Fontis sol

The production of solar systems is the fastest-growing industry in the world today, achieving an annual growth rate of 30% in recent years. This fact has been a driving force since the company’s inception, dedicated to implementing systems based on renewable energy sources for generating electrical and thermal energy. Importing complete elements of solar systems proved insufficient, prompting an exploration of their production possibilities in Montenegro. Fontis Sol has achieved notable results in this regard.
Montenegro has a long tradition of bauxite processing and aluminum production, with industrial capacities and a skilled workforce established over 50 years. For manufacturing solar cells, both monocrystalline and polycrystalline, silicon is used. According to existing research on non-metallic mineral resources in Montenegro, the country has around 10.5 million tons of silicon-bearing materials with silicon content ranging from 45% to 89%.
Solar cells are integrated into modules, which are assembled into panels with capacities ranging from 1W to 300W depending on consumer needs. Aluminum, extensively processed in Montenegro, is used for solar panel frames, adding another advantage for producing these systems locally.

With excellent climatic conditions, including 1,200 to 2,800 annual sunshine hours, Montenegro is naturally predisposed to utilize solar energy. Each square meter of flat surface receives solar energy annually equivalent to 200 cubic meters of natural gas, most of which remains untapped. Adding geothermal energy, groundwater, wind, and air, it becomes clear which direction economic resource development should take.
Montenegro’s terrain configuration—southern slopes of mountains and hills facing the Sun—makes it ideal for installing solar plants, often on otherwise unusable land. Solar panels come with a 25-year warranty, unmatched by any other product. They offer consistent, reliable, stable, long-term, and efficient energy production without requiring additional fuel. With a lifespan of 30 to 50 years, maintenance and servicing costs are minimal. Solar panels can be installed and used for energy production at virtually any location worldwide.
Wind generators are also used for electricity production, though their application is limited to areas where wind conditions ensure economic viability. The economic rationale for renewable energy sources overwhelmingly favors solar panels: the installation cost for 1 MW of capacity from solar panels is approximately €600,000, compared to €2 million for wind generators and €2.5–3.5 million for small hydropower plants.
Social valorization of optimal energy sources is crucial, given the growing energy demands. However, this need should be met with locally generated energy, minimizing transmission losses, and ensuring stability and long-term sustainability. Renewable energy sources have minimal environmental impact, are constantly technologically advancing, and are becoming increasingly efficient, with shorter investment return periods for investors.

Using renewable energy is a fundamental prerequisite for the sustainable development of any community. For thermal energy production, Fontis Sol develops projects based on solar collectors and heat pumps. Solar collectors use a heat exchanger to heat water in a boiler, which is then distributed to taps. This system is free to operate, as it uses solar heat to warm water. Solar collectors can provide sufficient hot water from February to November in Montenegro’s coastal areas, from March to October in the central region, and from May to September in the north. They are easy to install and compatible with existing installations.
Heat pumps, in addition to heating water and spaces, can also cool spaces. They utilize groundwater, geothermal energy, and air as free energy sources. However, they require electricity for operation. For every kilowatt of energy consumed, heat pumps produce four kilowatts of thermal energy. They operate independently of weather conditions and seasons but require specific building conditions for optimal use, such as good insulation. Other system components depend on the project and investor requirements.
