The sun shines only at night

Engie has been selected to supply a solar power plant in Guam with 50 MWdc of generation capacity and approximately 300 MWh of storage – with the express purpose to deliver 100% of the electricity after sunset.

New England needs to floor it and increase solar deployments by over 1000%

The Brattle Group has released an analysis suggesting that New England should double its electricity output and deploy between 158 and 285 GW of zero-carbon resources if it is to meet its regional goal of an 80% reduction in greenhouse gasses by 2050.

UPDATED: Solar, and solar plus storage records *possibly/probably(not)* set in California

California CCA East Bay Community Energy has signed two power contracts at an average price of 2.2¢/kWh for a total of 225 MWac of solar power, with one of the projects containing 80 MW / 160 MWh of energy storage.

SPI Day 3: solar tools, solar modules, electrical panel upgrades, future inverters, more!

Nineteen thousand people walked the floor at the United States’ largest *energy conference* – not just solar power conference – and it is a bit sad to end, but the education, handshakes, and hardware were great.

SPI day 2: Virtual reality, energy storage, big machines, ping pong & more!

Walking the floor at Solar Power International means swimming in new hardware, smart company representatives, and new ideas. Here are a few.

On the floor at SPI – touchless snow removal, perovskite tandem cells, gapless solar modules, more!

pv magazine USA is at Solar Power International in Salt Lake City, Utah this week and showing off some hardware from the floor. And most impressive is that innovation is still happening in solar modules, but also in many other complementary technologies.

Single-axis solar tracking for the next 30%

NEXTracker has refined its successful NX Horizon single axis tracker into the rugged two-in-portrait NX Gemini. The new design opens up land once considered too rough to be developed to generate near comparable amounts of electricity, while easing land use stresses.

Small solar is getting bigger, cheaper and more efficient

LBNL’s annual Tracking the Sun report, comparing 2017 to 2018, saw module efficiency rise almost 10%, system prices decrease 5-7%, median system size increases, and significant variability in all of those data points across the 1.6 million systems surveyed.

Hardware: Q Cell and Solaria all black, Sunfolding’s summer body, NY sheep services, more!

Hardware, get your fresh hardware! SunPower is releasing energy storage, solar module pricing looks flat, and make sure to shake pv magazine hands as we walk the floor at Solar Power International in Salt Lake City next week!

Solar power installation techniques – don’t do this! (w/pictures)

Solar installation inspection results of 100 sites in Rhode Island found 50% of large-scale projects had issues, while 83% of small projects had them – with 30% and 26% of those systems having “critical” issues, respectively.
