About us

 GREETINGS FROM OUR SOLAR POWERED OFFICE: Well, we wanted to get this flier out in October, but a very busy fall delayed this. Our spring ‘08 was chilly (yet our last winter’s temps didn’t get below zero here). We had a hot enough summer to have a terrific garden and no late frosts damaged our fruit crops—the apples and plum trees were full, and the raccoons let us have our apricots, peaches and even the grapes too (they LOVE grapes). And we only had one day of smoke this past summer here, from forest fires in Idaho. Believe me, the occasional summer rains we had and lack of smoke let everyone breathe considerably easier.

For those of you who aren’t “on line”, or are beginning your project, we have an extremely informative Product Catalog on disc for $10 ($18 out of country)—essential for your energy library! Products, system sizing, pricing, components, importance of energy efficient appliances, battery care, and wind turbines are just some of the topics covered. If you are on-line, you can see example systems (costs, components and power output) at
To assist your information input, we’ve tried to develop as much on-line information as we can. For solar water pumping, see; for utility-tied photovoltaic systems, visit; for efficient AC appliances, DC ’fridges, coolers and freezers see; for natural and LP gas appliances, see Our main index page is and we now offer composting toilets at Visit our web pages and stay a while!

BATTERIES FOR BACK-UP POWER: In the wake of some of history’s most destructive hurricanes, storms and fire seasons, we have been getting many calls from people asking for a system that would allow them to utilize grid power, yet have independent power when a black-out hits, without the noise, hassle and fuel consumption of a generator.  There are several inverter companies that are making equipment that does just that.  Outback Power has taken a couple of their famous battery-based inverters and given them the ability to interact with the grid.  Used along side one of their new FlexMax charge controllers and a power source, you can charge up your batteries, which when full will remain in stand-by mode for the next power outage.  Once the batteries are full the inverter begins performing like a grid-tied inverter—powering the home and then sending the excess power back to the utilities for credit.  When a power outage hits, the inverter turns to the batteries to power your critical loads to get you through the dark times.  Unlike traditional battery based systems, the battery bank is much smaller since you are only powering those critical loads for a day or two at a time. In most cases we recommend 4 to 8 gel or AGM (absorbed glass mat) batteries.

Here is an example system that will provide power for a home’s critical back-up loads (4 CF light fixtures, efficient refrigerator, TV & VCR for a couple of hours, and a 3/4hp well pump—the latter being powered for 10-15 minutes a day) for 3 days in a solar climate similar to New Orleans, LA. 780W Grid-Tie PV System with Battery Back-up:

Fronius Batteryless Grid-tie System
Are you looking for a way to lower those ever-growing power bills or even get rid of them?  You may want to consider a solar electric grid-tied system.  These relatively simple systems take the power that you produce from your solar modules and use them to power your home.  If there is power left over, it will be diverted back to your power company—effectively slowing your meter or spinning it backwards.  If you need more power than you are producing, the power will be taken back from the power company and your meter will spin forward.  The goal is that at the end of your contract period (annual or monthly) you will have a decreased utility bill.  In many areas you may even get a credit, if you are making more power than you use. Plus, there are no expensive batteries to maintain.  Besides the solar modules, the other main component necessary is the grid-tied inverter.  This unit will take your high voltage DC from the solar array and invert it to 240V AC that can be used in your home and/or sold back to the utility company.  While there are several good grid-tie inverter models, this system (below) will feature the cost-effective and reliable Fronius IG inverter. These inverters come in sizes ranging from 2,000 to 12,000 watts.  The smaller of those inverters use a High Frequency Technology that enables them to have a conversion efficiency of 92.5%.  The larger of these (4000 & 5100watt) use their MIX concept, which utilizes two power stages--yielding increased efficiency during partial load situations. These units are also known for their ease of installation; they weigh in as the lightest of all the grid-tie inverters—at 26 to 42 pounds.   Add a Communication Card and a Datalogger and you can keep an eye on the power you are producing via computer and web. Soon there’ll be the larger IG Plus inverter (up to 12,000 watts) to be released soon!
Below is an example system.  Give us a call and we can design one for you!

Fronius power inverterCosts do not include freight, installation, home-run wiring, grounding wire and rods, wiring between disconnects and inverter, conduit, wire nuts or any site specific items needed for the installation. In Phoenix, AZ, this system will produce an average of 10.9kW per day or roughly 3986kW per year, with array oriented due south on a 4/12 pitch roof. In Sheridan, WY., in July with an average of five full sun hours per day, this system will produce 8.4kW/day.

The importance of keeping your S**** together! (that’s stuff, by the way).
Those of us who own renewable energy power systems generally know how crucial it may be to have your technical information on hand—and pronto! If you are having any problems, you will need to know what your major components are, your inverter brand and model, the kind of photovoltaic modules you have, size and capacity of battery bank, service records, etc. If you sell your place with its RE system, you will want to hand off a stack of manuals, as well as dates and invoicing information, to its new owner. Your installer or RE salesperson should have provided you with detailed technical drawings of your system. And of late, there’s been a rather insidious rash of thefts of solar modules and related equipment throughout the country. This is an expensive technology, and bad people are learning how to lift a solar array swiftly in the dark of the night.
First thing’s first: like any other important thing you own (car, home, etc.) your goods should be insured. A solar power system is no longer so esoteric that your insurance carriers cannot cost effectively provide coverage for it. Next, keep a list of serial numbers of all your equipment. All PV modules come with a sticker on the back that has its electrical information on it, as well as manufacturer and serial number. Your inverter and other components offers similar information. Pictures of your system may come in handy for documentation. While no one’s giving it away, you can generally get security mounting hardware (for your modules) that will help prevent theft. It may not deter a serious thief, but it will make stealing more difficult. And a metal engraver may not be a bad idea to personalize your goods in a discrete fashion.

As to our latest home/office system upgrade….
We just replaced our system’s batteries here at Oasis Montana. Our 16 old ones were nine years old, and we replaced them with slightly higher capacity batteries (Rolls/Surrette S-530s). Except for the occasional equalizing and topping off with distilled water, our system has operated flawlessly, and with no other maintenance during those nine years. Of course, I have gone out and
dutifully checked the connections annually; initially I tightened the lugs on the batteries a time or two. But I did coat the batteries with an anti-corrosive gel, and I have been amazed at how little maintenance this system has needed. We did also upgrade our little wind generator too (which has been working great for about ~2 years). By the way, if you are in need of some insomnia curing information on batteries, check out our page at ZZzzzzzzz……..

Renewable Energy Incentives—the good news and the bad.
The bad news is that the comprehensive energy bill passed by Congress was attached to the rich guy bail-out bill— which frankly we were not happy about. Whatever happened to fiscal responsibility? If I make bad business decisions, I don’t expect anyone to bail ME out! But, be as it may, there are some good improvements in tax credits for renewables, so hopefully it will make for a more level playing field (based on what incentives that have been available to fossil fuel and nuclear industries for decades). What started out as a true effort to advance renewable technologies ended up largely co-opted by petroleum interests; in addition to much needed assistance for the nation’s young renewable energy industry (and assistance to related homeowners and businesses), the bill included millions of dollars for oil shale, tar sands and coal...not exactly a grand commitment to clean, green power, to be sure. But, this bill is now law, and the incentives (after Jan. 1st, 2009) include: 30% tax credit for all solar power systems, which will remain in place until 2016. For wind, 30% tax credit of the cost of a system, up to $4000, limited to systems generating no more than 100kW. Also, for electric vehicles, there’s a new tax credit worth up to $7500 for the purchase of plug-in hybrid electric vehicles (PHEVs — which should be available as soon as 2010). For information on the different aspects of this bill, visit, or,, or and for incentives particular to your state, also visit The time is now to make the commitment to renewable energy!

New Enphase Inverters make an "AC" solar module???

Enphase Inverters are the first commercially available Micro-Inverter System for residential and commercial PV applications. Instead of the centralized inverter approach for a batteryless PV system, (that converts power from strings of modules), microinverters convert DC power from each module in a distributed approach. EnPhase AC solar module kit

The main key elements of an Enphase Micro-Inverter System:

  1. The Enphase Micro-Inverter (shown at the right)

  2. The EnergyManagement Unit

  3. The Enlighten web-based analytics and visualization.

All three elements are integrated to provide a comprehensive energy production and management system. The Enphase Micro-Inverter itself has a 15 year warranty, and the modules that work with them have a 20 to 25 year output warranty.

Features include:

  • Every module has maximum power point tracking (MPPT), increasing energy production for the entire system

  • No string calculations or combiner needed

  • No single point of system failure

  • Simplifies designing for roofs with multiple angles and orientations

  • The system includes 24/7 monitoring and management for each module.

These are available with 240V or 208V AC voltage output; call for inverter pricing (240VAC or 208VAC). One of the advantages of this ‘PV module/inverter’ is that purchasing a system can be spread out over time; at present we can offer an SGT-160 system, a single 160W module with this inverter built on to. The SGT-160 comes with everything you need to start generating your own solar power; all you need is a 240VAC power line to run through a disconnect, then to the location to where the panels are to be installed; after that everything gets plugged in. The SGT-160 comes with its panel, flush mounting system, and inverter built-in on the back. You can install just one, then as your finances dictate, you can add up to 15 more; once the first one is up, the rest just plug in. Here are the SGT-160 kit specifications: 64”L x 32”W x 4.5”D, weight 40 lbs.; the solar module has a max power output of 160W, nominal voltage is 24VDC. The inverter has a maximum output of 175W, with maximum voltage input of 54VDC, and AC voltage output of 240VAC, with peak inverter efficiency of 95%; UL 1741/IEEE1547 compliant. If you thought you couldn’t afford a solar electric PV system, it may be time to look at the Enphase Inverter System!

"This is not your grandfather's energy crisis"  -  Thomas L. Freidman

Renewable Energy and Alternative News Bites:

Comparing Denmark to the U.S. is not exactly apples and apples; Denmark is about the size of Illinois. But, there’s some food for thought in this article about how the Danes have attained their energy independence, using wind, biogas, co-gen facilities, and landfill technology innovations:
MIT has developed a way to bank solar energy at home; a U.S. scientist has developed a way of powering fuel cells that may make it practical for home owners to store solar energy to run their electrical loads at night. It’s a new catalyst that produces the oxygen and hydrogen that fuel cells use to generate electricity, while using a lot less energy that methods currently used. For more information visit
Biofuels are the major reason for a world-wide rise in food prices, according to this article by a World Bank economist; large increases in the U.S. and Europe in production of biofuels have reduced grain inventories and speculative trading. The story’s at
Ocean currents can save the world, says scientists. A new device that can harness energy from slow moving (i.e., less than one knot) ocean or river currents could provide enough power to run the world. The unit consists of a system of cylinders and springs that produces vortices, which in turn pull the cylinder up and down and create electricity. for the article.
