It combines PV cells with<br \/>\n a thermal absorber so the system can deliver two outputs: electrical power and thermal energy.\n <\/p>\n<\/p><\/div>\n<h2 id=\"what-does-pvt-mean\">What Does PVT Mean?<\/h2>\n<p>PVT stands for <strong>photovoltaic thermal<\/strong>.<\/p>\n<ul>\n<li>Photovoltaic means the panel converts sunlight into electricity.<\/li>\n<li>Thermal means the panel collects heat that can be transferred to water, glycol, air, or another heat transfer medium.<\/li>\n<\/ul>\n<p>\n In standard PV modules, heat behind the solar cells is usually released to the environment. In a PVT panel,<br \/>\n part of this heat is captured and transferred to a useful thermal load.\n <\/p>\n<p>\n This does not mean PVT is automatically better than PV or solar thermal.

In a PVT panel,<br \/>\n part of this heat is captured and transferred to a useful thermal load.\n <\/p>\n<p>\n This does not mean PVT is automatically better than PV or solar thermal.
