The increasing population density which happened in Java Island as central of government, education, social and politics is caused by inequality distribution of population. Those are led to bump the vital needs, one of them is eletric current. Electric energy wtih the new and renewable resources has not yet reach the optimization, one of them is solar energy. The mapping of solar power energy generator potential is needed for accelerate identification potential areas.The purpose of reasearch is get distribution solar power energy generator location with remote sensing and GIS. The methods which will be used are classification method, overlay, scoring and weighting each parameters. Parameters which is used are monthly rainfall accumulation, monthly average cloud distribution, land surface temperature class map, land use map, and slope map. Determination of solar power energy generator potential on chosen regency is computed by weighting land surface temperature parameter, land use and landslide in 4 classes potential.These classes were defined very low potential, low potential, medium potential, and high potential.Based on monthly rainfall accumulation and cloud distribution overlay are resulted 4 regencies with drought month and most cloud free area Gresik, Lamongan, Rembang, and Sampang regency. From the rainfall accumulation, Rembang regency is the lowest rainfall accumulation on one year periode. Spatial analysis, weighting addition, and also scoring on land surface temperature, land use and land slide are done only on Rembang regency. The results are 2,085.153Ha or 2 % very low potential area, 70,877.295 Ha or 69% low potential area, 3,509.407Ha or 3% medium potential area, 27,162.458 Ha or 26% high potential area.
