OSCAR Photovoltaic Thermal: Electricity generation + Solar heater (air and water). Combined solutions for all your energy needs. Efficient use of solar energy resources

🔋Solar photovoltaic panels generate electricity

🔥Heating air and water

On a sunny day, the temperature of the injected air is approximately 25ºC higher than the ambient temperature. In addition, the air temperature on the sunny side usually rises more than 10ºC under the big sun. Single-chip PVT (Irradiance 1000W/㎡, area 2.23㎡) can usually add 500-1300W heat to a room.  The power consumption of the fan is low, and the Coefficient Of Performance is more than 30 times. Roof installations receive over 20% more solar radiation than wall. Providing air 25ºC higher than the ambient temperature under high air volume can more than double the energy efficiency of the air source heat pump and produce hot water or ultra-high temperature air. In a windy environment, the heat from the front of PVT (hot water) will be blown away by the wind, and PVT (air) can absorb more solar heat, higher efficiency.

🌬️Ventilate the building for a healthy climate

The fresh air of solar panel squeezes the turbid air out of the room, reduce carbon dioxide; discharge unpleasant odors which might cause allergies and discomfort, keeping the air fresh and oxygen-rich. Each solar panel can provide 100m³/h dry, warm air is blown into the room. In the case of cloudy days without sunlight, the room can also be properly ventilated. Ventilation is a key factor to the state of every building. Stagnant indoor air increases the risk of fungi, rot and other unwanted consequences. When dry and warm air keeps flowing in the room, the damp, rot or mold would be long-term reduced. The WHO lists indoor air pollution as one of the top 10 threats to human health. When indoor ventilation conditions are poor, indoor gas pollutants accumulate and the concentration increases, resulting in serious indoor air pollution. Reverse ventilation in summer can not only cool the building, but also cool your photovoltaic panels and increase power generation.

ASHRAE  (the American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends (in its Standard 62.2-2016, "Ventilation and Acceptable Indoor Air Quality in Residential Buildings") that homes receive 0.35 air changes per hour  but not less than 15 cubic feet of air per minute (cfm) per person. as the minimum ventilation rates in residential buildings in order to provide IAQ that is acceptable to human occupants and that minimizes adverse health effects. 

Buildings in densely populated places such as stations, schools, conference rooms, shopping malls, supermarkets, restaurants, libraries, offices, gymnasiums, etc. all have mandatory ventilation requirements.

💦Dehumidification or humidification

The OSCAR solar panel in the basement can fully solve the moisture in the basement and extend the service life of the indoor structure and appliances. Basement problem: damp basement. One of the earliest signs of wetness in the basement was a stale smell. Humidity can quickly damage items stored in the basement, such as textiles, cardboard boxes or furniture. In addition, lack of regular ventilation can cause mold and harmful fungi. To make the room suitable again, it must be regularly heated, mechanically dehumidified and ventilated. In addition, the dehumidifier requires refrigeration and consumes a large amount of power. This often results in high operating costs.  The dry climate indoor can easily cause virus and bacteria to multiply and spread. In addition, the dry air takes away water from the body, making them feel dry, feverish, depressed, coughing, hoarse, and sore throat. 

Application areas

Industrial buildings, office spaces, shops, supermarkets, hotels, catering, condominiums, manufacturing facilities, warehouses, schools, workshops, hospital, scommercial buildings, airports, poultry barns, government buildings, water and sewage treatment plants, high altitude areas with thin air and for process heat applications. 

Especially industry processes that require high air flow rates: 

Welding shops, production facilities, spray booths

Dryers and drying processes

Food processing industry

Ventilation, heating, dehumidification or humidification. Solar panel with remote control LCD thermostat, provides you with a healthy climate and automatically processes indoor air. Simple operation, thoughtful air management expert! There are five modes: automatic, humidity control, manual, ventilation and heating. Can detect indoor and outdoor temperature and humidity, moisture content in the air. Multiple fan systems can be controlled at the same time. The remote control distance is 200 m.

Technical reference

① The maximum allowable building area is 15 m2 per PVT. In order to obtain higher air temperatures, the building area of 5-15 m2 per PVT is optional. The more PVT used for the same building area, the better the heating effect. Buildings with little sunlight or poor insulation; buildings with frequent occupancy or high humidity require more PVT.

② The recommended air volume for each piece of PVT is 60-100 m3/h. For buildings where the air volume exceeds, it is recommended to manually reduce the fan speed.

③ Reducing the air volume can increase the air temperature into the room. Increasing the air volume can increase the heating efficiency, thermal energy and dehumidification effect.


4. Environment friendliness: reduce the amount of air pollution and greenhouse gases that result from the use of fossil fuels for heating. Significantly reduce carbon emissions. The solar PVT cogeneration system can reduce CO₂ emissions by 88.59% compared to the traditional mains + electric heating model. In addition, compared with traditional photovoltaic modules, the carbon sequestration capacity of solar PVT modules has been greatly improved. During the entire life cycle, the carbon sequestration capacity of one square meter of PVT is 3.1 tons, which is 53.2% higher than traditional photovoltaic modules.

5. It can be assembled in multiple rows and columns according to the roof conditions, or it can be used together with other ordinary photovoltaic panels. The installation bracket is the same as the photovoltaic panel, and the installation cost is only slightly higher than that of the photovoltaic panel. POE encapsulation, extremely low water permeability, fully guarantee the life of photovoltaic panels. The photothermal equipment needs to be inspected after 10 years. Routine inspections are recommended for the photovoltaic part.

6. Intelligent operation based on indoor and outdoor temperature and humidity, no on-call operation.

Note: The solar panel cannot work in these situations: If it’s overcast, the sun isn’t shining or is shining weakly, during the night, early in the morning or late at night and when the panel is covered by snow or ice or during rain.
