A modified empirical correlation for estimating monthly mean daily global solar radiation on a horizontal surface is obtained by using meteorological parameters, viz hours of bright sunshine, monthly mean daily maximum temperature, relative humidity, and daily M.S.L and vapour pressure. The suggested modified equations (11) and (12) are tested for their applicability to State of Bahrain. The results show an excellent agreement between the measured values of monthly global solar radiation and the estimated values obtained from these equations. The average percentage error for the two equations is 4.3% and 4.6% respectively. The two modified models are recommended to be used for Bahrain.","PeriodicalId":162029,"journal":{"name":"International Journal of Solar Energy","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131523634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, it is imperative to have precise knowledge of the concentrated flux pattern on the outer surface of the absorbing tube. The existing methods in literature are very general and the consequent expertise and computation facilities required to exercise them may prevent their use by the design engineers in industry. In the present paper, a simple but reliable analytical method is developed which enables the determination of the concentrated flux distribution on the outer surface of the absorber tube of a PTC. Both defaults resulting from contours and sun tracking are considered in the analysis. A case study for a site having a latitude angle of 31°N is presented.

In the budget period 1993-94, the Commission has provided approximately 20 Mio ECU (23 Mio US Dollars) for system development, demonstration projects and regional integration. This represents about 50% of the Commission's total spending on photovoltaics.

It was found that concrete solar collector with galvanized steel pipes was as good as local metallic conventional collectors with a daily efficiency as high as 40% compared with 45% for the local metallic conventional one. The time constants for concrete collectors investigated are much higher than metallic collectors, with the value as high as 37.4 minutes.","PeriodicalId":162029,"journal":{"name":"International Journal of Solar Energy","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130606047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
