Solar combined with battery storage seems like magic to many residential and commercial customers. With a million and a half systems installed in the U.S., the question is no longer: “does solar work?” Instead, customers want to know how much money they will save with a system. And commercial customers are even more diligent about accurate savings predictions. (more…)

The Commercial Solar Opportunity

The Commercial Solar Opportunity

There are there are three market segment for solar in the U.S.: residential, utility and commercial. Based on some rough math, in 2018 we expect to install 5 to 7 million solar panels on homes in the U.S. In areas with high residential electric rates, paybacks are usually in the range of 4-8 years. But the utility solar segment is much larger: about 20 million solar panels will be installed by utilities in 2018. Utilities realize that it is cheaper to generate power with solar compared to coal or nuclear generation. Moreover, the combination of solar and batteries is projected to be even cheaper than natural gas in a few years. (more…)

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…)

Success in the solar industry requires leaders with a diverse skill set. Leaders must really understand the technology’s evolution, be effective with sales and marketing, coordinate what always seem to be chaotic operations, juggle financial issues and manage a growing team. I’m always interested in learning from people who have this diverse background — and have demonstrated success in the solar industry. (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…)

Gigawatt Scale Solar Installations

Gigawatt Scale Solar Installations

We often talk about smaller solar power systems on homes or commercial buildings. On this week’s Energy Show we are discussing gigawatt-scale solar installations. The logic is simple: solar panels are getting cheaper and installation costs are declining. At the same time, utility electric prices keep increasing. When prices go up and costs go down profits can skyrocket – so it’s no surprise that there is a big market for large-scale solar installations. (more…)
