Economic assessment of some solar installations developed at the Politehnica University of Timisoara, Romania

We present an economic assessment of three solar thermal applications developed at the “Politehnica” University of Timişoara, Romania. The technical and solar radiation data have been obtained by measurements performed in the solar energy laboratories of the university. The economic effectiveness of the solar systems is assessed in terms of the present worth of the cash flow calculated for the life time of the installations. The presented results and underlying calculation procedures are useful for small developers of solar energy applications in view of home use.
