A 30 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 70 panels across about 140 square metres of roof it produces around 117 to 126 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.

Seventy panels is a typical size for a workshop, a childcare centre or a medical practice with a solid weekday load.

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 117 to 126 kWh a day, or around 44,300 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 140 square metres of clear roof for the 70 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, paid as small scale technology certificates, is applied as a point of sale discount on every system we install, so the quote you receive already has it taken off. 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.
