A 100 kW system is a commercial installation. It suits a workshop, a warehouse, a retail or medical premises, a club, a school or a farm with three phase supply and a daytime load that runs through the week. With 227 panels across about 454 square metres of roof it produces around 390 to 420 kWh on an average day, which for most businesses offsets the bulk of weekday consumption.

Systems of this size are designed around your interval data, your roof structure and your network connection, so the package here is a starting point rather than a fixed kit. Our commercial solar team models the numbers on your actual half hourly usage before we quote.

At 227 panels this is the largest package we list, sized for a warehouse, a club or a school with the roof and the daytime demand to use it.

Canadian Solar’s 440 W panels are the black frame N-type modules we fit across the Mid North Coast. Read our Canadian Solar panel review for how they compare. The Goodwe inverter is covered in our Goodwe inverter review.

On the Mid North Coast a well sited system averages about 4 kWh per kilowatt per day across the year. For this package that is roughly 390 to 420 kWh a day, or around 147,800 kWh a year, with more in summer and less in winter. A north facing roof does best, but east and west facing arrays still perform well here and can spread production across the morning and afternoon.

Allow about 454 square metres of clear roof for the 227 panels, plus clearance from roof edges, vents and anything that throws shade. Roof pitch, orientation and any shading are all checked at the free site assessment, and we design the layout to suit your roof rather than a standard drawing.

The federal solar rebate for systems under 100 kW is applied as a point of sale discount, and larger systems earn large scale certificates over time. We advise on which applies to your installation. Finance is available through Brighte with $0 interest options and repayment terms from 6 to 84 months, so a system can be paid off from the savings it makes. Details are on our payment options and finance page.
