Solar panel roofing import Russia

Hello! I am looking for a roof with solar panels for a small house (30-35 m2). I don't need solar panels that are screwed to the roof, but panels that actually replace the roof.
I am looking for a roof with solar panels for a small house (30-35 m2).
I don't need solar panels that are screwed to the roof, but panels that actually replace the roof. The temperature range is from minus 30 degrees (snow) to about 30 degrees Celsius. The roof will be used in different weather conditions and must be durable.
I would like to find a company that can produce for us a complete set of elements for a solar roof (including an accumulator, inventory, etc.)
