Meanwhile, 160 m 2 evacuated-tube solar collectors, a solar heat storage water tank and two circulating water pumps were located on the roof of the building, while the other components of this system were placed in an equipment room on the first floor, as shown in Fig. 2. A prepared PCM with a latent heat of 262 kJ/kg and phase-change temperature of 113
In addition, the collectors will prove useful especially in those buildings where the use of water is significant and generates huge consumption costs. Therefore, they will be useful in public buildings, sports facilities or residential houses. Solar collectors acquire natural solar energy, providing an independent energy resource to the
A recent paper by Ferroni and Hopkirk (2016) asserts that the ERoEI (also referred to as EROI) of photovoltaic (PV) systems is so low that they actually act as net energy sinks, rather than delivering energy to society. Such claim, if accurate, would call into question many energy investment decisions. In the same paper, a comparison is also drawn between
Parabolic trough solar collectors are also reliable and have a long lifespan. They are not as susceptible to weather damage as other types of solar collectors, such as photovoltaic panels. However
Space saving. Compared to solar panels, solar collectors use little space on your roof. Solar panels use up to 10m2 of your roof while collectors use only 2m2 or 3m2. High-efficiency rates and can convert up to 90% of the sun it traps in the collector. Businesses can benefit more from solar collectors than solar PV panels. Reduce carbon footprint

An investigation between the flat plate and evacuated tube solar collectors was done from the economic point of view feasibility. It was determined that the investment return period was 9 years
Considering the total cost (Equipment plus operation) of a non-solar collector system, the return on investment (ROI) was calculated for both evacuated tube and flat plate
The most suitable scenario, which is a high solar fraction, has a price of $ 0.012 per kWh of generated heat and a return on investment (ROI) of 5.1 years. The reason for this high return on investment is the low price of electricity in Iraq (0.027 $/kWh), also it can be decreased by reducing the total investment value.
Milani et al. [4] applied evacuated tube collectors (ETCs) in solar water heaters (SWHs) on four major Australian cities. They investigated the role of using a diffuse flat reflector (DFR) at the back of ETC array to improve the heat capture rate. They showed that this model may increase the annual energy saving up to 95.8% for zone 1; 91.3% for zone 2; 81% for

This type of solar collector utilizes long parabolic-shaped reflectors to collect the sun''s radiation and concentrate the sunlight on a receiver pipe that runs down into a long trough. Line-focus solar collectors are very
Solar collectors are energy harvesting devices that convert solar radiation into heat energy and transport the generated heat via a working fluid (heat transfer fluid) in a riser pipe to a storage tank [21], [22].The solar energy transported by the working fluid can also be utilised directly for space heating, equipment conditioning and other thermomechanical applications [23].

Recent papers argue that the energy return on energy invested (EROI) for renewable electricity technologies and systems may be so low that the transition from fossil fuelled to renewable electricity may displace investment in other important economic sectors. For the case of large-scale electricity supply, we draw upon insights from Net Energy Analysis and
