A three new roof-mounted 10 kWp grid-connected photovoltaic (PV) power plants have been constructed in the Technology Park at the Technical University of Gabrovo, Bulgaria, as part of a project “Competence Center – Intelligent Mechatronic, Eco and Energy Saving Systems and Technologies”. Three different types of technology of the PV modules have been used: monocrystalline silicon (mono-Si), cadmium telluride (CdTe) and copper indium gallium selenide (CIGS). With the new three power plants, together with the existing photovoltaic power plants in TU-Gabrovo with modules of amorphous silicon and poly-crystalline silicon, 5 different photovoltaic materials can be tested simultaneously. A small 500 Wp mono-Si photovoltaic thermal hybrid solar collectors (PVT) PV system is also constructed. The power plants are equipped with a system for monitoring the meteorological and electrical operating parameters, which measures, displays and stores data on solar radiation, temperature, wind speed, currents, voltages, and electrical power of each power plant. The technical characteristics of the components of the PV plants are given in the paper. Schemes with a basic wiring diagram, disposition of the three PV subsystems on the roof of the building at the technology center are presented. Initial comparative data from software for monitoring of meteorological and electrical operating characteristics of the three different types of PV subsystems are shown. Data on the saved CO2 emissions from the avoided production and transmission of electricity according to the specific ecological equivalent of energy resources and energy for the region of Bulgaria, due to the operation of photovoltaic power plants, are presented.
