Fields of application

Prisma ® PVT - The ecological solution for numerous applications

The combination of heat and power generation with just one collector makes the PRISMA PVT hybrid modules an absolute multi-talent. On limited roof surfaces, you reap maximum energy yields. This results in numerous application possibilities; starting with single and multi-family homes, to schools, university buildings, hospitals and retirement homes, to swimming pools, hotels, campsites and sports facilities. PVT modules can also be used very well as a regenerative energy source in horticultural businesses or agriculture.

Prisma® for single-family houses

PRISMA® PVT makes sense both with conventional boilers and in combination with heat pumps to significantly reduce your consumption of fossil fuels, biomass and grid electricity. Depending on the system concept, there are additional BAFA subsidies of up to 35 percent on the entire components, including installation. If necessary, the solar power can supply the heat pump with electricity; in combination with a solar battery, a high level of own power consumption can be realized. The noise level of air-source heat pumps, which is also annoying for neighbors, is eliminated. The electric filling station at the house additionally ensures a favorable supply of your electric vehicle with regeneratively generated energy. In perspective, this investment makes sense with foreseeable rising prices for fossil fuels and high electricity costs of the suppliers. A sustainable supply of your house with a high share of renewable energy is guaranteed for decades. A permanent CO2 reduction through this innovative energy supply concept contributes to the preservation of our living space for you and your children.

PRISMA® as swimming pool heater

The thermal power of a sufficiently sized PVT system can be used to heat the swimming pool. This is also possible outdoors, extending the swimming season at pleasant temperatures both in spring and late summer. A suitable plate heat exchanger is used to transfer the heat energy. As a rule of thumb, 70-80 percent of the area of the swimming pool should be calculated here as the PVT area to be installed.

PRISMA® for hotels and restaurants

The demand for heat and electricity in hotels and restaurants is enormous. Guests want to shower or bathe every day, swimming pools and wellness oases require large amounts of hot water or need to be tempered. Kitchens also have a large hot water demand for dishwashing and general hygiene precautions. Here, TWL's PVT rooftop power plant can provide a significant boost of renewable energy.

PRISMA® for neighborhood solutions

The TGA planning of quarters under consideration of environmental aspects is a complex task for every planner. Increasingly, cold local heating networks are being implemented or probe bore fields are being created to meet the heating requirements of large areas. Here, PVT modules can be ideally used to regenerate the probe fields or to increase the temperature of the heating networks. The roof areas can thus be optimally utilized from the outset with regard to solar energy generation. The heat pumps used can additionally be supplied with electricity, especially if battery storage is used. Seasonal storage systems, such as ground storage tanks with 10,000 m³ plus or large-scale ice storage tanks, can also be used to make the energy stored by the PVT collectors in the warm season usable for heat pumps on the source side.

PRISMA® for public buildings

Ecological aspects are playing an increasingly important role in municipal planning. Political decision-makers are increasingly obliged to present citizens with forward-looking, sustainable concepts in public spaces. Schools and university buildings, kindergartens and sports facilities offer a wide range of opportunities here to replace the high demand for electricity and heat in a climate-neutral way, in part via PVT collectors.

PRISMA® for campsites

Campsites are in peak season from spring to late summer. For the operators, this means extremely high costs for the provision of hot water for showers, washing machines and dishwashers. There is also a high demand for electricity. Here, PVT hybrid modules from TWL are the ideal solution for long-term cost reduction. They deliver maximum energy yields with low space requirements - year after year.

PRISMA® for sports and wellness centers

After sports, it's off to the showers. The hot water consumption of sports centers is high all year round. Here, PVT modules from TWL can contribute a good part to the annual base load. In addition, photovoltaics provide electricity for lighting or for operating hair dryers.

PRISMA® for nurseries

Commercial greenhouses in horticultural businesses have a high demand for electrical and thermal energy. Early cultivation of useful and ornamental plants and the desire for the earliest possible harvest dates make it essential to install powerful central heating systems.
The greatest heat demand is in the colder seasons, when the solar energy source is naturally less productive. In summer, the high solar yield of the PVT system is then of little use. If one wants to use PVT collectors sensibly and thus increase the renewable energy share of the total energy demand, there is no getting around seasonal heat storage. Large geothermal heat storage tanks, ice storage tanks or concrete cisterns can be charged by the PVT collectors in summer. These heat quantities are then available in the cold season and can then be raised to the required temperature level via large heat pumps.

PRISMA® for hospitals and nursing homes

The energy demand for electricity and heat in hospitals is at a high level all year round. Nursing and hygiene have a consistently high demand for hot water. Integrated laundries also consume large amounts of hot water. The electricity demand of a hospital is immense. The roof surfaces of a hospital allow for large-scale PVT systems. This allows significant amounts of the total energy demand to be generated regeneratively.

PRISMA® for the regeneration of earth probes

Geothermal probes draw their heat from the surrounding soil. The heat input from above or from groundwater layers is often too low. As a result, the surrounding ground increasingly cools down. The source temperature of the heat pump thus decreases and increasingly worsens its annual performance factor. The increasing density of geothermal boreholes in residential areas further worsens the yield situation. In order to ensure a permanent profitable operation of 50 years and more, the borehole heat exchangers can be regenerated in summer by charging them with heated water from the PVT system. The surrounding soil is heated and this thermal energy is then available in winter. The efficiency of the primary energy source is thus permanently maintained.

PRISMA® for paint shops

High temperatures prevail all year round in spray booths and paint drying areas. Covering a significant proportion of this high energy demand from renewable sources should be the goal of every plant planner in this segment. TWL PRISMA® PVT collectors can make a significant contribution here.

PRISMA® for car washes

Vehicle wash facilities have an enormous, year-round demand for hot water and electrical energy. Rising energy prices and increasing environmental awareness among customers have been forcing operators to install regenerative energy sources for years. Up to now, PV systems or solar thermal systems have mostly been installed. With PRISMA PVT 3.0, a collector is now available for the carwash service sector that both makes a significant contribution to solar preheating of the wash water and takes into account the high power requirements of the systems. Compared to a pure PV system, the energy yield of a PRISMA® PVT system is more than three times higher, and this on an identical roof area!

PRISMA® - Ground-mounted systems for anergy grids

Anergy networks or cold local heating networks are increasingly being designed and implemented to supply municipalities or settlements. In the warmer seasons, the excess thermal energy from the PVT collectors can be used to regenerate the near-surface geothermal systems. Another storage option is large earth basin heat storage tanks. During the cold seasons, energy is extracted from these sources to supply heat pumps, making it usable. Due to the relatively low temperature level of the stored energy, up to a maximum of 25° C, the supply lines and, if necessary, the earth basin heat reservoirs need to be insulated only slightly or not at all, which has a positive effect on the construction costs for these energy networks.
In contrast to an energy network fed purely by solar thermal energy, the additional electrical energy available means that the electricity generated is available for operating the heat pumps or other electrical consumers.
