Pricing for Independent Solar, Battery & Gas Advisory
Structured, independent technical advisory for South African businesses evaluating solar, battery, and gas investments. Our pricing is designed to give decision-makers commercial clarity while allowing scope to be matched to the complexity of each review.
Every engagement is focused on reducing specification risk, exposing hidden lifecycle costs, and helping you commit capital with greater confidence.
Independent, Fixed-Fee Advisory
We do not sell hardware, and our fee never changes based on your choice of system or installer.
Built for SA Operating Realities
Models based on actual Eskom load shedding stages and tariff structures.
Technical Review Before Capital Commitment
Stop specification errors before the first panel is bolted down.
Structured Deliverables
Actionable data and reports, not vague opinions or verbal summaries.
How It Works
How Our Pricing Works
Our services are structured around the level of technical and financial analysis required. Simpler quotation reviews across solar, battery, or gas can often be priced at a defined starting fee, while larger or more complex commercial cases may require a scoped confirmation before work begins.
We do this to ensure pricing remains fair, commercially realistic, and aligned with the actual review effort required for your specific site.
Our Pricing Commitments
- Clear starting prices for standard advisory work.
- Scope confirmation and fixed-fee quotes before any work begins.
- Fixed advisory fees, never a percentage of your system cost.
- Customised pricing for large-scale or multi-site commercial reviews.

Pricing Factors
What Can Affect Final Pricing?
Final pricing may vary depending on the complexity of the review and the quality of the information provided upfront.
Quantity
Number of quotations to be audited and compared.
Complexity
System size (kWp) and technical architecture -- e.g. hybrid vs. grid-tied.
Depth
Whether battery chemistry and inverter surge analysis are required.
Financials
If detailed ROI, payback, or lifecycle modelling is needed.
Geography
Multi-property or multi-site scope requirements.
Speed
Urgent turnaround requirements for expiring quotations.
Where the scope is straightforward, we confirm the fee quickly. Where it is complex, we provide a clear quotation before work begins -- no surprises.

FAQ
Pricing & Advisory FAQs
Common questions about how our pricing and engagement structure works.
We provide "starting prices" for standard reviews. More complex cases are quoted individually to ensure you only pay for the depth of analysis you actually need.
Because our independence is paramount. Percentage-based fees create an incentive to recommend more expensive systems. Our fixed-fee model ensures our advice is 100% objective.
Our core advisory packages are strictly fixed-fee, so we have zero incentive to artificially inflate system sizes or steer you toward any particular brand. If we connect you with a vetted installation or gas supply partner for execution, any commercial introduction arrangement that exists is explicitly disclosed to you in writing upfront — radical transparency, not blanket denial.
Yes. Our Comparative Quote Review is specifically designed to help you choose between multiple competing proposals with a structured side-by-side technical analysis.
Simply contact us with a brief description of your project and we will recommend the most cost-effective package for your situation.
