specific Embodiment approach 1

[0023] Embodiment 1: In this embodiment, a reflective coating for increasing the photoelectric conversion efficiency of a roof distributed photovoltaic power generation system includes emulsion, solvent, reflective pigments and fillers, dispersants, defoamers and film-forming aids;

[0024] The reflective pigments and fillers are one or a mixture of titanium dioxide, rutile titanium dioxide, hollow glass microspheres and far-infrared ceramic micropowders.

[0025] The reflective coating described in this specific embodiment is coated on the roof to form a coating and matched with photovoltaic power generation to form a high solar reflection coating, which can reflect sunlight more effectively than the waterproof layer. The roof temperature can be kept within the optimal operating temperature range of the photovoltaic power generation system, and it helps more sunlight to be emitted to the solar panels, increasing the efficiency of photovoltaic power generation and prolonging th...

specific Embodiment approach 2

[0034] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the reflective paint includes 5 to 50 parts of emulsion, 5 to 45 parts of solvent, 5 to 50 parts of reflective paint in parts by weight. Filler, 0.1-5 parts of dispersant, 0.1-5 parts of defoamer and 0.1-5 parts of film-forming aid. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0035] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the particle size of the reflective pigments and fillers is 10 nm to 50000 nm. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a coating and an application, and provides a reflection type coating capable of increasing photoelectric conversion efficiency of a roof distribution type photovoltaic power generation system and an application. The problems that photoelectric conversion efficiency of existing photovoltaic power generation is low, the service life of a photovoltaic inverter is short and generating capacity is affected are solved. The reflection type coating is prepared from emulsion, a solvent, reflection type pigment and filler, a dispersing agent, a defoaming agent and a coalescing agent. The invention provides the application of the reflection type coating to increase of the photoelectric conversion efficiency of the roof distribution type photovoltaic power generation system. The reflection type coating is used for increasing the photoelectric conversion efficiency of the roof distribution type photovoltaic power generation system.

Description

technical field [0001] The present invention relates to a coating and its application. Background technique [0002] According to the 2018 national power industry statistics released by the National Energy Administration, as of 2018, grid-connected solar energy was 174.63GW. Among them, 44.38GW of new solar energy was installed in 2018, a year-on-year decrease of 18%, centralized about 23GW, a year-on-year decrease of 31%, and distributed about 20GW, a year-on-year increase of 5%. The distributed photovoltaic industry is increasing. [0003] Problems faced by roof distributed photovoltaics: [0004] 1. Low efficiency and long payback period. For example, polysilicon photovoltaic modules decay by 2.5% in the first year, and then decrease by 0.7% year by year. [0005] 2. When the temperature of photovoltaic modules is too high, the photoelectric conversion rate of solar cells will decrease, and the service life of electronic components will also be reduced. [0006] 3. Th...
