout of sheds, packhouses and land. From those we propose a system sized to the real daytime load, not simply the biggest roof area available.

Roofs, ground-mount and the realities of flat sandy land

Many farms have large shed roofs, which are often the simplest and most secure place for panels. Where roofs are small, old or far from the pump, a ground-mount array may be the better choice. The area is flat and open, with little shelter from the wind, so frames and foundations must be engineered for gusts. Soils are sandy, and parts of the area flood seasonally in winter, so we avoid positioning equipment where water collects, raise inverters and distribution boards, and plan cable routes that will not sit in standing water.

Roof-mounted systems near occupied buildings are also easier to protect. Equipment theft and cable theft are genuine concerns for growers, so we discuss secure fixings, enclosures, cable protection and remote monitoring. We cannot make a farm theft-proof, but sensible design lowers the risk and the cost of recovering from it.

Protecting produce when the grid fails

An outage in the middle of irrigation is an inconvenience. An outage at a cold room or packing line can ruin stock. For those circuits, we design battery backup or a hybrid arrangement that keeps refrigeration, lighting, security and communications running, while pumps and heavy equipment remain on the grid or run on solar when conditions allow. Agricultural businesses may also qualify for tax allowances on renewable energy investment, which is something to raise with your accountant. We provide the technical and cost information they will need.
