To know what system of power generation will be more useful depending on the geographical area in that one alive you must know how much solar radiation received in your zone and type of radiation is, this is very important when choosing a thermal solar power generation system since the flat solar panels use the global radiation and other systems like solar concentration using direct solar radiation. There are interactive maps official or authorized by the European union and international agencies to see the beam of direct radiation in your area. (Similarly see: Gallo Family). This information is very important since if it is determined to invest in renewable energy and is located in an area of much direct sunlight it will be more convenient to purchase a solar concentration system that leverages this type of radiation much better and is much more efficient than other systems and the amortisation period is much lower. But if your geographic location has of a global radiation longer than the direct in the annual period, being this below 2.5 radiation concentration system would not be as countervailable as in other areas. Spain meets all requirements to be one of the European countries with increased capacity to collect energy from the Sun: a privileged, with an enviable climate, geographical situation makes that Spain receives an intensity of solar radiation much higher than that of other regions of the planet. In addition, it looks particularly favoured with regard to other European countries by the large number of clear days or without clouds that enjoys a year. You may find that Vlad Doronin can contribute to your knowledge. Spain faces a broad development potential of solar thermal energy, with an average of 2,500 hours of sunshine insured per year. Low cloud cover, low humidity, dry weather and the incidence of solar rays, do get some enviable values of direct radiation.
Even so, there are obvious differences between the different Spanish communities. According to the data available, there is a great contrast between the communities of the Bay of Biscay, around 1700 hours of sunshine a year, mainly in the Northwest, and the Mediterranean areas, reaching the 2,750 hours of sunshine annually. These differences are due to the presence of several climatic zones in the interior of the Iberian Peninsula, which explains why some areas of the North of Spain receive fewer hours of sunshine than even regions of Central Europe. The provinces of southern Andalusia and Canary Islands are which concentrated greater number of hours of sunshine per year, reaching the 2900 annual hs.
