The purpose of this study is to make a comparison between the solar powers thatwe can subtract using solar panels in two different locations: Iasi, Romania and Patras,Greece. The considerations in this project were based on the values obtained using acomputer program called Meteonorm witch was designed to provide useful weatherforecasts for different months, days or hours. As most of the people would also assume, Ithought in the beginning that the two values would be totally different and that the solarpower witch can be used in Greece has much bigger values than the one in Romania. Well,as it seems, my assumptions were incorrect and hopefully the values obtained from thisresearch project will bring some benefits to the Romanian people regarding the matter ofusing the solar power, a free source of power, which does not pollute and which is usedworldwide with great success and multiple future economical advantages.
