Lower, more predictable costs
Compare the proposed service charge with your current tariff and model how each may change over the contract period.
The business case
One energy plan, from analysis to ongoing support
Instead of viewing equipment, maintenance and energy supply as separate decisions, the service brings them into one measured plan. The aim is to reduce grid exposure, improve cost visibility and keep the installed system performing over time.
Power when the business needs it
Solar generation and battery storage can be configured around daytime demand, peak periods and continuity requirements.
Operations and maintenance
A managed structure can include monitoring, planned maintenance, fault response and performance reviews through the agreed term.
Clear risk allocation
Equipment warranties, insurance responsibilities and performance obligations are documented before contracting.
Illustrative commercial scenario
What a tailored proposal can make visible
This example, adapted from a commercial assessment, shows the level of information a decision-maker can expect. It is not a quotation or a prediction for another site.
150 kWp
Solar PV
250 kWh
Battery storage
312,075 kWh
Annual generation
R2.6m
10-year estimated saving
The model compares before and after
- Twelve months of electricity consumption and effective utility tariffs
- Expected solar production and battery use across operating periods
- Monthly and annual energy-cost comparison
- Tariff escalation and contract-charge assumptions
- Maintenance, warranty, insurance and performance responsibilities
- Estimated savings over the proposed term
How it works
A clear path from utility bills to an operating system
01
Understand
Review electricity bills, operating profile, site constraints and business objectives.
02
Assess
Complete the technical, tariff, yield, storage and commercial assessment.
03
Propose
Present the system concept, forecast outcomes, assumptions, responsibilities and contracting options.
04
Deliver
Complete final design, approvals, procurement, installation, testing and commissioning.
05
Support
Monitor performance and provide the maintenance and reporting agreed in the contract.
What we need for your first assessment
- Recent electricity bills, preferably covering 12 months
- Site address and normal operating hours
- Critical loads and the impact of power interruptions
- Available roof, carport or ground area
- Expansion plans or expected changes in energy demand
Important commercial conditions
Every site is different. Savings, generation, tariffs, service charges and equipment sizes are confirmed only after technical and commercial assessment. No-upfront-capital structures are subject to project suitability, credit approval and final contracts. Insurance, warranties, maintenance and escalation terms apply only where expressly included in the signed agreement.
Stonegrid Engineering is not a lender or credit provider and does not provide, arrange, underwrite or guarantee finance or approval.
