This article reports on the potential use of a photovoltaic solar system on Mantanani Island. This island has its attractions in terms of flora and fauna as well as the uniqueness of its local community. The electricity supply status of the island is minimal, and the local electricity provider only provides two units of electrical generator that only supply energy from 18:00 to 06:00. This study is motivated by the hypothesis that if the target resident can obtain a better electricity supply, they can generate higher income and improve their standard of living. This study aims to identify the status of solar energy sources, estimate the basic electrical load, and conduct a techno-economic analysis of homestay enterprises of residents. Geostationary satellite data on solar energy resources were gathered and analyzed using Solargis. The electricity load was calculated based on the daily routine activities of the residents and usage of primary electrical appliances. Techno-economic analysis was done by determining the key parameters to calculate the return on investment and payback period. The results showed that Mantanani Island had great potential for implementing a photovoltaic system, by the estimated value of the total annual solar energy and peak sun hour of 1.447 MWh/m2/y and 4.05 h, respectively. The variation in total monthly solar energy was minimal, with a range of only 61.3 Wh/m2. The calculated electrical load was 7.454 kWh/d. The technoeconomic assessment showed that the return on investment was MYR 3600 per year. However, the value of the payback period varies according to the value of the cost of capital spent. Regarding the cost of capital of this study, the shortest and longest payback periods achievable were 2.78 and 13.89 years, respectively. This calculation is in line with a photovoltaic system with a capacity of 2.2 kWp.

There is no denial that renewable energy is considered to be the most cost-competitive source of clean power in many parts of the world. Saudi Arabia’s vision 2030 aims at achieving the best by using different sources of renewable energy such as solar energy, wind energy, and others. The use of solar energy in particular for power generation will decrease the dependency on oil, and thus, decrease the greenhouse gasses. Solar panels efficiency tends to decrease with the accumulation of dust on their surface. Thus, a cleaning process requires assigning and employing labor, which increases the cost of running as well as high cost of machinery. The current study focuses on assessing and designing a simple auto self-cleaning system in order to improve the efficiency of the solar panel. The results showed that for the Al-Khobar region, Eastern Province, Kingdom of Saudi Arabia, the efficiency of the solar panels after cleaning was increased from 6% to an average of 12% at nominal temperature of 27 °C. In addition, the average power output was increased by 35% during the day time. In addition, the normal efficiency of the solar panels before cooling was between 10% to 15% at 42 °C. After cooling, the temperature of solar cells decreased to 20 °C and the efficiency increased by 7%. Moreover, the output power was increased by 31% with maximum efficiency of 32% at noon time.

Abstract The prime intention of the current research is to enhance the freshwater productivity of the solar still (SS) by using Luffa acutangula fibres (LAF). The dried LA fibres were introduced into the absorber basin of solar still to enhance the wet surface area through its porous structure that leads to augmented evaporation of water from the absorber basin. The effect of the number of LAF in absorber basin such as 10,13,14,15,16,20 and 25 on freshwater productivity was estimated. The results revealed that SSLAF with 15 fibres in the absorber basin increased the yield by 25.23%. Besides, solar still with 10,13,14,16,20 and 25 fibres in the absorber basin increased the yield by 12.27%, 17.45%, 22.04%, 22.69%, 14.64% and 4.09% respectively when compared to conventional solar still (CSS). The average thermal efficiency of the SSLAF with 15 LAF was increased by 28.35% whereas, for 10,13,14,16,20 and 25 LAF, the average thermal efficiency was increasedby 11.05%, 16.99%, 22.53%, 19.93%, 11.29% and 3.9% respectively when compared to CSS.The economic analysis resulted that the cost per litre freshwater yield from the SSLAF is 22.5% lower than CSS. Also, the payback period of SSLAF is comparatively lesser than that of CSS.

Based on experimental and theoretical studies, the authors determined the payback period for the construction of a greenhouse for utilizing slurry effl uents from a milking parlor in growing fl ower crops. Complete utilization of 4.4 tons of slurry effl uents per day produced on a farm for 640 cows requires a greenhouse for growing roses with an area of almost 0.6 hectares, which is comparable to the total area of cowsheds. The largest share in the cost of rose growing belongs to the cost of depreciation and electricity costs. Capital investments required for the construction of a cultivation facility amount to 98,612 thousand rubles, while the recovery period for these costs amounts to 8.9 years. When the milking parlor slurry is applied to the fi elds, it will be necessary to build approximately two plastic-covered lagoons to store the effl uents for six months. The cost of capital investments for the construction of lagoons is almost 30 times less than that required for the construction of a cultivation facility. However,due to the low annual economic eff ect, the payback period increases sharply. The payback period of the disposal technology for slurry effl uents from the milking parlor in case of the construction of a greenhouse and the cultivation of roses is 3.8 times less than the basic technology implying its storage and application to the fi elds. The high effi ciency of introducing liquid manure from the milking parlor into cultivation facilities makes it suitable for the construction of greenhouses at dairy farms.

In this article the technique of determination of payback period of investments taking into account capital costs and economy of means at the expense of implementation of energy saving actions for warming of external protecting designs is considered. Presented in the article the method of assessing the return on investment in the implementation of energy-efficient solutions of facade insulation is only evaluative. For more accurate calculations it is necessary to take into account the discount rate. Nevertheless, the main factors that have a positive impact on reducing the payback period of investments in the renovation of facades are identified. Only an integrated approach to improving the energy efficiency of buildings can not only reduce the cost of operation of buildings, but also provide a reduction in the payback period of investment in the implementation of energy efficiency measures.

To meet the larger demand for electricity supply, Malaysia needs to achieve two main psychosocial conditions, among others—having the awareness of renewable energy and demonstrating energy-conserving behavior. To examine whether Malaysia has met these two conditions, we recruited 225 participants (n = 109 women, n = 113 men, n = 3 did not indicate) to complete a series of questionnaires. The results showed that the public was aware of the option of solar energy but was not ready to install solar photovoltaic panels after being told the cost incurred. Furthermore, the public did not show satisfying energy-conserving behaviors. To boost the installation of solar power, increasing the public’s energy knowledge and implementing policies to reduce the installation cost might be helpful. These findings highlighted Malaysia’s low readiness for solar power and shed some light on what needs to be done to be better prepared for solar power.

Purpose The purpose of this paper is to propose and empirically test a model where different motivational drivers are used to stimulate the intention of individuals to purchase green energy. Design/methodology/approach The goal-framing theory was used as the theoretical basis to design motivational statements that activate different self-goals driving the intention to adopt green energy. A field experiment was performed to investigate the influence of three different goal triggers on the intention of purchase green energy, specifically solar systems, among households living in a major city located in the central part of Mexico. The effect of demographics, environmental consciousness and perceived risk associated to the technology functionality was also considered in explaining the probability of purchase of a photovoltaic system in a short (one year) and medium (five years) terms. Findings The goal trigger grounded on normative motivations is the most influential on the probability of adoption of a photovoltaic system. However, the socioeconomic level of the household moderates the effect this type of goal trigger has on the intention of purchase a photovoltaic system. Individuals with a high socioeconomic level significantly increase their intention of purchase this green technology if motivated by a normative goal. On the contrary, individuals with a medium socioeconomic level are mostly motivated by goal triggers grounded on economic benefits. Research limitations/implications This study was circumscribed to a particular city of Mexico. Replication of the experiment in cities of other developing countries with contrasting sociotechnical contexts and the consideration of other green behaviours and explanatory variables is relevant to confirm and complement the results of this research. Practical implications The cost of photovoltaic systems represents a major barrier to the growth of the Mexican market of this renewable energy. Therefore, the promotion strategy for solar energy must be accompanied by the design of appropriate motivational drivers depending on the socioeconomic level of the segment and the time for the investment. Additionally, public and private strategies to decrease the cost of the technology and financing programs for individual and community projects are recommended. Social implications The willingness to use green energy and contribute to the protection of the environment should spring from within consumers. To upscale the solar energy market, it is relevant to understand the dominant goals of individuals when taking the decision to purchase green energy. Originality/value This study contributes to the extant research in green marketing by proposing and testing a new interpretative framework to examine how the benefits of green energy activate the self-goals of consumers, thus influencing their intentions of adoption of green energy. A theoretical model is proposed by constructing “goal-triggers” grounded on the goal-framing theory and empirically testing in the specific case of explaining the intention of purchasing photovoltaic systems in Mexico.
