Older South African homes carry real charm and architectural value, but their thick walls,
single glazing and patchwork wiring make a renewable energy retrofit genuinely tricky. This
article walks through how to integrate rooftop solar PV with lithium battery storage and
hydronic underfloor heating in heritage, double-storey or pre-2000 homes, without compromising
the building's character.
Filter by topic to find what matters to you, from off-grid living and hybrid system design to underfloor heating economics and load shedding resilience.
As environmental concerns and energy efficiency take centre stage, homeowners are turning to innovative solutions for sustainable living, one of which is Passive House design.
As load shedding continues, individuals and communities are exploring off-grid solar, not just to cope, but to embrace an independent, eco-friendly lifestyle.
An exciting blend of innovation and environmental responsibility is shaking up how we secure homes and industrial spaces, picture a fence powered by the sun.
Synergy Energy offers water (hydronic) underfloor heating that distributes warmth evenly across the whole floor, a more efficient way to heat your home or business.
South Africa has a thriving solar sector, with manufacturers, installers, financing options and expert consultants all part of a diverse, growing landscape.
Underfloor heating provides energy-efficient, even heat distribution compared to radiators, here's what the installation involves and the factors to weigh.

Are the articles relevant outside South Africa?
While the technical principles in our articles apply broadly, sizing recommendations, financial modelling, regulatory references (SAPVIA, PV GreenCard, NRS 097-2-3), tariff calculations and product availability are all written for the South African market. International readers are welcome, but readers in other countries should adjust assumptions for local grid conditions, climate and pricing.

What we do
One team, six connected energy solutions.
We design every home or business as one integrated energy system, solar, storage, charging and heating working together, rather than as a collection of separate appliances.
Tesla Powerwall 3 installation
All-in-one 13.5 kWh battery with built-in 11.5 kW solar inverter, ideal for load shedding backup and daily solar self-consumption. Approved Tesla installers nationally.
Grid-tied, hybrid and off-grid solar generation using Tier-1 panels and Sunsynk, Deye, Victron or Fronius inverters, sized around measured consumption.
Home and workplace AC chargers from 7.4 kW single-phase through 22 kW three-phase, integrated with your solar system for zero-cost charging on sunny days.
Water-based underfloor heating with heat-pump or gas boiler heat sources. Low running cost, whisper-quiet, and ideal for new builds and major renovations.
Reading is one thing, designing a system that fits your home, your budget and your Eskom bill is another. Book a free consultation with one of our engineers. We'll review your usage, measure your roof, and hand you a fully itemised system design, no pressure, no obligation. Branches in Centurion, Cape Town and Polokwane, with national coverage.
