The Solar Power World Top Solar Contractors list includes Grass Valley based California Solar Electric Company.

GRASS VALLEY, CA — With renewable energy expected to be the fastest growing source of U.S. electricity generation for at least the next two years, local solar installer Cal Solar is happy to be contributing to the country’s energy mix. Cal Solar has been recognized by Solar Power World magazine for its installation efforts, achieving a rank of 313 out of 415 solar companies on the magazine’s 2019 Top Solar Contractors list.

The Top Solar Contractors list is developed by Solar Power World to recognize the work completed by solar contractors across the United States. Produced annually, the Top Solar Contractors list celebrates the achievements of U.S. solar developers, subcontractors and installers within the utility, commercial and residential markets, and ranks contractors by kilowatts installed in the previous year.

Solar Power World enjoys assembling the Top Solar Contractors list each year, and our 2019 edition features hundreds of companies making big impacts in local energy markets,” said Kelly Pickerel, editor in chief of Solar Power World. “Solar power is becoming competitive with traditional electricity sources in more markets, and cities and states are demanding more renewable energy options. It’s a great time to be a solar installer, and we’re happy to highlight the best installation companies in the country on our list.”

Auburn Presbyterian Church is all set up to harness energy from the sun with solar panels recently installed by California Solar Electric Company.

The church was built in 2000 and members first considered solar about six years ago.

“At the time they thought it was not feasible, that it was too expensive, not cost effective,” said Pastor Paul Bagai, who has been with the church for three years.

The church recently decided to revisit the idea and take bids, ultimately choosing Cal Solar for the job.

“Their bid was lower, and the panels were more superior,” Bagai said. “(The array) is not intrusive, we needed less panels, it was less money, and more effective.”

The project was complete in two days. “That’s just by planning it out properly with the crew,” said Cal Solar electrician and lead installer Reid England. “It’s streamlined coordination and logistics. It was a straightforward project.”

“And they were on time, efficient, on top of everything,” Bagai said. “They were contacting us every day with updates, contacting Placer County about the permits. I was really pleased with every part of the service they provided.”

Now for looking forward to the energy savings.

“How we priced it out, it’s going to take about six to six and a half years to break even,” Bagai said. “But that’s at the current rate. Rates will be going up and up. It will more likely be about five years for that breaking point.”

In the first three months of the year, the U.S. installed 2.7 gigawatts of solar PV, making it the most solar ever installed in the first quarter of a year. With the strong first quarter, Wood Mackenzie Power & Renewables forecasts 25% growth in 2019 compared to 2018, and it expects more than 13 GWDC of installations this year, as reported in its new “U.S. Solar Market Insight Report.”

The news comes after the United States surpassed 2 million solar installations in May.

“The first quarter data and projections for the rest of the year are promising for the solar industry,” said Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association. “However, if we are to make the kind of progress we need to make the 2020s The Solar Decade, we will need to make substantial policy and market advances.”

The largest share of installations during the record-breaking quarter came from the utility PV segment, with 1.6 gigawatts coming online, making up 61% of PV capacity installed. The report notes that with 4.7 gigawatts of large scale projects under construction, 2019 is on track to be a strong year for utility PV, with 46% growth over 2018 expected.

“Voluntary procurement of utility PV based on its economic competitiveness continues to be the primary driver of projects announced in 2019,” said Wood Mackenzie senior solar analyst Colin Smith. “While many states, utilities and cities have announced or proposed 50 or 100% renewable energy or zero-carbon standards, the announcements have not yet resulted in an uptick in RPS-driven procurement,” added Smith.

The residential market experienced annual growth as well.

According to the report, the U.S. saw 603 megawatts of residential solar installations during the first quarter, up 6% annually.

“Despite steady installations in Q1 2019, the residential market is still highly reliant on legacy state markets, such as California and the Northeast, which have seen only modest to flat growth over the past several quarters,” said Wood Mackenzie solar analyst Austin Perea. “As these major state markets continue to grow past early-adopter consumers, higher costs of customer acquisition will challenge the industry to innovate product offerings and diversify geographically.”

In fact, the report notes that 29% of residential capacity in Q1 2019 came from markets outside the Top 10 solar states by capacity, the highest share for emerging markets in industry history.

The non-residential segment, which represents commercial, industrial and public sector distributed solar, saw 438 megawatts of PV installed on the quarter, which was down on both a quarterly and annual basis. According to the report, this is largely a result of state-level policy reforms in historically strong markets for the segment including California, Massachusetts and Minnesota. The authors point to new community solar mandates in New York, Maryland, Illinois and New Jersey that will help reinvigorate the segment beginning in 2020.

Total installed U.S. PV capacity will more than double over the next five years, with annual installations reaching 16.4 GWDC in 2021 prior to the expiration of the residential federal Investment Tax Credit (ITC) and a drop in the commercial tax credit to 10% for projects not yet under construction.

Key findings from this quarter’s report include:

  • In Q1 2019, the U.S. solar market surpassed 2 million installations – just three years after the market surpassed the 1 million installation milestone. The industry is expected to hit 3 million installations in 2021 and 4 million installations in 2023.
  • In Q1 2019, the U.S. solar market installed 2.7 gigawatts of solar PV, marking the largest Q1 ever recorded. This represented a 37% decline from Q4 2018 and a 10 percent increase from Q1 2018.
  • Residential solar continues its modest rebound, with a third consecutive quarter of more than 600 megawatts of installed capacity.
  • Non-residential PV saw 438 megawatts installed – its lowest quarter since Q1 2017 – as policy shifts in states like California, Massachusetts and Minnesota continue to hamper growth.
  • There were 1.6 gigawatts of utility-scale solar installed in Q1 2019, accounting for 61 percent of U.S. capacity additions this quarter.
    Wood Mackenzie Power & Renewables forecasts 25% growth in 2019 compared to 2018, and it expects more than 13 GWdc of installations
  • Total installed U.S. PV capacity will more than double over the next five years, with annual installations reaching 16.4 gigawatts in 2021 prior to the expiration of the residential federal Investment Tax Credit (ITC) and a drop in the commercial tax credit to 10% for projects not yet under construction.

California’s wildfires may be the best thing to happen to home batteries

Article By Michael J. Coren,


Pacific Gas & Electric (PG&E) may leave millions of Californians in the dark this summer. The alternative is worse. Last summer, power lines sparked wildfires in remotes areas of the Sierra Nevada mountain range that killed at least 100 people, some still trapped in their cars, as fires consumed whole towns and more than 1.5 million acres.

The state’s bankrupt utility, which is facing a $30 billion bill (paywall) for wildfire damages, according to filings with regulators, see few options but to intentionally cut off power for millions of people during days with high fire risk. The intentional blackouts will be the largest in US history, reports the Wall Street Journal (paywall).

Such “Public Safety Power Shutoffs” aren’t going away. As transmission lines age and electricity loads increase, the risk grows that a new wildfire will break out. Power lines ignite fires after branches brush against them, or transmission poles snap, leaving live wires. Clearing trees and brush can take years, and improving infrastructure even longer. That’s compounded by extreme weather driven by climate change, which has turned America’s western forests into furnaces in waiting. Years of extreme droughts, followed by torrential rains, have left California’s wild lands full of dead and dying trees, as well as fresh growth to fuel new flames.

PG&E’s guidance to prepare for wildfire season (pdf) has little on offer: stay with friends and relatives, test your flashlights, and buy a generator. What it hasn’t promoted until recently is batteries (the utility’s page on self-generation warns batteries are “not likely…[to] save you money over the long-run”). But in a first this May, PG&E lawyers testified to regulators that the utility is proposing home batteries as a primary measure to cope with the expected blackouts. PG&E sent a statement but did not answer questions directly when contacted by email.

California’s wildfires appear to be supercharging a national trend. Solar installers are now retooling as battery installers.

The market for residential batteries remains is small — only a few hundred megawatt-hours were installed in 2018. But it’s growing tenfold year-over-year, reports Wood Mackenzie Power & Renewables. Home solar company Sunrun has installed 5,000 of its Brightbox systems — solar panels and lithium-ion batteries with eight to 12 hours of backup power — in the US and expects sales to double this year. “We are seeing increased consumer awareness of outages due to [the California] wildfires and receiving more questions from customers about home batteries,” said spokesperson Georgia Dempsey of Sunrun.

That’s the pattern after most natural disasters, says Nick Liberati of EnergySage, an online marketplace where people buy and sell home solar panels and batteries. After massive hurricanes struck Texas and Florida in 2017, EnergySage saw installations of the systems surge on its platform. Similarly, in Puerto Rico, record numbers of the island’s residents installed home battery systems after Hurricane Maria cut power for months. The pattern appears to be holding in California. Liberati says between July 2018 and March 2019, customer interest in energy storage on its marketplace rose 11% within PG&E’s service territory, more than double the national average.

Local installers in California are responding to a spike in solar panel and battery inquiries. “It’s definitely increasing the conversation around batteries,” said Martin Webb, [Commercial Manager] for California Solar Electric Company in Grass Valley near last year’s wildfires. “People want to explore anything to get out of this relationship [with PG&E] they feel is very one-sided.” While many conversations hasn’t yet turned into installations, he suspects that may change once people experience being without power for days on end.

Scott Laskey, founder and CEO of Sandbar Solar in Santa Cruz, said a surge in installations is “imminent.” He’s seen a steady increase in customers installing solar and battery systems, and more firms opting to install batteries instead of generators. “Everyone is preparing for it,” he said. Laskey himself ended his connection with PG&E last year. After building a new 11,500 square foot warehouse, he was facing $70,000 in utility connection costs, a year-long wait, and $1,000 monthly electricity bills. Instead, he installed a solar and battery system that he says cut his monthly energy bill to zero except for a $9 natural gas charge. He expects it to pay for itself in the coming years. It may even prevent the next wildfire.



California Solar Electric Company has joined in supporting the Western Farm Workers Association, an independent, private membership, volunteer organization covering the Sacramento Valley region that includes five counties: Yuba, Sutter, Colusa, Yolo and Butte.

“Our mission is to eradicate poverty in all its forms,” said association Operations Manager Juan Meleza. “We focus in large part on working men and women.”

Meleza says that is especially true in the summer months, as this includes the many low-income farm and seasonal workers.

“Some members are very transient, like the migrant workers,” Meleza said. “We’ve averaged about 1,000 members a year over 33 years. But we have 200 to 300 that we’re in contact with.”

Other members include house cleaners, fast food workers, retail workers. Voluntary membership dues are 62 cents a month.

“It’s tradition here,” Meleza said. “There is an organization of our type on the East Coast. Back in 1972 they decided to give an hour’s wage for dues for their organization. They were potato graders. It is held in tradition.”

Further support, whether monetary, supplies or service donations, are welcome.

“We have a free of charge benefit program,” Meleza said. “So what we need first is food, clothes, doctors and other businesses to provide care and services.”


The Cal Solar team has collected and delivered items to the association and plans to continue to do so. After hearing Meleza speak at this year’s May Day event in Nevada City, Cal Solar Electrician Mark Cousino was moved to share with the team what he described as truly reprehensible working conditions that some harvesters of our food can face.

“I went to the rally and what Juan said left an indelible mark on me,” Cousino said. “We need big improvements as to the needs of the farm workers.”

This is not the first time that Cousino has stepped forward to help people. He has gone to Haiti and Kenya to help build water filter factories, worked with people to stop fracking in Appalacia and with the Fight for 15 in Kansas City.

“I am working with WFWA because it is important that workers of all stripes not only organize in their own workplace but also for those workers who suffer the most in this capitalist world,” Cousino said. “It is important to me that we stand strong by supporting those organizations that are providing material relief for the most oppressed.”


Western Farm Workers Association operates daily, year-round and does not take any government funding.

“Cal Solar did a collection because this time of year in the valley, agriculture being the main industry in the region, there is a lot of farm work right now, it’s the season,” Meleza said. “Yuba County farming season opens the first of May and goes to about late September or mid-October. People come here to work from all over the world.”

Meleza said there are farm worker housing camps. “California owns and operates these migrant centers,” he said. “Due to the nature of the pay, the state of California has acknowledged that farm workers don’t make enough to be able to afford housing. So, it’s interesting, which is why I’m drawn to this work… my life is dedicated to this effort. At the end of the day it’s an economic thing, you need labor that will work for that pay … cheap labor. In the summer months, our teams go out to the camps with food, clothes and supplies they can’t afford to buy for themselves.”

“Donations of businesses like Cal Solar are really remarkable, it’s really amazing,” Meleza said. “We are building a small constituency of supporters in Nevada County. Businesses can join our members through donations.”

GRASS VALLEY, Calif. April 23, 2019 – On Saturday, April 6th, NCSOS opened the doors of the Main Street Center at the Nevada County Fairgrounds and the Northern Mines Building and welcomed approximately 2000 visitors to the 4th STEAM Expo 2019. Inside, students were able to compete in on-the spot robotics competitions, experience hands-on math challenges, create with 3D printers, assemble and launch paper hot air balloons, code and control robots, experience science-based art projects and play musical instruments from flutes to tubas. Families and other visitors enjoyed perusing student competition displays, local classroom STEAM art projects, free bicycle tune-ups by local students, musical performances by our local youth, and much, much more.

New this year was the partnership between NCSoS and the Nevada County Tech Connection, Economic Resource Council and Cranmer Industries in bringing local industries raising awareness of the link between educational goals and dreams and the career opportunities provided by local businesses and organizations. Students were able to experience green screen video making, create original art, learn how to separate soil through sifters, learn about the local watershed, wear 3-D virtual glasses, see the power of solar energy and so much more that we haven’t listed here.

Since its first year, NCSOS still maintains the steam education philosophy of a STEAM framework for teaching is based on natural ways of learning, customizable for ALL types of students and programs and is FUNctional! Shifting to a STEAM perspective means understanding learning contextually; not only in terms of having a framework that illustrates where the subjects overlap, but also in providing a living and adaptable learning structure for ever-changing personal and global development.

Planning for the Expo began by reaching out to Nevada County schools, local businesses, community members, and others who use or have vested interests in the type of educational opportunities STEAM encourages. The response is growing every year, with this year being the largest yet for having hands-on activities for attendees to experience. Students brought in their science projects, investigations, and problem solving challenges in the categories of Scientific Inquiry, Rube Goldberg machines, Environmental/Agricultural Innovation, Science Fiction, Robotics/Computer Science, Reverse Engineering, Invention, Art, and Problem Solving and Design in Math. These students proudly delivered their products to the event site to be judged. On the eve of the Expo, county board members, retired teachers, community members, principals, local engineers, and NC Arts Council members evaluated and scored each and every eligible student submission.

The NCSOS STEAM Expo 2019 closed with an awards ceremony during which over 50 students were recognized for their work in each STEAM category. In addition, student winners who participated in the TechTest Jr. math competition held in early March were recognized. Congratulations to all the category winners, schools and organizations who brought in their amazing hands-on exhibits. Forty-five Leonardo Da Vinci Awards were given for outstanding artistic communication of the students’ processes and products. NC Tech Connection awarded the winner of a raffle competition with a new drone. The Nevada Irrigation Department and Nevada County Engineers’ Association distributed cash awards for the top three student submissions that demonstrated excellence in engineering, and three projects were selected to move on to the California State Science Fair to be held in Los Angeles in April.

NCSoS would like to thank our sponsors for their support (many of whom were exhibitors at the STEAM Expo): American Association of University Woman (AAUW), AJA Video Systems, Autometrix, California Solar Electric Company, Geo-Logic Associates Grass Valley, A Belden Brand, Grass Valley Police Department, Music in the Mountains, Nevada Irrigation Department, Nevada City Film Festival, Sierra Soil Biology Association, Sierra Streams Institute, South Yuba River Citizen’s League (SYRCL), Telestream, and Traitware. I would also like to thank the entire STEAM Expo 2019 Committee, all volunteers who came to help set-up, break-down and judge some of the exhibits.

STEAM Expo 2020 has been tentatively scheduled for March 28, 2020! Details will be rolled out in the fall, but all information needed by teachers, to prepare students for STEAM Expo 2020, can be found at http://www.nevcoexpo.org.

See you next year!
