The Real Cost of Depending on the Grid

Most people think about their electricity bill in terms of what they pay each month. But the more useful question is what that bill will look like in five or ten years if nothing changes.

Businesses & Commercial

Businesses face this pressure acutely. Many have turned to diesel generators as a stopgap, but diesel is not cheap. Running a generator through load shedding adds up fast—easily tens of thousands of rand a year on fuel alone. Solar with battery backup eliminates that recurring cost and replaces unpredictable fuel spend with a fixed, once-off capital investment.

Residential Homes

A solar system that offsets most of your electricity usage locks in a large portion of your energy costs at today's price, shielding you from future increases. In the Western Cape, where sunshine hours are consistently high throughout the year, systems here produce energy reliably and the financial returns are among the strongest in the country.

Our Solar Power Services

We offer a full range of solar services for residential, commercial and industrial clients. Each service below has its own dedicated page with more detail, pricing guidance and FAQs:

Solar Installation

A complete solar installation includes panels, inverter, battery storage and all electrical connections. We handle the design from start to finish.

See our solar installation service →

Repair & Maintenance

Existing solar systems need attention over time. Panels can be damaged or inverters fail. We diagnose faults, repair, and conduct maintenance.

See our repair and maintenance service →

Battery Storage

Battery storage turns a solar system into a load shedding solution. We install storage as part of a new system or an addition to an existing one.

See our battery storage service →

Inverter Installation

The inverter is the core of any system. Upgrading to a newer model improves a system's performance and reliability significantly.

See our inverter installation service →

Off-Grid Solar

Not every property is connected to the municipal grid. We design and install off-grid systems sized to cover your full independent energy needs.

Commercial solar installation

Real Solar Projects in the Helderberg and Boland

We currently have a 100kW commercial solar system underway at Val De Vie Estate in Stellenbosch. This is a large-scale installation designed to significantly reduce the estate's electricity costs and provide reliable power during load shedding. It is one of a growing number of commercial and estate solar projects we have completed across the Western Cape.

We also install residential solar systems across Somerset West, Strand, Gordon's Bay, Franschhoek, Paarl and Durbanville. From a battery backup setup in a Parel Vallei townhouse to a full hybrid system on a working farm near Durbanville, each project is designed around the specific property and the client's actual energy needs.

Frequently Asked Questions

Everything you need to know about working with EAR Engineering.

The starting point is your current electricity bill and how it has changed over the past few years. If your costs have been climbing and you expect them to keep climbing, solar gives you a way to lock in a significant portion of your energy costs at a fixed capital investment rather than paying an ever-increasing tariff indefinitely. The Western Cape's sunshine hours make systems here particularly effective, and a site visit gives us the information we need to give you a realistic picture of what a system would cost and what it would save over time.
A hybrid system is connected to the municipal grid and uses solar panels and batteries to reduce your grid reliance and provide backup during outages. An off-grid system has no grid connection at all and relies entirely on solar and battery storage to meet your energy needs. Hybrid systems suit most homes and businesses. Off-grid is typically for rural or remote properties where grid connection is impractical or unavailable.
Yes. If you already have solar panels but no battery storage, adding batteries is a straightforward upgrade in most cases. We assess your existing system, check that the inverter is compatible, and install the batteries correctly. This is one of the most common requests we receive from clients who installed solar before load shedding became as severe as it is now.
Quality solar panels typically carry a 10-year product warranty and a 25-year performance guarantee. Inverters have a shorter lifespan, typically 10 to 15 years, and batteries vary depending on the technology and how heavily they are cycled. A well-maintained system should serve you reliably for 20 to 25 years.
Yes. We install commercial solar systems up to 100kW for offices, retail properties, guesthouses, wine estates, farms and other commercial clients. Our current project at Val De Vie Estate in Stellenbosch is an example of the scale we work at on the commercial side.
Call us. We carry out fault diagnosis on solar systems and can identify whether the issue is with the panels, the inverter, the batteries or the electrical connections. Most faults can be diagnosed and repaired in a single visit.
Yes. We carry out repairs, maintenance and upgrades on solar systems regardless of who originally installed them. If your system is underperforming or you are not sure it was installed correctly, we can assess it and tell you what needs attention.
We cover Somerset West, Strand, Gordon's Bay, Stellenbosch, Franschhoek, Paarl, Durbanville and Cape Town. Our base is in Somerset West so our response times across the Helderberg are especially fast.
Call us on 021 855 4462 or send us a message. We will ask a few questions about your property and energy needs, arrange a site visit, and come back to you with a clear recommendation and a quote once we have seen what is involved.
