City of Davis Environmental Recognition Award: Business

Tuesday night we were honored to receive the 2017 Environmental Recognition Award from the City of Davis. Candidly, it was humbling and nerve-wracking. Here's a link to a video of the ceremony, and below are my rambling, bambling thoughts:

This is like the Academy Awards for us climate geeks, the anti-Scott Pruit. Thank you very much.

I am a solar simpleton. Credit for this award goes to the several hundred property owners we have helped go solar, and the little organization that is the sustainability heartbeat of our community, Cool Davis.

Ours is a community that greatly values sustainability. We value walking and riding our bikes. Driving cars that get good gas mileage, that perhaps are electric. We value making our own energy and growing our own food. We value recycling. We value conserving. And, with all those values, any time any of us do these things, it puts more money back in to our community, because we’re not paying more for gas or electricity or food.

Hence, sustainability to me is not just simply about reducing our GHGs and carbon footprint, but it’s about building a sustainable economy. But, our values have no value if we fail to make an investment in our community. We’re simply winking in the dark, kinda kidding ourselves. Because without an investment, our values are just that: They have no value.

I would like to thank the Council, the Natural Resources Commission, blah blah, mumble mumble.

Solar tax credit: Is death on the horizon?

This happened Monday at the Kentucky Farm Bureau:

“I would do away with these incentives that we give to wind and solar."

So opined Scott Pruitt, Director of the Environmental Protection Agency. (Operative word: Protection.)

Anybody with half a pulse and a room-temperature-plus IQ could have seen it coming. After all, it’s written into the Koch Brothers’ playbook, and the Trump Administration is hell bent on aborting anything created or supported by the Obama Administration.

As we expressed a few weeks ago, it would defy logic, economics and common sense if the Republic Congress (rubber-stamped by President Trump) killed the clean energy tax credit. Why deter the fastest growing industry and most vibrant job creation engine in the U.S.? To spite the previous administration? To appease petroleum companies?

I’ve been accused of being overly optimistic, an ignoramus, by colleagues who have seen this coming. No chance, I’d pout, they can’t be that stupid (to dis-incentivize property owners from going solar). Pollutin’ Pruitt’s gonna do it, my environmental friends bemoaned.

I hope they’re wrong. I hope logic prevails, common sense is applied, job creation and environmental protection trump ideology.

But, my posture that there’s no financial urgency to go solar — net-metering is here to stay; the tax credit is written in to the tax code through 2020; PG&E rates continue to escalate — holds less weight. Any property owner who is contemplating solar, and wants to ensure they earn the 30% federal tax credit, should act soon. Before it’s too late.

YoloShines: NAMI-Yolo

There are a lot of rewarding and fun virtues of doing what we do: Helping friends and neighbors achieve energy independence (while slashing their carbon footprint and saving thousands of dollars) is extremely gratifying. At the top (of the Repower fun/rewarding list) may be when we ask homeowners to select a local nonprofit for our YoloShines program.

And, this time we have a new twist. Repower homeowners John and Alice Provost asked if we could split our $500 donation among two organizations. Of course.

John and Alice selected the Davis School Arts Foundation (read more about our prior support of DSAF here) and Yolo-NAMI, a new organization in our basket of beneficiaries. Here's what John and Alice had to say about Yolo-NAMI:

The National Alliance for the Mentally Ill is a national organization with local chapters throughout the country, including one in Yolo County. Yolo NAMI works with cities and counties in Yolo County as well as private organizations that provide services to residents of Yolo County who suffer from some type of mental illness. This is a population that is greatly underserved and often suffers in isolation due to the nature of their illnesses. Yolo NAMI provides much needed assistance to these individuals and is a very worthy organization to support.

Thank you, John and Alice, for making our community a better place.

A clean solar panel is a happy solar panel. (But, what’s the cost of happiness?)

One of the beauties of solar panels is their simplicity: They’re static, energy generation systems ... No moving parts, content as a sloth on your roof. Like sloths, they get dirty.

It rained -- barely -- last week. Not enough to even flinch the drought, but a decent amount of wet stuff to clean solar panels. Rain is like exercise for solar panels: Painful during (our production drops because of the clouds!), but fruitful thereafter (we're clean and powerful!).

The sole redeeming residue of climate change/weird weather/drastic drought is that solar systems are generating more energy than anticipated. For example, Repower homeowners' systems over the past two years are pumping out 6-15% more electricity than we had modeled. Little moisture in the ground (read: no fog), fewer clouds, more sunshine. A great potion for solar.

As rains diminish, should I clean (my solar panels) of should I chill? Stock answer for Yolo County homeowners: Clean them -- simply spray with a low-pressure nozzle; no soap or brushes are necessary -- three or four times a year, commencing a month after the last rains. There’s a lot of dirt in the air of our agricultural community. But, upon further review ...

... A 2013 UC San Diego study revealed it's not cost-effective -- and this was pre-drought, pre-water rate hikes -- to clean your solar panels. Synopsis:

Researchers found panels that hadn’t been cleaned, or rained on, for 145 days during a summer drought in California, lost only 7.4 percent of their efficiency. Overall, for a typical residential solar system of 5 kilowatts, washing panels halfway through the summer would translate into a mere $20 gain in electricity production until the summer drought ends—in about 2 ½ months.

Let them rest like a sloth? Perhaps. Sloths are quite happy in the sun.

P.S. - If/when you clean your solar panels, here are a few tips:

- DO NOT use high pressure sprayers as they can damage the seals around the frame. 

- Wash the panels in the morning to reduce drastic temperature changes. 

- Do not scrub the panels with any harsh materials. 

- If a brush is needed, make sure it has soft bristles. 

- If you notice rapid dirt build up—or bird droppings—then more frequent cleanings are warranted.
