The California Energy Commission is providing this guide as an information resource to those installing photovoltaic (PV) systems under the Emerging Renewables Buydown Program. The guides pretty much covers everything you need to know to get started with your solar array today. This is the first published draft of this guide and represents the current state-of-the-art in PV system installation. We hope that this guide is a worthwhile addition to the resources available for installers.
