A commercial solar comparison should look beyond the panel price, including system size, expected energy production, inverter quality, warranties, monitoring and installer experience. Compare proposals using your business’s electricity usage, tariff structure, demand charges, operating hours, roof condition and local export limits. Check whether incentives such as small-scale technology certificates or other programs may apply, as eligibility depends on system details and current government rules. Ask each installer for itemised pricing, estimated savings and payback assumptions, then have an accountant or energy professional review the figures before deciding.
