High temperature is the primary challenge in the development of solar photovoltaic (PV) systems in an arid climate. A rise in temperature diminishes the performance of the PV systems and shortens their lifespan. The goal of this manuscript is to develop an analytical model to predict the temperature of PV panels under a passive cooling system for an arid environment. Taking into consideration the link between solar panel temperature and its conversion efficiency, Kirchhoff’s and Ohm’s laws for a complex circuit were applied to calculate the heat flux in the solar panel system, and hence obtain the temperatures of each layer in the system. Closed-form analytical expressions for temperature, output power, and conversion efficiency of the solar panel were deduced and presented as functions of solar irradiance, ambient temperature, emissivity, wind velocity, tilt angle, and dimensions of fins. Comparison between the results presented in the literature and those predicted by the developed analytical model validated the presented model. Moreover, the length of the fins required for safe thermal operation of solar panels in harsh desert environment were also obtained from analysis. Furthermore, the effect of using such a cooling system on the temperature and efficiency of the solar panels was verified by using the developed model under real conditions in Dammam city during summer and winter seasons. The results showed that the optimized heat sink could raise the solar panel power by 8.7% during summer and by 6.5% during winter.

Harvesting energy from the sun makes the photovoltaic (PV) power generation a promising technology. To obtain a consistent state of charge (SOC), consistent energy must be harvested and efficiently directed to the battery. Overcharging or undercharging phenomena decreases the lifetime of the battery. Besides, the effect of irradiance toward solar in term of sunlight intensity effects the efficiency and hence, sluggish the SOC. The main problem of the solar panel revealed when the temperature has increased, the efficiency of solar panel will also be decreased. This manuscript reports the finding of developing an automatic active cooling system for a solar panel with a real time energy monitoring system with internet-of-things (IoT) facility. The IoT technology assists user to measure the efficiency of the solar panel and SOC of the battery in real time from any locations. The automatic active cooling system is designed to improve the efficiency of the solar panel. The effectiveness of the proposed system is proven via the analysis of the effect of active cooling toward efficiency and SOC of photovoltaic system. The results also tabulate the comparative studies of active-to-passive cooling system, as well as the effect of cooling towards SOC and efficiency of the solar panel.

Biologically Inspired Design

Biologically inspired design is the process of using biological systems as analogues to develop innovative solutions for engineering problems. This paper describes an effective and successful implementation of problem-driven biologically inspired design in a real-world problem. In support of the Department of Energy SunShot Initiative, a national collaborative effort to make solar energy cost-competitive with other forms of electricity by the end of the decade, solar panel designs were carried out by engineering and architectural design teams. Solar Photovoltaic (PV) systems were developed using analogical design, and more specifically, bio-inspired design. Some systems were also designed using non-biological analogues. Functional decompositions were employed as the first step in the design process, as a way to identify the key functions essential to the system’s reliability and cost effectiveness. Six key functions were identified. Analysis of the final designs by the teams showed that the solar panel system designs using biologically inspired analogues were more effective in meeting the six key functions identified during functional decomposition. Employing a combination of divergent and convergent design thinking is also discussed as a way for effective biologically inspired design. The top three designs selected for prototyping were biologically inspired and exceeded the project goal of reducing the installation and labor costs of solar PV systems by 50%.

Subject The outlook for the solar photovoltaic sector in China. Significance The EU's decision last month to remove tariffs on imported Chinese solar panels follows a US move to increase tariffs. It also comes at a time when international prices for panels are falling in response to a reduction of subsides for the deployment of solar photovoltaic (PV) capacity in China. Impacts Falling prices will stimulate further installation of solar PV capacity across the world, especially in sunny regions. Chinese manufacturers will further expand their capacity both at home and abroad. Non-Chinese PV manufacturers will find their profits squeezed even further unless they are protected by import controls. The rate of deployment of new solar PV capacity within China will decline, but still remain substantial.

Tropical Country

Indonesia is a tropical country located on the equator. The average intensity of solar radiation in Indonesia is 4.8 kWh/m2. This makes Indonesia a country with new and ren ewable energy potential, one of which is solar panel technology. The first step that must be done in the process of installing solar panels in a place is to analyze the potential of solar energy. In this study, an analysis of the potential of solar energy as a new renewable energy source has been carried out at Budi Luhur University, North Petukangan, South Jakarta. Based on the research results, the maximum photovoltaic efficiency that can be achieved is 21.45%. During the day, the efficiency of the solar panels increases along with the ncrease in the value of the voltage obtained. However, the higher the panel temperature, the lower the efficiency of the solar panel. Therefore, a cooling system is needed to anticipate this.

The perennial inadequate power supply problem in Nigeria, the worldwide call for green energy and the unavailability of grid electrical supply or difficulty in accessing it have created a need for the adoption of renewable energy such as solar PV systems. PV systems have a lifespan ranging from 10 to 25 years if well maintained but it has been observed that PV systems do not last up to their useful lifespan in Nigeria. A preliminary survey carried out showed that 71.2% of sample did not carry out any maintenance on their PV installations, 85.7% agreed that a lack of maintenance was responsible for their nonfunctional PV systems and 95% of the respondents agreed that there was a lack of maintenance on PV installations in Nigeria. A maintenance regime was developed for PV systems whereby a maintenance personnel is appointed to carry out routine or breakdown maintenance on solar panels, charge controller, battery, inverter, and cabling. The regime starts with turning off power coming from the solar panels. The maintenance of the solar panels follows; next is maintenance on all cable wiring and terminations. After all cable terminations have been checked, the battery maintenance follows. The charge controller is then checked for maintenance and subsequently, power from solar panels can be switched on to restore charging. Two protective installations were recommended in the maintenance regime namely the installation of earthing and DC circuit breakers to protect the solar system installation.

Self Cleaning

Solar panel soiling is a major barrier in electricity generation by solar Photo-Voltaic (PV) technology, especially in dust-prone cities like Kathmandu. Currently employed techniques use expensive cleaning bots, short-lived coatings or environmentally non-friendly coatings. This paper encompasses a study of a green alternative to counteract solar panel soiling. Cellulose nanocrystals (CNC) blended with Poly Vinyl Alcohol (PVA) with surface modification by Poly butylene terephthalate (PBT) and powdered silica was used to produce a transparent, hydrophobic film which could act as a self-cleaning cover for soiling prone solar panels. The film exhibited an average transmittance of 92.18% of the incident light in the solar PV working spectra (420nm-700nm). Hydrophobicity was quantified by the water contact angle (WCA) which was an average of 87.25°. The film was durable to photocatalytic and hydrolytic decay but further research is warranted before rendering the film suitable for use as a protective cover for solar panels.

Major Factors

Temperature is one of the major factors that affect the efficient of solar panels and temperature profiles on solar panel are required to optimise the performance of solar PV. A method to construct and visualise the thermal profiles of solar panel with minimum temperature measurement is proposed in this work.  Based on nine measured temperature, three different interpolation techniques are used to predict the temperature at 25 points and 81 points. The predicted temperature is then compared with measured temperature from thermal gun. MATLAB is used to reconstruct the thermal image in two different resolution, 17x17 and 33x33. Bilinear interpolation technique and resolution of 33x33 gives the best results and can be applied in industry to predict temperature profile on solar panel with minimum measurement.
