“…High humidity is followed by low temperature and lower solar radiation values [ Figures 5 and 6]. These results are in agreement with Ettah, et al [11] that increase in solar flux is observed when relative humidity is low. …”

“…Again from the graph, the control panel has more output power than the dusty panel because of the accumulated dust on it. Hence high level of solar radiation leads to high power generation (Ettah et al, 2011) Figure Again from figure 5, increase in solar radiation favours increase in efficiency as seen in figure 5 above which inturns favours the over all output of PV module. The control panel has it all time efficiency to be 86% against 59% for the dusty panel.…”

During the dry season, dust particles on photovoltaic modules (PV modules) are a regular occurrence in Calabar, Cross River State. This dusty condition or environment is caused by the migration of dust particles from the Sahara region via the east-west wind. The concentration of dust on PV modules has an impact on the overall performance of solar energy systems. This research looks into the effect of dust particles on the output power of solar modules. This investigation was carried out by subjecting 80-watt monocrystalline PV modules to an outdoor experiment and analyzing the changes in current and voltage from the control and dusty PV modules with a digital multimeter. Other environmental factors such as relative humidity, ambient temperature, and solar radiation were also measured with a hygrometer, thermometer, and solar power meter respectively. Appropriate formulars were employed to calculate output power and efficiency. Dust particles on the surface of PV modules dramatically reduces the quantity of sunlight that penetrate the panel by 21.10%, resulting in a drop in the system's overall output power. The study emphasizes on the importance of frequent cleaning and maintenance of PV systems.

“…It is investigated the relationship between solar radiation and current, voltage and efficiency of solar panel. Solar radiation is evidently a determining factor when it comes to studying the natural potential of solar energy as a source of renewable energy (Ettah et al 2011). Which has analyzed the effects of component costs, FiTs (feed-in tariffs) and carbon taxes on grid-con-nected PV systems in Malaysian residential sector using the HOMER (Lau et al2016).…”

Land is a big issue in population dense country like India to implement large scale PV plant, whereas Grid-tied PV system is more economic than off- grid system in long run. The solar energy mission of the country will be success- ful if more and more small-scale rooftop plant will be developed. To address this issue and to find out different aspects of small-scale rooftop grid-tied PV plants, a 1kWp rooftop grid-tied PV plant is developed and different aspects of the plant on changed climate condition are studied. The study on the plant performance revealed that panel efficiency, inverter efficiency and overall system efficiency are 12.55%, 94.94% and 11.86% respectively. Array Yield, Reference Yield and final Yield of the plant are found to be 4.74,5.002 and 4.45 respectively. Also, authors analyzed capture loss, system loss and performance ratio are found to be 0.262,0.29 and 0.89 respectively. Reduction of the overall plant efficiency due to dust accumulation over the panels with changed climate condition is 0.6% for lower radiation levels and 1.6% for higher radiation levels after 4 consecutive non-cleaning days in Kolkata. Overall efficiency drops to 6.45% from 12.545% for continuous 60 non- cleaning days. From the environmental point of view the plant generates around 1149.75 kWh of electricity and fed to the grid which in turn reduces around 0.9 tons of CO2 to mix with the atmosphere annually. Apart from that the system has been compared with the simulation study in PV sol soft- ware and the production forecast, panel temperature and performance ratio has been carried out for annual basis. The payback period of the plant is evaluated as 11 years which is far less than the total life span of the plant which is 25 years. So, the results from the study sound positive for small scale grid-tied rooftop plants.
