Testing and analyzing of solar energy resource

The solar energy resource of two typical areas was tested by taking advantage of different instruments from home and abroad in Inner Mongolia. Compared the actually tested data with satellite data from National Aeronautics and Space Administration, energy cost was estimated in different solar energy resource conditions through the use of RETScreen project analysis software form Canada. Analysis results show that acquisition of accurate data is the precondition of solar energy resource assessment and difference of solar energy resource assessment outcome will bring to important impact to energy cost.
