Solar basics_Zhejiang Hurras Solar Energy Technology Co., Ltd.
The typical household uses 10,000 to 15,000 BTUs of hot water per person per day. A 20 vacuum tube solar collector can produce 30,000 BTUs on a summer day with a footprint on a roof of only 36 square feet. The system can provide 100% of summer hot water needs and depending upon regional weather 30% of winter needs. Solar domestic water heating can greatly reduce carbon dioxide emissions- the cause of global climate change. Technology Supported by: Hangzhou Chuangyi Science and Technic Company(EC-world).
Installation_Zhejiang Hurras Solar Energy Technology Co., Ltd.
The angle and direction of installation is also of great importance as it will effect the efficiency of the solar collector. Naturally you want the collector to receive the maximum amount of sunlight each day and throughout the year. As a general rule if you are in the Northern Hemisphere then the collector should face South and if you are in the Southern Hemisphere then the collector should face North. See diagram below. You do not have to be too careful about mounting the collector at the exact angle s...
