What are the problems with the use and promotion of solar water heating systems

What are the problems with the use and promotion of solar water heating systems?

Solar water heating system (heater) is recognized as a relatively mature energy-saving product, and residents are happy to use it. However, it is actually difficult to promote in cities. The proportion of residential solar water heaters is still very low. The main problems are as follows: 1. The vast majority of solar water heating systems

Which five regions are China's solar energy resources divided into

Which five regions are China’s solar energy resources divided into?

In order to make better use of solar energy in accordance with the different conditions of each region, Chinese researchers in the 1980s divided the country into the following five types of regions according to the total amount of solar radiation received by each region. 1. First-class area The annual sunshine hours are 3200~3300h. The

Solar energy utilization and energy crisis and environmental issues

Basic way of using solar energy The basic ways of using solar energy can be divided into the following four categories. 1. Light and heat utilization Its basic principle is to collect solar radiant energy and convert it into heat energy through interaction with matter for use. At present, the most used solar energy collectors
