The incoming administration’s position on energy provides interesting insight into what is to be expected from the federal government in the next four years. The new administration will surely be friendlier to coal mining, oil drilling onshore and offshore, and fracking for natural gas.
If implemented, those strategies will degrade our natural environment, lease our public lands to their cronies at low rates, increase our transfer rate of carbon currently locked in the ground into the air as CO2, increase our contribution to climate change, and increase your dependence on the oil tyrants.
My personal response will be to enlarge the solar PV arrays at my home and business, and make certain as much of my driving as possible is in an electric vehicle.
In this way I can decrease my personal contribution to the negative aspects of the administration’s carbon-based fossil fuel plans, and minimize my financial support of the centralized energy corporations, while keeping more of my money available to invest in my own family’s future.
I recently read about two towns in California that have mandated the installation of grid-tied PV systems on newly constructed homes. This government legislation illustrates to me how far residential solar power has come. Just a couple of decades ago, solar power brought to mind one solar panel powering a flickering light bulb hanging from the ceiling of a wood cabin. And now City Councils are insisting upon solar! The passing of these laws leaves me wondering if legally mandating solar installations is a growing trend and what will this mean for the future?
The town of Sebastopol has about the same population as Port Townsend, Washington, around 8000 souls. In 2013, this quirky and decidedly liberal town passed a law requiring solar panels on all new buildings and additions with nearly unanimous support from its City Council. According to a May 10, 2013 article by Miranda Green of The Daily Beast, “Sebastopol’s ordinance orders that the solar systems must provide 2 watts of power per square foot or offset 75 percent of the structure’s electricity use.” So a humble 3.6 KW system would be required on an 1800 sq ft home.
Unlike Sebastopol, Lancaster, California is largely politically conservative. It has a population of around 150,000, about the same as the Washington State counties of Clallam, Jefferson, and Mason combined. According to Green, Lancaster was the first city in the United States to mandate solar panels on new construction. The city council was unanimous in approving a zoning code amendment requiring housing developers to add solar power systems on all new homes. This new code was initiated by the Republican mayor, R. Rex Parris, who wanted to make Lancaster the “solar capital of the universe.” The satellite photo of Lancaster above shows a segment of a housing development impacted by the legislation.
A Marketplace.org article posted on August 11, 2016, by Jed Kim addresses the question of mandating solar power. According to Kim, “Santa Monica recently approved an ordinance making rooftop solar systems mandatory for all new construction and major renovations.” San Francisco is planning on implementing similar legislation in 2017. Dean Kubani, Santa Monica’s chief sustainability officer, explained that the ordinance was approved to aid the city’s efforts to reduce emissions, “We, like a lot of other cities, are looking at greenhouse gas impacts and carbon impacts, and we’re trying to figure out how can we become carbon neutral.”
In the greentechmedia.com article, What It Really Means to Require Solar Panels on All New Buildings (June 20, 2016), Julian Spector writes, “Other municipalities have already reached out to San Francisco for more information about the policy, including Boston, Washington, D.C., Cambridge and Palo Alto.” Spector concludes, “The endgame will be cities where rooftop solar isn’t a personal challenge for a homeowner, it’s just one of many components expected of a market-ready property.”
It seems clear that mandating solar power is indeed a growing trend. However, I am hesitant to assert that solar power should be mandated for all new construction across the country. All too frequently, legislation that is meant to help people ends up presenting unintended consequences and sometimes does more harm than good. What are the possible unintended consequences of legislating solar installations? How successful are other incentive programs and commercial promotions in encouraging people to adopt solar power? If we wait for the market to come around to solar, will it happen fast enough to mitigate our climate crisis? What do you think? What questions do you have about this topic or other issues with solar power?
If you are like most environmentally conscious people, solar power has been on your radar for a very long time. You may have even developed a habit of waiting for the technology to become more solid, mainstream, and affordable; waiting for the first wave of users to help work out the kinks and develop a perfected product. Until about three weeks ago when I began my research on the Solar Agent position at Power Trip Energy, I thought we were still in waiting mode.
As my training on grid-tied PV has progressed at Power Trip Energy, it has dawned on me that the “early adopter” phase for residential solar power may have already passed. My family has always been the sort who are first on our block to embrace such things as microwave ovens and home computers, cell phones and Netflix. Thankfully, we can keep our technological early adopter self-image intact. Despite the fact that residential solar power has become so mainstream that we can now share our democratized power production with the utility grid and be paid for it at 100% the utility’s selling rate, we can still be the first on our block to invest in a flashy and affordable new solar array!
Your wait is truly over. Residential grid-tied PV solar technology has become more than a logical investment in the future livability of our planet; it has also become fiscally practical, paying for itself over time, increasing our property values, and significantly reducing our power bills immediately. Power Trip Energy was brave enough to show up early and paddle out to the big wave. Now they, I mean WE, are ready to join you in riding that wave back to shore.
What strikes me most about the super awesome community members at Power Trip Energy is their integrity and commitment to our habitat. From the electric personal cars and bicycles in our parking lot to partnering with companies that insist on producing solar modules sustainably, Power Trip Energy is making a real impact on our future for generations to come. I am honored to join them in this powerful movement and eager to share the electricity with you!

SunPower’s New Record Solar PV Module Efficiency – The Importance of Efficiency on Residential Rooftop Solar
SunPower last year verified 25.2% efficiency in a manufactured silicon-based PV cell. This year, they have integrated that cell into a manufactured PV module which attains 24.1% efficiency. When making efficiency comparisons, the cell-level efficiency is less relevant as in order for us to utilize that power, we need the cells built into a module, which will necessarily be slightly less efficient due to the space between cells, and the small area occupied by the frame.
When we are designing a system for a home’s roof, we usually need to make as much power as we can on the available roof space in order generate the largest percentage of the home’s annual energy. So using the most efficient modules available is important to us. While these SunPower modules are not the least expensive on the market, when we can put up an array with higher power rating in the same space as an average array, we can recognize relatively lower $/watt installation costs on all the other aspects of the system.
We are now commonly utilizing SunPower X-21 345 watt modules, which are 21.5% efficient at the module level. Their high efficiency, finish quality, and industry-leading warranty make SunPower an excellent choice for almost all of our clients. For example on the installation from last winter pictured above, we used the SunPower 327 watt modules to get 7.85 KW in the available un-shaded space. If we had used an average module, running ~290 watts in this size right now, that would be a 6.96 KW array in the same space, 12% less power installed for the same amount of work.
The annual Washington solar production incentive payments are based on the fiscal year from July 1 – June 30, so everybody with a grid-tied pv system is about to read their meters for the 2015/2016 year.
You will get a letter containing this form below. If you are a PSE customer, the form will be filled out for you. We are not certain what the Jefferson and Clallam PUD’s are planning this year. We have highlighted some of the important fields.
The main thing you want to bear in mind is to go read your production meter on June 30. Even if you are in PSE territory and they are going to read your meter and provide the information for you, we recommend reading your meter yourself at least annually. Then you will want to compare that figure with last year’s June 30 reading in order to get your annual production figure for this year. You will also be able to copy your DOR Tax Reporting Number from the top of last year’s form.
Unless you are among the minority of our clients who have the Made in Washington PV modules from Silicon Energy or Itek, you will use the field highlighted to report your total kilowatt-hours for the year. Although the base rate is stated as $0.15, all utilities in which we operate are or will be pro-rating this base rate due to the fact that the applications are now exceeding the available incentive pool, of 0.5% of taxable utility revenues.
In the midst of our series of 2016 Solar Tours, we bring the Jefferson Solar Tour and EV Round-Up. This will be our second year of making this Solar Tour petroleum-free. Last year, we had 6 different electric vehicles (Nissan Leafs, Toyota RAV4 EV, BMW i3, Smart EV, and Tesla) carrying tour-goers to the local solar homes.
The Jefferson Solar Tour is on Saturday July 9th, and will commence at 10 AM with tour orientation and Solar 101. The local solar homes will be open from 11 AM – 3 PM, and while this is a self-guided tour, we hope everyone can drive or be passenger in an electric vehicle. With our 10 KW PV system and Level II EV charging equipment here, we try to run these tours on 100% solar power.
Kick-off Location: Power Trip Energy, 83 Denny Avenue, Port Townsend, where you will be able to pick up maps and information, as well as ask questions of the Power Trip Energy staff.
10 AM – 11 AM “Spin Your Meter Backwards” Solar 101 workshop
10 AM – 3 PM: Tour info, Maps, & Staff available for questions
11 AM – 3 PM: Solar Homes Open for Touring
People tell us that the solar tours are the most valuable educational events we conduct. Over the years, we have created a curriculum and determined how to make a focused informational solar tour that works well for attendees and hosts alike.
For more details on the entire summer tour schedule, see http://powertripenergy.com/upcoming-events/solar-home-tours/
The first tour will involve three homes in North Kitsap (Kingston, Poulsbo, & Indianola) that are different examples of state-of-the-technology grid-tied solar PV systems.
The kick-off location for the North Kitsap Solar Tour will be the Kingston Community Center at 26159 Dulay Rd NE, Kingston, on Saturday May 14th. From 10 AM – 11 AM, there will be a brief presentation letting you know what you will see, and providing context for your site visits, maps will be available, and solar experts on hand to answer any questions. The sites themselves will be open for touring from 11 AM – 3 PM.
High solar demand, lower equipment prices, higher wattages, bring continued solar installation growth on Olympic Peninsula
There are several trends in the solar industry that are benefitting us locally, and driving our growth. We are currently installing over 60 KW per month, having installed 180 KW in Q4 of last year, and Q1 of 2016. That means in each quarter, we are installing as much solar as we did the first five years of business from 2003 through 2007.
We continue to see prices on pv modules slowly decrease, mostly as a result of global manufacturing capacity increases and efficiency gains. SunPower specifically has seen recent gains at its fourth “Fab” and is now approaching producing 1500 MW of pv per year.
So as a result of this increased manufacturing capacity, SunPower has been able to give us a fairly significant price cut recently, in addition to adding a 360 watt version of their standard residential pv module. We have been installing mostly 327’s for the last year, though now the 345’s are very close in price per watt and will make up the bulk of our designs for the remainder of the year. In cases where we want to make the most power possible, we will give our clients the option of the 360 watt product.
The increased installation rate here at Power Trip Energy also creates an interesting dynamic in terms of our pricing. With more and larger projects being installed each month, without our overhead significantly increasing, we can lower our installation charges on each job. So the lower equipment costs are actually resulting in lower labor charges as well.
The extension of the federal tax credit has removed a major deadline we were facing at the end of 2016 so we can intelligently plan for manageable growth this year. The waning state incentives should be considered, since we have about four more good summers to capitalize on those annual production payments from the state.
We don’t know how long these market conditions will persist, but we do know there has never been a better time to install a grid-tied pv system in Washington.
Are 10 Year old Solar PV Modules Obsolete?
This 10 year old array continues to produce returns with no additional investment on our part. Thanks to the Energy Edition of Industry Focus for bringing up this topic – http://www.fool.com/podcasts/industry-focus. Sean, Tyler and Taylor – I hope you appreciate my Foolish perspective.
