Latvian climate conditions have a potential for solar usage, but there are many reasons why consumers have skepticism and a perception that the climate conditions in this region is not suitable for solar energy usage. To avoid this stereotype, this study is conducted. The aim of this study is to explore the suitability of Latvian climate conditions with the use of solar collectors. There are many countries which are located in sunny regions and which history of solar energy usage is very longstanding, wherewith also technological achievements are high, yet our contemporary rapid technology development enables to use ever more solar energy in the regions which are not so rich with the solar radiance, for example Latvia. Interest about the usage of solar energy in Latvia increase – partly it is explicable to unpredictable and essential price rise of fossil fuel and partly to the desire to invest in technologies which could reduce this rise in price in the future.
