Solar District Heating

Greening rural and urban heating grids
Solar District Heating feeds heat from solar thermal collectors into existing or new district heating grids. Solar district heating solutions were already implemented from small villages up to cities with several hundred thousand inhabitants. Innovative concepts of SOLID include storage and load management, yielding the highest solar fraction and lowest energy rate.

Shutting off the boiler in summer months

With a large scale solar thermal plant and heat storage like in Mürzzuschlag, there is no need for low load summer time operation of large boilers

Solar district heating is the major opportunity to increase the overall renewable heat supply and energy efficiency in urban and rural areas. It reduces carbon emissions and air pollution.

„Traditional“ Solar District Heating works with diurnal heat storages and delivers heat mainly in summer months and shoulder seasons.

Innovative BigSolar solutions from SOLID work with seasonal storages and deliver heat to the grid and the customers all year round, see here.
