Refrigeration Efficiency. Guaranteed Savings. Zero Upfront.
Turn your refrigeration and cooling systems into guaranteed money-savers — with no upfront capital.
Smart VSD retrofits, advanced controls, real-time metering, and intelligent solar integration. Pay only from the energy you save through our Cooling-as-a-Service (CaaS) or shared-savings model.
Proven 30–40% energy reductions in South African supermarkets, butcheries, and food processors. We fund the upgrades. We monitor and optimise 24/7. You enjoy lower bills and reliable cooling.
ABOUT SOLAR STITCH
We're a team of energy professionals — electrical engineers, electronic engineers, and seasoned business leaders — with over 20 years of experience across refrigeration controls, VSDs, metering, and energy management.
We spotted a problem: Most businesses waste thousands every month on inefficient refrigeration and air conditioning. Traditional solar companies ignore this. We don't.
Our focus is simple: Help South African businesses cut energy costs through guaranteed, performance-based savings — not one-off installations. We measure the waste, fund the upgrades, and optimise continuously so savings don't fade over time.
We're ABB-trained, Bitzer-certified metering experts who guarantee savings through rigorous Measurement & Verification. We're also honest — we'll tell you if you don't need something, and we'll prioritise your bottom line.
Refrigeration Intelligence & Optimisation
VSD retrofits on compressors (Bitzer/ABB), advanced controls, and setpoint optimisation. We turn inefficient cooling into high-performance, low-cost assets — the foundation for performance-guaranteed upgrades.
Smart Metering & Continuous Monitoring
Sub-metering and cloud dashboard for real-time visibility, predictive maintenance, and automated optimisation. Powered by our technology partner Phy Engineering for advanced controls and software integration.
Financed Savings Solutions
We fund the upgrades. You pay a portion of the verified electricity savings (typically 30–40% reduction) or a fixed fee for reliable cooling performance. No large capex. Measurable results guaranteed via independent M&V.
Solar Value Stacking
Intelligently route excess solar PV to cooling loads for even deeper savings and energy security. Solar as an enhancer for refrigeration efficiency — not a standalone product.
Refrigeration Efficiency. Guaranteed Savings. Zero Upfront.
COOLSTITCH CaaS
Cooling-as-a-Service — Efficiency Without Capital Risk
Free Savings Assessment
We audit your refrigeration loads and quantify waste. No obligation, no cost.
Funded Retrofit
VSDs, smart controls, metering, and optional solar integration. We finance the upgrades.
Continuous Optimisation
Our cloud platform monitors performance, predicts issues, and auto-adjusts for maximum savings.
Share the Benefits
You enjoy lower bills and reliable cooling. We recover our investment from a share of verified savings — typically 40–60% of savings over a 3–7 year term. After the contract, 100% of savings are yours.
TYPICAL RESULTS
WHAT OUR CLIENTS SAY
“Our electricity bill dropped by 40% after the VSD retrofit. We didn't pay anything upfront — the savings paid for everything. The monitoring dashboard lets us see exactly where every rand goes.”
“Load shedding used to cost us thousands in spoiled stock. Since the Solar Stitch team optimised our system, our refrigeration runs through every outage. Zero stock loss in six months.”
“They told us honestly that we didn't need a full solar system — just a compressor retrofit and better controls. That saved us from overspending and we still got a 35% reduction in cooling costs.”
PROVEN RESULTS
Real savings from South African businesses using our VSD retrofits, smart controls, and shared-savings model
Western Cape Supermarket
Refrigeration energy reduction
VSD retrofit on walk-in freezer and cold room compressors with ongoing optimisation under a shared-savings agreement. Client paid nothing upfront and now benefits from continuous monitoring and adjustment.
Butchery Chain — Cape Town
Monthly electricity bill reduction
Achieved through a VSD retrofit and optimised system that continues delivering savings. Advanced metering provides real-time visibility into energy consumption and cooling performance.
Restaurant Group
Load-shedding impact on operations
Smart controls and solar value stacking ensured refrigeration systems continued running through load-shedding schedules. Stock loss eliminated. Operations uninterrupted.
Our CaaS model has delivered 30%+ cost-per-cooling-hour reductions across retail and dairy operations. Solar Stitch combines specialised refrigeration expertise with performance-guaranteed savings that generic solar companies simply cannot match.
Eligible for green finance support and aligned with South African efficiency opportunities. Our model supports IDC ESCO programme requirements and GreenCape energy services priorities.
