"Tulip poplar" as you know is a misnomer for Liriodendron, a member of the
magnolia family.  Fast growing but basically useless tree except for shade;
has a love affair with lightning due to high H20 content.

Re: [MBZ] OT: Practical solar application

2015-09-08 Thread Curt Raymond via Mercedes
Ash is what they make baseball bats out of, its extremely straight grained but 
a bit flexible which is what makes it good for bats. The same straight nature 
makes it easy to split, not so easy as oak as its kind of fibrous, meaning the 
fibers kind of cling together while you try to get the pieces apart. I haven't 
had a lot of experience with it, we don't have any on the farm although it is 
native to our area.
OSB is Oriented Strand Board, aka wafer board, the plywood like stuff they make 
houses out of. It uses cheap woods like poplar. Last spring our neighbor was 
getting (IIRC) $40/cord for poplar. That was what he was actually getting paid 
by the harvester, that guy was getting probably $80 at the mill.
Remember also when I say poplar I mean quaking aspen not the tulip polar 
furniture makers use.

Except that a careful shopper can cut the price in half and electricity isn't 
getting cheaper every year.
Solar systems are going in all over the place in MA. We have limited 
transmission capacity so point generation makes way more sense.The panels are 
rated for 30 years at which point they aren't broken, they just decrease in 
capacity. With no moving parts they never fail except for impact damage...
In the next 3-5 years I plan to put solar hot water on our house, payback is in 
the 3-5 year range. My aunt and uncle have it and crow about it being the best 
thing since sliced bread. I need to upgrade our heat/hot water system to 
support it first...

Re: [MBZ] OT: Practical solar application

2015-09-08 Thread Curt Raymond via Mercedes
Dad just bought the panel listed below and installed it on our camp. The price 
on that setup varies WILDLY on Amazon, I knew that (I've been watching them for 
a year) so we bought when it was low at $150. He's got 2x 35ah wheelchair 
batteries for about $100 I think plus a 400w inverter (we're powering a ceiling 
fan and range hood plus charging phones etc) so we're in maybe $300 total. 
Dad reports (I spoke to him last night) that the charge controller starts 
blinking with incoming power just as soon as dawn breaks and stays going until 
the sun is fully down. He's got a Kill-A-Watt on the output so he knows his 
output power but neglected to get anything for the incoming side which is 
something we'll add on the next trip. Overall he's satisfied with the system, 
the ceiling fan pulls around 50 watts, the range hood with light is 90w so 
we've got decent capacity (35ah or say 400 watt hours) for what we've got now. 
He's planning on another panel and 2 more batteries next year, with 5 guys at 
deer camp charging phones and limited sunlight we'll want the extra capacity.

A heating pad is a heater.

"almost no current" when there is 115 VAC in the wall outlet
is not the same as battery power! 

> Typically these:
> http://www.amazon.com/Hydrofarm-MT10006--19-1-2-Inch-Seedling/dp/B0001WV010/

That page reports "The Seedling Heat Mat uses 17 watts".

With a 100% efficient inverter and 12 VDC battery, that will
draw about 1.5 amps.  

Figuring on inverter losses, etc., lets round that off to 2 A.

To run one for 24 hours would require (2 x 24) 48 Amp-Hours (Ah).

Since this would be about the time of the spring equinox,
there should be about 12 hours of sunlight.  That is NOT 12
hours of max output from a photo-voltaic panel, but I'll
ignore that for now.  I expect you will want the pv panel to
run the heater _and_ charge the battery, so it will need at
least 4 A output - or about 50 W.

Since it is never good to let a wet cell run all the way
down, and to allow for decreased capacity over time, that
would suggest a 50 Ah battery to effectively power one
heater overnight.  (24 Ah draw from a 2 A load for 12 hours -
rounded up.)

That amounts to a 20 W inverter, a 50 W pv panel, and a 50 Ah
battery - for each heating pad.  A quick look at Amazon for
prices results in almost $500 to run two heat pads.

How many do you use?  How much to run an AC power cord?

All you really need are a couple of group 49 or 93 batteries, a battery charger

Every morning and evening, put a freshly charged battery in the shed and take
the other one to

direct heat rather than PV.  Anybody work with those?

Medium-large name brand home panels can be had for under $1 per rated 
watt.
So figure $0.20-0.25 per daily watt-hour, plus mounts, wiring, 
inverter, etc.
My after tax rate for electricity is 0.14+, so it can pay off in the 
lifetime
of the equipment now, the bare PV panel cost can be recovered in 4-5 
years.


Electricity here is, IIRC, $0.055/kWH, so it would take nearly 3x

I guess I would be. All it does is raise the temperature at the base 
of the

seedling flats to about 80 degrees.


All my 30kW electric furnace does is raise the temperature at the
base of the house to about 80 degrees.

Heat is expensive!  Use the Kill-a-watt, and _know_.

All you really need are a couple of group 49 or 93 batteries, a battery charger
and a cheap inverter. 

Every morning and evening, put a freshly charged battery in the shed and take
the other one to
the house and put it on the charger. Consider it free exercise carrying 50lb
batteries around.

A heating pad is a heater.

"almost no current" when there is 115 VAC in the wall outlet
is not the same as battery power! 

> Typically these:
> http://www.amazon.com/Hydrofarm-MT10006--19-1-2-Inch-Seedling/dp/B0001WV010/

That page reports "The Seedling Heat Mat uses 17 watts".

With a 100% efficient inverter and 12 VDC battery, that will
draw about 1.5 amps.  

Figuring on inverter losses, etc., lets round that off to 2 A.

To run one for 24 hours would require (2 x 24) 48 Amp-Hours (Ah).

Since this would be about the time of the spring equinox,
there should be about 12 hours of sunlight.  That is NOT 12
hours of max output from a photo-voltaic panel, but I'll
ignore that for now.  I expect you will want the pv panel to
run the heater _and_ charge the battery, so it will need at
least 4 A output - or about 50 W.

Since it is never good to let a wet cell run all the way
down, and to allow for decreased capacity over time, that
would suggest a 50 Ah battery to effectively power one
heater overnight.  (24 Ah draw from a 2 A load for 12 hours -
rounded up.)

That amounts to a 20 W inverter, a 50 W pv panel, and a 50 Ah
battery - for each heating pad.  A quick look at Amazon for
prices results in almost $500 to run two heat pads.

How many do you use?  How much to run an AC power cord?

If you want to go solar...I just did a solar install on the motor home. I
put 2 100W panels on the roof, an MPPT controller (so I could wire the
panels in series and have the wiring handle the higher voltage more
efficiently) and 2 Group 27 deep cycle batteries wired in parallel.  The
system works great.  The MH already had a 1600W inverter which I use very
little.

Total cost for all components was about $750. I spent more on the panels to
get flexible ones that I could tape with 3M VHB tape to the curved
fiberglass roof. Rigid panels would cost about $50-100 less IIRC.

The way to go is to figure out what your daily amperage usage would be.
Battery capacity should be at least twice that amount, and solar input
should obviously be enough to exceed usage.

I agree with others that the heat requirement likely would overwhelm the
capabilities of a solar system.

Just Google: "110v solar power kit for shed"

But they aren't cheap if you get a useful capacity and they won't last near

All correct - but I understood the question to be about a kit.

The need for al the "interconnecting paraphernalia" doesn't
mean a "simple kit" can't be packaged and sold.  A box with a
NEMA 5-15 socket on the side and a solar controller, battery,
and inverter inside.  Connect photo-voltaic panel and plug in
your load.

2015-09-04 Thread Jim Cathey via Mercedes
Thanks - that helps.  I wonder why there is no simple kit that goes 
from PV
to 110 V without all the interconnecting parapernalia, battery, 
inverters,

etc.


Because unlike a politician's promise, the 'kit' purchaser would
expect results and would be mightily pissed when the simple kit didn't
actually deliver.  The process is _inherently_ not simple, and no
amount of wishing will make it so.

Solar for intermittent lighting and battery charging would be OK.
For any kind of heating, IMHO it's a non-starter.  The size of
the necessary system would be extremely cost-prohibitive.  And
there's ongoing maintenance requirements, and batteries have
a finite life, etc.

Your most satisfactory solution, and the cheapest one that will
meet your stated needs, will be a DIY install of a 12-gauge circuit
drop underground.  I'd recommend a 220V circuit, you'll get both
voltages that way and have a lot more potential power you could
exploit in the future.  (Welder, hot tub, etc.)

I had a final plumbing and gas line inspection yesterday, the inspector 
is a cool guy I like, he sorta looked at it for about 10 seconds and 
signed off, we chatted for another half hour and he recommended I do the 
rest of the work in the house without telling anyone about it.  Turns 
out he also signed off on the final electrical inspection at the last 
visit, I don't recall that and was a little hesitant about it.  He also 
suggested that this permit resets the clock another 6 months, so I 
should wait until next year for the final finals so the tax man doesn't 
screw me this year.


All that and no consultation from Mr. Johnny Walker... it's amazing how 
helpful all the inspectors have been and how demonstrating a bit of 
competence and cooperation works.

Using the vibrating blade on a Ditch Witch, roots get sawed through slowly, and
rocks smaller
than softballs get shoved out of the way. 5+ feet per minute speeds are
achievable while
planting wire and/or poly irrigation pipe about 18" deep.

I bet a sprinkler installation crew would gladly pull your cable for a dollar or
two a foot. 
Then, if you want to be legal, have an electrician hook up both ends.

Or you can weld a conduit elbow to a subsoiler and bury (24 inches) the
cable using a tractor.  I ran mine about 200 ft.  This was before I had a
tractor so I hired a local guy with a ditcher to dig (and backfill) the
ditch for $1 a foot.  For wire I  used 10-2 UF (with ground) from Lowes,
plastic conduit where it enters and leaves the ground, and direct bury
between.  There is a 20 amp GFCI breaker feeding the circuit and a GFCI
outlet at the other end.  The whole thing probably cost $300 but folks in
rural NC aren't anal about licensed electricians for small jobs.  

I would be interested to learn how Andrew's environmentally-friendly

Because it cannot be done without all the interconnecting paraphernalia
(correct spelling).

PV cells put out low voltage direct (not changing polarity) current. You
can string them in series to get a higher voltage direct current output,
but it is still direct current.

Household power is a moderate voltage alternating (changing polarity)
current. You have to have an electronic device (an inverter) to change
the direct current output of PV cells to alternating current.

If you want the power available when the sun is not shining, you need to
store the energy somehow. The easiest is in a chemical reaction in a
rechargeble battery.

Yes, that is correct! But you do need GFCI (in a 20 A or less breaker, I
presume, rather than a 20 A breaker at the source end and a GFCI
receptacle at the load end).

I still, however, would not feel safe putting a 120 VAC line 12" down.

Andrew, google the word "shovel"  I have relocated my water line, dug up 
my buried power line, relocated my buried phone line (OK my wife did that 
because she wanted to do something useful outside) using a shovel.  It is 
ancient technology.  you only have to go down a little ways and bury some 
1" PVC conduit which is very cheap.  Get some 12-2  Romex and pull it 
through (do it while you are burying the sections of conduit, it is easier 
then, lay down your wire then slide the conduit over it, be careful not to 
get glue inside the conduit) leaving enough at each end to reach whatever 
you are connecting each end to.  Then if you must call the electrician, 
have him put an outlet or 4 in your shed, maybe a switched outlet for your 
lights, and connect the other end to your panel with a GFCI breaker, or to 
another outlet somewhere and put in a new GFCI outlet to protect it.  I 
would just do it and be done with it, forget the electrician.  An 
afternoon of work, a coupla hundred dollars of stuff, and you have good 
solid power for whatever you need.


But that's just me.

As far as plugging 110V stuff into your solar set-up, assuming you are 
using a panel to charge a deep cycle 12V battery, you buy a 12V -> 11oV 
inverter from HF, wire that to your battery terminals (either cut off the 
ciggy llghter plug and put it to the battery directly, or buy a ciggy 
lighter plug with bare ends to connect to the battery).  The inverter will 
have a regular plug on it to plug your stuff into, but you need to be 
mindful of the wattage of the inverter and the load of your heaters and 
lights or whatever.


BTW camping/RV stores will sell all kinds of 12V stuff you can use right 
off the battery.  I favor the blender for making 'ritas in the truck, 
though mama's new ML has a 110V plug in it too.

A solar panel will generate direct current (DC).  A power
cell - and therefore a battery - can only store DC.  If you
need alternating current (AC), then a converter is needed.
It is called an "inverter".   Small ones (low power) are
pretty cheap.  Big ones are not.  Ideal is to get an inverter
with a power rating close to your power needs.  If you have
80 Watts of seedling heaters, get a 100-120 W inverter, not a
750 W.

The process of creating AC from DC is not perfect.  Thus to
get 80 W of AC will typically require 90-110 W of DC.

The capacity of the photo-voltaic panel, capacity of the
battery, and the power rating of the inverter all depend on
the size of the load.

Agreed.  +1  but, I'd suggest a trenching spade in place of a shovel. 
Makes quicker work of it.  Also,  I've been told that you cant run 
type NM ("romex") in a conduit as it is against code.  Makes no sense 
to me, but you have to use the "pulling type"  (I forget the type) 
single wires in conduit.  Apparently the extra sheathing/insulation 
is a no-no.   Simpler to bury type UF 12-2 WG.

for solar:  Much simpler to use a PV panel to generate, one or more 
12V batteries to store, and 12vDC lighting and heater units.   No 
inverter needed unless you want to run a corded drill.


a century ago, the Delco light plant worked in a similar manner.  A 
generator, generating DC, batteries, perhaps a wincharger for "free" 
electricity,   Low voltage DC incandescent bulbs for light.  Perhaps 
a DC motor on the Maytag washing machine.  It worked in homes and 
farms for decades before "lectricty" came on poles.


As practicality, bury a 12-2 WG type UF wire with a trenching spade 
and quit whining.

A solar panel will generate direct current (DC).  A power
cell - and therefore a battery - can only store DC.  If you
need alternating current (AC), then a converter is needed.
It is called an "inverter".   Small ones (low power) are
pretty cheap.  Big ones are not.  Ideal is to get an inverter
with a power rating close to your power needs.  If you have
80 Watts of seedling heaters, get a 100-120 W inverter, not a
750 W.

The process of creating AC from DC is not perfect.  Thus to
get 80 W of AC will typically require 90-110 W of DC. 


The capacity of the photo-voltaic panel, capacity of the
battery, and the power rating of the inverter all depend on
the size of the load.

Electrical code book does NOT permit running Romex wire inside conduit.
Thus, you should not.

I suggest you rent a walk behind engine driven trencher. With reasonable
soil, you can trench 100 ft in 1 hr of run time to a depth of 18 inches.
Then lay "Direct burial Romex wire" into the trench. Lowes and Home Depot
will guide you to the right wire [usually].

A rake drags the loose soil back into the trench and you are covered.. The
tool makes a nice 4" trench, just wide enough to run  a water line, or
wire, I've used one many times and always well worth the rental fee.

Caution: As always, call your local blue stake safety people to ensure you
are not trenching through a gas line or electrical cable... Safety first..

I have been thinking about something similar for a shed I want to 
build.  Harbor Freight has some fairly cheap solar panels of not 
particularly high wattage, that would be cheap enough to do a test set 
up.  Buy one, hook it to a battery/inverter  (I think they might come 
with a 12V battery charger circuit but not sure) and see how much charge 
you can get out of the thing to keep a battery charged with some use.  
You might also want to look at the heat mats, a lot of those things are 
not direct 110V but use a transformer power supply to get, maybe, 12V or 
something similar, so you could possibly run them directly off a 
battery.  Or go to the junkyard and get some heating elements out of 
some car seats?  You can probably buy the heating wire too, I put it in 
my bathroom tile floor, it runs off 110V through some sort of box that 
might step it down, I don't know.  There is probably 12V heating element 
stuff out there somewhere, eBay is your friend.

HF also have some LED lights with a little solar panel to charge 
batteries for like $40, not sure the light output but again, cheap 
enough to test out.  Costco have been selling some LED shop lights, 
110V, that you could probably run off an inverter, not sure what they 
draw but you could check.  Or buy some 12V LED lights from China (I 
bought a load of 110V UG10 spots that are incredible and have been 
working fine for 6 months now, 12V is a standard too for those fancy 
track lights) and hook them up.  If you are interested I can send some 
links to the sockets and lights.  They don't use much amps for a lot of 
light.

You could probably get a reasonable set up for a coupla $100.  Or just 
run some conduit and a circuit out to the shed from the house...

Dad just installed a 100w solar system at camp. Bought a kit from Amazon plus a 
couple electric wheelchair batteries. I think the single panel is too small but 
he didn't want to spend too much money.
How much power do the grow mats pull? Can't be too much, I still think a 100w 
panel would be undersized, especially in the spring, 200w will probably be too 
much in summer but thats an okay problem to have. Building the system is easy, 
you'll need an inverter for the 110v but a 400w version will be cheap. Use an 
only MB starting battery for cheap storage or buy something better for big 
money. 
I suspect as dad ages we'll want more storage capacity and I'll pony up for 
iron nickel batteries which will last most of the rest of my life but will cost 
more than the rest of the system put together...

2015-09-03 Thread Dan Penoff via Mercedes
There probably is if you look around.  It won’t be cheap, however.

Doing it yourself is really pretty easy.  As previously described, you only 
need three things:

PV panel

12V battery

Inverter (DC to AC)

Work backwards by calculating your load.  If you’ve got 100W of 110VAC load, 
you’ll need an inverter that can produce slightly more than that (120-150 
watts).  If you don’t want to discharge your battery a lot, make sure your PV 
output matches or exceeds the input to the inverter (all of this in wattage.)

It’s a good idea if you’re using a conventional battery to go with a deep cycle 
one, like the kind used for trolling motors.  They’re easy to locate any place 
that sells automotive batteries.

Some of your loads might be 12VDC, which can be fed directly off the battery/PV 
setup without even considering the inverter.  Their load will decrease the 
amount of power going to the inverter, but again, if the load on the inverter 
isn’t that high, it won’t matter.

Go and buy a 100 foot power cord. Minimum 12/3. I saw one in a flyer

That should be sufficient for your heating mats unless you are using a 
lot of them.
Don't expect any code issues if you just plug it in at the house and at 
the shed.


Get the LED lamp with the little solar panel to light the shed.

There is a sunny spot where I could erect a solar panel, about 15' from the

Anybody out there work with practical solar applications?

Basic lighting is easy. They sell small solar powered LED lamps all over 
for next to nothing. I have one on my garage that lights the path beside 
it whenever I walk through.


However, unless the shed is a half mile away, let me suggest an 
extension cord to the house is much simpler and less expensive than a 
setup sufficient to provide 120V to electric heating mats.

A solar panel will generate direct current (DC).  A power
cell - and therefore a battery - can only store DC.  If you
need alternating current (AC), then a converter is needed.
It is called an "inverter".   Small ones (low power) are
pretty cheap.  Big ones are not.  Ideal is to get an inverter
with a power rating close to your power needs.  If you have
80 Watts of seedling heaters, get a 100-120 W inverter, not a
750 W.

The process of creating AC from DC is not perfect.  Thus to
get 80 W of AC will typically require 90-110 W of DC.  

The capacity of the photo-voltaic panel, capacity of the
battery, and the power rating of the inverter all depend on
the size of the load.

True.

It’s against code to run phone with power, or any other signal wiring, I 
believe.  Not to mention you risk inducing a voltage into it, which can wreak 
all kinds of havoc.

I have been thinking about something similar for a shed I want to 
build.  Harbor Freight has some fairly cheap solar panels of not 
particularly high wattage, that would be cheap enough to do a test set 
up.  Buy one, hook it to a battery/inverter  (I think they might come 
with a 12V battery charger circuit but not sure) and see how much charge 
you can get out of the thing to keep a battery charged with some use.  
You might also want to look at the heat mats, a lot of those things are 
not direct 110V but use a transformer power supply to get, maybe, 12V or 
something similar, so you could possibly run them directly off a 
battery.  Or go to the junkyard and get some heating elements out of 
some car seats?  You can probably buy the heating wire too, I put it in 
my bathroom tile floor, it runs off 110V through some sort of box that 
might step it down, I don't know.  There is probably 12V heating element 
stuff out there somewhere, eBay is your friend.


HF also have some LED lights with a little solar panel to charge 
batteries for like $40, not sure the light output but again, cheap 
enough to test out.  Costco have been selling some LED shop lights, 
110V, that you could probably run off an inverter, not sure what they 
draw but you could check.  Or buy some 12V LED lights from China (I 
bought a load of 110V UG10 spots that are incredible and have been 
working fine for 6 months now, 12V is a standard too for those fancy 
track lights) and hook them up.  If you are interested I can send some 
links to the sockets and lights.  They don't use much amps for a lot of 
light.


You could probably get a reasonable set up for a coupla $100.  Or just 
run some conduit and a circuit out to the shed from the house...
