Cost-Benefit Analysis with Dashboard of Solar Panels for Residential Malaysia

This study develops an investigation of the economic and practical feasibility of the installation of residential solar panels in Malaysia, with a developed web-based dashboard that could be of help for decision analysis. Given the abundant solar irradiance in Malaysia and its supportive energy policies, the research integrates local consumption data, government incentives, and the cost structure into a cost-benefit analysis framework. This study has presented a dashboard that calculates estimates of energy usage, optimal system sizes, and financial metrics like payback period and ROI, computed with respect to user-specified inputs. The result shows the payback period for the solar installations in the range of 5–7 years, whereas the return on investment is around 55% within a span of ten years. The dashboard bridges the gap between technical feasibility and actionable insight, thereby enabling the homeowners to make an informed choice while standing at par with Malaysia's sustainability and renewable energy goals.
