研究目的
To evaluate the performance of a photovoltaic (PV) system installed on the roof or integrated to the south-facing fa?ade of residential apartments in Padiham (53.5 N, 2.3 E), UK, and to compare the energy and economic performance of the most common PV module types.
研究成果
The study concludes that monocrystalline modules have the best energy performance, while thin-film modules have the best economic performance under the considered conditions in the UK. The decision-maker's preference should be considered when choosing the PV type and brand due to the trade-off between energy and economic performance.
研究不足
The study is limited to the meteorological and working conditions of Padiham, UK, and considers only the brands mentioned in the report by the Fraunhofer Institute for Solar Energy Systems, ISE. The economic analysis is based on assumptions and data collected from literature, which may not reflect current market conditions.
1：Experimental Design and Method Selection:
The study involved building a computational model to estimate the available solar energy with a resolution of 1 hour per square meter of surface considering different slopes and azimuth angles. The model was used to determine the optimal azimuth and slope angles of the PV modules for maximum annual electricity generation.
2：Sample Selection and Data Sources:
The study considered different brands of PV modules (monocrystalline, polycrystalline, and thin-film) based on a report by the Fraunhofer Institute for Solar Energy Systems, ISE. The specifications of the PV modules were collected from technical brochures provided by the manufacturers.
3：List of Experimental Equipment and Materials:
The study utilized PV modules from various brands, an inverter for grid-connected systems, and assumed a total PV plant area of 100 square meters.
4：Experimental Procedures and Operational Workflow:
The simulations were carried out for modules installed on the roof and on the south-facing fa?ade of a residential building under the meteorological conditions of Padiham, UK. The model simulated hour-by-hour energy and economic performance.
5：Data Analysis Methods:
The performance of the PV modules was evaluated based on annual electrical energy generation and economic figures of merit such as investment, annual profit, net present value, levelized cost of electricity, and payback time.
