There is a problem today that are the obstacles that governments put in many countries. Many increase prices by starting this activity and rates through the supporting tax.
All those who do not comply with the regulations of the government when installing solar panels can require substantial and exaggerated fines, so we will have to find out very well when installing our solar panel at home.
These measures are movements of the government with the large electric companies that do not want to start losing profits due to the possible installation of the panels since for anyone it would be an assured investment in the medium or long term. Therefore energy companies do their best to have many obstacles and users cannot install their panels.
