For the construction of a solar PV power plant on a dilapidated house, you will most likely receive a grid connection refusal. Although it appears on the municipal plans, you need to bear in mind that a person from EVN does a site inspection and takes pictures of the property and buildings. That is, if the house is visibly dillapidated, it will not be recognized as a building. If you restore it so that it is intact, in our opinion, you will not have any problems.
