The non cracked water-based PVT photovoltaic thermal module equipment is a product that comprehensively utilizes solar energy. PVT refers to the combination of photovoltaics and thermal. Photovoltaic technology converts solar radiation into electrical energy, while photothermal technology converts solar radiation into thermal energy. PVT photovoltaic thermal modules combine these two methods to achieve dual utilization of solar energy.
The PVT photovoltaic thermal module consists of glass, solar cells EVA, the insulation board, adhesive film, heat exchange substrate, flame retardant insulation, and frame back plate layered together. The upper layer of glass and battery cells achieve photovoltaic power generation, while the middle layer of heat exchange substrate recovers battery waste heat for heat utilization. Each layer is designed with adhesion, insulation, flame retardant insulation, etc., and has both power generation and heating functions, improving the comprehensive energy utilization efficiency.
Adopting an integrated pressure bearing process, the components and heat exchange backplate are formed under pressure in one go, completely avoiding hidden cracks in photovoltaic silicon wafers.
It can adapt to all day operating environments from -40 ℃ to 80 ℃, effectively solving the problems of expansion stability and deformation of components made of different materials, and ensuring that photovoltaic silicon wafers have no hidden cracks during operation.
The flow channel is optimized by fluid mechanics and formed flexibly in one go, achieving integrated heat absorption and transfer; Fast circulation, low thermal resistance, high heat transfer efficiency, same flow path and balanced flow rate; The heat exchange area is 2.2 times the daylighting area, making it the largest heat collection and heat transfer ratio and highest thermal conductivity heat transfer backplate in the current solar thermal utilization industry.
The full channel heat exchange substrate is made of ultra pure ferritic stainless steel (specially designed for water treatment), with high thermal conductivity, stability, good plasticity, strong toughness, high wear resistance, high fatigue strength, high temperature resistance, corrosion resistance and other characteristics; At temperatures above 200 ℃, it maintains its original structure and has a lifespan of up to 25 years, which is consistent with the lifespan of photovoltaic modules.

Photovoltaic Thermal Integrated Machine PVT is a new product that utilizes solar energy to provide both photovoltaic power generation and hot water.
The photovoltaic solar thermal integrated machine PVT is mainly used in occasions that require hot water, such as hotels, hospitals, school dormitories, nursing homes, high-end residences, and so on.
Usually, the thermal conductive medium of photovoltaic solar thermal integrated machine PVT is antifreeze, mainly composed of alcohol compounds (antifreeze matrix) and corrosion inhibitors (anti metal corrosion).
In terms of sales price, the photovoltaic solar thermal integrated machine PVT is higher than single photovoltaic products and single flat plate collector products. However, the comprehensive solar energy conversion rate of the photovoltaic solar thermal integrated machine PVT is greater than 85%, far higher than the conversion rate of a single photovoltaic product of about 25%, and also far higher than the conversion rate of a single flat plate collector product of about 50%; At the same time, by utilizing the same light receiving area, the photovoltaic thermal integrated machine PVT achieves dual benefits of photovoltaic power generation and hot water, shortening the investment payback period compared to a single solar product.
