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.

The climate crisis of the 21st century has been caused largely by just 90 companies, which between them produced nearly two-thirds of the greenhouse gas emissions generated since the dawning of the industrial age, according to climate researcher and author Richard Heede at the Climate Accountability Institute in Colorado whose findings have been accepted for publication in the journal "Climatic Change." Half of the estimated emissions were produced just in the past 25 years — well past the date when governments and corporations became aware that rising greenhouse gas emissions from the burning of coal and oil were causing dangerous climate change. ….

*   Renewable Energy Gaining on Fossil Fuels: http://www.usatoday.com/story/money/markets/2014/01/31/renewable-energy-winning/5082181/.  Since 2007, electricity generation from coal has fallen 24.9% from 2.02 billion MW-hrs to 1.51 billion MW-hrs in 2012. 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. That compares to an average price of 9.6 cents per watt overall in the U.S.

Recent experiences with projects Vogtle and Olkiluoto, Finland show that cost estimates with nuclear tend to be unreliable. And in most cases, costs go up later. By contrast, since one only need weeks to months to build a solar park, everyone involved in such a project can rely on those very exact costs. They won’t change much while building it. Moreover, solar prices have dropped already by a factor of 200 in the last forty years and will continue getting cheaper.
