https://jt.org/easy-tips-on-choosing...-solar-system/ says heating a home from solar panels can be done in two ways:
By the method of direct (water, antifreeze) in the heating system. This is done by concentrating the sun's rays on storage tanks, or tubular circuits along which water moves.
Using solar panels that generate electricity. In this case, the work of solar panels for heating housing is similar to the action of electricity from the general grid.
Panels with photocells operate when heating water in the heating circuit according to the following principle - sets of solar panels, converting the energy of the sun's rays into electricity, charge the batteries. From them, the current enters the inverters, which convert it in voltage, frequency, strength. From there, electricity is supplied directly to heating devices, such as an electric boiler.
