From Oasis Montana
Greetings From Our Solar Powered Office: What a summer it
was! Too short, as always—but with some beneficial rains that helped
with the forest fires. Then, we had unusually hot weather in
September, and a nasty cold snap early in October. Still, the
orchard and garden were very generous to us and our friends, with
much cider, plums, potatoes, carrots and other produce to share.
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
www.PVsolarpumps.com; for utility-tied photovoltaic systems, visit
www.grid-tie.com; for efficient AC appliances, DC ’fridges, coolers
and freezers see www.eco-fridge.com; for natural and LP gas
appliances, see www.LPappliances.com. Our main index page is
www.oasismontana.com and we now offer composting toilets at
www.eco-potty.com. Visit our web pages and stay a while!
30% FEDERAL TAX CREDIT —and
reduced solar module pricing make this the ideal time to get your PV
system up and running!
Solar modules have come down as much as 30% in the past year, so
check our pricing page for what modules best suit your power project
(or give us a call). Since the paperwork involving these incentives
can be a little confusing, peruse these online sources for more
http://www.dsireusa.org for a state-by-state database of all
incentives available to U.S. consumers.

for the personal residential tax credit.
The Allure of Wind Power!
Many people are enamored with the prospect of wind power
generation—and unfortunately some make the investment before they
have really ascertained that they have the resource for a wind
system. Solar modules are so boring, they just sit there….but wind
machines are a form of kinetic sculpture, and their spinning
movement is quite entrancing! BUT, while folks are drawn to wind
generation, photovoltaics are often a better approach (often because
wind looks like it’s doing something even when it isn’t, while PV
tends to be the opposite). And there are important issues with wind
turbines; wind devices need proper siting to avoid turbulence, and
most neighborhoods have tower restrictions. Wind generators should
be mounted at least 30 ft. above anything else within 500 ft., and
in an urban situation, usually your lot must be at least 1/2 half
acre or larger in size. Permits, neighbors, variances….all are
factors to be considered before spending money on a wind generator.
The larger the blade span, the greater the swept wind area, so if
you do have an excellent site for wind power, go big and high for
the greatest power return.
If you have some idea of mounting a wind genny on your house….well,
get over it. It’s a very bad idea, and even smaller units have been
known to vibrate a structure apart. Visit http://www.wind-works.org/articles/RoofTopMounting.html
for an article about roof-mounted wind machines. And there’s another
site that works to dispel myths about urban wind generators at
http://www.urbanturbines.org (there’s some scary pictures here!). A
pole stuck 10 ft. above your garage is not going to generate much;
now I’m not saying you can’t have a wind turbine in the city limits,
but unless you have good clean wind, preferably mostly from one
direction, with no obstacles to reduce the wind resource, it’s not
going to be a good investment.
Of late we have been receiving requests to become dealers for
several types of Vertical Axis Wind Turbines (VAWTs). These devices
sort of look like egg-beaters, mounted on a vertical central pole
and spinning like a top. In spite of their claims, the basic design
is not suitable, at present, for high power production. And while
they do look cool, no matter how high wind speeds are, the blades
being turned are offset by an equal amount of wind hitting the
opposing blades—so never more than 50% of the winds can be utilized
to create rotation, no matter how efficient the blade design. The
three bladed horizontal axis models still make the most power for
their design. And so, if you WERE seriously considering a
residential, battery-based, grid-tied wind generation system….it
just might entail these components:
- Outback GTFX2524 inverter (2500W continuous
rating, 24V inverter)
- Outback Power MATE controller (system programmer
- Pair 10' 4/0 inverter to battery cables
- XL1 Wind Generator
- Temp Sensor
- Midnight E-Panel, two 60A DC breakers
- 8 - 6V Batteries (no cost included for these)
- 80 ft. tilt-up tower kit
So I have a total of $8100 (approximate; see current
pricing) before freight, batteries
& interconnects, site work, installation, wire runs, ground rod,
those sorts of things. We have had XL.1 turbines in the field since
2002 with few problems, and you can view the installation manual for
this tough turbine at http://www.bergey.com. How much power this
will make at your site depends on your average wind speeds, local
turbulence, and elevation. You can view maps of wind resources at
these sites: http:/www.windpowermaps.org,
http://www.nrel.gov/wind/resource_assessment.html and http://www.windpoweringamerica.gov/wind_maps.asp.
You may also want to consult with your local weather resources and
airports—always good places to check for average wind speeds.
|To design a power system for you, we need your power
requirements (electrical load information). See our web
page for system sizing information and examples of power
systems, which are based on the part of the country
you’re in and how much sunlight you receive. We have
design information on our web site, so please feel free
to utilize this. Or, we also offer a product and design
information CD for just $10.00 ($18
international)-—filled with information for your energy
library! We also have a paper catalog, which costs $15
for U.S. residents.

Kill A Watt Meter:
The Electricity Detector and Monitor can educate you about your
monthly electric bill and help you save a lot of money. You can now
be a ’detective’ and ascertain what appliances are actually worth
keeping plugged in. Simply plug in the Kill A Watt meter, connect
your appliances to it and Kill a Watt will assess how efficient it
really is, showing you the instantaneous power used, and also
cumulative energy or kilowatt-hours used.
Kill a Watt, with large LCD display, will count consumption by the
kilowatt-hour, same as your local utility. With the help of Kill a
Watt you can figure out your electrical expenses by the day, week,
month or year on a given device. Kill a Watt can check the quality
of your power by monitoring Voltage, Line Frequency, and Power
Factor. Still just $25.
Now you'll know if it is time to install a power strip on your
entertainment center instead of feeding those ghosts loads while you
are sleeping or away from home. Or, is that laptop really cheaper to
power than a desktop PC?

(depending on your elevation and constancy of wind).
Technical specifications: rotor diameter is one meter (39”);
rated wind velocity is 28 mph; cut-in rpm 350. At 14 lbs. it is easy
to mount on any 1.5” (48.4mm) schedule 40 steel pipe (commonly
available in most hardware or plumbing stores) and it carries a
three year limited manufacturer’s warranty. Other features:
- Only two moving parts and sealed for life bearings
- Proprietary 3-phase axial PMA utilizing neodymium iron
- Suitable for domestic or marine applications
- Quiet operation with low TSR motor

from overcharging; it’s compact and easy to install, and
incorporates a 300W resistor/heater and controller in a stout 18
gauge powder-coated steel enclosure.
If you have been considering the addition of wind to your PV
system—or you are planning to add a wind generator to your sail-boat
or catamaran, now is the time to try a Chinook! The turbine and
controller is $675 plus freight. The next batch in production should
be ready to ship just before Thanksgiving. We have specs and a copy
of the manual we can e-mail, if you want more information!
WATCH OUT FOR ENERGY SCAMMERS……
While it is wonderful that our federal government has finally
stepped up to the plate with its renewable tax incentives, there are
always unscrupulous persons waiting to take advantage of people’s
interest in these kinds of power systems. There was an article in
AARP’s last newsletter about the dangers of scammers, and how you can
avoid them at
There are other scammers out there too; of late there’ve been many
e-mails about ’making your own solar modules’ with claims of
’powering your home for a $200 investment’. While there are kits to
build your own modules, they are better suited for the student or
hobby endeavor. We are getting calls from folks wanting to sell
power back to their utility with their home-made solar modules or
wind generators. Unfortunately most people are clueless as to the
input requirement for these grid-tie inverters, and it’s a rude
awakening when they are told that only UL approved components are
legal and National Electric Code safe for grid-tie systems. And if
you think that $200 of home-made PV panels will power the average
home, there’s a bridge somewhere that’s for sale cheap too….
SOLAR HEATED STOCK WATERERS!
customers in northern climates have sought ways to keep their
animals watered in below freezing conditions—and we finally have
something for you. The SUNTANK (25 gallon model pictured at right)
will keep your water freeze-free to wind chill of 20 degrees below
zero, and the 42 gallon unit will work to -50 degrees F. These can
be filled from the top with a hose or you can have a direct line
attached with auto-fill and shut-off float to keep full. Call
Other features include:
- Durable! Units used and tested for 18 years are still going
- No freeze-ups, never rusts.
- No fuel or electricity needed, so it can be placed anywhere
in un-obscured sunlight.
- No risk of electrical shock to livestock, with a
shatter-proof passive solar collector.
- No costly fuel or electricity; uses energy from the sun,
still absorbs UV on cloudy days.
- SAVES time and money, so it pays for itself faster.
- Will NOT freeze even when livestock don't drink. Easy
accessible water for livestock, even in ice and snow conditions.
- MADE IN THE U.S.A.!
There’s no minimum number of livestock needed, and this also
keeps water cool and algae-free in summer. Closed system helps stop
West Nile Virus and other diseases. You may have to fence out the
collector side to avoid shading from stock. The 42 gallon unit is
guaranteed to -50F degrees below zero, and the 25 gallon unit
guaranteed to -20 degrees below zero -- during winter conditions
with wind chill factor included.
Renewable Energy and Alternative News Bites:
Kudos to U.S. Senator Sherrod Brown for introducing the
"Investments for Manufacturing Progress and Clean Technology
(IMPACT) Act of 2009." The IMPACT Act would provide resources for
small- and medium-sized manufacturers through a 2-year, $30 billion
manufacturing revolving loan fund, which will provide much needed
liquidity for domestic manufacturers to improve processes, to retool
and expand production of clean energy products. The Apollo Alliance
estimates that, once enacted, the bill will create 680,000 direct
manufacturing jobs and 2 million indirect jobs over 5 years.

Intermittency Not a Problem for Wind Power, Say European
reports published in the past month by the National Grid, and other
energy consultancies, all come to the same conclusion - that large
scale deployment of wind energy does away with the problems of
variable wind. The NGO report, "Managing Variability," published by WWF, RSPB, Greenpeace and Friends of the Earth, also claims that
breakdowns in coal and gas plants generally pose more of a threat to
the stability of utility networks than the relatively benign
variations in the output of wind plant.

New Economic Data Released on Clean Energy Legislation:
http://www.nrdc.org/media/2009/090917.asp Under the American Clean
Energy and Security Act, there will be more jobs, less global
warming pollution and greater security, all for less than the cost
of a postage stamp a day (per American household), according to “A
Clean Energy Bargain” analysis. The report found that ACES will
drive investments in clean energy and energy efficiency of more than
$300 billion by 2030.
