Product Description
Photovoltaic glass high reflection white enamel
BJ-HP1-8W is a lead-free water-based environmentally friendly highly reflective white coated enamel. specially developed for use on the back panel glass of photovoltaic double glass modules.
The product has passed the performance test, the certification issued by the National Photovoltaic Quality Inspection Center. The product has excellent high reflectivity, which can effectively improve the power generation efficiency of photovoltaic modules. The product composition does not contain heavy metal lead, and the use of water-based enamel medium oil meets various environmental protection requirements.

The principle of high reflection white enamel to improve the power generation efficiency of photovoltaic modules
Crystalline silicon solar cell modules are composed of glass, EVA or PVB, cells, back panels, frames and other materials. They are packaged into a "sandwich" structure in the order of glass-EVA-cell-EVA-back panel glass, the structural diagram as shown in Figure 4.
Figure 4 Diagram of the battery module structure
Fig. 5 Schematic diagram of double-glass optics
Optical diagram of the double glass component as shown in Figure 5. Most of the incident light shines through the front and back panel glass onto the cells. A small part is projected from the gap between the cells onto the back panel glass, and if the back panel glass is not coated in anything, the light directly penetrates the back panel glass, causing a loss of light. Coat the back panel glass with a layer of highly reflective white enamel.
The enamel coating will re-reflect the light through the gap to the cell, so make full use of the light energy, and the power generation efficiency of the battery module can be increased by 3% to 6%.

- Composition and characteristics of BJ-HP1-8W high reflection enamel
- Glass flux is an important part of the enamel, mainly composed of a variety of inorganic non-metallic minerals and chemical raw materials, etc.,
- Functional whitening powders usually use titanium dioxide as the main raw material. In the case of a harsh outdoor environment, solar photovoltaic modules need to ensure a service life of 25 years, so our company only use the best titanium dioxide as our raw materails
- Water-soluble medium oil is composed of polymer resin and solvent, and the additives include dispersants, defoamers, leveling agents, thickeners and curing agents. Our company uses water-soluble environmentally friendly resins, and makes the enamel have good printing performance and good adhesion.
