چکیده

ایران یکی از کشورهای با پتانسیل بالای استفاده از انرژی خورشید است و بیش از 300 روز هوای آفتابی در سال دارد. در این تحقیق، امکان احداث نیروگاه خورشیدی در چند ایستگاه تحقیقات کشاورزی منتخب در استان‌های مرکزی، اصفهان و کرمان از لحاظ فنی، محیط زیستی و اقتصادی مورد بررسی قرار گرفتند. در این راستا، بعد از تعیین اطلاعات هواشناسی مورد نیاز با استفاده از نرم‌افزارMeteonorm  و شبیه‌سازی سامانه توسط نرم افزار PVsys، به تحلیل اقتصادی و تعیین نقطه سر به سر و میانگین قیمت تمام شده تولید انرژی برای نرخ‌های تنزیل مختلف پرداخته شد. همچنین کاهش آلایندگی در اثر کاهش انتشار گازهای  Cox، Nox و Sox با توسعه نیروگاه خورشیدی بررسی شد. طبق نتایج، حداکثر میزان تولید برق در سال در ایستگاه‌ رودشت اصفهان معادل 303 کیلووات ساعت بر مترمربع می‌باشد. احداث این نیروگاه‌ها از تولید 748 تن آلاینده حاصل از احتراق سوخت‌های فسیلی برای تولید برق جلوگیری می‌نماید. همچنین مشخص شد که با لحاظ تعرفه خرید انرژی الکتریکی (6370 ریال بر کیلووات ساعت)، احداث نیروگاه‌های فتوولتائیک با نرخ معمول تسهیلات اعتباری که بیش از 8 درصد است، از توجیه اقتصادی لازم برای سرمایه‌گذاران برخوردار نیست لذا با عنایت به اینکه اجرای این پروژه‌ها باعث تولید انرژی‌های پاک می گردد و اثرات مثبت زیست محیطی به همراه دارد، به همین منظور توصیه می‌شود تسهیلات ویژه بانکی با نرخ بهره کمتر از 8 درصد برای توسعه آن در کشور در نظر گرفته شود تا انگیزه ورود بخش خصوصی به این عرصه بر قرار گردد.

چکیده [English]

Iran has a high potential of solar radiation and lots of sunny days (more than 300 days) in a year.  In this study the feasibility of establishment the photovoltaic powerhouse in several agricultural research stations of Markazi, Esfahan and Kerman Provinces was investigated. In this regard, after determining and analyzing the required meteorological information using Meteonorm software and system simulation by PVsys software, economic analysis of each station were performed by determining the breakeven point and the average cost of energy production for different discount rates. The study also examined the reduction of pollution due to the reduction of Cox, Nox and Sox emissions as a result of employing photovoltaic power plants. According to the results, the most solar electricity generation was occurred in Rudasht station of Esfahan province equaled to 303 kWh/m2 per a year. Photovoltaic powerhouse establishment in the research stations could eliminate pollution production up to 748 tons in a year which exhausted from fuel combustion in the power generation turbines. Results also illustrates considering electricity purchase tariff (6370 IRR/kWh), the construction of photovoltaic power plants with the usual interest rate (more than 8%) is not economically viable for investors. Therefore, the implementation of such projects cusses to produce clean energy and to bring environmental protection, a special banking facilities with interest rates below 8% is recommend to motivate private sector for investment.
