Energy Supply to Bwai Health Center at Musoma District –Mara Region Tanzania, 2017
This Proposal is an excellent initiative, which fully contributes to the approach of supplying Energy at Bwai health center ,By looking at all the energy needs of health facilities and providing technical guidance on how these can be met with renewable energy technology which is solar Photovoltaics to fills an important gap. Rural health service is an important national and international priority. However, the availability of electricity to support proper rural health services is less than adequate in many countries including Tanzania, Because renewable energy is regionally diverse, the appropriate renewable energy system will be regionally and site dependent. While photovoltaic (PV) systems have paved the way and are being deployed in most cases, several micro/mini renewable sources of electricity should be considered.
Building Integrated Photovoltaic System (BIPV) is the integration of Photovoltaic (PV) into the building envelope in the top, the facades and or may be used for the building which is built already without PV integration. That is installing or hanging of PV panel in different positron of the building. When the building is integrated with PV panel, it is used as a construction material and again save extra area requirement of installation and at the time it generates the required amount of energy for the habitants of the building is to get from free natural solar energy. Integrating BU in photovoltaic system is the aim to save the large power cost without taking large area for the installation of the photovoltaic panel since the university occupied by large number of students, workers and staffs members. The total estimated cost of initial investment for materials such as PV panels, battery, charge controller, inverter and like is $63,040. It is estimated as BIPV system total cost in the 25years life time is $176,815 which lower than that of the total national grid electricity cost by $40, 185.2 using in HOMER software implementation.

The sun releases tremendous amount of energy, which if harnessed would provide all energy needs of mankind. One of the strategies to trap this immense energy is the use of solar modules/panels. However, these solar modules need to be properly sized and installed to be able to function and generate electricity optimally. The successful installation of an off grid Photovoltaic (PV) solar system is a process that begins with a site visit to the area of installation, the determination of the client's energy needs, installation of the solar PV system, commissioning of the installed solar system and ends with user training. Every step is critical for it determines the final performance of the solar system and hence the delicate balance between a satisfied or unsatisfied client. However, the system sizing step tends to attract more attention for it determines the system size and the matching of the balance of system components and so if this is not properly done, then the entire system may not perform as intended. Most documented sizing methods tend to be too complicated and require significant computer knowledge in simulation, modeling and even programming. For practical purposes, many designers and PV installers, especially in developing countries have basic education may not be well equipped for these complicated sizing methods. Furthermore, very few have been professionally trained in PV solar system Sizing and although there are commercially available sizing software's, they are too expensive for majority of the people and even if available, they are too complicated for them.In actual sizing therefore, most untrained PV technicians use mere estimates that may not be appropriate for the outcome, more often than not is disappointing. We present a simple sizing method that can easily be learned andapplied in a simple calculation, for example in a simple excels sheet formulas for easier sizing of PV systems. The method is recommended for adoption in developing countries for faster dissemination of professional PV services in system sizing.
The limited supply of traditional energy sources, resulting in high prices of the traditional energy sources like coal, oil, natural gas etc . They have resulted in rapid development of alternative energy sources, in particular solar energy. Various types of alternative energy such as solar energy, hydroelectric energy, wind energy etc are used in day to day life which exhibits more consumption of energy sources at a very cheap rate. This also results in environment eco-friendly and resulted in less pollution. Photo-voltaic systems are very useful to create a good economic society as well as environment eco-friendly. Photovoltaic Solar Power plant price will play a vital role in the larger development of solar power generation. In this paper we deals with photo-voltaic solar power plant components as well as steps taken to design a photovoltaic system and what are the pros and cons of the systems.
