SBS Solar Customer Testimonial for MT Audubon

Thursday, April 12th, 2012

What follows is a great Q&A with a recent install for Bert Lindler and Kristi DuBois:

1.  Why did you decide to install solar panels?

When we first bought our home, we realized that the south-facing roof offered an opportunity for solar photovoltaic panels and solar hot water.  We want to minimize our environmental impact and installing solar panels is one of the easiest ways to do so.

Kristi feels strongly that every south-facing roof is wasted space that should be generating electricity.  Industrial forms of “green” energy like commercial wind and solar farms impact a lot of habitat for wildlife, or in the case of solar farms, replace the habitat completely with solar panels.  Rooftop solar units have no effect on natural habitat, so they are a much greener way to meet our energy needs than industrial energy facilities.

We were considering refinancing our home to take advantage of low-interest rates at about the time we were reminded of the subsidies available for installing solar photovoltaic panels.  Once we had the roof evaluated for solar power potential and had received a bid for the installation (along with an estimate of the subsidies), we knew we wanted panels.

2.  Did you encounter any challenges during the installation process?

The first challenge for us was approval from the homeowners association for our installation. Our installer prepared drawings showing the appearance of the eight panels mounted on our roof. We took to the drawings to our immediate neighbors and discussed our plans. All but one of the neighbors were supportive and the remaining neighbor said that while he didn’t want to look at solar panels on our roof, he understood why we wished to install them and would respect whatever decision the homeowners association reached. The association’s architectural review board approved our request.

The next challenge was a couple of tall non-native trees growing in our yard. We were considering having them removed anyway, but did so promptly after we learned that they would shade the panels. We still have some shading in winter from our aspen trees, but the effects on our power production are minimal. We left the trunk of one of the trees standing as a wildlife snag.

3. How long will it take for your system to pay for itself?

If the price of electricity stays in the range of 10 cents per kilowatt-hour and our photovoltaic system produces 2,289 kilowatt-hours of electricity each year as estimated, the system should pay for our cost of installation in 15 years (the system has a 25-year warranty).  If the price of electricity goes up, the recovery period may be much shorter. If the price of electricity goes down, we may never recover the cost of installation.

Our cost was much less than the system’s total cost of $12,629. We received a subsidy of $6,000 from Northwestern Energy for our 2-kilowatt installation and federal (almost S2,000) and state income tax refunds ($1,000).

Our system includes microinverters that  convert the DC electricity produced at each panel to AC electricity we can use in our home or return to the grid for use by other Northwestern Energy customers. The microinverters reduce the risk that more than one panel will be affected by shading and are provide real-time monitoring of the power being produced by each panel.

Our account is credited if we produce more electricity than we use (only likely during the summer). This arrangement allows us to receive full benefit of all the power we produce without requiring us to buy a bank of batteries to store power.

We do expect that our home will be easier to sell and may command a higher price because of the panels.

4.  How do you see your solar panels contributing/fitting into the larger Missoula effort against climate change?

Our purchase reflects our personal values, greatly influenced by subsidies offered by the power company and federal and state governments. Even though Missoula’s solar energy potential is not as high as in areas with more sun, our community could reduce our environmental impact if more of us took advantage of the subsidies that turn roofs into power plants.

What sort of lessons has the process of installing your own solar panels taught you?

Snow melts quickly off our south-facing roof. We had expected the snow to melt just as quickly off the panels. It doesn’t. The panels, mounted an inch or so above the roof, have cold air beneath them.

We use a pole-mounted plastic snow rake to clear snow from the panels and onto our deck.  The deck never used to get shoveled, but it does now.

In general, we were extremely lucky. The cost of solar panels has dropped dramatically in recent years and the cost is still dropping. The installer handled the $6,000 reimbursement from Northwestern Energy so we didn’t have to pay that cost up front. The remaining up-front costs weren’t a problem because we refinanced our home loan when interest rates were at record lows.

The panels were installed on schedule at the agreed-upon cost.  Within a week after our panels were operating, Northwestern Energy installed the special meter that gives us credit for the electricity we produce.

During December, our solar panels produced just 18 percent of the electricity we used, but as the days became longer, the panels produced 30 percent of the electricity we used during January and 43 percent during February.

We enjoy having the panels and we’re happy to see them producing more electricity as the days keep getting longer.

Green Blocks – Final Phase

Tuesday, July 12th, 2011

SBS has had a wonderful and successful time on the side-order list for the City of Missoula’s Green Blocks energy saving program.

We began work back in the Fall of 2010 by getting 2-inters from the University of Montana’s COT Energy Program and got them fully trained on doing a basic solar site assessment.

Our Team ended up doing over 120 assessments over the course of 3-months last fall.  They braved blazing sun, side-ways rain and blowing snow from October – December.  But, it was well worth it.

This spring 2011 marked the final phase of this project.  The City added about 60-90 participants to get to their total count of 300.  We got ourselves another COT Energy intern for this past Spring and he went out and did about 48 more solar site assessments.

Half way through this phase we saw an 18% REDUCTION in the cost to install solar, plus the state and feds decided to KEEP the tax credits in place for renewable, Northwestern Energy gave us a dozen more $6k grants to hand out to customers in good standing, and the MT DEQ revolving loan fund keeps on chugging along (although they are 8-10 weeks out on funding).  To top it off, SBS starting taking credit cards for deposits.

The wet cold spring made for a slow start, and with the unseasonably cool summer, folks were not thinking about solar.  But with the aforementioned incentives, and a little 90 degree weather, we are in full swing.  Over half of the installs we’re doing in July and August came from Green Blocks leads and SBS is now booked out until September.

Thanks to the City of Missoula for this great opportunity!  We’d love to do it again.

SBS Summer Reading Heating Up: Solar? Conservation? Efficiency

Monday, July 11th, 2011

While there certainly has been a lot of talk lately about the weather, and whether global warming is real or not, the concept of climate change is certainly on our minds (or should be).  It seems that catastrophic weather events are more prevalent than ever: from tornadoes to floods to tsunamis, earthquakes, mudslides and volcanic eruptions.

In response to these major weather events, and in an effort to gain some knowledge, I have been doing some summer reading.

First on the list is a behemoth of a book – and worth the hundreds of pages – Hot, Flat and Crowded by Thomas Friedman. Simply put: We are getting hotter as a globe from fossil fuel energy dependence.  We are getting flatter as a world through wireless technology.  We are getting more crowded as a world through population growth. This book points out, more than ever, the mounting global energy crisis with the advent of a larger-than-life working-class in major cities around the world,  namely China and India.  It also details some very viable ways we could remedy the current situation and prevent total global melt-down – like applying the idea of a smart grid to our utility use and billing, efficiency and renewable now (not later), government mandates and crackdown for laziness in getting on board, and even suggesting that the USA needs to getting into a race w/ China to “out green” one another – akin to the space race with former USSR that put a man on the moon in short order.

Another great read, and a bit shorter, is an  article in Rolling Stones:  “Al Gore: Climate of Denial: Can science and the truth withstand the merchants of poison?“  This article addresses the question of whether we are all in denial about climate change or not.  Former Vice-President Al Gore emphatically says “Yes, we are in denial.”  The final paragraph states:

The climate crisis, in reality, is a struggle for the soul of America. It is about whether or not we are still capable — given the ill health of our democracy and the current dominance of wealth over reason — of perceiving important and complex realities clearly enough to promote and protect the sustainable well-being of the many. What hangs in the balance is the future of civilization as we know it.

And finally, the shortest of all the reads, an article from Newsweek: “It’s still the Economy, Stupid. 14 Ways to put America back to Work” by 42nd President Bill Clinton. In June 2011 in Chicago, the Clinton Global Initiative (CGI) focused on America for the first time, inviting business and political leaders to make specific commitments in support of the former president’s jobs blueprint, which he details in this article. Here Clinton outlines his plans for economic stimulation.  Interestingly enough, the first half circled around energy efficiency and the funding there of.  Namely, #2 Cash for Startups, #3 Jobs Galore in Energy, #4 Copy the Empire State Building, #5 Get the Utilities in on the Action, #6 State-by-State Solutions, and #8 Paint ‘Em White.  And, really, all fourteen talk about energy conservation relating to economic stimulus in one way or another.

So sit back, try to relax and enjoy the reading.  (Then change out all your light bulbs to CFLs and LEDs, install a solar array and fix that leaky faucet.)

SBS Intalls Solar for Ravalli Co Habitat for Humanity

Thursday, June 16th, 2011

According to the Bitterroot Star, last week the the fifth home by Ravalli County Habitat for Humanity was completed and keys handed over to the owners. The new home is on Cherry Street in Hamilton and now belongs to Travis Sanderson and his family.

Much of the materials for the home were donating, including a Solar PV system – made possible through the work of Sustainable Building Systems (SBS) and Northwestern Energy’s Solar PV grant.  This system will reduce the family’s prior heating bill of $350/month in winter to around $80/month.

Solar Prices drop up to 25%!

Thursday, June 2nd, 2011

After a PV module industry wide cost reduction, sourcing a lower cost mount system and dealers giving better pricing on all balance of system components, SBS has new numbers for potential Solar PV customers in MT that represent up to a 25% reduction in installed costs for PV systems!

If you couple the new lower prices with a $6000 Northwestern Energy PV grant, the 30% Federal Tax credit for renewable energy and the $500/$1000 (single/couple) State Tax credit, the costs are lower than every before.

And here in Montana, we can add to that a 10-year, 4% financing option (oac) from the MT DEQ revolving loan fund for renewable energy.

For a 2kw, 9 module system, total cost to the customer is in the $12,000.00 range.

After incentives this is roughly 3,200.00 out of pocket.

This on average powers about 25-40% of the average Montana home.

Here is an example of plausible breakdown for that $12,000 system

$12,000 GROSS
- $1000 (deposit to SBS to begin work)
=$11,000 NET
-$6,000 (NWenergy PV grant)
=$5,000 – Financed w/ MT DEQ loan
120-months
4%
=$51/month

Yes, that is correct, for at little at $51/month for a 10-year period, you can cover up to 40% of your energy bill. Awesome.  Check out this PV for more information: SolarPVFinancing-Basics-final.

And, when you file your taxes at the end of the year on that system, you’ll still get the $1800 Federal credit and the $500/$1000 state credit back.  You can keep these to use however you’d like, or put that money into your DEQ loan for early pay off (there is not penalty for early pay).

The Northwestern Energy Solar PV Grant

Wednesday, March 23rd, 2011

As a company with a NABCEP Certified Solar Installer, we are one a few companies in the state that qualifies for special $6,000 grants from Northwestern Energy for Solar PV installs. We’ve been granted access to 11 such grants and have already allocated a few of them.  Our goal it to have them all in install mode by Halloween.  If you have been considering Solar PV, this sort of assistance really starts to make it affordable, especially coupled with State and Federal Tax Credits.

Consider that the average US home uses 9000 kWh (kilowatt hours) of power per year.  This is roughly 26.5 kWh per day. For example’s sake, we’ll say 25 kWh, which would be easy to obtain with minor energy retrofits).  If you figure that we have, on a annual average in Western Montana, 5-hours of sun per day to make energy from, that would mean we’d need to produce 5 kW of energy from that system, per hour, to get to 25 kWh.
5 kW x 5 h = 25 kWh

Now consider that the average panel produces 185 W.  This would mean the 5.5 panels would be needed to produce 1 kW.
185 W x 5.5 panels = 1000 W
1000 W = 1 kW = 5.5 panels

So, to get to the 5 kW system we’re looking for, the average system would require 27 panels.
5.5 panels = 1 kW
27 panels = 5 kW

Now, most folks are not interested in offsetting 100% of their energy quite yet.  Here in Missoula we have annual net metering.  This means that you are assessed a bill each month depending on how much energy your system will put back in the grid (i.e. in January that might only be 10% and in July it could be 120%).  At the end of the year your total usage and production are assessed.  If you produced a deficit of energy, you will already have paid that amount through your monthly billing.  If you produced a surplus, well, you’re neighbor thanks you for putting clean, solar energy back into the grid.  But, at this point, Northwestern Energy doesn’t pay you back.  That’s not to say they won’t someday, with energy rates increasing at 4.4% on average.   However, since they currently do not pay you for your surplus, we usually design and install systems that cover 90% or less of your annual energy needs.

So, back to the example above.  Take the 5 kW system.  Let’s say we only want to go with 75% coverage.  We’re now at 3.75 kW (or 3750 watt system).  At an average rate of $5-$8, per watt, installed, we’ll use $6 in this example.
3750 W x $6/W = $22,500

Now, apply the $6000 Northwestern Energy Solar PV Grant, 30% Federal Tax credit, and $500 per MT tax payer credit (so, $1000 for most households):

$22,500 (gross)
- $6,000 (NW Energy)
- $4,950 (30% Federal Tax Credit)
- $1,000 ($500/person MT Tax Credit)
_____________
=$10,550 (net)

This is, of course, just an example.  But is a good indicator of what’s out there today.  If you don’t have tax liability this year, the tax credits can be carried forward for up to 5 years.  There are also other incentives and tax deductions out there, as well as some forms of revolving loan financing that can be applied to either the net or gross amount.

Solar Highways – The Horizon is Near

Tuesday, October 19th, 2010

Now this is something I am excited about. My mom sent me the link to this video over the weekend and she is right on. Solar Highways. If we were able to construct a save road, parking lot, highway materials w/ photovoltaics under super strong glass we could harness enough energy to cover ALL USA ENERGY NEEDS PLUS 15%!!!

Let that resonate for a moment.

No oil based electricity.

No coal powered electricity.

All solar. ALL SOLAR.

They even go on to explain how post consumer waste, otherwise headed for landfills, would be the source, mixed with other organic materials, to form the base and structure for the panels.

And finally, from a safety perspective, they plan to include embedded LED lights, powered by the solar, that would be used for a myriad of reason like lighting up crosswalks, giving messages like “SLOW DOWN, CONSTRUCTION AHEAD,” changes in speed limit, etc…

Watch the entire video here.

As I was noodling around in related news, I came across another neat happening in the past year. The State of Oregon is putting together some of the first highway solar projects along the highway like the arrays along the autobahn in Germany.

You can view that video here.

SBS Teams up with “Cool Green Home”

Wednesday, August 18th, 2010

The Montana Radio Company and Sustainable Building System’s have teamed up to bring Cool Green Home to Missoula, where over $135,000 in home renovations will be given to a few lucky Missoula homeowners.

The project was started with a simple idea, take an existing Missoula home and create a “showcase” for energy-efficient and sustainable products offered by local businesses.  It has gained so much attraction that 24 area businesses have partnered with us on this unprecedented project, and each will contribute in their area of expertise.

Our goal is to show our community that sustainable and green homes are not only good for our planet but good for our bank accounts, and with planning, big improvements can be made with modest steps.  We intend on setting an example as to what a sustainable green home could look like.  We don’t intend on building one from ground level but getting an existing home started on the path to green. We will start the home remodel by completing an energy audit of the home to identify the best places to improve the energy efficiency.  For the next year we will continue to monitor the Cool Green Home and track how much money the family saved in energy costs and how their lives improved.

We received over 180 applications from Missoula-area homeowners and paired them down to a set of 10.  From here the winners were chosen.  Congratulations to our winning homes:

  • Elke Govertsen & Paul Donaldson
  • Jana & Chuck Doyle
  • Ross & Norma Nickerson
  • James Dodge & Jenny Daniel
  • Paula Raines & Michael Hoffer

Keep checking here and at www.CoolGreenHomeMissoula.com for updates and information on the progression at these five homes.  And if you entered and were not a winner, do not fret, there are great tips and DIY projects associated with this year’s projects and we’re already looking to 2011 for another round.
