    Exciting new TRaCE project! Overheating remains a key limitation of solar PV systems — reducing efficiency and shortening the lifespan of solar panels. But what if that excess heat could be captured and repurposed? Coolsheet, co-founded by Tom Hoole and led by Doug Smith, is an innovative Photovoltaic Thermal (PVT) that boosts energy output, extends panel life, and delivers renewable heat — all from the same system. Now in partnership with UNSW through a Trailblazer for Recycling and Clean Energy (TRaCE) project, Coolsheet is advancing to the next stage of development. Led by Professor Robert Taylor, the project is focused on scaling up manufacturing through advanced R&D and testing real-world applications across residential rooftops, industrial facilities, and public infrastructure such as swimming pools. Benefits: 🔹 Delivers up to 15% more energy over the lifetime of the solar system 🔹 Enhances solar panel lifespan 🔹 Generates both electricity and usable heat from the same system Coolsheet™ represents a significant step forward in integrated clean energy technologies, helping unlock more value from solar infrastructure while accelerating the transition to net zero.

  • Fantastic Clean Techology Innovation Showcase event run by NSW Department of Climate Change, Energy, the Environment and Water today to round out Climate Action Week Sydney. Unusually useful knowledge sharing session for fellow entrepreneurs thanks to the engaging and insightful hosting from Hebbat Manhy of Cicada Innovations. Well done also Hebbat for one of the most elegant calls to action I’ve heard in a long time - we need more of this politely delivered “action shaming” 😁 than ever now. I didn’t realise that NSW has tipped in a bit to help Greenhouse, Climate Salad, EnergyLab, The Melt and SparkLabs Cultiv8. Well done NSW, all these teams are providing invaluable resources, help and acceleration for the startup ecosystem - Coolsheet is feeling well supported on our scale-up journey.

    Traditionally, heating water for aquatic centres is expensive and inefficient. Newer systems with a heat pump and solar PV systems installed are an improvement, but there are further efficiency and cost savings to be made by installing a PV thermal system, such as the Coolsheet system which is to be installed at an aquatic centre. By recovering waste heat from the solar PV system and transferring it to the heat pump for water heating, this increases electricity production from the solar PV system and reduces the electricity required for heating in the heat pump system – win-win! The aquatic centre installation will have 4 solar arrays in parallel, which will allow for testing to determine the optimum operating procedure for this site to minimise costs and greenhouse emissions and allow for further optimisation of the system design for future projects. The research component will be undertaken by UNSW and the project is supported by Coolsheet and Energywise Australia with in-kind support from EnergyAE, and Direct Energy Australia.

    The Coolsheet team had a fun day yesterday at UNSW in Sydney, presenting a guest lecture to the Solar Thermal course students in the School of Mechanical and Manufacturing Engineering. Always invigorating and inspiring to be on campus. Thanks Prof Robert Taylor for hosting us...and for the help in moving a Coolsheet from the rooftop test lab over to the lecture theatre! (note it does not require 6 people to carry a Coolsheet but many hands...😊) Great day out for our Coolsheet Interns over from the US for the northern summer - many thanks Gracie White, Dakota Patuwo, Thea Burhan and Connor Lause for your inputs and efforts over the past couple of months. Hugely appreciated.

  • Thanks A2EP team. As a result of this webinar, we've had enquiry from Africa, Ecuador, El Salvador, Ireland, NZ and the US! For continued traction closer to home, we're currently focusing on helping Commercial PV installers and Energy Efficiency consultants in VIC and NSW as Coolsheet qualifies for VEECs and ESCIs (or ACCUs), which can bring the payback period in comfortably under 5 years for our renewable heat solution.

    WATCH: Recently as part of our Heat Pump Month, Coolsheet CEO Doug Smith outlined how Coolsheet's innovative, easy-to-install solar thermal technology can integrate with heat pump systems by harnessing the waste heat from solar PV panels to pre-heat water (and simultaneously optimise the solar PV performance by cooling the PV panel!). Doug described this as a classic "twofer" - getting two benefits out of the one technology. And it improves energy productivity by getting more out of the solar PV panels and reducing the amount of energy needed for water heating by heat pumps. View Doug's presentation here: https://lnkd.in/g8Gr6ACa This presentation was part of a webinar presented by the Australian Alliance for Energy Productivity on 13 March 2024: Modelling, optimising & integrating - getting more from your heat pump, which can be viewed here: https://lnkd.in/dVaNGukg #energyproductivity #solarthermal #solarPV #wasteheat #heatpump #heatpumps Tom Hoole
