Solar Powered Fish House Build

Recommended Posts

2017 update..  

 

Solar panels are still working great. I think if I would do it again I would not put the solar panels on the roof I would mount them all on the side.   It is a cleaner look having them on the roof but with heavy snow it's a bit of a pain to get the snow off the solar panels.

Great to know Princeton, did you ever get a scale under this?  Just wondering on the weight.  I am building one simular, but it wont be half as nice or as finished as yours this season.  however I am happy with the frame and options I can add in the future.

I have not weighed it.  I tried to keep it as light as possible and it pulls well by my wheeler.  I am sure it is well under 2,000 fully loaded.

Very sweet shack you have there. How does it pull with those skids? I noticed bebergs now has changed their design to a "floating" type ski. Does yours ride up on top of the snow and slush or does it kind of drag? Thanks for the review

That really depends on the snow.  It will ride up on top of harder snow and generally  plows more through the lighter snow.  All depends on the snow.

2018 update.    Solar panels and charge controlers still going strong on the house.

Was able to just pull it out and had full charge on batteries.  Was fishing in 20 mins from the time I started pulling it out of the field.

 

Upgraded my wheeler to a Polaris Ranger with a cab and chains, makes pulling the house around the lake alot more comfortable.

I built this fish house last year with the goal of having a house that was semi-permanent, light weight, warm, solar powered and a Irish Pub smile. I have had a few questions from folks as to how I went about the build so I figured that I would start my own post to describe the build.

 

The house is a custom built 8x12 Aluma Lite V front aluminum skid house that I purchased from Bebergs. The house was unfinished but included 2-3 inches of spray foam insulation. It sleeps 2 and has a LED TV/DVD player, bathroom, media player for movies, inputs for fish cam, car alarm, stereo and inverter. I wanted to be able to leave it on the lake so that my Dad could use it during the week (he is within walking distance of the house) and I would use it on the weekends. This house is very light and weighs around 1,800 pounds fully loaded, I pull it with my 350 big bear with chains on the tires.

I installed 3 Unisolar pvl-68 flexible panels for a total output of 204 watts. The roof of the house is curved so I installed the panels to one side of the roof. These panels come in a roll and have a very strong adhesive on their back. They are very dependable and should last 20 years. To go along with the panels I installed a Morningstar dual battery charge controller and two 100+ Ah batteries to store the energy. I set one battery up to run the essentials like the lights and the heater and the other is the accessory battery, they each have their own circuit breaker. The accessory battery has a disconnect switch ensure that there are no phantom loads when we are away.

 

Here are the panels on the roof (sorry the roof is dirty):

Here are the batteries, solar charge controller, inverter and circuit breakers.

Charge controller read out - gives voltage on the batteries as well as tells you how much energy you are generating.

The key to make all this work you need to install very low draw accessories including led lights, LED DC TV and a low draw stereo. I did opt to go with a forced air furnace which takes the most power to run. If you have room I would suggest a non forced air furnace.

 

You need to look at the current draw of all devices and how long each one will run to determine the amount of solar capacity that you need. Originally we were only going to put two panels on the roof - we decided to put 3 on just to be on the safe side.

 

The stereo that I installed was a Kicker (model PXi.50) made low draw head unit that takes headphone or I Phone inputs - you plug it into your phone to play music. They make these to go on ATV's. I also added a USB charger to it so that you can charge your phone as well. (for some reason this pic is sideways)

I used the house pretty much every weekend last winter and my Dad used it one day out of the week. During the week the solar panels charged the batteries back to the 200 Ah capacity, during the weekend we would use around 60-70 Ah each day leaving a reserve + whatever the panels would generate. On a normal day the panels would generate between 40-50 Ah of power. One week we even left the heat on all week and we did not run out of power - a side note is that the house only burns 30 lbs of propane per week with the heat on.

 

We never ran out of power (although there were times that we were getting close to just running lights and heat). The main thing is to keep a mindful eye on your battery status.

 

Given the sun is so low on the horizon in the winter I would probably put the panels on the side of the fish house - I choose aesthetics over functionality and put them on the roof. The most that the panels would put out in the winter was 10 amps, in the summer it runs over 16 amps. They would generate more if they were on side of the house. If you have a flat roof I do not think that the panels would be very efficient in the winter. If you do put them on the side I would go with the more traditional solar panels and not the self adhesive ones.

 

The huge benefit is that we do not have to run a generator or carry batteries out to the house. It is always ready to go and has power even in the summer if the guys want to tip a few back.

 

Let me know if you have any questions. Any one else using solar on their house?

My generator took a dump on me this weekend. I'm sizing out my solar setup and I think i'm calculating my TV incorrectly @10.14 Amps, or an estimated 50AH usage per day. That includes an assumption of 85% efficiency for a inverter to power it. Is that how you set your TV up or was it 12v? I'm unable to see the picture of the one from Amazon..

10 amps seems kinda crazy... what is the model of the TV?

I don't think there is any TV that would use 10 amps. It's probably more like 1 amp. Something like a vacuum cleaner would take around 10 amps.

The tv I have uses 3 amps at 12 VDC, so it uses very little power.  Here is the model I bought on Amazon.  There are others like it.

I did a lot of research and knew that I wanted a 32" TV w/ DVD. Here is what I got....

 

https://www.walmart.com/ip/Sceptre-32-Class-FHD-1080P-LED-TV-E325BD-F-with-Built-in-DVD/46784933

 

It draws roughly 30 watts... so about 3 amps when you figure in the 20% overhead of the inverter. We usually only running in when on the generator, but have had no issues running on the inverter either. I did some research on inverters... The bigger you go up in size, the more that power you seem to lose. For example, a 1000 watt inverter may be 95% efficient at when you are drawing 900 watts, but it is only 80% efficient when pulling 100 watts.... What I did was buy a few different inverters (60w, 150 w, 300w) and use the correct one based on the application. The 60w has no problems running the TV/DVD, even with the line loss, and it has less overhead loss than the other two bigger ones.....  Not sure if there is a better way, but this has definitely been working for me over the last 3 years.

You're right. Where I went to school the math worked out to 10 AMPs but after looking at it again it's closer to 1. It's a Vizio 32".

Thank you! I've been looking into the inverter part of the system. I plan on only running the TV and maybe a charger for the auger until i figure out a way to charge the auger right off of the DC current. So i'll probably borrow your strategy if you don't mind lol. What do you run for a battery bank on yours?

Looks like the majority of the Vizio 32" tv's are drawing 32 watts.... So, if you divide the volts into the watts it will give you the amps... (32w /12v=2.6677a) Then add 10% for inefficiencies of the inverter (2.6677a * 1.1 ) and that gives you 2.93 amps

It's a lot easier the way you're calculating it (aka the right way) lol. The one I have actually draws 22 amps so slightly less than your calculation, at 2.02. Looking at my math i was using 95Watts for some reason. Are your inverters pure sine wave or modified sine wave?

Pure sine inverters is the only way to go when working with electronics. I assume that you mean 22 watts, not amps. Usually if you can go to the manufacture site they will give you wattage for start up, typical usage, and stand by. I suggest using the middle ground between start up and typical for your figures and also suggest using an inverter 50% bigger than the application needs to account for line loss through the 120 AC wiring. I am using two 27 class deep cell 12v batteries, this is primarily because I use them in the boat for  the trolling motor. If you are looking at buying batteries specifically for this application, you are probably going to want to go with 6volt batteries instead because of the increase in Amp Hours and also the usable discharge on a multiple (2 or 4) 6v battery system is better than on a single or double 12 volt system.

Thanks, I am a homebrewer as well and going to add a nitro tap serving stout on the wall and put the keg in the closet at some point..  

 

Don't have to much and forget to take the keg out at the end of a weekend. Or you will come back to one big Beersicle!  :lol:

They are Gel Cells.  The long one is used for telecom backup power supplies.  I picked them up at Millaca Unclaimed Freight, they get random batteries once in a while.

    • Water that doesn't come out of a plastic bottle.
    • That's YOUR opinion.    Just remember, everything is fine, in moderation.
    • I do it, have experience with both homers and shooters. I am not a die hard as I was a few years ago but will get back into more when I get a new pup here in the near future.   The birds are not to bad to care for just need food and water. My experience and most troubles have been trying to keep critters out of the pigeon loft. Mink etc like to wreak havoc and it sucks when you lose all your birds to a stupid rodent. Especially the homers after you put in all the work to get them coming back. I haven't had any issues keeping birds at home by the dogs. Best part with the homers is if I train away from home, most times the birds are back home in the loft before I get back lol.   As for working the dog, you probably want to invest in a bird launcher as well especially since your dogs a pointer. Not sure how steady your dog will be or what kind of prey drive it will have. Hopefully you letting it chase birds already didnt cause any issues. I would just slowly introduce them to the pigeons. Might even start with just clipping some flight feathers and throw it in an open area and see how your dog reacts and go from there.   It should point naturally but just use the launcher to steady the dog up. Just look up methods with a check cord etc. when using the launcher. If you want them steady to flush or steady to shot that's up to you but that's way down the road yet. Some of that  pointing should come natural but with this dog being a little older you never know what your gonna get but never too late to start either I guess.    good luck

    • Not if you're diabetic.
    • Anyone here have any experience with keeping and using pigeons, especially homers, for dog training?   I have an almost 2 year old Brittany that has not even been out hunting yet.... Last fall he was pretty young yet plus I had some health issues that kept me unable to walk around the woods or fields.   I'm not trying to turn my dog into some kind of world champion hunter or anything. I just want to be able to spend more time, all year long as opposed to only hunting season,  doing the thing he loves to do the most. We already have a great time on a daily basis playing an endless game of fetch and he is the most prolific tennis ball catcher (after one bounce) that I have ever seen. He also spends his days chasing rabbits, birds and squirrels in our fenced in yard along with lounging in his very own pool on hot days. He is trained to do all the normal things like sit, lay, shake, come, etc and I have no doubt that he has lots of natural hunting instinct so this seems to be where the progression of his training should head.   I do live in town but as long as I'm not keeping dozens of birds at one time, I don't think it will be an issue. I will check with the city before proceeding though. I'm thinking of getting about 6 homing pigeon squeakers and keeping them in a hutch in my yard. Is there any problem with the birds being in the same yard as the dog?   I'm thinking I could go out to the country on any given day and plant a few birds for my dog to sniff out. I have access to private property to do this on but I am wondering, is it legal to do this on wildlife management areas? I think I recall that after a certain date it is OK to train dogs?   Anyone else do this? Any advice?
