Use materials that do not scratch the panels, and if it is too risky, it would be advisable to contact experienced people in this field. Dirt prevents their maximum yield.
You can use the energy produced by the photovoltaic panels in real time. The export of surplus energy is not possible, being limited until the moment you become a prosumer.
By becoming a prosumer, the surplus electric power produced by the photovoltaic panels is exported to the national grid to which you are connected. You can use that exported-to-the-network surplus energy at night, on cloudy/rainy days and during winter when the panels no longer produce as much energy as in summer.
