The Integrated Collector Storage (ICS) has a great application in the solar energy field such as instantaneous heating with little initial and operation cost as well as its resistance against the problems of overheating and freezing. In this research, an advanced ICS was designed and investigated with an array of 1.5 mm thickness galvanized lateral steel plate fins fixed in the storage tank. The new design was examined from 7:00 a.m. until 5:00 p.m. The results show an increase in mean storage temperature and collection efficiency of up to 20% and 37% respectively

And Performance

A detachable, automotive solar system for water and passenger compartment heating is developed. The study shows that an adjustable 1 m2 solar collector is sufficient to satisfy the needs of a small group during a short camping trip in Saudi Arabia desert. Also it is found that an adequate water temperature in the storage tank, due to ambient solar heating, is maintained in all cold months, except December when it is insufficient. Among the advantages of the system is its entire operation on renewable solar energy and its ability to heat the car compartment whenever the heated water reaches the required temperature and solar energy is still available.

The Impact

Thermal solar systems are interesting solutions to reduce CO 2 emissions and gradually promote the use of renewable sources. However, sizing such systems and analysing their behavior are still challenging issues, especially for the trade-off between useful solar energy maximization and stagnation risk minimization. The new EPB (Energy Performance of Buildings) standard EN 15316-4-3:2017 offers several methods to evaluate the performance of a forced circulation solar system. One of them is a dynamic hourly method that must be used together with EN 15316-5:2017 for the simulation of the stratified storage tank connected with the solar loop. In this work, such dynamic hourly method is extended to provide more realistic predictions. In particular, modeling of the pump operation due to solar fluid temperature exceeding a set threshold, or due to low temperature differential between solar field and storage tank, is introduced as an on–off control. The implemented code is applied to a case study of solar system for the preparation of domestic hot water and the impact of different design parameters is evaluated. The model predicts a higher risk of overtemperature lock-out or stagnation when the solar field surface is increased, the storage volume is reduced and water consumption is set to zero to simulate summer vacation periods. Finally, a simple modulating control with a time step of a few seconds to a few minutes is introduced, quantitatively showing the resulting benefits in terms of useful solar energy increase, back-up operation savings and reduced auxiliary energy use.

— In the present work, a 1 m2 solar gel pond was fabricated and tested. Experiments were performed on a 1.0 m2 Solar Gel Pond area at Karaikal, Pondicherry, India (Latitude 10.55° N & Longitudinal 79.52° E). The experimental investigation were carried out in to study the influence of Upper Gel layer thickness (UGL), Salinity of Lower Convective Storage Zone (LCSZ), Depth of LCSZ on the storage temperature of the solar gel pond. The maximum storage temperature of 65.5 °C was achieved in a span of 15 days. Keywords—solar gel pond, polymer gel, storage temperature, solar energy
