Environmental LicensingEnvironmental licenses can take a long time in a bureaucratic process, if not properly prepared its can be easily denied by State organs.
The choice of a technology for an enterprise must take into account not only its initial investment, but also its secondary gains and long term costs. Remember that the technology adopted in the project will remain for more than 20 years.CrystallineTrackerCrystallinemodulesingeneral provide greaterefficiency and lower Wp-cost.Howeverthistechnologyhasmajorlossesduetowarmerlocaltemperatures,itschoicemustbeevaluated.Thin FilmThinFilmmodulesingeneralprovidelowerefficiencyandtakeupmorearea,raisingthecostswithstructurewiringsystemandworkforce.

Operation and maintenance is crucial to the profitability of the enterprise. Its improper sizing can create risks to assets or jeopardize the power plant productivity.It is essential to evaluate the availability of water resource at the power plant location. An PVPlant uses a significant amount of water for cleaning the modules, specially in dry areas wherethe resource is scarce.The PV plant are usually located in remote places and have fragile and vulnerable equipmentwhich may be vandalized. An adequate monitoring and security are important and can increasethe operation and maintenance costs significantly.Production loss by dirt/dust can be significant, especially in arid regions. An efficient plan for cleaning the modules is important.Technical CharacteristicsOperation and Maintenance
CAPEX CompositionUnderstanding the impact of each driver:Local ModulesImported ModulesCost StructureLocal produced modules are an option for the current and future entrepreneurs in the sector. As the costs are 35% to 45% higher than the imported modules, the PV projects using local modules requires favorable financing conditions provided by development banks.Used by most Utility Scale Projects, imported modules feature substantially lower costs than the local modules, however they limit or prevent access to resources of development banks.
As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
