50-year solar? Here’s how the numbers may work
The DCF from a solar project’s electricity generation increases by 46% when shifting the project from today’s standard 25-year lifetime to a 50-year time scale.
When oversized is really the right size
Researchers concluded that wind and solar generation resources that were sized at 1.5x along with three hours of energy storage would meet all but 200 hours of demand scattered throughout any given year.
This utility is paying its solar customers to adopt energy storage
The incentive program requires that the batteries be charged by the on-site solar power system in order to fully qualify.
Watch: Dragon scale solar tiles installed on Google buildings in Silicon Valley
Some 90,000 individual solar panels will generate enough electricity to cover around 40% of the electricity use in two buildings for Google.
Plastic for solar panels?
Three companies are swapping out aluminum and glass in favor of plastic to save weight and add flexibility. We look at the pros and cons.
Policy will determine if Biden’s community solar push succeeds
Three factors will need to align if we’re going to deploy 700% more community solar in the next five years.
Early results of utility scale solar+storage revenue models
Adding batteries to solar increases revenue in different ways in different places.
Iron flow battery tech shows promise for mid-duration energy storage
The ESS battery systems have a prescribed design life of 25 years, but the battery modules, electrolyte, plumbing, and other components may well last for decades longer with proper maintenance.
This yacht sets sail with solar
The 60 square meters of solar panels produces 30-50 kWh of energy per day, enough to power all of the onboard electronic equipment for around seven hours.
Massachusetts weighs SMART program changes
Some solar developers have said the proposed revisions would remove 90% of Bay State land from solar development opportunities.
