Have you seen the DNI calculator on our website designed for India? Basically what you want to know is the DNI of the area which stands for Direct Normal Iradiation received per unit area by a surface that is always held perpendicular (or normal) to the rays that come in a straight line from the direction of the sun at its current position in the sky. Go to our Solar Calculator section in Free Web tools and use DNI finder. Cost associated with DNI is varied. We get a lot of questions asking the cost but there is not way I can tell you the cost. Do you want to know cost of solar panels per square feet? Ratio of solar panel area and cost? Well that will depend largely on the efficiency and type of solar panels used. Thin films for example need much more area to produce the same energy as a poly crystalline panel. Please be more specific when asking costs. Hope I have answered your query.
