This paper presents the techno-economic feasibility analysis of an on-grid Photovoltaic Solar System (PVSS) subject to Mediterranean climate aging effects. The PVSS under study is considered installed on the roof of Shymkent airport, located in southern Kazakhstan. A PVSS performance degradation rate of 1.48%-per-annun was considered according to the Mediterranean climate prevailing in the location. A 25-year life-cycle cost analysis comparing the rated vs. de-rated on-grid PVSS led to a positive Net Present Value (NPV), a less than 9-year equity payback, and favorable internal rate of return (IRR) and Benefit-to-Cost (B-C) ratio in both conditions. However, the de-rated PVSS system underperformed in 16.2%, 43.5% and 20% the IRR, NPV and B-C ratio, respectively. The analysis demonstrates that despite the expected performance degradation associated to climatic aging, a convenient feed-in tariff (FIT) and attractive financial conditions, such as those present in Kazakhstan, conform a robust setting to promote on-grid PVSS in the country.

Abstract This paper presents the techno-economic feasibility analysis of an on-grid Photovoltaic Solar System (PVSS) subject to Mediterranean climate aging effects. The PVSS under study is considered installed on the roof of Shymkent airport, located in southern Kazakhstan. A PVSS performance degradation rate of 1.48%-per-annun was considered according to the Mediterranean climate prevailing in the location. A 25-year life-cycle cost analysis comparing the rated vs de-rated on-grid PVSS led to a positive Net Present Value (NPV), a less than 9-year equity payback, and favorable internal rate of return (IRR) and Benefit to Cost Ratio (BCR) in both conditions. The analysis demonstrates that despite the expected performance degradation associated to climatic aging, a convenient feed-in tariff (FIT) and attractive financial conditions, such as those present in Kazakhstan, conform a robust setting to promote on-grid PVSS in the country.

Kata kunci: Analisis kos kitaran hayat, jambatan konkrit, pengaratan, langkah, pembaikan, pemulihan struktur, keberkesanan kos, kaedah nilai bersih kini (NPV) This paper discusses a short study on life cycle cost analysis (LCCA) on corrosion remedial measures for concrete bridges and marine structures, which are subjected to carbonation or ingress of sodium chloride from sea water and other sources. Life cycle costing software, Bridge LCC 2.0, was used to perform life cycle cost analyses on three case studies, based on net present value method. The analysis of the results showed that LCCA is capable of assisting engineers or transportation agencies to evaluate optimum maintenance decisions in corrosion–related problems. It can be used as an engineering economic analysis tool that helps in qualifying the differential costs and choosing the most cost–effective corrosion remedial measures. Life cycle costs for the remedial measures are influenced by many costing variables such as initial costs, periodic maintenance costs, frequency years and analysis period. The best practice of LCCA should not only consider agency expenditures but also user costs and sensitivity analysis throughout the service life of a remedial measure. Key words: Life cycle analysis, concrete bridges, corrosion, remedial measures, structural rehabilitation, cost-effective, net present value method (NPV)

In India, dairy farming is traditionally practiced enterprise as a supplementary income source with the crop production. The present study was undertaken to analyze the Economic feasibility of Self-Help Groups (SHGs) microfinance for dairy enterprise run by women particularly from buffalos in Marathwada region of Maharashtra state. Whole study was based on the primary data set which was collected from the Parbhani district for year 2015-16. Multistage sampling design was used in selection of district, tehsils, villages and SHG groups. The cross sectional data was randomly collected from the 70 members of buffalo rearing selected SHGs. So the required data was collected by personal interview method using pre tested schedules. The data collected was subjected to tabular and economic feasibility analysis i.e., Net Present Value (NPV), Benefit-Cost Ratio (B/C ratio), Internal Rate of Return (IRR) and Net benefit – investment ratio (N/K ratio). The study revealed that the net present value was found positive and benefit cost ratio more than unity. The internal rate of return was higher than bank rate. So in the study area dairy is feasible enterprise and very much suitable for rural women to practice and empower them economically and socially. This feasibility analysis showed that dairy enterprise through microfinance gives more returns to women entrepreneurs. So, the financial institutions and NGOs should come forward to extent economic support and guidance to rural women through SHGs to take up these enterprises as an income generating activity.
