The main objective of this paper is to try to find solutions to the main problems that hinder the development of the Croatian market of solar energy. Trade, through its function of informing the consumers is the solution to the biggest obstacle to having better business results, which is poor knowledge of most citizens about solar energy. The paper shows the importance of trade, its role in the economy and presents the functions of trade with special emphasis on the proces of transfering information about products to the consumers. The Croatian market of solar equipment is analyzed in detail by showing the types of companies that exist in the market (manufacturing companies, specialized companies that trade solar equipment only, companies that alongside solar equipment sale other products), by showing the main suppliers, product prices, and the most important elements of the offer. The emphasis is on the market leader and on the proposal of a small solar power plant called "key in hand", as an important contribution to the Croatian market, which significantly facilitates and simplifies the investment in solar energy for the customers. This paper shows the complex procedure an investor has to go through to get all the licences required to use solar equipment , and the options that are available to him in that proces. The foundations of renewable energy sources which are usable in the Republic of Croatia are given, with special emphasis on solar energy. The overall situation of solar energy production in the European Union is also covered, with emphasis on the directives given by the European Comission about the future of renewable energy resources. Marketing is the most powerful tool for disseminating information to the consumers, but when it comes to solar equipment, companies should focus on one-to-one marketing, presentations and customer relationship management. Education on renewable energy sources will deepen public interest in the environment and develop a love for nature. An empirical research examines the awareness of Croatian citizens about solar energy and the current state of the market of solar equipment. At the end, possible solutions are given to the problems that are inhibiting the Crotian market of solar energy.
