What they do
Solar photovoltaic system directly converts solar energy into an electrical current. Photovoltaic panels absorb sunlight and convert it into an electric charge. This electric charge can be used to power your home appliances.
Solar thermal energy makes use of the sunlight to produce heat. Heat acquired by the solar thermal energy process can be used for water heating and radiant space heating.
Solar thermal or solar heat technology is highly efficient as compared to the solar electric power. Storage of heat is much easier and cost-effective than the storage of electricity produced by PV panels. Solar hot water system is more than eighty percent efficient where solar panels are only fourteen to twenty percent efficient. It makes the solar hot water system most efficient and advanced technology of solar energy.
Collection panels are the basic equipment used in both solar electric system and solar thermal system. Collection panels gather energy from the sun and convert it into electricity or heat. Basic unit of solar electric system is photovoltaic cells, an array of PV cells make photovoltaic panels used to produce electricity. Solar heat panels are linked with plumbing, and photovoltaic panels are connected with wiring - which is another difference between the two systems.
Solar thermal equipment can not only produce electricity for your home, but it also solves your hot water and other heating problems. Solar hot water system allows you to have highly efficient source of heat and hot water for your shower, laundry and dishwashing.
