Commercial solar can reduce the amount of electricity a business needs to buy from the grid, but the saving is never a one-size-fits-all figure. The result depends on your roof or land, the hours your business operates, your electricity tariff, and how the system is designed.

The strongest commercial solar projects are sized around real demand. A warehouse with daytime loading, refrigeration or office loads may use a large share of its solar generation on site. A factory can often match solar output to production. If a site exports a lot of generation, the value of that exported electricity may be lower than the value of using it directly.

Before investing, ask for a site-led proposal that shows expected generation, self-consumption, export assumptions, annual savings, system size and payback range. It should also explain how roof condition, grid capacity, planning, access and future demand have been considered.

Battery storage, EV charging and flexible operating patterns can change the numbers again. They may help a business use more of its own solar, manage peak demand or charge vehicles when generation is available. The right combination depends on the site, so a useful assessment starts with your interval data and building plans.

The quickest way to get a realistic view is to share your postcode, building type and annual electricity spend. Pinkgroup Renewables can then model the opportunity and show the financial and environmental case in a clear commercial solar proposal.
