Adapt Solar Thermal Technology To Precisely Meet Your Needs

Our applications are adaptable to your specific usage needs. Whether your hospital system wanting to decrease costs for heat production or a homeowner search for relief on your utility bill, we can adjust the application to meet your goals. 

Virtu HOT is the next generation in solar thermal technology. It’s a solar thermal collector that heats water from the power of the sun.

Solar thermal can decarbonize global heat demand across a number of sectors, from manufacturing to hotels and leisure complexes. By using Virtu HOT customers can reduce their dependency on fossil fuels and future-proof hot water supply.

Virtu PVT redefines solar energy. It’s a hybrid solar collector that combines solar photovoltaics (PV) and solar thermal technology, to generate both electricity and heat from a single solar collector.

Unlike solar PV, which generates only electricity, Virtu PVT performs at optimal efficiency by also capturing the sun’s heat energy up to 80°C.

Virtu is a complementary technology

Virtu is a complementary technology. Like all solar thermal technologies, it can be easily combined with existing heating technology, such as heat pumps. This integration is most efficient when Virtu pre-heats the system, which is then topped-up and maintained by the backup heat source. It contributes to the decarbonisation of heat and utilises existing high-efficiency heat generation assets. As a roadmap technology, Virtu enables the energy transition to low-carbon heat through distributed, renewable, zero-carbon energy generation.

To meet net zero targets, manufacturers must dramatically reduce their emissions. This is a significant challenge due to their high-energy intensity, and increasing carbon taxes, adding pressure to decarbonise. For a typical manufacturing site, energy demand far exceeds the generation capacity of the available area for renewables. Naked Energy’s Virtu products generate more energy with less space. Virtu provides pre-heat and process heat up to 90°C while reducing hard-to-tackle scope 1 emissions, unlike standard solar PV technology. We work with manufacturers of food & beverage, pulp & paper, textiles, pharmaceuticals, fast-moving consumer goods and other manufacturers.
Hotels & Leisure Centres
For hotels with high thermal demand all year around, Virtu’s high-energy density is ideal, especially for urban environments with limited roof area. Resort-style hotels are often in locations with lots of solar irradiance, but traditional energy sources are expensive, space is limited and supply is insecure. For these hotels, Virtu can eliminate these challenges while tackling the scope 1 emissions of domestic hot water (DHW), laundry and pool heating.
Public Sector
Governments around the world have committed to net zero. To achieve this, decarbonising heat in public sector assets is a priority. In many countries, governments offer strong subsidy support to finance projects which reduce the carbon emissions of their assets. Our Virtu products are Solar Keymark certified, making them eligible for such funding. Virtu can help decarbonise a range of public sector assets with large thermal demand. We work with social housing, schools, swimming pools, fire stations, hospitals, university accommodation blocks, prisons and heat networks.
Multi-family Residential Developments
Many new residential developments are moving away from gas for heating. Providing affordable warmth to residents remains a priority. Installing Virtu during retrofit or in new developments can halve residents’ energy bills while future-proofing building standards for low-carbon homes. Virtu works in parallel with thermal storage to reduce costly electricity network upgrades and adds to the aesthetic value of the property. We work with social housing, residential developers, heat networks and care homes.

There are two product models: VirtuPVT and VirtuHOT. Both products are modular and designed to be flexible and meet various levels of demand. Each model can be supplied with reflectors or without. VirtuPVT has a standard absorber angle of 35°and VirtuHOT can be manufactured with different absorber angle specifications at either -20°, 0°, +20°, +35° with the angle being dependent on the installation requirements.

Our products are designed for maximum efficiency. In both high density (HD) and non-high density models, the PVT tubes are the same. Non-HD models include reflectors between the tubes, whereas HD projects don’t. Project location informs whether HD or non-HD models will be installed. HD models are typically installed on sloped roofs in locations close to the equator.

VirtuPVT delivers up to 4x more energy than solar PV, and more carbon savings for many public, industrial and commercial buildings that require hot water or other forms of heat. It also delivers lower running costs and better return on investment than standard PV systems.

VirtuPVT has a market-leading peak efficiency of up to 80%, at 20% PV and 60% thermal. VirtuPVT displaces more fossil fuels than other distributed renewable energy systems, and generates greater carbon savings. VirtuPVT generates both clean electricity and heat, which dramatically reduces both Scope 1 and Scope 2 emissions, and contributes to net zero goals.

A single hybrid collector reduces installation time as well as costs. It delivers more carbon savings than separate solar PV and solar thermal products, and the result is overall greater return on investment. Additionally, Virtu’s beautiful aesthetics distinguish them from other collectors in the marketplace.

Yes. Virtu is a complementary rather than a competitor product to heat pumps. Virtu can be combined with ground and air-source heat pumps to support their overall performance and provide an alternative source of heat when the sun isn’t shining. However, the carbon emissions and operating costs of a heat pump will vary depending on the local grid when operated without solar power.

Yes, solar thermal still works in the winter. But like all solar products, Virtu generates more energy during the summer months. However, seasonal thermal storage enables end-users to benefit from solar thermal throughout the year. Thermal energy is collected and stored in warmer months and can be used in the opposing season when it is needed most. A prime example of a large-scale thermal storage project is Drake Landing Solar Community in Canada:

Water and propylene glycol mixture are used to avoid freezing in winter. The correct glycol concentration is determined by the location of the project. In locations where freezing temperatures don’t occur, it is possible to use de-ionised water without glycol.

Our product does not require any more maintenance than conventional solar thermal or solar PV arrays and generally requires very little maintenance to function. We work with trusted partners to install Virtu products, following strict installation methodologies to achieve the best possible results. The performance of our Virtu products is monitored digitally and in real-time with our Clarity247 platform. Well-maintained systems can expect a productive lifetime of at least 20-years.

We ensure that our products meet robust certification and the highest industry standards. The standards included in our Solar Keymark certification are: ISO 9001, EN 61730, EN 61215-1, ISO 9806, EN 12975. They cover our supply chain, the manufacturing of our products.

Yes. We ensure that our products meet robust certification and quality assurance standards. Our standard warranty is five years. However, customers who use an approved installer and take O&M will receive the maximum industry warranty of 10 years.
