Abstract
This project aimed to establish a performance test specification to ensure that when a PV-powered solar lantern (PVSL) successfully completed the tests, it would be expected to have an extended period of life without failure at the specified performance level. The project also aimed to establish a specification that could be used for the certification of PVSL performance. Since PVSLs are shipped worldwide, obviously the result should be global in scope so that all manufacturers in every country can use the specifications. The goal is to provide consumers with an easy visual recognition that the PVSL they intend to buy is a quality product and can be clearly distinguished from products of unknown quality.

Publication Field Performance Evaluation of Amorphous Silicon (a-Si) Photovoltaic Systems in Kenya : Methods and Measurements in Support of a Sustainable Commercial Solar Energy Industry(World Bank, Washington, DC, 2000-08)The study reviews the active market for photo-voltaic (PV) solar home systems (SHSs) in Kenya, with cumulative sales in excess of 100,000 units, and current sales of approximately 20,000 modules per year. It further identifies that small single junction amorphous silicon (a-Si) modules dominate the market, largely due to their lower retail price, relative to similar sizes of crystalline PV modules. Despite this commercial success, there is concern about the performance of single junction a-Si modules, both in terms of uneven technological quality record, and uncertain short-term degradation, which occurs when this type of PV module is initially exposed to the sun. The study confirms that modules made by two of the three companies dominating the Kenyan a-Si PV market, offer long-term performance, roughly compared to crystalline PV, confirming also that quality brands of single junction a-Si modules provide a highly cost-effective alternative to crystalline modules for SHSs, particularly for households only able to afford relatively small systems. The success of this brand, despite its considerably higher price per measured Wp, indicate that rural consumers are ill-equipped to compare the relative performance of different module brands, and that risks and limitations associated with these systems, suggest a cautious approach.Publication ICT Solutions for Energy Efficiency(World Bank, Washington, DC, 2012)The report is focused on showing a wide range and variety of ways in which Information and Communication Technologies (ICT) solutions could play a transformative role, and so the bulk of the report provides case studies of actual examples of ICT solutions already developed and in action to enable energy efficiency in three particular areas, namely, smart logistics, smart grid/smart metering, and smart buildings. Ultimately, in line with the WBG's charter, this study is concerned with the question of how ICT can play a transformative role in developing countries'climate-smart future. However, as the World Development Report 2010 recognized, this is bound to start in higher-income countries, which have the incentives (being high-energy and high-cost users), the technical know-how and the resources to innovate and implement pioneering solutions to cut their costs and their carbon emissions. Some such solutions will have applicability to the developing world; a minority right away, more year by year as technology is proven and efficiencies of scale kick in. The report concludes with some thoughts, drawn out of these case studies, on the trajectory of ICT in energy efficiency in the world generally, but especially within the focus areas of logistics, the grid and buildings, and on what these case studies might mean for developing countries and their priorities in terms of energy efficiency.Publication Energy Efficient Lighting Options for Afghanistan(Washington, DC, 2009-06)This study examines the potential options for implementing an energy efficient lighting program in Afghanistan. It analyzes the range of energy efficient options available in the region and identifies the best choices for specific market segments in off-grid and grid connected areas. Based on this analysis, it is recommended that in rural areas, where grid (local or from main network) is neither available nor likely to be available soon, lead emitting diode (LED) lights coupled with solar (photovoltaic) PV panels offer the least cost solution for expansion of energy access. In grid-connected areas, compact and tube fluorescent lamps are recommended for existing household connections, as well as community and street lighting. The analysis also shows there are numerous barriers and potential problems with implementing an energy efficiency program in Afghanistan. Therefore a phased implementation program is suggested, with careful oversight of the quality of products entering the market.Publication Photovoltaics for Community Service Facilities(World Bank, Washington, DC, 2010)In many developing countries with large rural populations and low rural electrification rates, most community health and education facilities lack access to electricity. For facilities in remote areas beyond reach of the national grid, photovoltaic's (PV) systems may offer the most practical and least-cost way to access electricity. A PV system uses predictable solar resources and has long been cost competitive with diesel generators and other alternatives. In off-grid rural primary schools and health dispensaries, for example, PV systems oftentimes are an appropriate way to run many low-power, high-value appliances and equipment, from lamps and vaccine refrigerators to water pumps, television sets, and computers. Thus, if the electricity grid is not expected to arrive in the near future or if diesel fuel is unavailable or too expensive, a PV system may offer the least-cost technology for providing electricity service. If this rapid assessment determines that PV is a viable option, it results in a brief concept for a possible project and the plan for its preparation. The project concept is discussed with stakeholders and independent specialists, including off-grid renewable energy specialists, and is adjusted as appropriate. The plan for project preparation takes into account an assessment of available information and activities to be undertaken during preparation to fill gaps and generate additional and improved data. The second phase of project development is the preparation of the PV implementation plan. This is accomplished with the assistance of several specialists, including a PV technical specialist, and involves working closely with lead organization managers and specialists, broad-based stakeholder consultations, and multiple iterations. The third phase of project development, procurements and contract management, involves securing firm financing commitments (including those for post-project recurrent costs), developing tender packages, tendering and contracting, and contract management. The fourth phase, long-term operation, is where too many projects fail. In summary, this toolkit is, at a minimum, a checklist of key issues to address in developing an institutional PV project. While it is not a technical manual, nor a substitute for using professional PV specialists to size, configure, and specify system and maintenance requirements, it offers practical operational guidance to assess, develop, and implement projects with PV systems in ways that enhance cost effective supply and sustainable post-project operations. The guidance offered herein demonstrates that the opportunities for effectively addressing the issues to establish the basis for sustainability are many.Publication Quantifying Carbon and Distributional Benefits of Solar Home System Programs in Bangladesh(2011-01-01)Scaling-up adoption of renewable energy technology, such as solar home systems, to expand electricity access in developing countries can accelerate the transition to low-carbon economic development. Using a purposely collected national household survey, this study quantifies the carbon and distributional benefits of solar home system programs in Bangladesh. Three key findings are generated from the study. First, dissemination of solar home systems brings about significant carbon benefits: the total carbon emissions avoided from replacing kerosene use for lighting by solar home systems in non-electrified rural households was equivalent to about 4 percent of total annual carbon emissions in Bangladesh in 2007. This figure increases to about 15 percent if the grid-electricity generation is used as the energy baseline to estimate the carbon avoided from the installation of solar home systems. Second, solar home system subsidies in rural Bangladesh are progressive when the program is geographically targeted. Third, there exists a market potential for solar home systems in many rural areas if micro-credit schemes are made available and the propensity to install solar home systems is very responsive to income, with a 1-percent increase in per capita income increasing the probability of installing solar home systems by 12 percent, controlling for other factors.

Publication Lebanon Economic Monitor, Fall 2022(Washington, DC, 2022-11)The economy continues to contract, albeit at a somewhat slower pace. Public finances improved in 2021, but only because spending collapsed faster than revenue generation. Testament to the continued atrophy of Lebanon’s economy, the Lebanese Pound continues to depreciate sharply. The sharp deterioration in the currency continues to drive surging inflation, in triple digits since July 2020, impacting the poor and vulnerable the most. An unprecedented institutional vacuum will likely further delay any agreement on crisis resolution and much needed reforms; this includes prior actions as part of the April 2022 International Monetary Fund (IMF) staff-level agreement (SLA). Divergent views among key stakeholders on how to distribute the financial losses remains the main bottleneck for reaching an agreement on a comprehensive reform agenda. Lebanon needs to urgently adopt a domestic, equitable, and comprehensive solution that is predicated on: (i) addressing upfront the balance sheet impairments, (ii) restoring liquidity, and (iii) adhering to sound global practices of bail-in solutions based on a hierarchy of creditors (starting with banks’ shareholders) that protects small depositors.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.Publication World Development Indicators 2014(Washington, DC, 2014-05-09)World Development Indicators 2014 provides a compilation of relevant, high-quality, and internationally comparable statistics about global development and the fight against poverty. It is intended to help users of all kinds—policymakers, students, analysts, professors, program managers, and citizens—find and use data related to all aspects of development, including those that help monitor and understand progress toward the two goals. Six themes are used to organize indicators—world view, people, environment, economy, states and markets, and global links. As in past editions, World view reviews global progress toward the Millennium Development Goals (MDGs) and provides key indicators related to poverty. A complementary online data analysis tool is available this year to allow readers to further investigate global, regional, and country progress on the MDGs: http://data.worldbank.org/mdgs. Each of the remaining sections includes an introduction; six stories highlighting specific global, regional or country trends; and a table of the most relevant and popular indicators for that theme, together with a discussion of indicator compilation methodology.Publication Global Economic Prospects, June 2024(Washington, DC: World Bank, 2024-06-11)After several years of negative shocks, global growth is expected to hold steady in 2024 and then edge up in the next couple of years, in part aided by cautious monetary policy easing as inflation gradually declines. However, economic prospects are envisaged to remain tepid, especially in the most vulnerable countries. Risks to the outlook, while more balanced, are still tilted to the downside, including the possibility of escalating geopolitical tensions, further trade fragmentation, and higher-for-longer interest rates. Natural disasters related to climate change could also hinder activity. Subdued growth prospects across many emerging market and developing economies and continued risks underscore the need for decisive policy action at the global and national levels. Global Economic Prospects is a World Bank Group Flagship Report that examines global economic developments and prospects, with a special focus on emerging market and developing economies, on a semiannual basis (in January and June). Each edition includes analytical pieces on topical policy challenges faced by these economies.
