The performance of a roof mounted grid-connected photovoltaic (PV) system in Northern Ireland was monitored over 3 years on annual, seasonal and monthly bases. The overall system performance was adversely affected by low insolation conditions; 19% of total incident insolation was absorbed at irradiance level below 200 W/m 2 and 67% below 600 W/m 2 , only 6Á2% above 900 W/m 2 . In summer and winter, the PV and system efficiencies were 9Á0 and 8Á5%, and 7Á8 and 7Á5%, respectively and inverter efficiencies were 86Á8 and 85Á8%, respectively. The inverter for this particular system was oversized; 77% of the total DC energy produced when inverter's operating load was 50% of its rated capacity. The annual average monthly system performance ratio (PR) was 0Á61 with seasonal variation 0Á59 to 0Á63. The average monthly PV, system and inverter efficiencies over the whole monitored period were 8Á8, 7Á6 and 86Á8%, respectively. The main losses of the system were inverter DC/AC conversion loss, inverter threshold loss and low insolation loss.

“…sealant deterioration would cause leaking) as it may compromise their structural continuity). BIPV modules can extend up to the highest temperatures of between 44 and 50 °C during the day (Fung and Yang, 2008; Chow et al , 2009; Ye et al , 2013; Tina et al , 2013) which can lead to a substantial decline in its performance and efficiency (Iliceto and Vigotti, 1998; Kato et al , 2002; Sugiura et al , 2003; Mondol et al , 2007). Some studies have reported that occupants sitting near windows where BIPV systems are installed often experience thermal discomfort or rather a slightly uncomfortable but acceptable condition (Tian et al , 2007, 2013, 2013).…”

PurposeThe maintenance of green building technologies such as building-integrated photovoltaic (BIPV) is a challenge due to the non-existence of maintainability considerations during the design stage. This led to building defects which accounts to high expenditures throughout the building's lifecycle. The use of BIPV in buildings is an emergent trend, and further research is requisite for their maintainability. This paper assesses the performance and maintainability of BIPV façade applications based on the green maintainability design considerations.Design/methodology/approachQualitative method is undertaken in this study, which includes field surveys, instrumental case studies and stakeholder interviews to probe the issues linked with the BIPV's maintainability.FindingsFindings have shown some technical defects discovered in BIPV applications in tropical areas, as well as issues on cost, aesthetics and implementation are the main causes for the low adoption of BIPV in Singapore.Originality/valueUnderstanding the research outcomes will embolden designers and allied professionals to team up in ensuring the long-term maintainability and sustainability of green building technologies. This research gives recent and important information in the design, installation and maintainability of BIPV, as well as good practices that would add value to facilities management and to the design of green building technologies.

“…High cell temperature impairs the conversion efficiency of silicon cells. Iliceto and Vigotti [11] investigated a large PV power plant and summarized factors causing PV conversion loss. The temperature dependence of the solar cell performance was identified as one of the most important characteristics affecting the power output with losses up to 7.6%.…”

A numerical and experimental analysis of an integrated TEG-PCM power enhancement system for photovoltaic cells

Solar photovoltaic (PV) cells especially crystal silicon cells have witnessed a soaring installed capacity during past years. Research efforts have been made to increase the PV conversion efficiency and one direction is towards the cooling of PV systems since a higher PV temperature impairs its conversion efficiency. Phase change materials (PCM) capable of storing large amounts of latent heat are found to be effective on cooling PV cells while thermoelectric generators (TEG) which are solid waste heat converters can be used for converting the heat from PV into electricity. Therefore, this research investigates the concept of an integrated thermoelectric PCM system to enhance the PV efficiency. Theoretical investigations found that the TEGs had small power output due to small temperature difference under natural convection conditions. However, PCM was effective on hampering PV temperature increase during heat storage process. This research developed a numerical model for thermal simulations of the integrated system and has been validated by experimental results. The effect of various PCM thicknesses, conductivities and phase change temperatures were evaluated. The simulation results stressed the importance of high PCM conductivity for a thick PCM layer to reduce its insulation effect on the TEG and PV layers. Finally, the best thermal performance for the PV/TEG/PCM system was achieved with a 50 mm thick PCM layer with thermal conductivity of 5 W/mK and a phase change temperature of 40-45 °C. Further optimisation and experimental evaluation are however being recommended towards the establishment of the full technical and scientific boundaries.
