Balance-of-System components: the nuts and bolts of streamlining system design

In the last few decades, the solar industry has been primarily focused on driving down the price of modules while driving up efficiency. However, as module prices now plummet, the mantra for the solar industry has become balance-of-system (BOS) components. Accounting for one-third or more of the cost of a residential or commercial rooftop system, the installation process is moving into the industry spotlight as the key to bringing down costs and percolating demand. While mounting equipment and other system components have traditionally taken the backseat to cell design or efficiency concerns, module manufacturers and installers are increasingly looking towards innovative solutions that streamline and standardize the installation process to bring down the overall cost of system.

This presentation will discuss innovations in BOS components — from inverters to wiring and mounting gear — and will explore how these ‘nuts and bolts’ are enabling faster installation, reducing system complexity and creating nimble operations. The presenter will also address the industry trend towards smaller and lighter components and how BOS parts are being integrated into the module itself to drive further advantages in safety, reliability and even aesthetics.
