Solar Panels Can Be Used to Provide Heating and Air Conditioning (image) Carlos III University of Madrid Share Print E-Mail Caption The use of solar panels to produce toilets hot water is standard practice, but researchers at the Madrid Universities Carlos III and Politécnica suggest that they may also be used to provide large offices with heating in the winter and air conditioning in the summer. Their proposal involves the incorporation of solar collectors into a gas-based cogeneration system with an absorption machine, which would reduce both energy expenditure and CO2 emissions.
