Problems solved by technology

However, due to the low heat flux density of solar energy, it is greatly affected by seasons and weather. In rainy days and winter, solar water heaters often need electric auxiliary heating.
In terms of building heating, the traditional solar system is difficult to meet all-weather heating, and the large heating load makes the system bulky
All of these make the application of solar direct heat utilization system subject to certain restrictions.
