Commercial Grid Connect Solar Systems

Commercial Grid connect solar systems will produce up to 200kWh per day on average, or 300kWh in summer. Enough to power air-cons, pumps, coolers, motors, servers or entire office buildings.

The main difference between a commercial grid connect solar system and an ordinary rooftop solar system is its size. The physical size of the inverters is slightly larger, but these inverters connect to a lot more solar panels. Our largest system example incorporates 144 panels. Only very large sheds or industrial buildings will have enough surface area to mount that many panels. Ground mounted framing systems can also be used if roof space is not available.

Note: All commercial installations will require a site inspection.

19.8kW 3-Phase Solar System

little man watering money

This grid connect system features 60 Trina solar panels with a total of 19800 watts. On average, the panels will generate 70 kWh/day. If you manage to self-consume all of that power, you will save $8900 each year (@ 35¢/kWh).

You will require at least 110 square metres of roof space. Download our roof installation questionnaire.

Fast Return on Investment

We all use energy around the clock, but businesses typically use the vast majority during daytime hours. The prime candidates for a commercial solar power system are office buildings, manufacturing workshops, schools, or any other building where air-conditioners run during the day. Such businesses can cover +80% of their energy needs with a home-grown electricity.

Commercial Energy usage and production

The above data was taken from commercial premises that operate from 7am to 7pm. The grid-interactive solar power system, combined with a Tesla Powerwall2 battery, supplies most of the business' need.

The bigger the self consumption, the faster the system will pay for itself. A well designed commercial solar system may have a return on investment of as low as 2 years.

Other Incentives

Commercial solar systems up to 100kW (with approved panels and inverter) still generate STCs, e.g. the 144 panel solar system would currently create $24548 worth of STCs.

Furthermore, businesses with a turnover from $10 million to less than $50 million are currently eligible for the instant asset tax write-off. This applies to assets that cost less than $30,000. But hurry, the scheme closes soon - a solar system would have to be installed and operational before 30th June 2020. Source.

System Examples

The three system configurations are examples only. There are many other possible configurations, e.g. tilt frames (for flat roofs) or ground mount frames or even frames that serve as car ports.
Note: RPC will have to conduct a site inspection before a proper quote can be made.


We install solar systems in Northern NSW and Southern QLD.


QLD:
Gold Coast (from Coolangatta to Southport), Nerang and Hinterland (Beaudesert) and out West (Warwick, Stanthorpe, Killarney)


NSW:
Northern NSW (Tweed Heads to Yamba, including Evans Head, Byron Bay and Ballina); the Far North Coast Hinterland (Grafton via Lismore to Murwillumbah) and out West (Casino to Tenterfield, including Drake and Tabulam, as well as Woodenbong and Bonalbo)

For larger system we also go up to Brisbane or down to Coffs Harbour and even Glen Innes. Other places by arrangement.

We are Open for Business

Rainbow Power Company would like to assure our customers that we are trading (not quite as normal). System designers are working from home and can customise a quote for you (free of charge) over the phone and online. We are still dispatching and posting items, with safety precautions in place. You can still order online or over the phone, and pick up items from RPC (our show room is closed however, and appointments must be made to pick up orders). We are still doing site inspections, keeping the recommended social distancing.
