“…Besides reducing leakage, retrofit mounting is becoming an increasingly popular option (Union of Concerned Scientists, 2015). Rooftop 𝐵𝐼𝑃𝑉 installations are an excellent method of obtaining clean energy (Lee et al, 2019) but they also have their own set of factors that can reduce their power output (Pandey et al, 2022). There are some studies on the relationship between the immediately built environments such as roof type material and a gap between the 𝑃𝑉 modules and the roofs on the operating 𝑇 𝑐𝑒𝑙𝑙 .…”

“…Yusoff et al (Yusoff et al, 2017) found that the 𝑇 𝑐𝑒𝑙𝑙 and the temperature difference (𝛥𝑇) are dependent on the roofing material type, 𝑃𝑉 technologies, irradiance and the gap height in between the 𝑃𝑉 module and roof surface. The amount of energy generated by these rooftop solar arrays depends on a variety of factors, including the weather, the design, and the arrangement and alignment of the PV modules (Pandey et al, 2022). The performance of 𝑃𝑉 modules degrades significantly as their operating temperature rises (Haidar et al, 2018).…”

This study presents an innovative air-cooling photovoltaic (PV)system using cross-flow fan with speed regulation to optimize performance of rooftop PVsystem in tropical climates like Malaysia. Air passed through the impeller enters perpendicularly to the motor shaft, deflected by the fan blades and evacuated, allowing the fan to operate at its most efficient operating point. The airflow provided within the rear of the PV modules and the roof surface blow out the trapped hot air. Changes in the module temperature (Tcell) are detected and the fan speed are adjusted accordingly to the PWM. This method was tested for 12 hours continuously from 7:00 am on the existing PV system at German Malaysian Institute (GMI) Bangi. The highest Tcell achieved 72.88 °C and 55.75°C without and with air-cooling system with average power 210.22 W and 246.67 W per peak sun factor (PSF) respectively. There was a 17.34% increase in average power with a 13.18% in average net output power and achieved 6.68% energy efficiency using the proposed cooling system. Tcell increases more swiftly and reaches higher temperatures in the absence of a cooling system, whereas Tcell increases more slowly and at lower temperatures when a cooling system is present. The projected system's power rating was 6.48 W, which is 2.6% per PV module, and it really attained 6.32 W, which is 2.53% per PV module, while total energy consumption by the fan was 51.89 Wh per day, which is only 3.89% per PV module.

“…Placement of rooftop solar PV with a higher roof slope reduces the level of shadow loss because it reduces the slope of the panels with respect to the roof surface and the roof surface area increases, resulting in more solar panels installed and an increase in the output power of the array [33]. Meanwhile, building boundary features can have a significant impact on the application of rooftop solar PV technology [34].…”

The use of solar PV as an alternative to fulfill household-scale electricity needs has begun to be widely developed. However, the problem of investment costs and the location of solar PV placement for household scale is still a challenge in its implementation. The construction model of rooftop solar PV can affect the investment cost and performance of solar PV. In this paper, the triangle model of rooftop solar PV on grid with PLN (PT. Perusahaan Listrik Negara) electricity network is studied in terms of technology and economics to determine the feasibility of implementing 900 VA household-scale power plants. Testing the application of solar PV technology under solar radiation conditions in the city of Surabaya, Indonesia as a case study. Calculation of electricity production, energy savings, energy sales, and energy purchases to determine technological feasibility as well Net Present Value (NPV), Benefit Cost Ratio (BCR), and Payback Period (PP) to determine the level of economic feasibility. The results of the research of 1,5 KWP (kilowatt peak) solar PV technology on a household scale are able to meet energy needs and reduce PLN electricity purchases to 0% and can sell electrical energy by 13.96% / year of the total electrical energy produced. In addition, the NPV, BCR with a value greater than zero, and PP of 8.6 is less than 15 years which is the service life of solar PV, so solar PV/ PLN on grid is feasible to be implemented for household scale power generation models.
