Description
Summary:PV panels price decrease with average efficiency growth is a stable trend for modern solar energy technologies. In these conditions several companies proposed control systems for solar water heating, substituting solar collectors by PV panels. Advantages and disadvantages for such scheme application in Russian conditions are discussed in this paper. Results of PV water heater experimental testing in Moscow climate conditions and numerical simulation of collector versus PV panels in several Russian region are also given, as the development of earlier economic estimations. Both maximum power point tracking (MPPT) PV array control scheme and array with constant load discharge have been tested. MPPT revealed better efficiency, but special controller without battery application is needed.
