Sunshine not just for scenic views

Electricity bills keep climbing, and while load-shedding has eased, municipal and Eskom tariffs continue to rise. In response, sectional title schemes across Johannesburg and Tshwane are embracing solar power purchase agreements (PPAs) to curb escalating costs. These agreements install solar panels on communal roofs at no upfront cost and sell clean power back to residents and businesses at a fixed, reduced rate.

How sectional title solar PPAs work for complexes

In a typical 10-year sectional title solar PPA, the installer funds and maintains the entire solar infrastructure, panels, inverters, and meters, meaning the complex simply pays for the clean electricity produced without any initial capital outlay. The system remains the property of the installer throughout, while the body corporate benefits immediately from lower electricity costs and zero maintenance worries.

Metrowatt SPS: smart, efficient solar solutions

A standout in this space is Metrowatt’s Smart Power Subscription (SPS) system. Going beyond basic solar, Metrowatt fits smart switches to high-energy appliances like geysers and pool pumps. These devices activate during solar peak production, increasing solar self-consumption from around 30% up to nearly 50% and maximising savings.

Real‑world wins in Joburg and Tshwane

A large Edenvale complex with 112 units now derives 55% of its power from solar energy, saving approximately R275,000 annually.
A mixed-use complex in Johannesburg CBD taps into 42% solar power, reducing electricity costs by R105,000 every year.

Pricing that makes economic sense

One Tshwane scheme was quoted R1.97 per kWh, significantly lower than the municipal benchmark of R3.42 per kWh for the first 100 kWh. PPA rates are typically capped at around 6% annual increases, well below Eskom’s frequent double-digit tariff hikes.

What makes solar PPAs a compelling option?

Before installation, installers perform detailed feasibility studies, assessing consumption patterns and roof layouts, and installing bulk meters if needed. Once operational, complexes enjoy clean, reliable solar power with no maintenance concerns; the PPA provider carries all responsibilities. At contract end, the body corporate can renew the agreement or opt to remove the system at no additional cost.

Financial and environmental ripple effects

Savings on communal electricity allow bodies corporate to redirect funds towards maintenance, upgrades, or even levy reductions. Beyond financial benefits, complexes bolster their public image by cutting carbon footprints and promoting sustainable living, helping Joburg and Tshwane build greener, more resilient communities.
