Stop in for a cold, PV-powered beer!

The Butte Brewing Company is located at 465 East Galena Street, Butte, MT (uptown Butte). It is the dream-child of Tony Olsen, who started this project in 2012. The solar array consists of eighty 250W REC Peak Energy Series (REC250PE) solar modules; the silicon ingots are made in Butte, MT and the modules themselves are manufactured in Singapore. The grid-tied inverters are Fronius IG Plus 10.0, ten kilowatt inverters suitable for commercial or larger residential systems.

Tony became infatuated with the idea of a brewery back in 2005; he and a buddy (from the Montana National Guard) visited another brewery in Helena, and he was smitten with the big tanks, equipment and great beer, so he decided that a brewery in a ‘green’ building was his goal. Tony Olsen likes being self-reliant as much as possible, so it was only natural to put a photovoltaic system on his new building—which also includes super-insulated concrete forms and an in-floor radiant heating system. His brewery building also has office space above as well as a large 2500 sq. ft. conference room that is available for rent. The actual building project got underway in 2012, and Tony’s been brewing beer since last fall. The taproom will open officially by June 1st, 2015.

Tony Olsen was able to get Northwestern Energy and REAP grants, and of course the federal tax credit for this project. He says he did get smacked with a significant state tax hit upon completion, but other than that, he’s been extremely happy with his project—and is still thrilled when he sees his electrical meter spinning backwards.

Two years ago the building was still under construction, but as soon as the roof 
was finished, Oasis Montana installed the solar array.

Butte Brewing Company’s goal is to have 20 brews on tap; right now they are brewing the following: honey cream ale, sweet stout, pale ale (with Nelson Sauvin hops), porter, IPA, red ale and hefeweizen. They’ll be officially pouring on or before June 1st!




The solar tax credit is scheduled to end at the end of 2016 for residential and commercial properties…. This is a 30% federal investment tax credit for solar energy systems. It’s a tax policy that has played a vital role in creating good, American jobs, lowering energy bills for consumers, increasing U.S. global competitiveness, energy security, and reducing pollution from fossil-fuel based energy sources. The company or person that installs, develops or pays for the power project uses the credit (a homeowner applies it to his/her income taxes). This Investment Tax Credit (ITC) has been one of the most important federal programs to support the development of solar power in the U.S.; it has driven an amazing job growth sector, with over 20% growth per annum — the fastest employment growth of any industry in our country! The solar industry now employs more than either the steel or coal industries in the U.S.

So if you are considering the purchase of a solar power system, get your equipment together before the end of next year. It would be helpful to also ask your legislators to extend the ITC further, and continue the growth of the solar industries; as time goes on, component efficiencies have increased and costs for consumers continue to go down. Unfortunately, there is no clear consensus among legislators that the expiration date should be extended.

We at Oasis Montana feel that our fledgling solar industry will survive the expiration of the tax credit, if that comes about — but we also feel it is unfair to continue to massively subsidize other energy sectors at the same time! A gradual reduction of the solar tax credit would be a good idea — but only AFTER we cut the more than $4B/year in fossil fuel tax incentives. One would think after 100 years of production the fossil fuel industry would be mature enough and could exist without the tax incentives...especially considering they are the most profitable corporations in the world.

To see what incentives you may qualify for, visit www.dsireusa.org; incentives vary from state to state, and some utilities may offer grants in your particular area.

Arctic grayling struggle on the Big Hole River in Montana: “Montana grayling have been lost from the vast majority of the rivers and streams where they once swam, and they desperately need the protections of the Endangered Species Act to survive,” said Noah Greenwald, endangered species director at the Center for Biological Diversity. “The U.S. Fish and Wildlife's most recent decision to deny the grayling protection is dirty politics that doesn't follow the science. Twenty years is too long to wait for protection.” The Service first determined the grayling warranted endangered status in 1994 and reaffirmed that conclusion in 2010, but reversed course in August 2014 withholding protection from the rare and beautiful relative of trout and salmon. In denying the grayling protection, the agency argued that voluntary efforts by private landowners and the state of Montana, guided by a conservation agreement in place since 2006, have alleviated threats to the fish's survival. Although many individual projects to improve habitat have been completed under the agreement, the grayling continues to face numerous threats, including excessive water withdrawals for irrigation, non-native trout and ongoing habitat degradation. A member of the salmon family, the Arctic grayling is a beautiful fish with a prominent dorsal fin. The species thrives in cold freshwater streams and rivers across Canada and Alaska. Historically, fluvial populations of Arctic grayling existed in only two places in the lower 48 states: Michigan and the upper Missouri River of Montana. Populations in Michigan went extinct by the 1930s, and populations in Montana were restricted to the Big Hole River and a few lakes by the end of the 1970s. Studies demonstrate that Montana grayling are genetically distinct from populations in Canada and Alaska, and have been experiencing severe declines in response to the near drying-up of the Big Hole River on an annual basis caused by increased irrigation use and greater extremes of drought. The following is a story of how ranchers, a solar pumping system, our local FWP and other agencies are trying to protect the last of this unique fish’s Montana habitat.

Whether you need water moved for your creek, your pool, your off-grid home, for irrigation, pond aeration or for your livestock, we can help provide your water pumping solution. Visit us now online at www.PVsolarpumps.com  — fill out the questionnaire and we’ll propose a system for your project. And while we offer several different kinds of pumps, you can view a neat video from one of our suppliers at https://www.youtube.com/watch?v=2HTn0hINh98

WHEN THE POWER GOES OUT….how can I keep my water pump operating in an emergency situation? We’ve been hearing this question on a regular basis. As utility infrastructure ages, and severe weather becomes the new norm, people are concerned about having water available if the power fails. Unfortunately, the answer isn’t always easy or cheap. If your power is pretty dependable and your outages short, your best bet may be a fuel generator; you can have your electrician wire the individual pump circuit or get the properly sized generator to power your entire home, and install a transfer switch. If you are interested in a solar-powered system, it will be considerably more expensive but will feed back power. Most people’s well pumps are AC, which means you need an inverter system that’ll handle the starting surge of that motor, as well as operate the pump for as long as you need water. While many people in the world are very happy to have 5 to 7 gallons per day, the average American uses 50 to 75 gallons per day — and some use much more. Even if your water usage is modest, you will still need to be able to power that pump. For a 3/4HP system:

1 - Outback Flexpower Dual GVFX3648 Inverter system, which includes two inverters, FM80 charge controllers, system monitor and integration equipment, surge protect- tor, battery and PV breakers

16 - Surrette S-480 6V Deep Cycle batteries

24 - Q-Cell 255W 60 cell Solar Modules

2 - 12X Top of Pole Mounting Racks for solar modules

1 - Battery Box vent fan

PLUS the balance of system components including battery cables, hardware, disconnects, combiner enclosures, panel output cables, grounding fittings, surge protectors (but not including installation, shipping or battery box)

Well, folks, we are looking right around $30,000 for just the equipment for a system to be able to run your 3/4 HP water pump. Now in addition to being able to power this pump, when not being used in an emergency situation, this system will feed power back to your utility. Your electricity provider needs to have a net metering plan in place before you can even consider having a system like this (the GVFX inverters are designed to feed power back once the batteries are full in the morning). So you will be able to reduce (or, if you are efficient, negate) your utility bill with this grid-tie system.

Here at the Oasis Montana home/office, we have a system very similar to this, only we are utilizing an Outback Radian inverter and 27 Sanyo solar modules — and yes folks, it did cost upwards of $30K. But, you would still be able to take advantage of the 30% federal tax credit, plus whatever state incentives are available where you live.



We are looking at different 'soft start' technologies that can use a smaller (and hence cheaper) inverter set-up to be able to run a water pump in the absence of AC power. Call or e-mail us for more options.



Hey DIYers — do you know how to handle a solar module? While solar modules are usually made from tempered or hardened glass, and can generally tolerate the same conditions as your car windshield, it’s possible that rough handling can cause ‘micro-fractures’ which can cause degradation of the solar cells many years before its time (solar cell substrates are delicate). If you think about hauling a (basically) framed piece of glass onto a mount structure or a roof, there is evidence to indicate that resting it on your shoulder when you climb a ladder, or leaning heavily on it when you are attaching it to the mounting racks can indeed have a long-term effect on its longevity and performance. So whether you are a solar professional or a do-it-yourselfer installing your own solar modules for your home or business, get another person on the other end of the frame, and handle it with care. Make sure your mounting structures are rated for and give adequate support in high winds or under extreme snow loads — which can also cause micro-fractures. Ultimately, too, not all solar modules are created equal. Some of the cheap deals can have thinner glass & frames, or be of poorer construction which can contribute to a shorter electrical lifespan.

If a solar panel has been dropped or stepped on, it may appear to be fine and still operate at full output. But it has likely suffered from micro-fractures which will ultimately result in reduced output. We rate the useful lifespan of a solar module at 30 to 40 years (and most we sell have a 20 to 25 year output warranty). Still, they should be installed carefully to get the most bang for your bucks—and good longevity. Here’s a video about micro-fractures, and how NOT to clean your solar modules:

Something new is blowing in the wind….our popular 200W CHINOOK Wind Turbines were discontinued a while back, but a redesigned model is in the works, and we are hoping it will be available by the beginning of next year (2016). The new beast will be a 500W model, and will be available as a 12, 24 or 48V battery charging unit—or for a grid-tie system with no batteries. The Chinook folks are in corroboration with Midnite Solar, so the new wind genny will undoubtedly come with its own controller (if as a battery charging model) or a grid-tie inverter will be specified if you don’t want to mess with batteries.

Another wind turbine from Midnite is in the works, the ARMY WIND generator; it’s a one kilowatt model (1000 watts top end); it’ll be tough as nails and will also be available for 12, 24, 48V battery charging or as a grid-tie unit. We really don’t have much information for these at this point; they are in the testing phase. As soon as these become available we will be offering them. Stay tuned for more information!

Crystal Ball Gazing

We get calls asking about trends in our industry. Based on our “insider” knowledge and sources, we would like to share some of the trends we see as having an impact plus some of the, at present, “pie in the sky” notions you may have heard of or are wondering about.

Energy Storage (batteries):

All batteries are a form of storing energy and the primary focus of late has been on enhancing “energy density”. FLA (Flooded lead acid), AGM (Absorbed Glass Mat) and Gel cell batteries are the most commonly used batteries for storing energy generated by alternative energies and represent the best investment today. A major focus of the renewable energy industry now is energy storage; here are a few of the leading contenders for alternative energy storage devices.

LiOn (Lithium Ion) batteries are becoming more main stream with the advent of Electric Vehicles. Though progress has been made in creating a safer (less prone to melt down) battery, there remains room for improvement. These have proven very reliable and are an effective means of storing energy for use in our phone and tablet devices, but their charging perimeters for power systems are very specific and there are still bugs to be worked out for integration into RE power systems.

Li-air (Lithium Air) much of the current research is focused on four different chemical designs. The aprotic design is see the most focus at present. The other three design technologies; aqueous, mixed aqueous/aprotic and solid state all face distinct advantages and significant technical challenges.

There has been a lot of money invested in coming up with an innovative energy storage device and we suspect there will be more in the near future. Our “Crystal Ball” gazing reveals that the next evolution will come from tinkerers working from a garage somewhere. They typically will have as a goal some personal desire to improve an aspect of their own lives and a new application of existing technology will likely create the next major boost in development.

KAir (Potassium Air) in Oct 2014 Ohio State University announced the introduction of a potassium air battery that achieves 98% energy efficiency. We’ll have to wait and see if this product comes to market.

NiFe (Nickel-iron) nickel-iron batteries are also known as “Edison Battery” and have an extended life extending well beyond the rated 20 year life. The slow charge rate coupled with slow discharge rate make them an undesirable solution for all but a limited number of applications for renewable energies.





Unlike AC fans, these well-made Solaro Aire™ units won’t use a penny of your electricity. During summer months, your attic can get up to 160°F, making your home miserably hot. Solaro Aire™ fans extract the heat from your attic, keeping temperatures and air conditioning bills down. These fans run ‘array direct’; when the sun shines, they are running, and during the hottest part of the day is when they are moving the most air. These are a terrific replacement for noisy turbine-type vents.

SA-20WT-LPEThe SA-20WT-LPE, left, has a 20W solar module and moves up to 950 CFM., with an polymer fan blade and brushless motor; its cost before shipping is $820. The model, right, SA-20WB-LPE is a low profile style fan, great for composite and shingle roofs ($743 before shipping). At lower left is the SA-20WR-LPE, which offers a model where the solar module can be mounted remotely (if the sun access in the desired fan location is in the shade). This model is $799 before shipping; you can also get a larger solar module if needed, in case you have shading issues where the fan is placed. Higher profile fans are available where additional     clearances (SA-20WT-LPE, above)  are needed; gable mounted fans for ventilation are also available. Factory
installed thermostats are available ($59), so the fans will only operate when the temperature  is above  (SA-20WB-LPE, above) 85°F. These fans can also be used in winter months to remove mold and mildew-causing moisture.

We can send you installation links for these fans, something your contractor or handyperson can do. And these also qualify for the 30% solar tax credit through 2020 (cost of the fan plus installation). These come with a limited lifetime warranty from the manufacturer; and built with aircraft aluminum specs, they are meant to last a lifetime, with weather resistant powder coated housing providing a durable finish. If you are interested in these fine fans, send us an e-mail today and we will send additional information. info@oasismontana.com


   (SA-20WR-LPE, above)




You can become an energy detective with your Killawatt™ Meter!

If you are trying to keep a lid on your electric bill, it’s most helpful to determine what your electrical loads are on certain devices. Is your refrigerator really an energy hog? How much more juice does your PC use than your laptop? This device is a simple way to determine your electrical usage. You plug it into a wall socket (or perhaps onto an extension cord, to make it easier to read) and plug your appliance or device into it. It will give you instantaneous readings on voltage, watts, amps, and frequency (hertz) numbers. It also gives you cumulative data—so you can see how much power your ‘fridge pulls in a week. If you plug your refrigerator into it, it should cycle and give a higher figure from time to time—that means your compressor is running then. These are still a great deal at $25 plus shipping!




States That Produce Renewable Energy Have Cheaper Electricity: http://www.onearth.org/earthwire/renewable-energy-prices A study released by the venture capitalist firm DBL Investors shows that states boasting robust green energy programs have the nation’s cheapest electricity. The trend lines suggest it’s only going to get better for their consumers. In 2001, electricity cost more in the 10 top renewable energy states than it did in the 10 states with the lowest proportion of green energy production. By 2013, the situation had turned upside down: States with the most green energy now offer cheap electricity, while the dirty power states are the most expensive. The 10 states with cheap green energy are Maine, Iowa, South Dakota, California, Idaho, Kansas, Minnesota, North Dakota, and Oklahoma, plus Washington, DC. The 10 laggard states in the DBL study were Florida, Connecticut, Delaware, South Carolina, West Virginia, Rhode Island, Ohio, Missouri, Tennessee, and Kentucky.

New Tesla Battery Will Power a Home and Maybe the Electric Grid Too: http://www.washingtonpost.com/blogs/the-switch/wp/2015/02/12/this-new-tesla-battery-will-power-your-home-and-maybe-the-electric-grid-too. Tesla is working on a battery that can power a home and even help large-scale utilities store energy more efficiently, according to company chief executive Elon Musk. If Tesla's stationary battery takes off, it could change the way electricity is priced and traded on a market scale. Musk said the designs for a home or business battery are already complete and will likely be unveiled to the public "in the next month or two." Production could be as little as six months away, he added. "We are trying to figure out what would be a cool stationary (battery) pack," Musk said. "Some will be like the Model S pack: something flat, 5 inches off the wall, wall-mounted, with a beautiful cover, an integrated bi-directional inverter, and plug and play." There's no word yet on price.

Solar PV Will Be Cheapest Form of Power Within a Decade: http://cleantechnica.com/2015/02/25/solar-pv-will-cheapest-form-power-within-decade/? A major new study from a leading German think tank and renewable energy specialist says the cost reduction potential of large scale solar is still misunderstood, and predicts that solar PV will be the cheapest form of power within a decade, and cost less than $0.02/kWh by 2050. The study by the Berlin-based Agora Energiewende says that the end to cost reductions from solar plants is “not in sight”, even after falling more than 70 per cent in recent years. The balance of systems costs are expected to fall by up to 2/3 in coming decades, and combined with a fall in the cost of finance, could cut the cost of solar technology in areas such as the U.S., Australia, and parts of Europe.

Greetings from our solar powered office!

In the event of a lengthy power outage, what are your critical loads?

With the presence of winter storms, hurricanes, tornados and aging grid infrastructure as part of daily life, many people are rethinking how reliable utility power really is, and we are getting more calls for back-up power for certain loads. Some of our customers just need to have power for charging their cell phones, Kindles, tablets or similar devices (and a couple of lights or a small TV for an hour or so); a small system for them might entail the following components:

System #1, small system: One ~300W solar module, 300W sine wave inverter, charge controller, 12V 55AH AGM battery, combiner enclosure with fuse, flush roof rack, panel output cable; $1449

Other folks are concerned about losing their food if the grid goes down, so they’ll want to power their refrigerator and perhaps a freezer too. If your appliances are of more recent vintage, backing them up will cost much less than if they are older, less efficient models. An efficient refrigerator shouldn’t use much more than a kilowatthour a day, and a freezer might be in the ~1.5KWH range (but contact the manufacturer to be certain). A system to power those loads, plus a couple of lights, might entail these components:

System #2, medium system: (MS2812 Magnum inverter, 6 ~300W solar modules, 6X top of pole mount, Classic 200 MPPT charge controller, 4 L16 type batteries + cabling, battery monitor, interconnects, combiners and disconnects; $8700

If you don’t have city water, a common concern is powering your well pump. One can live without a lot of things but water is not one of them! And many deep well pumps are 240VAC; if you needed a backup power system to run your ½ HP 240VAC pump, say, one hour a day, plus extra power for a fridge and small loads, you might be looking at a system of this size:

System #3, large system: (Radian GS4048 – loaded, on a pre-wired power center that includes the charge controller, MATE3 system monitor, disconnects, etc., 12 – ~300W solar modules, 16 – L16 type batteries, pole mount, battery cabling = $14750

Costs do not include freight, installation, concrete footer for pole mounts, ground rod & clamp, and miscellaneous electrical widgets or wire runs.


Some people think solar modules are ugly – but I think they’re beautiful…and how wonderful it is to get electricity from sunlight!
And, you can enjoy saving money while saving the planet.


Are you looking at a stock watering project this year? Or you want power for a pump if the utility fails? Or perhaps you have a pond to fill, or fruit trees that need irrigating? A remote cabin? Contact us for all your remote water pumping needs; visit www.PVsolarpumps.com for more information.

If your only concern if the power goes out is water and you have a, say, 1.5 HP 240VAC pump, we can now run many of those pumps array direct whenever the sun is shining. So if you need water for irrigation or stock, this new PicoCell system might be just what you need. The PicoCell, from SunTech Drives, is now part of our line of quality solar products, and we look forward to the next generation of their solar evolution as the newer and more robust water pump solutions come on board. Being powerless doesn’t mean being waterless any more! Depending on your water pump make and model, we may have a solution for those times when the power is gone but the need for water exists and the sun is shining. Three-phase water pumps and motors under 2HP manufactured by Berkley, Franklin, Flint, Goulds, Grundfos, Myers and Wailing are all great candidates for using the new PicoCell from SunTech Drive to run your water pump while the sun is shining and conventional power is out. Single phase pumps up to 1HP from these same manufacturers, including Sta-Rite are able to operate effectively also. Call for more information or to see if your pump will work with a PicoCell. 406-777-4321

Cows LOVE solar water pumping!


We offer the Grundfos, SunRotor, Dankoff and Lorentz pump line, from submersible to surface pumps. And we can power your 240VAC pump too! 406-777-4321 for tech support on pump systems.


TAX SEASON is nearly upon us! If you had a solar power system installed and running by 31st December, 2017, you are eligible for a 30% tax credit of the cost of your solar module installation, less any state incentives or rebates. The 30% tax credit is still available through the end of 2019, so now the time is ripe for investment in the solar power system of your dreams. It is also available for certain types of solar thermal (hot water and space heating) systems. https://www.energystar.gov/about/federal_tax_credits/solar_energy_systems for the links about the federal tax credit; http://www.dsireusa.org for a state-by-state database of all renewable incentives; and https://www.irs.gov/pub/irs-pdf/f5695.pdf for the personal tax credit form.

MNChinook 200 Wind Turbine Now Officially Available http://files.constantcontact.com/aaa32e00401/5cc9c46b-fd24-4c58-8538-64e359dee783.jpg
The Chinook 200 is now new and improved, a direct-drive micro-turbine designed for use in 12, 24 or 48 volt DC battery charging applications. Its attractive low-profile design, exceptional performance in low winds and low rotor acoustics, make this turbine the ideal choice for almost any application. It’s also very quiet, and mounts on a 1.5” Schedule 40 steel pipe.

The Chinook 200 can also work hand-in-hand with PV panels to ensure that power is being generated in all weather conditions; they can be charging the same battery bank, and are also suitable for marine use. The MidNite Chinook Diversion Load (CDL) is an integrated solution designed to prevent 12, 24 or 48 volt batteries from overcharging and is included with the Chinook 200. Compact and easy to install, the CDL incorporates a 300 Watt resistive heating element and controller board in a powder coated steel enclosure. $995 plus shipping includes its dump load controller. The output voltage is not field selectable and must be ordered for either 12V, 24V or 48V battery charging. Designed in Montana and still made in the USA, if you have good average wind speeds (10-12 mph+) you will find this to be an excellent addition to your battery charging scheme.
