The Energy Show
About This Show
The Energy Show, hosted by Barry Cinnamon, is a weekly 30 minute talk show that runs every Saturday on KDOW Radio AM in San Jose California.
Every week Barry provides practical money-saving tips on ways to reduce your home and business energy consumption.
Barry Cinnamon heads up Cinnamon Energy Systems (a San Jose residential and commercial solar and energy storage contractor) and Spice Solar (suppliers of built-in solar racking technology). After 10,000+ installations at Akeena Solar and Westinghouse Solar, he's developed a pretty good perspective on the real-world economics of rooftop solar -- as well as the best products and services for homeowners, manufacturers and installers. His rooftop tinkering led to the development of integrated racking (released in 2007), AC solar modules (released in 2009), and Spice Solar (the fastest way to install rooftop solar modules).Read more »

Upgrading Your Solar System

Over a million buildings in the U.S. have rooftop solar. These systems are extremely reliable: solar panels are guaranteed for 25 years, and inverters are guaranteed for 10-25 years. Our experience as a contractor since 2001 bears out the terrific reliability record of rooftop solar.
Nevertheless, when inverters are past their expected lifetime we upgrade them to new models. Often we are able to replace two smaller inverters with one more efficient large inverter. When rooftop systems get very dirty (generally in areas without regular rainfall) we provide cleaning services. And not surprising to anyone who has ever tried to troubleshoot a home networking system, our most common customer service issue is with internet-based monitoring. To that point, current cellular-based monitoring systems have been 99.9% reliable (the only problems we have ever had have been with very weak mountain-top cell service).
Like a 15 year old car that still runs, sometimes it makes good economic sense upgrading your solar system to the latest model. The same logic applies when considering an upgrade to a new solar system. Old panels were 14% efficient, and old inverters were 93-95% efficient. New panels have 20%+ efficiencies, and new inverters are up to 99% efficient. Moreover, because of our unreliable electric grid and transition to Time of Use electric rates, many customers are interested in upgrading to a battery storage system.
