Research On Design And Simulation Of Photovoltaic Systems In Area Of Building Energy Efficiency

Energy and environmental issues becoming an increasingly prominentissue restricting the sustainable development of China’s economy and society.With China’s rapid economic development, windling non-renewable energyresources and environmental pollution is worsening, making renewable energydevelopment and utilization becomes particularly important. Unlimitedresources through solar cells, clean solar radiation is converted to electricitysolar photovoltaic technology, new energy and renewable energy animportant member of the family. How rational and efficient use of solarenergy through photovoltaic technology has important implications forbuilding energy efficiency.This article based on the typical villa in locality as an example, accordingto regional characteristics of the region, to design a set of complete gridphotovoltaic power generation systems. completed the selection of theconfiguration of equipment, serial-parallel design capacity design, andnetwork components and electrical design for each design aspects have beenanalyzed in detail and calculations, ensure that the design is reasonable.Through professional PV-aided design software PVsyst, the budget of thisset of photovoltaic power generation systems, economic and environmentalbenefits for25years, the budget for the cost of inputs. Meanwhile, there areunavoidable for obstruction caused by occlusion of the PV system when thissituation modeling and simulation analysis, through in-depth analysis of theperformance of the components, the impact of power generation arrangementcomparing PV array. This conclusion has guiding significance for the properperformance of power generation photovoltaic arrays arranged in a particularshade can play better components. Number of PV modules and batteriesseveral independent systems using traditional formulas calculated using LOLPalgorithm optimized design to meet user needs in the premise, after a reasonable number of PV design reduces the number of components and theconfiguration of the battery, reducing the cost to avoid the waste of resources.Studied the life cycle cost analysis used in photovoltaic power generationsystem to verify the feasibility of the grid system solutions.
