چکیده
امروزه با توجه به افزایش غلظت گازهای گلخانه‌­ای و آلودگی­‌های زیست­­‌محیطی ناشی از سوخت‌­های فسیلی، توجه زیادی به استفاده از انرژی خورشیدی به عنوان انرژی پاک جهت تولید برق می­‌شود. اکثر سیستم‌­های خورشیدی استفاده شده در جهان به دو صورت فتوولتائیک اضافه شده در ساختمان BAPV[1] و فتوولتائیک ادغام شده در ساختمان BIPV[2] هستند. در پژوهش حاضر سیستم‌­های خورشیدی BAPV و BIPV و عملکرد آنها در سقف­‌های افقی و شیبدار در شهر ارومیه بررسی می­‌شود. برای این منظور، تأثیر سقف شیبدار در بازدهی پنل­‌ها و میزان انرژی تولیدی سالانه، با شبیه‌­سازی توسط نرم‌افزار PVsyst7.2 در زوایای مختلف مورد بررسی قرار می­‌گیرد. نتایج حاصل از زوایای مختلف در شبیه‌­سازی نشان می‌­دهد که سیستم پیشنهادی برای سقف شیبدار با زاویۀ­ 35 درجه بیشترین جذب انرژی از خورشید را دارد. با مقایسۀ بازدهی پنل‌­ها در سقف شیبدار با زاویۀ­ 35 درجه و سقف افقی مشخص گردید که با تعداد پنل یکسان، بازدهی پنل‌­ها در سقف شیبدار در سیستم BAPV، 16 درصد و در سیستم BIPV، 14 درصد نسبت به سقف افقی بیشتر است. همچنین میزان انرژی خورشیدی استفاده نشده در سقف‌های شیبدار با زاویۀ­­ 35 درجه با در نظر گرفتن الگوی مصرف در سیستم‌های BAPV و BIPV، 3.5 درصد کمتر از سقف‌­های افقی می­‌باشد. علاوه بر آن، با شیبدار کردن سقف با زاویۀ 35 درجه، فضای قابل دسترس در نمونۀ بررسی شده، 20 درصد افزایش می‌­یابد که می­توان از آن برای نصب پنل‌­های بیشتر استفاده کرد.

چکیده English

Today, due to the increase in greenhouse gas concentrations and environmental pollution caused by fossil fuels, there is a great emphasis on using solar energy as a clean source of electricity generation. Most solar systems used in the world are of two types: BAPV (Building Applied Photovoltaic) and BIPV (Building Integrated Photovoltaic). In this study, the BAPV and BIPV solar systems and their performance on horizontal and sloping roofs in Urmia city were investigated. For this purpose, the effect of the slope angle on the panel efficiency and annual energy production was examined at different angles using the PVsyst 7.2 simulation software. The simulation results showed that the proposed system for a sloping roof with a 35-degree angle had the highest solar energy absorption rate. Comparing the panel efficiency on a sloping roof with a 35-degree angle and a horizontal roof, it was found that with the same number of panels, the efficiency of panels on a sloping roof in the BAPV system was 16% higher and in the BIPV system was 14% higher than that of a horizontal roof. Moreover, the amount of unused solar energy on sloping roofs with a 35-degree angle is 3.5% lower than that of a horizontal roof, considering the consumption pattern in BAPV and BIPV systems. Additionally, by sloping the roof at a 35-degree angle, the accessible space in the examined sample increases by 20%, which can be used for installing more solar panels.
