As the world’s power demand is increases photovoltaic power supply to the utility grid is gaining more and more visibility. The user wants to utilize maximum solar power of an array by operating the photovoltaic array at it’s highest energy conversion output. The electrical design considerations due to varying nature of the solar power generated resulting from unpredictable and sudden changes i...

In this work we present the analysis of the geomagnetic field fluctuations observed at different ground stations (approximately along two latitudinal arrays, separated by several hours in local time) during the passage at the Earth’s orbit of the tail of the 15–16 July 2000 coronal ejecta. The time interval of interest is characterized by northward interplanetary magnetic field conditions and s...

Investigations of snowcover dynamics beneath vegetation canopies require either measured or estimated solar and thermal radiation values at the snow surface. A deterministic method is presented that uses portable arrays of pyranometers and pyrgeometers to quantify the amount of incoming radiation at the snow surface. Example solar and thermal radiation datasets are presented from boreal deciduo...

The concept of collecting solar power in space and transmitting it to the Earth using microwaves has been studied by numerous researchers in the past. The Space Solar Power Initiative (SSPI) at Caltech is a collaborative project to bring about the scientific and technological innovations necessary for enabling a spacebased solar power system. The proposed system comprises an array of ultra-ligh...
