Vybudování a provoz fotovoltaické elektrárny / Installation and operation of photovoltaic power plantMERTLÍKOVÁ, Petra January 2012 (has links)
In my dissertation I describe the photovoltaic power plant on the roof a family house, the conditions of connection to the electricity network, the electricity consumption and I state in detail the technical specifications of this solution. Moreover, I give details of price quotation plus estimated quantity of produced electric power. Besides, I pay attention to the investment efficiency. Main part of the dissertation is devoted to the analysis of produced electric power for the period from 1.1.2010 till 31.12.2010 for each quater of the year seperately. The above mentioned study implies that the photovoltaic power plant meets in so far all requirements and the investment should be returned in approximately 9 years. The aim of the dissertation is to judge the photovoltaic power plant with respect to its installation, operation and return on investment.

Efektivnost provozu fotovoltaických generátorů / Operational efficiency of photovoltaic generatorsKoval, Filip January 2008 (has links)
Objective of master’s thesis theoretical part is especially to illustrate influence of operation conditions, such as solar radiation, temperature or pollution of photovoltaic generator active area, on load and power characteristics of photovoltaic generator, or more precisely on photovoltaic conversion efficiency. Possible variants of increasing effectivity of using photovoltaic generator are explored, such as solar radiation concentration, photovoltaic generator active area cooling or aplication of optimalization circuit. Pivotal part of master‘s thesis is focused on experimental device practical realisation, concretely type MSQ36-10 photovoltaic generator with oriented concentrators of solar radiation. Practical realisation includes design of master‘s thesis experimental part construction with subsequent design of photovoltaic generator motion cycle necessary for adequate simulation of configuration variants solved using single testing photovoltaic generator. Description of own experimental device construction with list of measuring places used in task takes up. It is used automatic monitoring system working as independent measurement task for required values measuring and consecutive data collecting. It is done in two phases. First phase is measurement of all required values, in second phase measurement with attached optimalization circuit is made. Optimalization circuit sets best working point of photovoltaic generator according to actual working conditions. Master‘s thesis intention is experimental verification of solar radiation concentrators application convenience, orientation of photovoltaic generator or its mutual combination, namely using type MSQ36-10 photovoltaic generator. Objective is evaluation of reached energetic gain for all experimental device layouts in variable operating conditions.
