One Electric Utility Is Carbon Neutral Today

It’s one thing to own your utility and have a commitment to renewable energy, but it’s another thing to deliver. The municipal utility in Palo Alto, CA, set an ambitious target of 33 percent renewable energy by 2015 and to ultimately deliver a carbon neutral electricity supply. They will reach 48 percent renewable power in 2017 and met the carbon n

Can Open Standards Accelerate Community Shared Solar?

Tesla Motors recently announced that it would share its technology patents, which has put a spotlight on open source and open standards. These standards already play a huge role in the computer industry: PCs have an open architecture and the World Wide Web has open standards. Google built its business on the open source Apache server and developed the open Android operating system. In 2011, Tioga Energy released an open source solar PPA. Can open standards and open source benefit the community shared solar industry?

What’s Next in the SolarWorld-China Game of High Stakes Poker?

A few years ago, a U.S. manufacturer began feeling pressure from unfair overseas competition. The company found itself losing money and market share to Asian competitors that seemingly popped up from nowhere. The manufacturer found that the conventional remedies of cutting costs and gaining efficiencies would not help much since competitors were selling similar products below production costs and receiving significant help from their government in the form of subsidies.

Would You Rather Own or Lease Your Rooftop Solar?

On a recent trip to Australia, I noticed that very few residential solar systems are leased. The vast majority are customer owned. Talking to industry experts, some claimed more than 90 percent of residential solar systems in Australia are customer owned. This is in stark contrast to the U.S., where last year 66 percent of residential solar is leased from third-party owners like SolarCity. Why such different approaches to ownership of residential rooftop solar?

The Next Big Challenge for Energy Storage

The energy storage era is upon us. States like California and New York have adapted energy policies that will make it possible to economically deploy storage systems, while technology advancements have boosted performance and trimmed costs. For the first time in history it will become feasible to store electric energy.

Listen Up: What’s the Deal with Solar Trackers?

In the early solar PV days, trackers were a necessity to maximize the energy output from very expensive solar modules. Unfortunately, in those days trackers were mechanically complex and unreliable (remember TV antenna rotors?), and the control systems were expensive and finicky. As solar module pricing declined, the interest in trackers for small systems began to wane.

NRG Just Purchased a Consumer Solar Gadget Company. Can You Make the Same Solar Marketing Play?

By now you’ve probably heard the news that pro-solar energy giant NRG is purchasing Goal Zero, a relatively tiny solar consumer electronics company. But why? NRG is a huge residential and utility scale solar integrator, while Goal Zero sells enough solar PV to power maybe a single NRG utility project. Of course, the answer is that NRG isn’t buying
