The first part of the course discusses thermoelectric energy conversion and thermoelectric materials, thermionic energy conversion, and photovoltaics. The process of converting energy from the sun into electricity is called solar energy or solar power, which even our ancestors used for their benefit, namely to produce fire. HTST power plants are a lot like traditional fossil fuel power plants, but the important difference is that they obtain their energy input from the sun, instead of from fossil fuels. Würfel, Peter, and Wolfgang Ruppel. The system is also generating around 55 kWh of thermal energy daily, and annual thermal energy production is estimated at approximately 16,000 kWh. This system is composed of a turbine, condenser, evaporator, pump and flat plate solar collector.
