The use of solar energy is now moving into new frontiers, some as varied as illuminating the billboards. Perhaps the sun is becoming brighter as the day progresses more so in the rural landscapes and lately within the urban ambiences too. The moot question that remains is whether there is a compulsive need to use solar energy for urban uses like advertising?

Wind energy continues to be the dominant source of renewable power in India. About 8000 MW of wind power capacity has been installed in the country so far. As against this, the share of solar power is abysmally low mainly due to its high initial capital cost and thus, a higher cost of per unit power generation.
