Problems solved by technology

[0002] Solar panels are the most important functional components of solar power generation. Most solar panels do not require heat behind them. However, due to incomplete heat absorption and low conversion rate of sunlight in solar panels, a lot of heat is often conducted from solar cells to the back of solar panels. The backplane, causing the temperature of the backplane to be too high, transmits heat to the room, affecting people's work and life

Abstract

The invention discloses heat-insulation coating for solar panels, and can be applied to the field of production of heat-insulation coating for solar panels. The heat-insulation coating comprises, by weight, 85-90 parts of base material, 6-10 parts of functional fillers and 1-3 parts of auxiliaries. The base material is silicone acrylic emulsion. According to the scheme, the heat-insulation coatinghas the advantages that excellent effects of reflecting and dissipating light and heat can be realized by material compositions of the heat-insulation coating, and accordingly the surface temperatures of coated objects can be lowered to a great extent; temperature difference contraction deformation due to heat stress of structures can be reduced, and the crack resistance, the impermeability and the durability of the structures can be improved; heat which is transmitted into indoor environments from roofs and exterior walls can be obviously reduced, accordingly, the heat comfort of environments can be improved, and energy can be saved.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a thermal insulation coating for solar panels. Background technique [0002] Solar panels are the most important functional components of solar power generation. Most solar panels do not require heat behind them. However, due to incomplete heat absorption and low conversion rate of sunlight in solar panels, a lot of heat is often conducted from solar cells to the back of solar panels. The backplane will cause the temperature of the backplane to be too high, and the heat will be transmitted to the room, affecting people's work and life. [0003] Therefore, it is necessary to insulate between the solar backplane and the solar cells to provide protection for the temperature behind the solar panels. Contents of the invention [0004] In view of the above problems, it is necessary to provide a technical solution that can deal with it. [0005] The object of the present invention is to ...
