Commercial solar explained simply: it uses rooftop or ground-mounted panels to generate electricity for a business, reducing the amount bought from the grid during daylight hours. Unused energy may be exported, while batteries can store solar power for later use, depending on the system and site. Costs, savings and payback depend on factors such as electricity consumption, tariffs, roof space, system size and installation conditions. An accredited solar installer can assess the property, and businesses should check current incentives and requirements with the relevant government department and energy retailer.
