Photovoltaic System Integration Where Feed-In Tariff Applied With Improving Return On Investment
High photovoltaic (PV) integration in electrical grid is one of the strategic goals for many countries nowadays. That's why many governments introduced incentive policies seeking for PV projects funded by private sector. These kinds of projects have to be a positive net present value (NPV) in order to get sponsorship by non-government sector. This paper investigates the PV solar system financial analysis in Malaysia and Turkey. In developing counties, the governments are looking for more renewable energy (RE) sources installation. Thus, they implemented Feed-in Tariff (FiT) mechanism to accelerate investment in renewable energy technologies. As the efficiency of the PV cell increases and the cost/Wp decreases with time, the expected net present value (NPV), return on investment (ROI) and payback period for the PV system are going to achieve a significant increase. The FiT rate in Malaysia is significantly higher than Turkey and the purchase agreement is longer. These advantages would make Malaysia a better place for PV system investment. Moreover, this paper proposed the PV system to be installed at the roof of building, merged with another suitable business such as; roller skating rink or cafe. This combination makes the PV project making income at day time via solar radiation, while generating income at evening and night time via the other business. The analysis results revealed that, the combination of PV system with roller skating rink or cafe can reduce the payback period and make a wonderful combination between green energy and people.
