Abstract

Due to the
polluting effect of fossil fuels on environment and their exhaustible nature,
investments in renewable energy resources continue to increase. In order to
benefit from solar energy which is one of these energy resources, 50 GW of new power
plants were installed only in 2015. Following the "regulation on unlicensed
electricity generation" issued to benefit from the renewable energy
potential available in Turkey, the installation of systems that generate
electricity from solar energy via photovoltaic power is rapidly increasing. The
use of simulation software is very important in the design and analysis of
photovoltaic solar power plants. In this way, it is possible to obtain production
data and conduct investment analyses before the power plant is established. Some
of the simulation programs are web-based. In this study, web-based solar energy
simulation programs PVGIS and Sunny Design Web were investigated and the proximity
of simulation results to the actual results was studied. Dicle University Solar
Power Plant was selected as the study field in order to compare the simulation
results of the software. Dicle University Solar Power Plant is a photovoltaic
solar power plant established and operated within the Engineering Faculty of
Dicle University for introduction, education, production and analysis purposes.
In the study, simulation of the 250 kWp solar power plant established in Dicle
University was performed with PVGIS and Sunny Design Web software by using
installation parameters and thus, one-year production values were obtained. The
results of both web-based programs are compared with each other and with the
actual production values from the plant.
