Arizona Public Service (APS) has been in my solar news pipeline quite a bit recently as they are generally whining about roof-top solar and attempting to obstruct progress and profit from other people’s investment by adding solar surcharges to monthly bills for net-metering customers who have installed pv on their homes.  At the same time, they are scrambling to meet a 2025 RPS (renewable portfolio standard) requirement of 15% with a 3% solar carve out.

It now appears that APS will install pv modules on 3000 homes (20 MW total, 6.6 KW avg for each home) and give customers a $30 per month credit on their bills for the use of their roofs.  The contract is the standard 20 years, so the total these customers will be paid is $7200 over the 240 months.

If  pv array in Arizona makes 1800 kwh per KW per year, then that 6.6 KW pv array would generate 11,880 kwh/year (at times of peak load, which is the most valuable time to make electricity.  If the average retail rate of electricity is 12.5 cents per kwh for residential Arizona electricity, then the retail value of the electricity made by that hypothetical 6.6 KW pv system is $1485 today (do you think the price of electricity might go up over the next 20 years?)   For that amount of electricity, APS is willing to pay you $360, a rate locked in for 20 years.  Hmm, thanks but no thanks.

If I am reading this correctly, it will look tempting to many, but its a very good deal for APS, and a bad deal for the customers.  I’d rather own my pv myself and get the full benefit of all the energy it produces over its life, rather than lease my roof for a paltry $30 per month and let the utility get the bulk of the benefit.  I’m thinking my sunny roof in Arizona would be worth a whole lot more than that.

Turner – Phase 5

Turner – Phase 5

This photo is of a home just outside Port Angeles with which we are very familiar.  We are familiar with this home because we have performed 5 pv installations there over the years, originally in 2006, when we put up 3.4 kw of Sanyo 190 watt modules, as pictured below.  They are now up to a total of 8 kw.  Our client views his consistent incremental upgrades as retirement investment and a hedge against rising energy costs.  This couple is also environmentally motivated, and very well known in their community for their generosity with their time for civic causes.  While we wouldn’t necessarily recommend you go about your solar installation in this way due to the increased labor costs compared to a single installation, we will be happy to work with you whatever your goals and thoughts are about pv.

Turner Array 3.4 kw Sanyo - 2006

Our standard warranty is 10 years on our workmanship.  Our initial contracts stated a standard one year warranty on workmanship, however as our installations aged, we were happy to learn that our workmanship is such that warranty issues never come up, so we gradually lengthened our warranty, and now after 12 years, we are very comfortable offering 10 year warranties on our work.

The standard inverter warranties are now 10 or 15 years, but in the early 2000’s, five years was the industry standard, and some of the inverters we sold from this era have since failed.

We recently heard from the current occupants of a home that had a system installed in 2004 that the system was not working.  Dr. Meyers, our original client who built this home, loved fishing and was tragically lost at sea shortly after the project was completed.  During our initial phase of business we sold the materials for the first 8 projects at our wholesale cost, in order to promote the technology and learn about the equipment without making a profit, and also to show gratitude to our initial clients.  Dr. Meyers’ project was one of those initial projects.

Upon arriving to troubleshoot, Steve determined the inverter had failed and was able to install another used SunnyBoy 2500 that had been originally installed on my home, for use with an array that has now been upgraded with more modules and a larger inverter.  There is no remaining warranty on this inverter and there is no telling how long it will last, but the system is back up and running and once again producing clean power.

Although the system is over 10 years old, has no remaining warranty on labor or inverter, the project was sold without profit, and another contractor actually performed the installation, we felt able to do this repair with no need to charge the owner for the time or materials.  Thankfully we are busy with great projects and have sufficient time and resources to take care of our clients, and we are happy to do so, especially in memory of a fine man.

Utilities should look for ways to encourage the adoption of electric vehicles, including working to increase public charging infrastructure, and recognize the opportunities for increased revenue through electricity sales to this new market.

Some people within utilities are spreading fear about lost revenues due to the uptake of distributed renewable energy generation and decreased consumption through energy efficiency improvements.  They are wasting their time decrying the inevitable, and more importantly, they are missing the opportunity right in front of them.

In an article here by Elias Hinkley, the point was made that by encouraging conversion of our transportation fleet from of liquid fuel vehicles to electric vehicles, there is a huge untapped opportunity awaiting electrical utilities.

The benefits are many:

  • the utilities can maintain revenue growth despite the adoption of distributed renewable energy and energy efficiency
  • electricity can be made locally thereby benefitting the local economy rather than oil company tyrants
  • cars would be cleaner, our cities and streets more pleasant for people who choose to breathe air
  • globally we would be contributing less carbon into the atmosphere

Wright AwayHere at Power Trip Energy, in addition to our 10 kw of pv arrays, we have two Level II fast chargers available to the public for free.  We see old friends and meet new folks every day who regularly use the solar-generated electricity we choose to give away.  It is fun to consider the amount of miles driven without these folks needing to buy gasoline.

We have been a destination for many tourists from out of the area despite the fact that our shop is not in the most convenient or desirable location for tourists.  The trnsit stop is only 1/4 mile walk from here, and we are right on the Larry Scott Trail into town.  The Broken Spoke bike shop will drop off a rental bike for people who make pre-arrangements before their visit.

In Jefferson County, the citizenry has already demonstrated leadership through the high per capita adoption of electric vehicles and solar pv.  The question now is whether we will help our leaders see the benefits of following our example, or will we allow our leaders to retain old-school thinking and impede our progress.

 

Since 2006, we have had a very generous Federal Tax Credit for solar photovoltaic equipment – a 30% Investment Tax Credit.  For most of our clients this is a straight-forward tax credit taken on Form 5695 for individuals and Form 3468 for businesses.

While many people hold the opinion that the Federal government needs to do more to support renewable energy, we feel that a 30% tax credit is generous.  The improvement we would wish for federal energy policy would be to remove the myriad explicit and hidden subsidies for the standard centralized and polluting energy sources.

This solar tax credit expires in 2016, and we see little chance of it’s extension.  So this 2016 date is a good deadline for you to install solar if you are unable to do so immediately.

For businesses, there are also special depreciation rules which can help decrease your tax burden, however these seem to change every year and during the year, so please consult your tax professional regarding depreciation of solar energy systems for your business.

If you have a grid-tied pv system and are enrolled in Washington State’s Renerwable Energy Production Incentive, it is time to make some notes for yourself.  The 2013-2014 production metering year ends on Monday, June 30th, and the 2014-2015 production year starts Tuesday, July 1st.

Many of you know the process, but for many new customers, this will be your first production payment.

Different utilities handle this metering and payment in different ways.  Some of them will take the meter readings themselves (eg PSE and Jefferson PUD), and some may rely upon you to report this reading (eg Clallam PUD).  In either case, we recommend that you also take this reading and keep track of it in order to verify correct payment.  If you have the record of payment you received from last year, this may be the best place to write it down.

All of our grid-tied pv installations have a production meter which measures the accumulated kwh output from the inverters.  This meter reading is the reading to take on June 30.  If you have last year’s reading, if you subtract that, the result is this year’s production.

We would LOVE that production figure for our records as well.  We have mentioned in the past that we are accumulating data to perform statistical analysis to learn what we can about the various brands of equipment, and the micro-climates within which we work.  While we have not been able to complete that study in a scientific manner (the number of variables is challenging) we still want the data for the systems we have installed.  Please e-mail your annual production figure, if you have it, to info@powertripenergy.com.

SunPower News

SunPower News

We recently saw a significant price decrease from the leading pv manufacturer SunPower.  They have consistently lagged behind other manufacturers with their price decreases and we are glad that this is so.  It may sound strange, but we are happy that SunPower is slow to react to market price dops and here is why – in 2013 they were able to generate $221 million in net profits of $2.6 billion revenue.  It is of crucial importance for a manufacturer to generate net profits in order to re-invest in research and development and improved operations.  Many leading pv manufacturers have struggled to maintain profitability in this very competitive market, especially in the face of continued Chinese dumping.

We also saw another big announcement from SunPower in the second half of last year, and that was the improved warranty.  They offer a full 25 year workmanship and repair/replace/reimburse warranty on their modules in addition to the industry-leading 87% power guarantee warranty after 25 years.  All of this is very strong, however there is another aspect of SunPower’s operations that make it even stronger.  They are currently maintaining a $140 million long term warranty reserve fund.  All while only showing 27 failures per 1 million modules shipped.

SunPower continues to charge a premium for their product compared to the myriad of their competitors on the low end.  Despite this higher price, for many of our clients, we feel they offer the best long term value because of the quality of the product, the industry-leading efficiency, and the financial health of the corporation.  SunPower employs about 1770 US workers among their global workforce of about 6000, and we are happy to be their partners.  Good job on the recent price decrease, it will help us install more of these high quality products and make more clean energy.

Electric Site Eval Rig & EV Chargers Springing up in Port Townsend and Silverdale

Electric Site Eval Rig & EV Chargers Springing up in Port Townsend and Silverdale

We now have a new vehicle in the fleet here at Power Trip Energy – an all electric Toyota RAV4 EV.  The lease option makes this vehicle very affordable compared to the gasoline we had been burning in our Chevy Astro and Toyota pick-up that had been handling the site eval and light work duties.  With the rear seats down, the back is large enough to accomodate a pretty good sized folding ladder for roof access.  We have just made a significant reduction the carbon foot-print of our solar installations.  Here is Toyota’s site:  http://www.toyota.com/rav4ev/

This vehicle made its first run to Bainbridge yesterday and to central Kitsap again last night, totaling 170 miles for the day, taking the opportunity to charge during meals and for two hours in between trips here at our shop.  We’ll be posting more reviews of this vehicle as we continue to get to know it.

We made a pleasant discovery last night in Silverdale.  There are 4 new EVSE stations going in at the Silverdale YMCA, which is right across the street from the mall and shares a parking lot with the Silverdale Community Center.  Two of those are Level II plugs (installation not complete) and two were on a large CHAdeMO kiosk, which was ready, though our Toyota RAV4 EV only has the Level II charge port.

Since this kiosk was not useful to us, we wound up going up the hill to The Doctor’s Clinic at the corner of Mahyer and Ridgetop Rd to use one of the Eaton Level II chargers gratis.  Thanks docs!

Usually however we will be charging at the shop, where we have 4 kw of pv that provided 75% of our annual electricity last year.  Now that we are charging electric vehicles (ours and anybody else’s, for free), we will be doubling the size of our pv array to cover the additional electrical loads.  Believe it or not we still sometimes get asked “Does solar really work in the Pacific Northwest?”  Actually yes, it works well enough to power your home and to drive your car with it.  That’s the PV – EV connection.

Here’s the RAV4 EV charging under the solar awning on this rainy day.

Plugshare.com is a useful website to locate charging stations near you, let you know if they are free or require payment, and if they are occupied or available.  http://www.plugshare.com   It is also available as an app for your phone of course.

We came back to the office after working in the field this afternoon and drooled over the beauty parked in front of our shop.  We thought it was black initially, but actually it was blue.  Kind of “Power Trip Energy” blue I think.  So proud to be providing clean solar energy to power the car of this unknown person.  Free public solar powered EV charging available at our shop, compliments of Power Trip Energy Corp, so please bring your EV here anytime.

Our most-honored company-founding 23 year old Toyota pick-up is parked under the tracker in the background.

I’m not sure how they found us, but it could have been through chargepoint.com , you should check it out to find your recharging stations when on the road.

SunPower Performance Claims & Our Current Data Analysis Project

SunPower Performance Claims & Our Current Data Analysis Project

Here is an interesting video that actually comes off more as a commercial from SunPower, though it is backed up with third party data.

Here is a more direct link to the third-party support for SunPower’s claims:

http://www.photon.info/photon_news_detail_en.photon?id=75152

We are currently undertaking a comprehensive data analysis from as many of our systems as possible from which we can get clean data.  At this point with our 340 grid-tied pv systems installed, about 20 use SunPower modules, and they appear to be performing very well although our in-house data analysis is not complete.  As we are not a lab, each system has different installation characteristics and is in a slightly different location; our local micro-climates can complicate data comparison.  We are working to integrate our performance data onto maps, and compare all other pertinent attributes such as pitch, azimuth, and shading, before making comparisons between manufacturers.

The main reason we have relatively few SunPower installations although we have been installing them for four years now, is that they are more expensive in terms of dollars per watt (in addition to being more efficient in terms of watts per square foot.)  As we have not yet been able to quantify this, it has been difficult to justify a higher price for the product without feeling like we can make a substantiated claim for additional energy produced per KW.  One of our goals is to see if we can objectively demonstrate more kilowatt hours of energy produced per rated kilowatt of module capacity.  If we can do that, then our performance estimates can reflect that data, and the returns will look more attractive for the SunPower modules thereby easily justifying the additional price when our customers are comparing options.

We hope to have our data analysis completed by the end of August this year and will publish results we feel are rock solid.
