Real World Solar Economics with Tom Beach

Real World Solar Economics with Tom Beach

Great solar policy is just as important as great solar technology. Obviously we need the technologies for these products — but we also need the policies so that solar products can be cost-effectively installed. And I’m not just talking about incentives…policies related to net metering, interconnection and permitting are just as important. (more…)

Ten Electric Utility Company Myths

Ten Electric Utility Company Myths

Electric utilities got their start in the U.S. in the 1880s. Thomas Edison began transmitting DC power as he literally illuminated the world. Then George Westinghouse (with help from Nikolai Tesla) deployed a better way of delivering electricity with AC power. Both Edison and Westinghouse went on to build tremendously successful companies, aptly named General Electric and Westinghouse Electric respectively. Although dominant in the 20th century, both companies have struggled in the 21st century. (more…)

California Requires Solar on all New Homes

California Requires Solar on all New Homes


California continues to lead the country when it comes to clean and inexpensive energy. Here is an example – In May the California Energy Commission passed a rule that goes into effect on January 1, 2020 that requires solar on all new homes. The rule applies to all new homes, apartments and condos under three stories tall. The rule also includes an option to include an energy storage system (which we believe will become a standard feature with all solar systems). (more…)

What are the best solar panels?

What are the best solar panels?

What are the best solar panels? That’s a question we are asked all the time. When customers look for the “best” solar panels they consider efficiency, reliability, quality and cost. Cost and efficiency are closely related – all solar panels generate the same amount of electricity (kwh) on a per watt basis. Your appliances can’t tell the difference if they get their electrons from super-efficient panels made in the USA, or the cheapest panels made somewhere in Asia. (more…)

Battery Storage System Safety

Battery Storage System Safety

This week we’re talking about battery storage system safety. But first, a brief digression. As a contractor, the biggest safety concern that I have for all rooftop solar and battery systems is not necessarily with the solar panels or the batteries, but with fall protection. It’s an OSHA regulation that all workers must be secured with roof anchors and proper harnesses when working on rooftops. So make sure your solar contractor installs roof anchors during your installation so the people working on your roof are safe. Back to battery safety… (more…)

Solar and Storage in Hawaii with Marco Mangelsdorf

Solar and Storage in Hawaii with Marco Mangelsdorf

Solar is clean and renewable and cheap. So more solar is better for everyone…except your local utility. Keep in mind that utilities generate their profits from selling electricity and building generation, transmission and distribution assets. When electricity customers install more solar, utilities make less money. Unfortunately, utilities have the political clout to enforce their monopoly on customers who would otherwise prefer less expensive rooftop solar. The biggest battles are emerging in relatively mature solar markets. (more…)
