The average cost of a square metre of photovoltaic solar panel is generally between 200 and 300 euros, excluding installation. Several factors influence the final price: the type of panel (monocrystalline, polycrystalline), its power, its size, and the quality of the cells. High-efficiency modules have climbed to €0. 115/Wp and are expected to rise further. How much do solar panels cost today? How much do solar panels cost in January 2026? How much do solar panels cost in. Thus, the cost per watt for that panel is $0. Global estimates are used before 2010; European market benchmarks thereafter due to limited data availability. Solar photovoltaic module prices refer to the cost of the solar panel itself, and do not include installation or other system. Here's what's shocking: A single square meter of solar panel can generate anywhere from 150 to 250 watts under ideal conditions. But "ideal" rarely exists in real life.
