摘要：The application of the On-grid PV power systems is currently experiencing significant increase and expanding vastly as an alternative source of energy provider for different buildings in Palestine. In the Palestinian territories most of the electricity is provided by the neighboring countries which imposes burden on the Palestinian economy due the insecurity of the electricity supply and fluctuation in its tariff especially in the last years. Palestine is very rich in the solar resources with an annual average of 5.4 peak sun shine hours and has a great potential for PV powered projects, this paper presents a 12-month-long performance evaluation of the 7.68 kWp grid-connected PV systems on the rooftop of each of the three schools in Palestine: Al-Razi Boys School, Almueh Boys School & Khawleh Bent Al Azwar Girls. The performance of implemented PV systems show that the average performance ratio was 78 %, the average annual energy produces by each system equal 10.930 MWh/year. The results of economic analyses are encouraging to intensify the use of such PV school systems since the payback period of such a system is less than 5 years, the cost of kWh produced is around 0.1 US $, the internal rate of return around 20%. Besides these results, this paper presents also the impacts of PV school systems on the electric grid represented in decreasing the losses, and raising the voltage level, and the effect of PV systems on the environment.
其他摘要：The implementation of the tasks envisaged by the National Security Strategy provides for the creation and implementation of projects aimed at the formation of the appropriate infrastructure of the regions. The most important component of the regional infrastructure is the energy one, which ensures the solution of urgent problems of the population and enterprises of the regions in obtaining energy and heat supply services. The achievement of the abovementioned goal is provided by introduction of investment projects, the implementation of which makes it possible to obtain cost advantages by consumers of services. Analysis of these projects' implementation programs over a long period of time confirms the significant cost advantages, the importance of which is determined by its social significance. The purpose of this paper is studying issues aimed at analyzing, assessment and shaping the cost benefits of the introduction of energy-efficient innovative technologies for heat-saving at enterprises of the public utilities sector. The study methods for this issue include the cost-benefit analysis, the cost efficiency assessment, tabular and graphical methods, which allow visualizing the structure of the economic effect and identifying its features. The paper presents the structure of the cost advantages gained by consumers that introduce innovative energy-saving technologies. The study revealed the features of the cost benefits formation, their structure, characteristic of these technologies. The paper draws a conclusion about the effectiveness of these projects, confirmed by the results of calculations, for consumers of services. Materials of the article are of practical value for professionals engaged in analysis and evaluation of energy/heat conservation projects, as well as for organizations that implement project outputs when comparing future benefits and costs as opposed to alternative technologies.
