What is the output of a Solar Thermal panel in terms of kWh?
This varies according to the time of year. In the summer months we get approximately 10 times more solar energy than in the winter months. In the summer, you can expect to obtain an average of 14kWh of heat per day from a single 20 tube panel, compared with in December when you can only expect an average of 1.15kWh per day. Depending on the number of panels installed, during the winter months on clear sunny days, it is possible to heat your water to 40C and more.
