This solar module is composed of monocrystalline cells; therefore, it contains pure crystalline silicon. If you only have a relatively small south-facing roof area available, then solar power production with monocrystalline modules is the ideal solution: of the various types of photovoltaic modules available, the monocrystalline ones are the most effective, both in direct sunlight and in low light. Thus, you get the maximum electricity from a small footprint and cover all your consumption - even if it should be relatively high - with environmentally friendly self-production.
