This method is also proposed for correcting the experimental results gathered using noncalibrated Eppley-type pyranometer. The procedure starts by determining two daily distributions of clear sky solar radiation at the studied location. One of these distributions is constructed using measurements by an accurate instrument used as reference for this purpose, while the other one is based on the actinograph or/and noncalibrated Eppley-type pyranometer in use. The correction factor can be deduced then by relating these two distributions with taking into consideration climatic conditions and life-time behaviour of the instruments. The obtained correction factor is found to be highly dependent on the ambient te...","PeriodicalId":162029,"journal":{"name":"International Journal of Solar Energy","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114943418","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}

The total installed European capacity 5 years ago was limited to a few hundred MW while at the end of this year 1995, it will exceed 2000 MW. At the same time quality was dramatically improved: the specific energy harvested by the best machines increased over the last ten years from 1000 kWh m2 a\"1 to about 1700 kWh m-1 a-1. In Europe operating turbines produced on average 1700 kWh per kW in 1994 against only 580 kWh per kW in 1986. Prices on the other hand have come down and are currently slipping below 900ECU/kW for turn key installations. Germany has the largest installed capacity due to favourable federal regulation of the supply tariffs for renewable electricity to the grids. Germany also leads technological innovation in wind energy. Europe is strongly involved in the exploitation of wind energy overseas as well, e.g. in India, China, Egypt. The European Commission occupies a leading position in technological development.

The result shows that Angstrom relations are valid for Ethiopian locations, and the correlation equations can be used to predict the monthly mean daily global solar radiation in the locations considered in this study. This study also proves that the results made by ENEC et al, using the generalised Frere's coefficients, is unsatisfactory for the prediction of monthly mean daily global solar radiation. On the other hand, the work of Dogniaux and Lemoine, using the regression coefficients a and b as a function of latitude and atmospheric turbidity and grouping large range latitudes to extend the application, can give better estimation.

The models selected for discussion, applicability, and comparisons are the model suggested by Liu and Jordan dated 1962, the model of Klein dated 1977, and the model of Klein and Theilacker dated 1981. All these three models are applied, tested and compared for their reliability. The comparative study of the models shows that all these models are rather accurate for locations in Greece. But it seems that the Klein and Theilacker's analytical method for estimating leads to better results, values calculated in this manner and through the other methods are compared. Therefore, the above three models are used to estimate global solar irradiation for one location on surfaces of various tilt angles and azimuths, and the results are presented and discussed.","PeriodicalId":162029,"journal":{"name":"International Journal of Solar Energy","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131584358","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}

The value of the rated MW energy absorbed by an external cylindrical receiver, is investigated, and its relations to the tower height, the site location and the field radius are given. The effect of changing the radial spacing on the rated MW and the total number of heliostats in the field is also computed and depicted.

A proper matching of electromechanical loads to a PV array is a great problem in many PV systems. This is mainly related to the non-linear, solar irradiance and cell temperature-dependent voltage and current characteristics of the PV array generator. In a proper matching system, the electrical energy supplied to the load is close to the maximum available array energy. The load matching factor is one of the basic comparison method used in the optimisation of PV water pumping systems. Optimisation of PV pumping system can be made from a simple non-linear mathematical model and from experimental data. From this optimisation technique, array configuration can be determined using the required rated power of the motor/pump subsystem and the I-V characteristic of a single cell. Conversely, the optimal size of motor/pump subsystem can be determined from a known array configuration. ...","PeriodicalId":162029,"journal":{"name":"International Journal of Solar Energy","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130178954","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}

It is found that Solar Hybrid system is a better option than Solar Alone and the cost of power generation is competitive with conventional means.
