Mobile Solar SolMan

Adding Solar to your tiny house can be a daunting task if you are not up to date on all the latest technology and how it works together. 082

A couple of weeks ago we had a "Meeting of the Tiny Minds" and Bill Kastrinos of Tortoise Shell Homes told Stephen, Michael and I about this great solar solution that was out there.

What if there was a simple solution to this and all you had to do was plug and play? SoleMan a company based in Willits, California has come up with just that kind of solution.

They call their system the "one small, easy to move, all in one integrated unit, ready to point towards the sun at your best location, and deliver up to 1200 watts of AC power, and 12 volts DC power, and even charge all your Ni-Mh smaller batteries."

This little unit is on heavy duty bicycle wheels so you can have your Tumbleweed home in the shade and easily roll your solar unit where it gets the most sun.

The cool thing about the SolMan is that if your needs grow, so can the SoleMan. You can add another solar panel easily and even a third. The second one sits on it is own stand and can be adjusted as needed. If you chose to get a third panel they have a bracket that attaches all three together that can be folded up for moving. No need to deal with big panels and connecting them to your roof and knowing you have to park your home in the sun to get the most voltage to your system. Here are list of the SolMan features:

  1. Silent Operation: No sound whatsoever. Won't bother your neighbors or you with gas generator noise.
  2. Clean Operation: No gas needed, no gas cans to transport, no fumes or exhaust to worry about.
  3. No additional costs EVER! : Once you buy a Solman, it doesn't cost anything else to run, as long as you can point it towards the sun.
  4. No recurring gasoline costs, that are only going to go up, no oil changes, no short life span, as unit is designed to keep working for years. ( 20 year PV panel warranty)
  5. Completely self contained, integrated unit: Ready to go, plug and play green power. No engineering or electrical skills needed.
  6. Transportable: With ramps, the Solman can go with you in the back of a small van, SUV or truck. It can be laid horizontal safely.
  7. Mobility: 26 inch heavy duty aluminum spoke and rubber bike tires and perfect balance allow the unit to be wheeled to any location for the best sun, and can easily be turned thru the day for maximum solar tracking and optimal PV energy input.
  8. Deep Cycle Batteries: "2 or 3 -100 (200 to 300 amp-hr total) deep cycle sealed gel cell. No acid spills or venting. No maintenance.
  9. Enclosed battery Container: Optimizes battery life.
  10. Two 12 Volt Auto Plugs: Plenty of places to plug in your 12 volt accessories, lights, chargers, etc.
  11. One heavy 30 amp marine trolling motor plug on exterior, for water pumping, external battery charging, or additional external inverter.
  12. All external plugs have covers and are set up for outdoor use, even in the rain, and all critical components are inside and protected from the weather.
  13. Array only switch: to route unused, excess PV power during the day to external battery charging or water pumping.
  14. Blue Sky Solar Boost 2000E MPPT PV Charge Controller: can handle up to 25 amps or 3 PV panels, and Maximum Power Point Tracking gives additional 10% to 20% charging efficiency to PV input.
  15. 120 Volt Magnum MM-AE 1200 watt Inverter/Charger: this unit has a built in 70 amp charger for when your batteries are down, and you have access to a gas generator, or the grid, you can just plug in the unit and bring your battery bank up to full charge in as little as two hours, also has an AC transfer switch, that automatically senses external power and switches load to that when on.
  16. Magnum Inverter remote switch and status lights on back of unit.
  17. Fuse Protected: 150 amp inverter fuse, triplex plug 20 amp and exterior 30 amp plug.
  18. Heavy 15 amp solar PV-in plug, wired to solar controller for adding an external solar panels.
  19. Toe piece L on bottom, allows for easy transport of optional external PV panel.
  20. Solar PV panel hinged for easy access to internal box, and latches and locks if needed.

So if you are looking to take your tiny house off the grid and become independent and want to use solar as your main component this SolMan option is worth looking at. Of course there other other RV and home options so do your research and choose what is best for you and your situation. I just like the idea of plug and play and having everything put together where you need it and mobile to boot. by Kent Griswold

Living off the Grid

skystream

When we think of the term off the grid, we generally think of systems that provide electricity. However, many of these systems can do much more than that. For example, solar collectors can be used to heat water, which could be be transferred into heating your structure.

Wind power could be used to pump water. They also could be combined with other sources such as propane or wood to power a refrigerator or furnace.

You need to figure out which source of power is best for you or what combination will generate the most electricity for you.

Lets look at a basic set up and what you will need.

  1. A Generation Source: You will need either solar-electric panels or wind generators or maybe a combination of the two. Another idea could be water power. Your plan is to generate electricity.
  2. Energy Storage System: The most common way is deep cycle or golf cart batteries, which you connect to your system. The batteries store the energy you create for when there is no sun or wind to sustain your needs.
  3. Inverter: This is a devise that converts the 12, 24, or 36 volt DC coming from the batteries we discussed above so that they are usable with 110 or 120 AC needed with most standard appliances.
  4. Backup Generator: When natural conditions such as wind or sun fail you, you need a back up system to generate and charge your batteries. A generator of some type is needed for this. Some options include propane, diesel, or gas. These you would want to run during daylight hours so the noise does not bother your neighbors.
  5. Interface Connector: This devise is used so that you can be connected or disconnected with the grid. A lot of utilities will let you put the power you generate back onto the grid and thus reducing your grid costs.

It is recommended that you get work with professionals to get the best setup for your home. They can advise you on the best components and the correct amount you will need to meet your needs. So get to know your local alternate energy experts.

Often buying a complete system will save you money versus buying each part individually. Keep that in mind as you research your off grid needs.

Why Buy a Tiny House?

img_5380

Why would  you want to spend $15,000 to $50,000 on a small house when you could add a real addition to your house and have a permanent improvement built right on to your existing house? This article is assuming you are building a tiny house as an additional room along with your existing home. Here are a few suggestions that may also get you thinking of other  reasons this might apply for building that tiny house.  You can then decide what would work best for you and your circumstances.

  1. Permits Costs: The cost of a permit has grown by leaps and bounds over the past few years. I want to give you an idea what an average permit will cost you today. In most places in the U.S. they range from $15,000 to $50,000. Just to add another room or addition to your existing home. Remember that is just to get a permit to build your addition.
  2. Permits may not be available at all: Some towns, cities and counties no longer will issue a permit. You are banned from any new construction or additions in some areas of the country. This takes the ability to add to your home completely out of your hands. The answer is NO!
  3. Permit Time: Once a permit is requested it can take up to one to two years to process. If you need a space addition right away, it won't happen. It is necessary to plan way in advance and to know your needs are long before the construction can even start.
  4. Mobile: If you build a small house it can be moved when tenancy or purpose changes. It is not contained by a permanent foundation, but can be connected to a truck and towed to your new location and used again for the same purpose.
  5. Little Houses can be Sold Separately: When it comes time that you no longer need the additional space you can sell the little house separately from your real estate. It is easy to get back your investment, without completely selling your existing home to downsize. Or if you are living in this home and need to upsize because of additional family members, etc., you can sell it and migrate upwards.

These are five good reasons to buy a tiny house or space on wheels. Do you have other ideas or good reasons to do this? If so please use the comment section to give us your suggestions. by Kent Griswold (Tiny House Blog)

Tiny House Toilet Options

fencl-toilet

Three Issues to think about when choosing a Toilet

When looking for a toilet to fill your needs in a tiny house, these are three issues to think about before you make your final decision. There may be other issues, but this will give you a place to start.

  1. Industry Standards a toilet that can be easily replaced upgraded and repaired.
  2. RV Toilets that I have seen upon initial inspection look and feel inadequate.  That is, all of the ones I viewed at a local RV supply company mostly are plastic and don't give the design appearance that I would like to have in a bathroom fixture.  I have seen ones that have a ceramic bowl but with a plastic body/pedestal. If I may be subjective, They Are UGLY. I believe they include plastic due to the fact that if they were all ceramic that they would crack do to movement or deflection of the RV on the road and reduce weight. A very viable reason. Who wants to replace a toilet every time you move your RV. An option is to rough out the toilet drain stub-out 12" from the back wall instead of the 11" that RV toilets generally require so that way you have the option of installing a standard ceramic toilet or RV toilet. If an all Ceramic Toilet is used I would recommend that either you disassemble the Tank from the bowl during transport or provide some sort of Neoprene gasket to  separate the two similar materials. If the two ceramic parts rub aggressively they could very well cause breakage and failure. I have not had experience of being on the road with a two part ceramic toilet. I would recommend removing the toilet during transport to be on the safe side. I would be interested in hearing other peoples experience. A one piece all ceramic toilet is another option, but once again, if I may be subjective, They are UGLY. One option for a small space is the American Standard Cadet 3 round front bowl with a Tropic tank made for the Cadet bowl. The best thing is to look and see what is available in your area in a small size and choose what you like the best for your home.
  3. Price. The toilets that I have seen as stated above don't give offer the quality at the price points that I would like to see for myself. It is hard to justify spending more money on an RV toilet that is made of plastic. I have not done exhausted research on the RV toilets and I may be off base here. If there is a toilet that serves all of the benefits of durability during transport along with quality and pleasing appearance I would be more than willing to pay the extra cost.

cadet-compact

I believe that most tiny houses will be spending more time stationary than on the road and at this point merits a toilet that functions well in that context. I also believe in Composting toilets and that they can be as inexpensive and just as functional as standard flush toilets but they do require a level of responsibility to the user. This responsibility is a good thing. You can fashion a fully functional Sawdust toilet for as little as 10 dollars but this must be paired with a conscientious user. Local jurisdictions do play a part and most often side on the conservative for good reason. a good read on this topic is "The Humanure Handbook."

This should give you some food for thought when looking at options for a toilet in your tiny house that you choose to build. As always comments and suggestions are welcome.

When is a Building Permit Not Required?

lusby-porch

When is a building permit not required? How do I know what I can and cannot build? How do I find out this information?

This is a question I receive many times at the Tiny House Blog and I know it is something Tumbleweed home builders face when they make the decision to downsize to a Tumbleweed Tiny House.

First and most important thing to know is that each location is different, there are no set standards across the country so you need to check with your local County and City authorities. Thankfully much of this information is now online and you can do your research without talking to anyone.

I live in Sonoma County in Northern California. Here are the steps I went through to discover what the requirements were for building without a permit.

  1. I Googled "Sonoma County" and found their web site
  2. Than I did a searched on Permits on the Sonoma County website
  3. Clicked on Forms and Applications
  4. Found the form "When is a Building Permit Not Required?"

Not every county will be the same so this is just an example of how to start looking for the information. Here is the information I found doing this research:

WORK EXEMPT FROM A BUILDING PERMIT

The following is a list of work that may be performed without a building permit. If your project does notappear on this list of exempt work, you should assume that a building permit is required.

Note: Although some work is exempt from a building permit, additional permits or review may be required. Before a building or structure is erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished, it is important to contact the appropriate staff at the Permit and Resource Management Department (PRMD) to determine if any other permit or technical review is required.

Although work may be exempt from a building permit, it may be subject to other county regulations (Well and Septic, Zoning, Drainage, Sewer, etc.). Although a building permit is not required, the exempt construction/work must be code compliant. For example, re-striping a commercial parking lot is exempt from a building permit, however, the striping must conform to building code standards for accessibility and Zoning standards for parking lot design. Failure to comply with code requirements may constitute a violation.

Building:

  1. Accessory Structures: One-story detached accessory structures used as tool or storage sheds, playhouses or similar uses when located on a parcel which contains an existing single family dwelling or other permitted primary use or structure. Such structures shall not have a floor area that exceeds 120 square feet and the height above grade shall not exceed 12 feet. No more than one structure may be allowed under this exemption unless separated from another permit exempt structure by more than 50 feet.

Note: Electrical, plumbing, or mechanical work in connection with such structures requires an electrical, plumbing or mechanical permit even though a building permit is not required for the structure itself.

To read the complete document go to When is a Building Permit Not Required?

xsvh1

This document tells me that I can build up to a 120 square foot structure without a permit. It can't be higher than 12 feet and if I choose to put in electrical or plumbing I will need to get a permit for that only.

So technically I could build a Tumbleweed home that is less than 120 square feet on a foundation as long as it met these requirements. I would need a permit for the wiring and plumbing.

What if it is on wheels or considered an RV?

I was unable to find anything regarding this on the Sonoma County website. To my knowledge each town or neighborhood has its own rules regarding this. Some places allow you to park an RV at your home or on your property but only allow you to live in it for so much time and than you must move it. Others say it can only be parked but not lived in, and other areas don't care one way or the other.

What About a Remote Area?

Often you can build in a remote area without permits. Here again it is important to check with your county requirements.

Many people just build and some areas are so remote that no one knows about your cabin or home. If you are reported by neighbors or someone else you may have to deal with the local codes and/or remove or tear the structure down.

Hopefully this article has given you some idea as to where to start looking for this type of information and also what to look for. Comments and suggestions are appreciated.
