Solar vacuum tube powerWhat is the power of the solar vacuum tube?
The absorption ratio of the vacuum tube is 97%. to remove the reflection of the outer tube of the vacuum tube and remove the heat dissipationThat is cloudy is 0.23KW, sunny is 0.62KW. (this data is for reference only)In addition, if it is a solar water heater, the need to multiply a coefficient 0.6.
General solar irradiance on the ground can be seen as the average number of 600-700W/m2 cloudy need to see the extent of the vagina. Sunny need to see whether there are clouds, etc. can be taken as an average of 300 cloudy, sunny day can take up to 800
The principle of solar vacuum tube is to convert solar energy into heat energy, and its power depends entirely on the solar irradiance
