you can put solar panels on the floor. Usualy solar panels needs to be on a not cold place, then climat cant be cold other wise it won't work because the sun is the font of energy of the solar energy.
you can also put in the sealing and that is a good idea because some times put in the sealing the solar panel get high. Some times when you put it high it makes easer to tranform the sunlight into energy in the house.
The sun is the font of energy then the sunlight goes to the panels and the panels take the sunlight to some turbines and this turbines turn into energy
