As concerns solar energy, it could be used for production of thermal energy (by solar collectors) and electric energy (by solar PV batteries). The sunlight duration and intensity depends on the season, weather conditions and geographical position of a country. In the northern Europe the maximum value of solar radiation is 1100 kWst/m2. As shown by experimental studies in Institute of Physical Energetics (IPE), the application of solar collectors in Latvia can give good results. The energy of solar radiation can be employed for 1700-1900 hours annually. The reasons that make the use of solar energy attractive and suitable in Latvian conditions in the last years are as follows:  High consumption of hot water in summer time (typically taking place in dwelling houses and such public institutions as hospitals, hotels & camps, sportive and summer camps).  Tendency for energy price increasing.  Construction of new buildings in which solar collectors and PV could be built-in. Latvian’s energy policy now provides use of RES, accordingly to the “Law of Energy Efficiency in Building” article 7 recommends use of RES in the new buildings and renovated buildings.  Significant advantages for solar energy use for electricity production appeared in this year. The new Regulations “Rules for the generation of electricity from renewable energy resources, and pricing arrangements” was adopted in February 2009. Due to these Regulations transmission grid operator is obliged to pay the feed-in tariff for electricity producers which use solar energy for electricity production (PV) (purchase price of solar power is 427 EUR/MWh).
