The geothermal heat pump market is headed for another strong year in 2019. The 30% uncapped federal income tax credit on EnergyStar-rated geothermal heat pumps remains in full effect. Additional incentives are available from some state-level programs and electric utilities.
Interest in using solar photovoltaic systems to supply electrical energy to homes is also strong and looks to remain that way. In 2018, California become the first state to mandate use of solar PV systems in all new homes by 2020. Several state and federal incentive programs also generously support PV installations.
