This report was prepared by DLR, under contract to The World Bank. It is one of several outputs from the solar resource mapping component of the a
Planning [Project ID: P146140]. This activity is funded and supported by the Energy Sector Management Assistance Program (ESMAP), a multi-donor trust fund administered by The World Bank, under a global initiative on Renewable Energy Resource Mapping. Further details on the initiative can be
obtained from the ESMAP website.
As a result of the Master Agreement awarded to Solargis for global solar resource assessment and mapping
services and the resulting restructuring of this project component, this report is the final DLR output from the above-mentioned project. Users are strongly advised to exercise caution when utilizing the information and data contained, as the results are preliminary and have not been peer reviewed. The final output from this project will be a validated Pakistan Solar Atlas prepared by Solargis, which will be published once the project is completed.
