Critical analysis of the current legislative framework for the disposal of photovoltaic modules and its economic evaluation
Zemková, Lenka ; Vojáček, Ondřej (advisor) ; Matula, Miloš (referee)
The Czech Republic has approximately 2 126 MWp of photovoltaic installed power capacity, most of the capacity was installed during the "solar boom" period around year 2010. Directive 2012/19/EU on waste electrical and electronic equipment led to the amendment of Act no. 185/2001 Coll. on Waste and the Decree no. 178/2013 Coll., which set the photovoltaic power plant operator´s obligation to pay a contribution for the module´s future recycling. The current rate for calculating the minimum total amount of the contribution is set at CZK 8.50/kg of module. The current amount of the contribution is a subject to criticism. The diploma thesis analyzes public administrations on issues of environmental protection and tools that may be used to motivate polluters. The thesis proposes a new amount of recycling contribution at the amount of CZK 5.2-7.8/kg. Huge temporal inconsistency is the most dangerous risk in determining the contribution, which may threaten many variables essential for the whole calculation.
Solar charge controllers for off-grid systems
KRČKA, Pavel
This diploma thesis deals with photovoltaic rechargable regulators used in isolated, or off-grid photovoltaic systems. First, basic types of off-grid installations, including their functions and applications in practice are described. Then, possibilities of electric energy accumulation in photovoltaic systems are mentioned, considering actual, accesible technologies. Matters of electric energy accumulation in leaden accumulators are examined in detail. Main part of the diploma thesis is about electronic designs of photovoltaic, also called solar, rechargable regulators. These are the main connecting part between photovoltaic panels, accumulator, but also often connected charge, which is appliance. Individual electronic regulators concepts are described narrowly, then compared and evaluated in thesis´ conclusion.
