1 SOLHOTAIR TECHNOLOGY High efficiency solar technology for use in solar heating panels

2 Solar technologies SOLHOTAIR technology among other solar technologies Conversion of solar energy into heat Solar thermics Conversion of solar energy into electricity Photovoltaics SOLHOTAIR air collectors Water collectors

3 SOLHOTAIR solar air heating panel functions 1. Efficient heating of service rooms using air heated with solar energy in winter and during transition periods (useful heat) 2. Supply of heat needed for industrial processes (process heat)

4 SOLHOTAIR solar heating panel - applicability residential buildings public buildings (sports halls, shopping malls, etc.) restaurants, hotels storage halls and shop floors agricultural facilities such as drying rooms, greenhouses, poultry farms, etc. sacral buildings and museums as a source of heat for absorption cooling equipment as a source of heat for improved heat recovery efficiency

5 SOLHOTAIR operating principle The incoming air (drawn in mechanically) is directed into the air ducts. The upper surface of the air ducts is coated with a layer that selectively absorbs solar radiation. The air temperature increases all the way through the air ducts. On sunny days the temperature of the outgoing air is higher than that of the incoming air by up to 40 C.

6 Innovation of SOLHOTAIR technology A. Turbulent instead of laminar air flow due to the use of a vortex generator B. Operation in either an open or closed loop C. Use of innovative insulation material D. Thermal barrier from modern aluminosilicate materials E. Concept of floating solar glass F. Smart module to control the heating process G. Structural optimisations to increase the durability of the equipment

7 Result of the innovations applied The efficiency of air solar collectors built using SOLHOTAIR technology grows up to 83%, which represents over 20 percentage points more than the best solutions currently available on the market. The use of SOLHOTAIR technology enables to obtain high efficiency rates even if sunshine is feeble. Thus, compared to other solar technologies, rooms can be heated more efficiently. Heat can be generated even on a cloudy day, as it is the internal air which is heated in SOLHOTAIR technology. With more sunshine, fresh external air is heated. The efficiency rates of systems using SOLHOTAIR technology are even five times as high as customary photovoltaic panels.

8 Efficiency Comparison of the SOLHOTAIR collector and photovoltaic panels

9 One 1.5m² large panel can generate up to 2000kWh of useful heat per year, which substitutes : Effects on the environment and energy savings 200m³ of gas 328kg of coal LOW PARTICLE EMISSIONS REDUCED BY MORE THAN 650kg of CO² per year

10 Potential of SOLHOTAIR technology on the Polish energy market Renewable energy sources are a real alternative to firing worst quality fuels in boilers and to improve the life quality of inhabitants. Heat and cold account for 58% of consumed final energy in Poland (electricity represent only 20%) and offers the greatest potential for saving energy, reducing carbon dioxide and developing renewable energy sources. In residential buildings heating and hot water costs exceed 80% of total energy consumption expenses. Data source: Institute for Renewable Energy

11 Share of air solar panels in the European and the global solar collector markets According to the 2016 Edition of the Solar Heat Worldwide report, air solar panels account for 0.4% of the global solar collector market and 1.2% of the European market.

12 Influence of SOLHOTAIR technology on the growth of the niche market High, 83 per cent heating efficiency of SOLHOTAIR technology and wide applicability of the solution are two factors that overcome the barrier of this market. SOLHOTAIR technology shows a great commercial potential and the employment of the solution should ensure a competitive edge.

13 A variety of benefits for the manufacturer Large customer market general applicability Availability of innovation and environment support packages (National Intelligent Specialisations 7, section IV, item 2) Product easy to manufacture compared to other renewable energy sources Favourable relation of the energy used to manufacture the product to the energy returned by the equipment Favourable relation of the manufacturing costs to the sales price

14 A variety of benefits for the user Considerable savings on heating costs Improved comfort in the rooms always fresh and warm air Availability of EU support programmes Fastest return on savings as compared to other renewable energy sources

15 Research, certification The technology has been tested at the Department of Heat Engineering, Heating Technology and Ventilation directed by Professor Miroslaw Zukowski, Bialystok University of Technology Faculty of Civil and Environmental Engineering. The technology has been tested at the Fraunhofer-Insititut für Solare Energiesysteme ISE in Freiburg/Germany to obtain a European certificate needed to get listed for renewable energy source subsidies. According to the Fraunhofer Institut, SOLHOTAIR technology is currently the best solar thermics technology in Europe.
