What is the period of a solar collector?

Therefore, the period, which starts when the heat collection exceeds 0, is defined as the available operating time of collector operation. Furthermore, the solar energy, which is irradiated on the collector surface, is the effective radiation energy within the effective operation time of the collector.

How many square meters do solar collectors produce a year?

The annual output of solar collectors is 60,000 square meters. During the past 6 years, SolAqua solar collectors have been approved by the six top international authoritative certifications, have got two utility model patents, and passed the ISO9000-2015 quality management system certification.

Are solar heating systems becoming more popular in China?

In 2018, the new built area used by all solar heating systems in China totaled 3726 million m 2, which underlines that solar energy usage has significantly expanded from individual solar hot-water installations to large scale solar-heating fields [ 1 ]. Solar-heating systems will likely continue to increase in popularity over the next few years.

How does solar irradiance affect the efficiency of a collector system?

Subsequently, with increasing solar irradiance, the collector system enters the effective operation state. The instantaneous efficiency of the collector increases rapidly from 8:00 to 10:00, and the collectors run from 10:00 to 16:00 with high efficiency. The inlet and outlet temperatures of the collector continue to increase.

Do flat-plate solar collectors improve thermal performance?

The thermal performance of flat-plate solar collectors (FPSCs) depends not only on environmental and operational parameters but also on its dimensions. In this study, the thermal performance improvement mechanism of FPSCs is studied focusing on the impact of collector size.
