Solar installation in Constantia and the Southern Suburbs
First Energy Solar Solutions – engineer-led solar installers, Western Cape
First Energy designs and installs residential and commercial solar across Constantia, Bishopscourt, Tokai, Bergvliet, Newlands, Claremont and Kenilworth. Larger properties, higher loads and stricter aesthetics make Southern Suburbs installations engineering-led – which is what we do.
Certified installer for Tesla Powerwall and Fox ESS – one of a small number of Western Cape installers certified by both, alongside our AREP registration and Standard Bank and Nedbank approvals.
Why Constantia homes and businesses do well on solar
Constantia’s big plots and mature trees are lovely to live with and awkward for solar: shading from oaks and pines changes through the day and the year, so a layout that looks fine in July can lose a quarter of its output in January. We model shading before we quote and, where it matters, use panel-level optimisation. Loads are typically high – pool pumps, boreholes, underfloor heating, multiple geysers and home offices – so systems here are often 8–12 kWp with 10–20 kWh of storage, and our two Bishopscourt installations are 36 kW and 50 kW. Many homes sit on estates or in heritage-sensitive streets with rules on visible panels; we design for the least visible roof planes first.

What it costs in Constantia
Installed prices are the same across our Western Cape service area – see the 2026 cost guide – but roof type, DB board condition and cable runs affect the final quote, which is why every Constantia quote follows an engineer’s site visit. Our packages start from R55,574 (backup only) and R92,017 for a 3.3 kWp hybrid system, with rent-to-own plans over 3, 4 or 5 years. Every system carries a 25-year performance warranty on the panels, 10 years on the inverter, 6,000 cycles on the battery and 3 years on our workmanship.
Registration and feed-in in Constantia
This area is in the City of Cape Town’s supply area, so your system is registered online through the City’s e-Services platform, must use a City-approved inverter, and – once an AMI meter is fitted and your account moves to the Home User tariff – earns about R1.53 per exported unit under the 2026/27 feed-in tariff, with the City paying out cash once your account is fully offset (Cash for Power). We prepare and submit the application, supply the engineering sign-off and follow it through to written authorisation. How SSEG registration works.

Frequently asked questions
How much does solar cost in Constantia?
Southern Suburbs homes usually need larger systems than average. Expect roughly R92,000 for a 3.3 kWp hybrid starter system, R155,000–R215,000 for the 5.5–7.7 kWp systems most Constantia homes choose, and custom pricing above 10 kWp. Your free savings report gives the exact size for your usage.
Do I need permission to install solar in Constantia?
Yes – every solar or battery system in the City of Cape Town’s supply area must be authorised as an SSEG installation before it is switched on. Estates and heritage areas may add their own aesthetic approval. We handle both.
How long does it take?
The site visit and quote take 3–5 working days, municipal authorisation about 2–4 weeks (which runs while we order equipment), and a typical home installation is done in one to two days.
Do you install without a battery?
Yes. Grid-tied systems without storage are the most cost-effective way to cut a daytime-heavy bill; a battery adds evening self-consumption and outage cover.
