An analysis of ground-based observations of solar irradiance was recently published in this journal, reporting an apparent increase of solar irradiance on the ground of the order of 1% between solar minima and maxima [1]. Since the corresponding variations in total solar irradiance on top of the atmosphere are accurately determined from satellite observations to be of the order of 0.1% only [2]...

Monsoon is the major manifestation of the seasonal cycle in the tropical regions, and there is a wide range of evidence from marine and terrestrial data that monsoon characteristics are affected by changes in the Earth’s orbital parameters. We consider 3 periods in the Eemian and 3 in the Holocene that present some analogy in the Earth’s orbital configuration in terms of obliquity and precessio...

Efficiency of the PV module can be improved by operating at its peak power point so that the maximum power can be delivered to the load under varying environmental conditions. This paper is mainly focused on the maximum power point tracking of solar photovoltaic array (PV) under non uniform insolation conditions. A maximum power point tracker (MPPT) is used for extracting the maximum power from...

This paper presents the integration of urban planning techniques considering sunlight access to an existing simulator of urban plots building potential, BlockMagic. Insolation can be simulated along with Master Plans rules, aiming at maximizing both building potential and sunlight access.

Attached to this letter, please find an insolation sensitivity study of the HI-STORM EHT thermal model for PFS. We trust that the above information fulfills the verbal commitment made by us in an earlier telecon.

The discovery of planets orbiting double stars at close distances has sparked increasing scientific interest in determining whether Earth-analogues can remain habitable in such environments and how their atmospheric dynamics is influenced by the rapidly changing insolation. In this work we present results of the first three-dimensional numerical experiments of a water-rich planet orbiting a dou...

A better performance of photovoltaic (PV) generator is obtainedat high insolation. But at high insulation, the temperature of the PV system increases and leads to the drop down of the performance of the system making the system unable to supply the load. The problem becomes more difficult with irregular solar insolation, the system experience variation in his output, which is not good for the u...

"777 oil" is a code drug of the Siddha system of medicine used in the treatment of Psoriasis. The drug is derived from the leaves Wrightia tinctoria by insolation, with coconut oil as base. The present study is aimed at comparing the drug prepared by insolation with that prepared in darkness.Analytical studies carried out in both the drugs showed difference in acid number without exposing to su...
