I live in Phoenix where the sun shines all the time and I see all these rooftops. Very Very few with any sort of solar panels. WHY? It easy, there is no pay back. IE. SOLAR IS NOT YET ECONOMICAL. But... it is getting better.
Nice article. Lots have been said about solar market. Unless there is a strong approach from business houses and governments towards making solar as first choice or atleast supporting the growth of solar industry, we will see ups and down in its business.
