1. Introduction

Renewable energy is a solution for reducing the demand on and air pollution from traditional energy systems. As on-site sources of clean power, solar energy systems can reduce greenhouse gas emissions and air pollution, increasing energy security and creating local jobs. Solar electricity systems (such as, photovoltaic) also have the potential to generate power when it is needed most on hot summer days – thereby relieving strain on the electricity system and reducing the risk of blackouts. Solar PV is emerging in urban and peril-urban sectors and rooftop PV has a huge potential. Ministry of New and Renewable Energy (MNRE) as well as other state level agencies are coming with various rooftop programs and certainly private developers and integrators are looking this as one of the market and opportunities. To develop a sustainable model for our Indian solar cities, we also need to concentrate in promoting the green buildings. Green building is the practice of maximizing the usage of a building's resources i.e., rooftop solar photovoltaic system, solar water heater etc. while reducing the environmental impact throughout its life cycle. Jawaharlal Nehru National Solar Mission (JNNSM), Phase – II has been launched to promote the use of solar energy to households level. Various solar PV systems have been installed across the country to meet the energy demand and to generate the clean and green energy. PV systems have been deployed in India for electrification where grid connectivity is either not possible or, extending the grid connection to that point is not cost effective and feasible. But in urban or, semi urban area, a large rooftop potential is available which otherwise is not used for any purpose, can be used to install the kilo-watt (kW) scale PV plants to cater the energy need hence reduce the extra burden on the transmission and distribution line which otherwise have to be redefined and redesigned due to increased load demand. There are several tools available to estimate the solar rooftop potential, although there is a need of developing more accurate, user-friendly, intelligent and efficient tool which would be India specific and meet the requirements of end users and planners, which can help in preliminary assessment of site specific rooftop solar PV potential. Hence, we are proposing to develop a web based GIS tool for estimating the potential of rooftop solar power.

1.1 Purpose

The purpose of this Software Requirements Specifications (SRS) document is to provide a detailed description of the requirements for the Web-GIS solar power estimation tool. This SRS will allow a complete understanding of what is to be expected of the Web-GIS tool. The clear understanding of the Web-GIS tool and its’ functionality will allow for the correct software to be developed for the end users (here, the stakeholders) and will be used for the development of the future stages of the project. This SRS will provide the foundation for the project. From this SRS, the Web-GIS tool can be designed, constructed, and finally tested.

This SRS will be used by the research team, software engineers and GIS consultants for constructing the Web- GIS tool. The software engineers and GIS consultants will use the SRS to fully understand the expectations of

Client-Server The client-server model is a distributed application structure in computing that partitions tasks or, workloads between the providers of a resource or service, called servers, and service requesters, called clients.

Cloud Computing Cloud computing is a colloquial expression used to describe a variety of different types of computing concepts that involve a large number of computers that are connected through a real-time communication network (typically the Internet).Cloud computing is a jargon term without a commonly accepted non-ambiguous scientific or, technical definition. In science, cloud computing is a synonym for distributed computing over a network and means the ability to run a program on many connected computers at the same time. The popularity of the term can be attributed to its use in marketing to sell hosted services in the sense of application service provisioning that run client server software on a remote location. Crystalline Silicon Mono-crystalline silicon (c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells. Poly-crystalline silicon or, multi-crystalline silicon, (poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient.

1.5 Overview

The SRS is organized into two main sections. The first is ‘The Overall Description’ and the second is `the Specific Requirements’. The Overall Description will describe the requirements of the Web-GIS solar power estimation tool from a general high level perspective. The Specific Requirements section will describe in detail the requirements of the system.

2. The Overall Description The general factors are described here affect the product and its requirements. This section does not state specific requirements. Instead, it provides a background for those requirements, which are defined in section 3, and makes them easier to understand.

2.1 Product Perspective

2.1.1 Detailed Methodology The methodology of the proposed study is elaborated in the steps below:

  • Preparation of GIS base layers: The satellite images for a specified area of Chandigarh city will be procured and required image processing is done for the images to create digital elevation model as well as creation of required vector data such as building footprint, road network etc. The ground survey will be conducted to validate the actual roof information with processed data on a sampling basis.
  • After preparing GIS base layers, the solar radiation available on building rooftops will be estimated by using any desktop GIS products having Spatial Analyst function. To do this, a Digital Surface Model (DSM) of the city will be built. Then will have to take the bare earth DEM and overlay that with the building heights using attributes available in the building footprints, which results in a three dimensional surface model of the city. On the basis of this prepared surface, the solar radiation tools will be used to calculate the solar radiation availability for each rooftop.

The solar radiation tools allow the analysts to model incoming solar radiation and take into account numerous factors, including variation in elevation, orientation (slope and aspect), the shadows cast by topographic features and changes with time of day or, year. The resultant output will be validated with existing solar resource datasets (including satellite derived meteorological data an

  • After completing the analysis in desktop GIS software, the resulted solar radiation map will be published as a ‘map web-service’ which consist of base layers, an address locator and geo-processing tools, and other layers of interest (e.g., rooftop area, solar radiation, possible system size and its cost considering various SPV technologies such as Crystalline and Thin-Film, available incentives information on SPV systems both at national and state level etc.), on an Open-Source GIS Server for use by the users of this proposed Web-GIS tool. Since, the solar radiation calculations may take some additional time to complete, therefore it is suggested to pre-process the analysis of solar radiation data in order to deliver a faster and efficient web application.
  • Wrapping the analytics into an easy-to-use Web-GIS tool will be the next step. Presently there is great potential in new user interactive Application Programming Interfaces (APIs) such as, JavaScript which is a client-side technology, rendered by a web-browser. Using any of these advanced APIs will give the developers the capability to combine GIS based web services from a GIS Server with other web content and display it in a fast, visually rich mapping application that can be deployed over the web or, to the desktop.

2.3 User Characteristics
  • Educational level of Web-GIS Solar Tool – Low
  • Experience of Web-GIS Solar Tool – None
  • Technical Expertise – Little
2.4 Constraints

Since, the proposed Web-GIS Solar Tool to be developed using Open-Source environment, therefore following are the limitations pertaining to the selected technology:

  • Availability of very-high-resolution satellite imagery is important for better mapping accuracy;
  • Detailed Digital Elevation Model (DEM) or, Digital Surface Model (DSM) using LIDAR approach (which is a 3D modeling) can give more precise information, but it cannot be used here due to its very high cost implications;
  • The proposed tool will give only the macro-level information about the city for rooftop solar PV potential to the users such as annual electricity production, energy savings, simple payback etc. It will also include add-ons like guiding people through incentives, approved vendors and installation procedures;
  • System sizing and Installation cost of PV System will be assumed by considering selected PV technology (i.e., mono and poly crystalline material based PV modules).
  • Incentive and other information will be based on latest updated secondary information only. This module will be comprised certain predefined values. Since, open-source GIS technologies give limited flexibility for the user’s input based calculations; therefore, the proposed open-source web-GIS tool will have limited flexibility for the users such as, Analysis of potential PV system for a particular building while considering variations in PV cost per watt, incentive in-term of capital subsidy etc.
  • Due to limitation of open-source GIS platform, addition of new GIS features/objects such as any new buildings into the proposed web-GIS tool would be difficult through user interaction, however inclusion of few latest information to the map/datasets such as any new installation etc. will be possible by the site administrator of this proposed tool having prior knowledge of GIS and the city;
