Rocky Mountain Power, a Warren Buffett-owned utility, is again seeking to kill off residential solar power
Rocky Mountain Power has proposed an almost 80 percent cut to the rate paid to net metered solar electricity, dropping it from the current 9.2¢/kWh to a rough average of about 2.0¢/kWh.
The futurology of solar power: robots, hackers, 5G, cheaper modules, repowering, and really cheap electricity
Module efficiencies will continue to increase, while the price of an individual module will stay the same. Not only will this hardware produce more power, it’ll work far longer — with predictions of 30-year module warranties, roughly the projected lifetime of gas assets.
Hardware and Services Brief: Cold rated lithium ion, fencing, a creative installation in Miami, more!

Government report says Trump’s solar tariff has accomplished little
The U.S. ITC has released a report highlighting changes in the domestic solar cell and module manufacturing industry, showing that while there has been an increase in domestic module manufacturing, the overall program’s success, relative to the $740 million in tariffs, has created little measurable benefit.
Let the solar games begin — more innovation on the Intersolar show floor
Plenty of innovative hardware at the show that isn’t a module, battery or racking — as well as services and the Solar Games.
Energy storage innovations and exhibitors at Intersolar San Diego
EMP/solar flare-hardened gear, storage-behind-the-PV-module and Generac made appearances at the Intersolar show in Southern California last week.
What’s the efficiency of a Tesla glass tile solar roof?
It depends. We attempt to do the math. Maybe it doesn’t matter.
Solar racking innovations on the show floor at Intersolar San Diego
Modules and batteries get all the headlines, but solar racking represents the shoulders upon which everything is built — and advances in this field are happening fast. Vertical racking for bifacial modules, new floating racking, a replacement for aluminum flashing, corrugated metal connections, and more!
Innovative solar modules on the show floor at Intersolar San Diego
In sunny San Diego for Intersolar 2020, we’re seeing a new idea on tracking rooftop solar modules, diodes moving to the cell level, two types of building integrated solar products, and some solar hot water.
