- Resumen
Solar thermal technology for domestic water heating is already a mature technology competitive to other conventional energy based systems. This has motivated some countries, regions or local authorities worldwide (Spain, Portugal, Italy, Chile...) to implement solar ordinances or regulations to obligate the use of solar thermal or other renewables in new and refurbished buildings. As a result, the number of solar domestic water heating systems has increased considerably during the last years. Only in Spain a total collector surface of 3.500.000 is installed corresponding to 2,4 GWth.
Practical experience, however, has shown as an important part of the domestic water heating systems in the Spanish market are not performing appropriately resulting into reduced solar energy savings and bad reputation of the solar thermal technology.
Furthermore, many of the systems owners have no enough information about the benefits of their installation. This results into a lack of interest on establish maintenance contracts with solar professionals and companies.
To solve this situation, there is a need of new low-cost methods and solutions to support maintenance and operation of these systems.
Smart metering systems to support maintenance and operation are already available in the market. They are used by big technical service providers in commercial and institutional buildings. However, they have not been designed to specifically address the niche market of solar domestic hot water systems. They are too expensive, and the specific technical requirements of these systems are not fulfilled.
In this thesis, a new low cost smart metering kit to support operation and maintenance of solar domestic hot water systems has been developed. The kit integrates advanced ICT techniques with smart metering procedures for thermal energy counting.
The commercial name for the new smart metering kit is SeYe. Most relevant innovations have been published in a Spanish patent (P201630319) and in the conference articles “"Open data solar thermal meter for smart citie" and “"Comparative experimental analysis of solar thermal energy counters" presented at the ISES Eurosun Conference 2016.
The kit has already been installed in 70 plants located nearby Barcelona which were not producing as expected. With the use of SeYe these plants are now properly operated and maintained assuring proper performance.
