Different Characteristics

Objective: To establish a baseline about the solar photovoltaic energy systems installed in the department of Caldas, Colombia. Methodology: The solar photovoltaic installations were identified from secondary sources of information, followed by field visits to collect information on the characteristics of these systems. An evaluation instrument was designed consisting of 6 categories which was subsequently evaluated by expert peers. It was applied accompanied by interviews with owners of the identified systems. Results: 41 solar photovoltaic systems were identified and installed in 11 municipalities of Caldas. Data was collected from 28 installations with different characteristics. 50% of the solar photovoltaic systems are in the Central-South region of Caldas. 71% of the systems are mainly installed in the urban area; 64% correspond to small-scale isolated solar photovoltaic energy generation systems, with a maximum power of less than 600W. These installations have become a viable energy alternative for the region and are being used especially for lighting and the operation of household appliances in residences, hotels, restaurants, and educational institutions. Conclusions: Although regulations on solar energy installations had not been established, these systems have already been implemented in the department in a successful, but moderate, manner.

Saudi Arabia has taken major steps to shift from an oil-centered to more environmentally-focused economy. One approach made recently is to enable households to possess and generate electricity by using small-scale residential solar photovoltaic systems (RSPSs). However, the number of applications to install this technology in residences is significantly low. Social acceptance of solar energy is essential for a successful energy transition. Hence, the present study aims to examine factors that may potentially motivate or impede individuals from purchasing RSPSs based on the diffusion of innovations theory. A cross-sectional, web-based survey is conducted including 1498 participants from the five main regions of Saudi Arabia. Results revealed a good cognition level in relation to solar energy, where the majority (64–83%) of respondents are aware of the benefits. An overwhelming proportion of the respondents (97%) associate RSPSs with a significantly positive image, with no significant variation in the acceptance or rejection rates among the five areas covered by the survey (p = 0.1). The results also show high statistical significance for the differences between RSPS acceptors and rejecters in all innovation attributes (p < 0.001). However, the perception of relative advantage has a higher correlation with acceptance RSPSs. These perceived advantages were of rather long-term nonfinancial benefits, such as environmental protection against global warming and provision of unlimited power, rather than the revenue related to direct costs benefits. The study also revealed that the installation cost was the most significant barrier to adopting the RSPS, which can be a focus for RSPS dissemination policies.

Main Component

In today’s world we are going towards the major share of renewable energy to reduce the effect Green House Gases (GHG) in the atmosphere. The limitation of energy sources which produces clean energy, the rise in the pollution in the environment, and programs initiated by the Indian Government have encouraged lots of open field researches on Solar Photovoltaic Systems or Solar Energy Systems. As producing the clean and renewable energy is main component of energy sector, solar photovoltaic could be considered as an alternative in various regions. Although Solar Photovoltaic does have different advantages and can be used for various purposes, but also there are several challenges for it. This paper took a whole overview of the advantages and uses of Solar Photovoltaic and barriers in their adaptation/opportunities.

The City

The use of renewable energies is imperative nowadays. One of the ways to use clean technologies is installation of photovoltaic systems which convert solar energy into electricity, through solar plants. The country?s potential for usage of solar energy is determined by the analysis of climatic conditions. The research is conducted on the example of a small-scale solar plant - a pilot project installed in the city of Nis, concerning the analysis of the mounted system and giving the recommendations for their design with the aim of improving efficient energy use. Limitations in the installation of solar plants can occur in the case of an unfavorable position of the building where the installation is planned, and more often, the limitations are related to the investment costs and length of the repayment period of these kinds of technologies. This paper represents a promotion of sustainable electricity supply for our country and it is in correlation with the legal directives of using renewable energies.

The strategies for developing of small-scale enterprise are relying on data come from secondary sources of information especially from several research and studies reports. Small businesses are an economic activity dominating more than 95% of Yogyakarta 's economic structure. This sector has both economic and social politic strategic role. The economic function of this sector, among others, to provide merchandises and service for consumers from low to middle level of purchasing power; it contributes more than a half of economic growth and is contributive to the country's foreign exchange income. Socio politically, the function of this sector is also crucial, especially in labour absorption and in the poverty alleviation efforts. Apart from the above, small business development is basic need for Yogyakarta, which practices a specific economic system, namely people's economy. Indonesia's economic system prioritizes people's economic interest, namely that which involves public interests.

Energy saving in small-scale heat power engineering is directed to increasing the efficiency of using fossil energy carriers, electric power, and their wider replacement with alternative sources in housing and communal complex. The practical use of active solar energy systems, both photovoltaic and with direct water heating, has found widespread use. At the same time, the specificities of these systems deployment are caused by climatic and technical conditions of their application. For countries found in climatic zones with temperate and cold climate, water heating installations design is most rational when used seasonally. Low coolant potential, heat supply frequency in active solar energy systems, linked to seasonality of their operation, daytime and weather require several technical solutions. For example, solutions with the use of other equipment in form of thermal energy accumulators, heat pumps and other equipment, which in any case must be combined with a traditional source of thermal energy using fossil fuels or electric power, performing the functions of both other and emergency source of heat energy. Capacity reserving of alternative energy sources is most efficient and least energy-consuming when conducting with heat sources using gaseous or degasified fuel. The use of electric power for heat supply purpose, with few capital investments, requires from a developer significant installed capacities of heat source with a low efficiency for primary fuel. In the article one considers thermal schemes of autonomous heat supply installations for objects using modern condensing boilers of low power and along them various heat cumulating devices, supplying full year operation of equipment at heat supply facilities to get the highest efficiency of energy use.
