Australia’s wineries go green using solar energy

Australia’s wineries go green using solar energy

More Australian wineries are turning to the sun, making the switch to solar power to help in wine production. Driven by rising costs of electricity from non-renewable sources, lower costs of solar power installation, and the potential benefits of producing own power, many wineries haven taken the bold step of investing in more renewable sources. By utilising solar energy for growing grapes and producing wines, wineries in Australia can both save on major costs and reduce their overall carbon footprint.

Electricity is the biggest expense in wine production

For most wineries in Australia, electricity is their largest expense item in the production of their wines. The Australian Energy Market Operator (AEMO) estimates that around 40% of expenditures of wineries go towards electricity, whilst the South Australian Wine Industry Association (SAWIA) says that refrigeration eats up 50-70% of total power costs. Thus, it is no surprise that vineyards look for ways to reduce energy expenses.

Investing in renewable sources makes sense that will drive electricity expenditures down, lower overhead costs, and improve margins. For producers of quality Australian red wines, solar power not only reduces energy costs, but also maximises commercial roof space and reaffirms their commitment to a lower carbon footprint.

Incentive to attract investments in solar power

Solar power adoption surged in Australia in 2008, and even though costs of materials and installation were high, government incentives were also widely available until 2011. Between 2011-14, the prices of solar systems fell. From 2014 to present, there is relative stability in the solar system industry. Photovoltaic (PV) system prices are down significantly and there are existing incentive schemes for solar panels and batteries that are offered at state level, making investments in the area still attractive.

For 2020, interest-free loans up to $9,000 for a solar battery and $14,000 for a solar PV and battery storage system for households with an annual income of $180,000 or less are available. Under the Small-Scale Renewable Energy Scheme, both households and smalls business in Australia that install small-scale renewable energy systems may be eligible for assistance to help with the purchase cost. Eligible participants may be entitled to small-scale technology certificates which can be sold to recoup a part of the purchase and installation cost.

Wineries adopt renewable power sources

An independent report produced by AgEconPlus revealed a 13% increase in the economic contribution of the wine industry since 2015 or an increase of roughly 3% per year. Strong wine exports are largely responsible for recovery in the wine sector. But, the competition is tough and the over 2,000 wineries in Australia have to stay competitive.

In fact, wineries were some of the earliest adopters of solar energy, with dozens in South Australia harnessing solar energy for wine production. Some wineries that have in excess of 100kW solar systems include D’Arenberg, Wirra Wirra, Sidewood, and Peter Lehmann. Recently, Pernod Ricard has become the first large wine company in the country to achieve 100% renewable electricity with the completion of Australia’s biggest combined winery solar installation. According to the winery’s chief operations officer, Brett McKinnon, “being sustainable and responsible is an important part of their business and they want to reduce their impact on the communities where they operate”.

Australian wineries recognise the opportunities to tap into solar energy and enjoy the cost-saving and environmental benefits. Using renewable sources not only lowers electricity costs, but also fulfils a company’s global-minded goals.

Container Roll Out Solar System – Portable Solar

ARENA (the Australian Renewable Energy Agency) have awarded a grant to ECLIPS Engineering to design, manufacture, and test its ‘diesel killer’ portable solar offering, the Container Roll Out Solar System (CROSS).

ECLIPS Engineering (formerly Sea Box International) are a Canberra based engineering firm hoping to do their part to help Australia do away with diesel generators in situations where a temporary power supply is required. They have created factory assembled 20 and 40 foot long solar panel arrays which fit in shipping containers and have minimal setup / teardown time. 

According to RenewEconomy, each 20ft unit has 2.1kW of power, and 7 of them can fit in a shipping container. The 40ft units has up to 4.3kW and can also fit seven to a container. 

ARENA have given CROSS $703,468 to to help the project, which has aims more lofty than just replacing diesel generators at work sites – the Container Roll Out Solar System could also help in defence situations, disaster recovery, for humanitarian needs, or for ‘temporary network augmentation’ (i.e. helping the grid if it’s malfunctioning or under severe stress).

ARENA CEO Ivor Frischknecht spoke about funding the project, and how they hope to see an eventual replacement of diesel generators in 99% of cases:

“CROSS units can be deployed in off-grid and fringe-of-grid areas, displace or offset diesel consumption and improve the security of existing networks,” he said.

“These renewable options can reduce some of the barriers to entry for potential renewable power users in remote locations, including short project durations and where power systems need to be periodically relocated,” Frischknecht said.

“Renewable energy can provide an emissions-free, silent energy system that could replace diesel generators in the long run.”

We’ve already reported on the Maverick by 5B, which is another prefab, low-cost ground mounted solar array – it’s great to see some more options available to try and minimise the amount of diesel generators used as a temporary power supply. 

We’ll keep you posted how the project goes and what the next steps are!

Maverick by 5B – a prefab, low-cost solar array.

Australian company 5B have launched the Maverick (MAV) portable solar farm – their easily-transported large-scale portable solar farm with a continuous array design. Because of this, a solar farm built with MAV can generate between 180 – 200% more MWh per hectare than fixed tilt or single axis tracking designs. This could be a game changer for farmers, remote communities, film crew, or anyone who needs to use a large amount of power and don’t have grid access. Launched in July this year, the ‘solar farm in a box’ has been gaining traction for anyone looking for portable solar in Australia.

The Maverick is a continuous array, which means DC cables don’t need to be trenched, saving setup time and reducing the potential for any errors when setting up. According to the 5B website, two people are able to roll out a 12kW MAV in ten minutes with ‘standard site vehicles’. Here are some further stats on the MAV:

  • Ground mounted DC solar array of 32 or 40 PV modules.
  • Any 60/72 cell standard framed PV module can be used if you want to choose (they come with Jinko panels by default).
  • Each MAV weighs approximately three tonnes. 
  • MAV is 5m wide and 16m/20m long (32/40 modules) once deployed.
  • Modulates oriented in a concertina shape at 10-degree tilt (electronically configured and ready for integration at site).
  • Simple deployment via a forklift and 2-3 people. As per the 5B tagline – “100 kilowatts fully installed before lunch, and 1 megawatt in a week” – pretty impressive!

They’re modular as well; you can ship four 32-module MAVs in a standard ISO 20 foot container (similar to the Renovagen solar carpet we discussed yesterday)
