100kW photo voltaic programs are among the many hottest business photo voltaic system sizes in Australia, as this measurement is the cutoff level for up-front incentives by way of the federal authorities. This text offers an outline of a lot of the key factors that companies have to know if they’re contemplating a 100kW photo voltaic system for his or her business premises. The picture above is a 100kW photo voltaic array for the Nationwide Golf Membership in Mornington Peninsula, Victoria. (Learn extra about this mission)
100kW Photo voltaic System Prices
The price of putting in a photo voltaic system has fallen considerably lately due to a lot of components, together with Australian authorities incentives for renewable vitality, rising competitors between photo voltaic panel installers and element producers, and international manufacturing tendencies. Coupled with rising business electrical energy costs, photo voltaic programs within the 100kW vary provide a compelling money-saving and funding choice for a big selection of enterprise varieties. Accordingly, uptake of business solar energy has elevated considerably in Australia within the final a number of years – with 2020 wanting set to be the nation’s greatest yr but.
As per the beneath desk, the common value of a 100kW solar energy system is $89,000 together with GST and the STC upfront rebate.
The graph beneath – from our Business Photo voltaic PV Worth Index – reveals common worth tendencies for 100kW photo voltaic programs since Photo voltaic Alternative began holding monitor in Might 2014. (The Index additionally incorporates pricing for 10kW, 30kW, 50kW and 70kW programs).

Power yields for 100kW photo voltaic programs
There are a lot of components that affect the output of photo voltaic PV programs. These embrace the orientation and tilt angle of the photo voltaic panels, the presence or absence of shading, common system working temperature, and the standard of the system’s elements. All of those components are considered when a system is designed as a way to arrive at an inexpensive estimate as to what that system’s energy output will probably be as soon as it’s operational.
The theoretical higher restrict for the quantity of energy a flat-panel 100kW photo voltaic system (or any flat-panel system) can produce is set first by the quantity of incident daylight on the world the place it’s positioned all through the course of a day, month, season, or yr. It goes with out saying that totally different areas of the nation obtain totally different quantities of photo voltaic irradiation. As a really tough information, a system in Australia will produce 4 kilowatt-hours (kWh) per kW of put in capability per day, averaged all year long. This determine will in fact be larger in sunnier areas and decrease in much less sunny spots (Brisbane sees extra daylight than Hobart, for instance) and the season (energy technology is larger in the summertime due to the longer days). Photo voltaic Alternative can calculate this precisely on your mission utilizing native BoM data and an evaluation of the roof house you’ve got out there utilizing Nearmaps software program.
| 100kW Photo voltaic Panel System Output by Capital Metropolis | |
| Adelaide | 385 kWh per day |
| Brisbane | 400 kWh per day |
| Canberra | 385 kWh per day |
| Darwin | 440 kWh per day |
| Hobart | 310 kWh per day |
| Melbourne | 335 kWh per day |
| Perth | 420 kWh per day |
| Sydney | 360 kWh per day |
Solar energy programs generate extra energy in summer season than in winter
An ordinary 100kw photo voltaic system in Sydney, NSW would produce about (3kWh x 100kW =) 300kwh on a winter’s day, whereas within the peak of summer season the identical 100kw photo voltaic PV system would produce round (5kWh x 100kW =) 500kWh. An identical system in Brisbane may produce as a lot as 350kWh in winter and 550kWh on a day in summer season.

Monetary returns for 100kW photo voltaic programs
Based on our personal knowledge (from practically 300 enterprise circumstances compiled in 2021), payback durations for appropriately sized commercial-scale photo voltaic programs in Australia are round 3 years on common, with inner charges of return (IRR) simply hitting 20-30% in each state & territory within the nation. After factoring in the advantages of the moment asset write program the federal government launched in response to COVID-19 the payback interval is at present even higher.
That being mentioned, the funding case for putting in a 100kW photo voltaic system is dependent upon the circumstances. The first components that affect photo voltaic system ROI are:
- The up-front and ongoing prices related to the system
- The price of mains electrical energy
- Strategies of cost/financing for the system
- The feed-in-tariff, if any, for surplus energy fed into the grid or bought to a 3rd social gathering.
These are mentioned beneath:
1) Whole value of the system
The 100kW photo voltaic system prices we now have outlined above (for instance $80,840 inc. GST in Sydney as of mid 2020) are common costs for installs with out vital extras for issues. By way of our tender administration service we now have installers prices for required extras corresponding to switchboard upgrades, crane rent, ground-mounted programs, tilt frames or micro-inverter programs. With a purpose to get one of the best worth and worth on your system we’d at all times advocate to supply a lot of quotes from certified installers.
2) Electrical energy costs
Every enterprise is usually in a distinct place with reference to their buy energy with retailers and skill to entry good charges. Components influencing the electrical energy prices embrace the variety of websites the businsess owns and might discount with to acquire a contract, the geographical location and distribution community supplier, peak demand and time of vitality use. Usually talking the upper your electrical energy charges means the upper the ROI for a photo voltaic mission.
3) System financing
Photo voltaic might be funded upfront with a payback interval of 2-5 years, nonetheless many companies have progressed on a money stream constructive foundation below a financing settlement. That implies that the repayments on the mortgage are lower than the financial savings that the photo voltaic system delivers. The enterprise case make a average saving by way of the lifetime of the mortgage and have step lower in operational prices are the tip of a 5 – 10 yr finance settlement. Charges for photo voltaic financing are sometimes low between 4 – 6 % relying on mission measurement and credit standing.

4) Photo voltaic feed-in tariffs
Usually talking, commercial-scale photo voltaic programs are designed and put in to offset energy payments as most business energy utilization is throughout daylight. That mentioned a feed-in-tariff might add the icing to the cake and ship some profit to solar energy fed again to the grid – e.g. on weekends. Photo voltaic Alternative’s method is usually to exhibit by way of a enterprise case that the photo voltaic mission will probably be viable and not using a feed-in-tariff as there may be in most states there is no such thing as a obligatory minimal and it’s not assured {that a} 100kW system will probably be permitted by the native community to export photo voltaic vitality.
