Commercial and industrial solar projects are capital investments that should be evaluated like any other. These are the questions a robust feasibility study answers.
Is the design based on measured data?
Ask whether the system was sized from interval load logging or from estimates. Measured base load, peak demand and night-time consumption are essential for correct battery and inverter sizing.
What does the financial model include?
A credible model shows:
- Total capital cost, including engineering, structural work and commissioning
- Diesel displaced (litres) and grid energy avoided (kWh)
- Fuel price and tariff escalation assumptions — with sensitivity analysis
- Operations and maintenance costs
- Battery and inverter replacement reserves
- Payback period, cumulative cash flow and levelised cost of energy (LCOE)
How will the system integrate with existing assets?
Generators, changeover panels, power-factor correction and critical loads must be considered. Poor integration can cause nuisance trips or limit savings.
What happens after commissioning?
Ask about monitoring, performance reporting, preventive maintenance schedules, response times and warranty administration.
Is the roof or site suitable?
Structural capacity, roof condition and remaining roof life should be assessed before mounting a 20–25 year asset.
