This second edition book details how to design reliable solar photovoltaic power generation systems from a residential system, progressing to a commercial system, and finishing at the largest utility power generation systems. By following the guidelines in this book and your local solar photovoltaic electrical codes, you will be able to design solar power systems that give many years of reliable operation. When designed well, solar photovoltaic power generation is an excellent source of electrical power that results in much lower electricity bills, the power company will even refund you for the excess energy generated by your system if it is large enough. Building a grid tied solar power system is a relatively easy task. Given the large amount of government and electrical utility financial incentives that are available, it is a great time to join in the solar power revolution that is taking place in the world today. This book is also incorporated into "Complete Solar Photovoltaics for Residential, Commercial, and Utility Systems"
