| Summary: | This paper particularly looks into the trending of actual solar radiation values over the past years as well as the annual trending of the parameters experienced in Malaysia and weighs out the possibilities in amending this value to suit the actual current weather at different periods of the year to achieve a more practical or suitable rating. Monthly median values of the solar radiation are evaluated and analysed for the past several years' occurrences. The approach is to look at either increasing or decreasing the value for solar radiation parameter if the evaluated median solar radiation values proves to be oppositely below or above the assigned value, respectively. Worst case environmental conditions like high solar radiation levels on which the current conservative parameter assumptions are premised could happen only for a few days per year. On top of that, the period of year which has high solar radiation are separated from the periods which has low solar radiation to acquire a more flexible line rating that better suits the weather conditions at different months. |
