INTRODUCTION 

 

Thank you for purchasing this Bosch Solar Energy product.  In 2011, the Bosch Group proudly 

celebrated its  125 year  anniversary, symbolizing  the company’s long-term viability and 

continued commitment to bringing “Invented for Life” solutions to market.  Bosch Solar Energy 

is the photovoltaic business operation within the Bosch Group and manufactures high-quality 

solar modules.  Our solar modules utilize  advanced technology components  to supply 

environmentally friendly solar energy for many years when correctly installed and operated.  

This document provides recommendations for the installation and  maintenance  of Bosch Solar 

Energy’s crystalline silicon photovoltaic (PV)  modules  and  also  identifies the hazards 

associated with the handling and installation of these products. 

 

Before  installing,  wiring  and  using  a  B o s c h   S o l a r   E n e r g y   module,  it  is  important  to 

thoroughly  read  this manual and understand the  instructions.   Installers  must understand  the 

basic principles of electricity and electrical apparatuses as well as article 690 of the National
