Latest projects with AC SOLAR MODULES by BenQ Solar!  We are happy to be able to offer the latest revolutionary power technology —  these solar modules manufactured by BenQ Solar combine its premium PV module with reliable microinverter technology, maximizing PV (photovoltaic) benefits for end users.  The integrated microinverter converts the module’s DC electricity to grid-compliant 240VAC at each module, increasing system performance by up to 25%, reducing shading losses and making solar power safer to install and own. 

 In terms of a straight, batteryless, grid-tied system, there are several advantages of an AC solar module, namely:

Harvests 5-25% more energy than traditional systems Simplified PV system reduces installation costs. No high-voltage DC means safer installation and ownership. Superior performance under weak light or shading conditions Three-busbar design enhances current transmission and module reliability.

Like most solar modules, these also offer a 25 year output warranty (10 year warranty for material and workmanship, guaranteed output of 90% for 10 years and 80% for 25 years). Additional specifications are as follows:

Here are a dozen BenQ 225W AC solar modules on a residential system just south of Hamilton, MT.  Thanks, Mick, for your clean energy investment!

Going solar has never cost less or afforded more options!  Whether you want to lessen or negate your utility bill, live off-grid or have back-up power in the event of a utility outage, it’s easier than ever to have your own power system.  The 30% federal tax credit for these systems will expire at the end of 2016, so be planning now for your future hedge against utility inflation.  You can view what incentives may be available for the state you live in at www.dsireusa.org; this site is updated monthly with the latest information.  Here are some facts about solar power in the U.S. for 2013:

  • The U.S. installed 4,651 MW of solar PV in 2013, up 41% over 2012 and nearly 15 times the amount installed in 2008.

  • There were 140,000 individual solar installations in the U.S. in 2013 and a total of over 440,000 systems are operating today.

  • More solar power systems have been installed in the past 18 months in the U.S. than the previous 30 years prior!

  • The market value of all PV installations completed in 2013 was $13.7 billion USD.

  • Solar electricity accounted for 29% of all new electricity generation capacity in 2013, up from 10% in 2012.  This made solar the second-largest source of new generating capacity behind natural gas.

  • Average commercial PV system prices fell 15% in 2013, reaching a new low of $2.59 per watt in the fourth quarter.




Weather:  While Australia was burning up and California was drying out, Montana (and much of the rest of the country) experienced one heck of a winter. Potholes aside, we’re not complaining; we are at 150% or better of snowpack here, so we hopefully look forward to a summer free of forest fires. Still, it’s hard on the critters. Two years ago, with my batch of mail order chicks (and a “free” rooster), I received a very personable Andalusian rooster. Unfortunately he’s a warm weather bird, native to the deserts of Spain; 100°F is not too hot for him, but zero is mighty cold.  None of my hens had problems with the cold, but as you can see, his comb suffered frostbite, despite the heat lamps that forced me to buy utility power for the first time in a year! He is recovering thanks to a combined application of Vaseline, Bag Balm and antibiotic ointment. But it WAS a rough winter!


SWAPPING WIND TURBINES from a 24V to a 48V model

The old wind genny is down, the new one is up!  We finally got around to taking down our old 24V wind generator and putting up the new 48V Chinook (that’s Chris Daum on the ladder at the home/office of Oasis Montana).

First, we disconnected the positive and negative leads from the battery bank, then we disassembled the box at the base of the tower that housed the wind turbine’s wiring, controller and surge protector. 

The job then entailed attaching a ladder to our ~30 ft. log pole, and removing the bolts at the top that secure the 1.5” schedule 40 steel pipe to the log (pictures to the left and center, above); then we removed bolts at the bottom (the steel pipe is still attached in the middle with a swivel connection).  We attached a rope to the bottom and lowered the old turbine carefully; quite the feat considering it weighs in at about 50 lbs.  And by ‘we’ I mean myself and my husband, Ace.  Once the turbine was down, we removed the connecting fittings from the steel pole (far left).  We needed to have a new coupler made to fit the new turbine (our thanks to friend Tony Swallow for his machining skills) so we could mount it on the old steel pole. 

Then we were able to attach the new wind generator and pull it erect, repositioning the bolts at the top and bottom of the pipe.

While the Bitterroot Valley is not the most ideal site for wind generation, we do get significant winds in winter and spring, and during the dark days of winter (or with snow on the solar modules!), a good time of year to have additional battery charging.

The old wind turbine’s maximum output was right around ~300W, and the new one’s top end is around ~200W, but since it is designed to activate in lower winds, I feel it will still be a valuable addition to my power system. 

Rumor has it that those sharp folks at Midnight Solar are working on their own residential wind generator, being beta tested right now.  Stay tuned for additional information!




Call for availability, freight costs, and quantities (# of modules) on pallets for the best deal. You can’t get less than a pallet quantity to get the pallet ‘deal.’ For larger modules, pallet quantity generally runs between 20 and 56 modules, and often there are significant additional charges for less (or more) than even pallet quantities. Some suppliers charge re-boxing fees, too.

NEW Grid-tie Inverter from SMA is smart enough to provide daytime power in the event of a power outage!  Unlike most grid-tie batteryless inverters, which shut down in the event of a power failure, SMA’s new Sunny Boy TL-US SPS (secure power supply) models offer up to 1500W of power during daylight hours while the sun is shining — enough to power any loads that do not exceed 1500 watts total.


These new SMA inverters are transformerless, so owners and installers benefit from lower weight and higher efficiencies. The wider input voltage range also means the inverters will produce larger amounts of power under a variety of conditions. Also, transformerless inverters have been shown to be among the safest string inverters available. An operating temperature range of  -40°F to +140°F assures power production in all climates and for longer periods of times than most string inverters.

The new TL-US residential line features more than high performance and a large graphic display; the monitoring and control options provide users with a great degree of flexibility.  Through a wireless communication standard (that is often used for home energy management) and numerous wired options, monitoring on SMA’s Sunny Portal can be accomplished from anywhere on the planet with an internet connection.  Installers and customers can find the best solution to their monitoring needs, and will know what their system is doing at any time.

See our new webpage (http://www.grid-tie.com/SMAsmart.html) for pricing and specs on these new inverters.  Prices do not include shippingcall for your pricing.

Blueprint for 100% renewables by mid-century
The clean energy sector offers several scenarios that suggest 100% of our energy needs can be met with renewables by 2050. While the implementation of this possibility is more difficult that the report suggests, these models can serve as an important exercise in imagining and planning for what is possible. 

Stanford Professor Mark Jacobson recently released new calculations that conclude that, by 2050, onshore and offshore wind, utility-scale and rooftop PV, concentrated solar power (CSP), geothermal, wave, tidal and conventional hydropower can meet 100% of U.S. energy demand.  “Every new power plant should be a clean renewables plant,” Jacobson said. “If every new car sold today was an EV, in fifteen years almost every car would be electric.”  Jacobson’s plan eliminates nuclear energy because of its energy intensity and time horizons. According to Jacobson's analysis, the fossil fuels used in mining and uranium refining are nine to 25 times the amount used by wind  energy  per unit energy produced. For  more information  on these  interesting ideas, visit

Renewable Energy News Bites:
Complacency Could Lead to Fukushima-Like Nuclear Catastrophe Anywhere, including the U.S.:
Union of Concerned Scientists, February 11, 2014, http://www.ucsusa.org/news/press_release/ucs-book-on-fukushima.html. A new book, " Fukushima: The Story of a Nuclear Disaster" concludes that the NRC hasn’t learned the lessons of Fukushima and has been slow to implement even the few regulatory changes it has decided to require. It warns that if NRC commissioners insist on watering down the agency post-Fukushima task force’s recommendations for strengthening safeguards, it will only be a matter of time before a similar event happens here because U.S. nuclear plants are vulnerable to catastrophic natural disasters, multiple system failures, and terrorist attacks; and U.S. nuclear plants are not much better equipped than Japanese plants to cope with severe accidents.

Meanwhile, over the same time frame wind grew 309% to 140.8 million MW-hrs and solar grew 607% to 4.3 million MW-hrs. That doesn't include distributed solar on residential rooftops or any installations from 2013, which was a record year for solar, installing about 4.4 GW in the U.S. The driver of coal's declining role in electricity and the growth in renewable energy -- particularly solar -- is economics. For example, a utility scale solar project with a 10% return on investment would create electricity for 9.3 to 11.7 cents per kW-hr without subsidy.

Thank you for your interest in Oasis Montana.  For more information go to http://www.oasismontana.com/, send us an email at info@oasismontana.com, or call us at 406-777-4321or 4309.  And feel free to share this newsletter with your friends; knowledge is POWER!


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
For additional information on smallish, RV-type systems, visit http://www.oasismontana.com/RV_systems.html.

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.

The manufacturers of the Diamond propane gas refrigerators are now offering a non-CSA certified offering available as a refrigerator/freezer unit in 19 cu.ft. and 21 cu.ft. capacities. While this means we cannot ship these to Canada, their cooling performance is not compromised in any fashion – in fact these have the same identical cooling unit as those installed in the Diamond gas fridges of the same size. These are some of the finest performing gas absorption units in the industry. Both sizes will be offered in the popular white, black and also stainless steel finishes, and they are less costly than most other models in the full size range. Here are the specifications:

    --Gustav Mahler

  • "We have to prepare our cities for the increasing scarcity of resources by increasing their density and energy efficiency." -- Mathis Wackernagel

  • "Saying that you don't care about privacy because you got nothing to hide is no different than saying that you don't care about freedom of speech because you got nothing to say."

  • “Now every field is clothed with grass, and every tree with leaves; now the woods put forth their blossoms, and the year assumes its gay attire.”

  • “At the end of the day, no amount of investing, no amount of clean electrons, no amount of energy efficiency will save the natural world if we are not paying attention to it - if we are not paying attention to all the things that nature give us for free: clean air, clean water, breathtaking vistas, mountains for skiing, rivers for fishing, oceans for sailing, sunsets for poets, and landscapes for painters. What good is it to have wind-powered lights to brighten the night if you can't see anything green during the day? Just because we can't sell shares in nature doesn't mean it has no value.”
