Commercial Solar Quotes

A commercial solar quote should go beyond the price of the panels. It should explain the recommended system size, expected solar generation, projected electricity savings, payback period, capital cost, applicable incentives and the assumptions used to calculate the financial return.

It should also account for site-specific requirements such as switchboard capacity, network connection, metering, roof condition and any electrical or structural works that could affect the final project cost.

Sharp EIT assesses these factors before recommending a system so you can understand the complete business case before you commit.

Commercial solar costs vary considerably depending on system size, equipment, roof and site conditions, electrical infrastructure, network requirements and the complexity of the installation.

Larger systems generally achieve a lower cost per kW, but comparing quotes purely on price per kW can be misleading if one proposal excludes network protection, switchboard upgrades, structural works or other project costs.

See our Commercial Solar System Costs & Pricing page for indicative pricing by system size and the factors that can affect the final investment.

The right commercial solar system size depends primarily on how much electricity your business uses during solar-generation hours, rather than simply how much roof space is available.

We analyse your electricity bills and, where available, interval data to understand your daytime load and recommend a system designed to maximise useful solar generation and financial return. Available roof space, future energy demand, network capacity and plans for battery storage or EV charging can also influence the final system size.

Your recent electricity bills are the best starting point. For a more detailed assessment, interval data can show when your business uses electricity throughout the day and help determine how much solar generation could be consumed on site.

We may also consider your operating hours, site address, roof and electrical infrastructure, future expansion plans and whether you're considering battery storage or EV charging.

You don't need to have all of this information before enquiring. We can help identify what is required for the next stage.

Available incentives depend on the size of the commercial solar system, installation date and eligibility requirements. Certificate schemes can reduce the effective cost of eligible projects, while the applicable framework differs depending on system size.

Sharp EIT factors applicable incentives into the financial assessment so you can understand the expected project cost and payback after eligible incentives rather than relying on the headline system price alone.

Yes. Eligible businesses may be able to finance a commercial solar project rather than paying the full capital cost upfront. The appropriate structure depends on the project, business and credit approval.

Sharp EIT offers commercial solar finance options through its finance partners, allowing eligible businesses to compare an upfront CAPEX purchase with financed options as part of the overall business case.

It depends on how and when your business uses electricity. Battery storage can make sense where there is excess daytime solar generation, significant electricity use outside solar-generation hours, demand-charge opportunities or a requirement for greater energy resilience.

For some businesses, solar alone will deliver the stronger financial case. For others, solar and battery storage can work better together. We can model the options against your site's energy profile rather than automatically adding a battery to the proposal.
