Due to the significant differences in solar irradiation within the European Union more roofs in southern Europe are suitable for solar installations than in northern areas.
The EU Solar Rooftop Standard applies to new non-residential and public buildings from 2027, to existing non-residential buildings undergoing major renovations by 2028, to new residential buildings from 2030 and on all suitable existing public buildings by 2031.
Total rooftop solar capacity in Europe stood at more than 170 GW at the end of 2023 and is expected to grow to 355 GW by the end of 2027. In addition to the obligatory solar installations under the Solar Standard, the growth of rooftop solar on homes is also likely to increase, as citizens seek to shield themselves from fossil price volatility.
According to our calculations, the average-sized roof can produce about 21,840 kilowatt-hours (kWh) of solar electricity annually—about double the average U.
The rooftop solar panels are space-saving, cost-efficient aids that increase the roof's strength and reduce your electricity bill by ensuring abundant energy. Let's discover eight steps for installing solar panels on the roof, helping you reap optimal benefits from installing solar rooftop panels.
The physical attributes of your roof play a crucial role in determining the capacity of your solar power system. Your roof area determines how many solar panels you can install, with more resulting in higher energy generation potential. Additionally, the orientation of your roof to the sun also affects the efficiency of your solar panels.
The amount of solar power your roof can generate depends on various factors, such as your location, roof size and orientation, solar panel efficiency, shading, climate, and the size of the solar system. But our experts can help you find a solution to meet your energy needs.
Photovoltaic panels require direct sunlight to generate energy, so while installing solar panels on the roof it makes sense to remove any shade that may reduce or interfere with sunlight. The majority of the time, the shade comes from neighboring trees or tall structures.
Ideally, your solar panels will be installed on a south-facing roof at an angle of about 30°. These are the optimal conditions for solar panel production. The closer you get to this, the more electricity your panels produce. Solar panels with a larger power-to-size ratio will produce more electricity per square foot.
Additionally, the orientation of your roof to the sun also affects the efficiency of your solar panels. A south-facing roof in the Northern Hemisphere is optimal for solar energy production. Panels facing the sun directly can capture more sunlight throughout the day, maximizing electricity generation.
