Clean air, a pleasant climate and an increase in solar panel output of up to 15%.

Green roofs of apartment buildings with solar panels and shared energy between apartments. The dream of every inhabitant of a larger city, is becoming a reality.
Until now, people living in apartment buildings have had limited opportunities to use a common source of electricity, which is different from the situation in single-family homes. This was due to the absence of legislation that would allow sharing of electricity between households. However, the situation is changing for the better. The Council of the Energy Regulatory Office (ERO) has approved an amendment to the Decree on the Electricity Market Rules that will allow the sharing of jointly produced electricity in residential houses. This opens up the possibility of greater use of photovoltaics also for housing cooperatives or associations of owners of residential units.
The new decree allows for the sharing of electricity in apartment buildings by means of a leading point of consumption, which will be the only one for the whole building and will be connected to a common source of electricity. This point of consumption will be used to sell surplus electricity (overflow) from the house back to the grid. However, despite the creation of a lead point, there will still be associated points of consumption that will serve individual dwellings. This means that everyone will still be able to choose their own electricity supplier and consumer protection for them will remain unaffected.
This approach will make it possible to create a common source of electricity even if some apartment owners or co-op shareholders do not agree to its installation. This is because only those who express an interest in the project will participate.

When solar panels are placed on green roofs, the plants and the substrate underneath absorb heat, which lowers the temperature of the roof and allows the solar panels to work more efficiently. Projects that combine a green roof and solar panels are called BIOSOLAR roofs. Some research shows that a green roof can increase the performance of solar panels by up to 15%.
A green roof offers many benefits that contribute to improving the quality of life in an urban environment. One of the benefits is rainwater retention. A green roof can absorb rainwater with the help of plants, substrate and drainage layer. As a result, the load on drainage systems is reduced and less water runs off into canals.
Another benefit of a green roof is air purification. Plants and grass carpet filter particles from the air and convert carbon dioxide into oxygen. This feature helps reduce pollution and helps keep the air around the building cleaner.

Green roofs also reduce the ambient temperature. The plants on the roof absorb sunlight, while 50% of it is absorbed and 30% is reflected. This process helps create a cooler and more comfortable climate inside and out.
They can also reduce ambient noise. The grass carpet acts as a sound barrier and reduces noise from the outside environment, such as traffic noises. This improves the quality of life inside the building.
Extending the life of the roof is also an important benefit of a green roof. The grass carpet protects the roof material from external influences such as sun and rain, thus extending the life of the roof and increasing its resistance to external influences.
We hope you found the article useful and look forward to a green tomorrow.
