Publication Regional energy production with PV and CPV panels in north-west Turkey(Parlar Scientific Publications (P S P), 2020-01-01) Biçen, Tuğba; Vardar, Ali; Biçen, Tuğba; VARDAR, ALİ; Bursa Uludağ Üniversitesi; 0000-0001-6349-9687; CGD-9496-2022; AAH-5008-2021In this study, solar radiation data and current energy potential analysis were made in 12 locations selected in the north west of Turkey and solar energy characteristics of the region were revealed. In the research, especially the technologies used in the production of electricity from solar radiation were discussed. On the basis of regional characteristics of solar energy, the solar panels can produce different amounts of energy were determined. In this context, while the regional average of 166.3 to 223.3 kWh/m(2) of energy can be produced from monocrystalline panels (PV) and the regional average of 155.2 to 208,4 kWh/m(2) of energy can be produced from polycrystalline panels (PV) were determined. Additionally, the regional average of 310.4 to 416.9 kWh/m(2) of energy can be produced from concentrator solar panels (CPV) was established.Publication Technical and economic evaluation of energy production from wind in İstanbul and surrounds(Univ Cape Town, Energy Res Centre, 2015-11-01) Vardar, Ali; Taşkın, Onur; VARDAR, ALİ; TAŞKIN, ONUR; Uludağ Üniversitesi/Mühendislik Fakültesi/Biyosistem Mühendislik Bölümü; 0000-0001-6349-9687; 0000-0002-5741-8841; AAH-5018-2021; AAH-5008-2021Istanbul is located in the northwest part of Turkey and has the greatest population of any city in the country. Istanbul and its surroundings were researched for wind potential. Energy production from wind was evaluated technically and economically in this study. Corlu, Kumkoy and Sile sites were examined. Other sites in the same region (Goztepe, Kirecburnu, Bahcekoy, Florya and Kartal) were also evaluated but the results were not satisfactory, and for this reason, these sites were not examined in this study. When we checked daily, monthly and yearly wind speed values and frequency distributions, the wind energy potential of Corlu, Kumkoy and Sile were greater than other sites. Corlu, Kumkoy and especially Sile's wind speed data are statistically decreasing. A Nordex N117 91m hub height wind turbine can produce 6099 MWh in Corlu, 6459 MWh in Sile, 7265 MWh in Kumkoy. A Nordex N117 91m hub height wind turbine can produce 6471 MWh in Corlu, 7439 MWh in Sile and 8175 MWh in Kumkoy. The energy costs were calculated by the average of 36 years of wind measurement data using Nordex N117 turbines. Energy costs with Nordex N117 91 m and 140 m hub height in Corlu, Sile and Kumkoy are 0.025- 0,027 US$/ KWh, 0.022- 0,025 US$/ KWh, 0.020- 0,023 US$/ KWh, respectively.
