“This Best Practices Guide is intended to assist commercial and government entities in the process of
organizing and executing a collaborative solar purchase. … The guide outlines a list of best practices, which together constitute a 12-step process to capture the economic and practical benefits of a joint purchase. The starting point for participating in such an effort is simply an interest in purchasing solar electricity. The best practices are intended as a resource for project planning and decision making. They provide specific actions in chronological order, with milestones to indicate when to move from one step to the next. The end goal is that regional groups of participants will have solar PV installed on their facilities at competitive prices.

Experts in the solar energy field, including those specializing in regional collaboration, helped to develop
the best practices presented here. They are based on extensive research and real-world experiences, and
are supported by case studies (one a private sector collaborative and one with public-sector participants). … Throughout the guide, we illustrate the lessons learned from these challenges, point out pitfalls to avoid, and highlight ways to streamline the process. We also provide resources, such as solicitation and procurement documents, participant questionnaires, and evaluation criteria.”
