Reassessment of the Indian renewable energy policy through technology implementation

Govt. of India scaled up of budget during 12
^th
five year plan for Rooftop solar project to achieve the target of 40 GWp as committed before UNFCC (United Nations Framework Convention on Climate Change). In this connection through a case study it is shown that there is a chance to reduce the target and also the space of solar project installation if a manual solar tracking based on optimum tilt angle as proposed in the study can be included in the policy for future small solar project initiatives. An equation set of monthly solar optimum tilt angle has been proposed based on an anisotropic validated model developed by FORTRAN 77 Compiler. The equation set is applicable for a wide latitude range of 13° to 39° of northern hemisphere i.e. it includes all over India. If the proposed optimum tilt based manual tracking has been adopted in Govt. policy of solar project then the target to UNFCC will be reduced to 36.5 kWp i.e. a decrease of 8.75% and the required area for solar installation will also be decreased of 8.84%.
