This past winter season has been the rainiest I have ever experienced in California. The good news is that the state is no longer in a drought condition. The bad news is that severe weather is occurring around the country. We are likely to continue on this trend: a polar vortex recently hit the Midwest, heavy snows on the east coast, and even Seattle was devastated with big snow storms. 2018 was the 4th hottest year on record globally. On average, the summers are getting hotter and the winters are not as cold.
But this is a show about energy — particularly solar. Although the output of solar systems can be predicted fairly accurately, weather has the biggest impact on annual energy fluctuations [side note: the biggest monetary fluctuations come from your local utility as they raise electric rates]. Several of our customers were concerned about lower energy output from their solar system in November, December and January. We pointed out that rainy weather — including smoke from wildfires — obscured the sunlight enough to make a noticeable difference in energy output. Even our customers who had battery backup systems contacted us, but for different reasons. Many of them had multiple weather-related blackouts this winter. These customers were delighted that their refrigerators, TVs, lights and heat were all still working even though their power was out.
While one cannot change the weather (unless your name is Dr. Evil), we can prepare for a changing climate. Please listen up to this week’s Energy Show as we discuss how weather impacts solar power system performance.
Energy is so important to our civilization that, going back to the invention of fire, there continues to be an abundance of great ideas. Unfortunately, along the way there are also ideas that simply don’t make sense – such as perpetual motion machines and concepts that violate the laws of thermodynamics. We also have dumb ideas that attempt to bring back old ways of doing things. One that really stands out is the current initiative for rolling back Corporate Average Fuel Economy standards, better known as CAFE.
The bad news about global warming continues unabated. This fall the United Nations Intergovernmental Panel on Climate Change (fondly referred to as the IPCC) sent up an emergency flare. According to Amjad Abdulla an IPCC board member and chief negotiator for the Alliance of Small Island States, “The report shows that we only have the slimmest of opportunities remaining to avoid unthinkable damage to the climate system that supports life, as we know it.“ Obviously, small island states are at the most immediate risk. But if the earth’s warming trend continues, many populated areas around the globe will essentially be uninhabitable. (more…)
These days you can’t watch TV, read a news story or listen to the radio without seeing catastrophic fires, hurricanes, and high temperatures. The world is getting hotter. To illustrate, Death Valley recorded the hottest month ever recorded on Earth. Temperatures averaged 108.1 degrees day and night, all of July 2018. That beat last year’s record monthly temperature. This is not just a U.S. only story, it’s a worldwide issue. During the month of July 2018 record high temperatures were set on every single continent in the northern hemisphere (it was winter in the southern hemisphere). (more…)
About The Energy Show
Barry Cinnamon has been blogging about the Solar Industry since 2007.
Barry hosts The Energy Show, a weekly 30 minute talk show that runs every Saturday at 1:30 PM 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 Solar (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).
