Electricity transmission pole are type of lightning required. Bhuvaneswari, R. Rajeshwari, C. Oke A. Martin A. The survey of the report of rural area has the installation of street light in needed 4. The scope of this project is to design street light using one of the renewable energies, solar panels. Developing a grid system is often excessively expensive, as it consumes excessive fuel, its running cost is pretty expensive than any other renewable energies solar energy, in this case. In addition, when an accident happens, the consequence of the accident is very crucial in grid systems.

So using solar panels for street lights is much more efficient than any other sources. This is because, the running cost is cheap, as every pole has its own solar panel, battery, inverter or controller, sensor and lamp, there is no any external input needed. The only cost needed is installation cost and after certain time, replacing the materials which are installed. The scope of the project is to design and deliver the project in a time of not more than 2 months and with the cost of up to , USD to a specific community.

Like hiring skilled workers, gathering necessary information for the design, designing the components according to the information surveyed , purchasing the components which fulfill the specifications of the design part and finally inspecting the implemented project is one of the key scope of the project. In this, the position of the poles along the road, the height of the poles, thickness of the poles should be convenient to the traffic rules of transportation.

Similarly the area coverage should be upon the interest of the community living around and should solve the problem of the community. The other key point is to make sure the components solar panels, batteries, lamps, charge contorlers and sensors should have the same specification and quality as proposed by the designer. Consultation will be given to the representatives of the community for two weeks on any case of the project.

Solar Panel based street lightning 1. For instance, depending on the solar radiation of the area, weather is it exposed to pollution, fog, rain the rating and type of the solar panel which is convenient to the site area is designed.

Similarly depending up on the geographical information, the quantity of the materials required, the power rating of the solar panels, the length and thickness of the poles and their structure, battery type and lamp type can be designed. So job announcement or similar activities should be done to hire employees.

So on the supervision of engineers, civil workers dig tranches according to the design of the poles. This task should be supervised by technicians, to check the height, thickness and the structure of the pole. According to the specification of the design that is done in the design of components part the solar panels size, power rating, tolerance for wind and type should be checked and installed.

Batteries store electricity from solar panels during day time and deliver this energy to the fixture during night. The life cycle of battery is very important to the lifetime of light and capacity of battery will affect the backup days of the lights. The battery based on its type, power specification that are specified on the design part, will be installed.

Led lights are usually used for lightning source for modern solar light. These lights provide much higher lumens with lower energy consumption.

LED lights give energy consumption up to 50 percent lower than high pressure sodium lamp HPS which is widely used as lightning source in traditional street lights. Specification should be concurrent with the specifications of batteries and solar panels as already done in the design part. So this part will be done after the erection of the pole, installation of solar panel and battery. The main functions of charge controllers are to prevent over-charging of batteries from solar panels, over-discharging of batteries to the load and to control the functionalities of the load.

In this case the street light must have auto on and off and must have at least two state of dimming function to save energy, from dusk to dawn. The Engineers and technicians should inspect or check if all the components are working properly. As a general it is checking of the proper working of the project which is solar panel based street lightning. Starting from this idea, the top bottom cost estimation is used to distribute the estimated cost to the smallest deliverables.

Labor cost i 12 Casuals working for 6 days each 15 per day 2, ii 4 Technicians working for 20 days each 25 per day 3, iii 1 contracted service Engineer during the whole project duration 3, iv Project Manager for 35 days 6, 3.

Depending on the above information, the percentage cost of each deliverable or WBS is estimated in the diagram below. Based on this, estimated duration and interrelationship of the activities are inserted into the software. The duration for each activity is calculated based on the formula below. Values for the variables a, b, m are assigned by inspection.

The projected is planned to start on December 21, and to finish on which takes 35 days of working days. The following figures show the Gant chart and the network diagram developed using the above information. Fig 2. The duration of the project is given as 35 days. The Gant chart after resource allocation to each activities will be given in the next section.

Similarly the network diagram is also given below. As in the table all the information about, early start ES , early finish EF , late start LS , late finish LF and duration of each activities is displayed in the network diagram. The critical paths in the network diagram are those with zero slacks. This is according to preliminary schedule of the project. Fig 4. Resourse allocation table The above table shows the deliverables and the resourses of the project.

Each deliverable is done by specific resource and the cost required per day of the resource is also displayed. In this project the resources are fixed and as it is observed in the table, the red color indicates, at some period with in the duration of the project, the labor resources are over allocated.

Something should be done to solve such problem. The only option is to crash the resources, as the project is resource constrianed. The result will be explained in the next sections. Similarly, the table below shows clearly the resources of each activity or deliverable and the estimated duration of each activity.

The man power of this project is, one Engineer, one Project Manager, four technicians and twelve causual workrs. The total time is 35 days, still this acording to preliminary schedule.
