Table: Daily Average Solar Panel Output By States In The Us
Assuming you are in Florida, the global horizontal irradiation is 5.079. So during peak hours, a 300 solar panel will generate 1.52kWh/day.
To get how many solar panels you need, divide your estimated power need by this figure 1.52kWh/day.
Then multiply what you get by 300 for total solar production in a day.
Australia is in the southern hemisphere, meaning optimal solar power is achieved when panels face north. Different states, however, have varied solar outputs.
Source: Clean Energy Council Consumer Guide page 4
The tabulation shows how much solar output your panels may produce daily in Australia. With total power consumption, you can use this to get the number of solar panels for your tiny home.
Other factors in solar production are battery amperage, the panels’ and batteries’ series or parallel connection, and inverter size.
Mounting Solar Panels On A Tiny House Roof
Many people want solar panels on the roof of their tiny house, but I opted for a ground mounted solar array, which I highly recommend. Tiny house roofs only have around 200 square feet of space and since most roofs are pitched, you can really only mount panels on one side. This means you only have around 100 square feet of space for panels.
What I did was mount my solar panels on stands on the ground. After considering all the options: roof mounted, pole mounted, solar trackers, and fixed ground mount, Im really happy with my decision.
The benefits of a ground mounted array are huge: being able to easily clean my panels, clear off snow that covers my panels after a snow fall, keeping the panels cooler and being able to shade my house while placing the panels in an open field.
The biggest benefit of ground mounting my panels is that I could have a way bigger solar panel array. This meant instead of 600 watts on the roof of my tiny house, I could put 4,000 watts on the ground in the field right next to my tiny house.

Solar Panel Mounting Options For Your Tiny House
You have a variety of options for mounting your panels:
- Ground mounting
When possible, you may want to use racks that allow panels to swivel. That way, as the sun crosses the sky, you can angle the panels to pick up more power.
While roof mounting can be a great option in some situations, you should think seriously about racks on the ground. They keep your solar panels readily accessible for cleaning or maintenance.
Roof mounting also confines you to the limited space your roof has to offer, whereas with ground mounting, you can use more panels and generate more power.
Plus, it tends to be cooler close to the ground, which is conducive for solar panel efficiency.
How Many Batteries Will I Need
Battery storage allows for Solar Power generated in the day to be used at night.
We build allowance for this is for when your system will be generating at its peak and for days of inclement weather where little to no solar generation occurs.
The more days allowed for means the less chance of having to charge the batteries from a generator. You can find more about our battery manufacturers here.

Pro #: Solar Panels Will Slash Your Electric Bills
The ability of solar panels to reduce electric bills is the #1 reason that American homeowners choose to go solar. Tiny houses already have lower utility bills, but by installing solar panels its possible to eliminate most, or even all, of your electricity charges.
A small solar system between 1 kilowatt and 3 kilowatts in size – enough to cover the needs of pretty much any tiny home – will result in average savings of between $250 and $750 annually.
Your exact savings figure will depend on several factors – weve listed the most important ones below:
Factors that increase solar savings:
- High energy usage
- Taking advantage of net metering
Factors that reduce solar savings:
- Cheap grid electricity
- Poor access to sunlight
- Lack of incentives from your state and utility
To see how all of these factors will play out for your particular home, enter your address into our solar calculator here.
Temporary Power Connections 50 Amp Plug
This is my preferred method and how I power my tiny house. I use a 50-amp plug from an RV supply store for about $30, plus an extension cord that I assembled myself by purchasing the ends and wire. The wire for a 50-amp drop cord is pretty pricey $3 a foot if pre-made or $1.50 per foot if you do it yourself.
Essentially, this is just a giant outlet that pumps a lot of power through it. Ive found with my local code enforcement that if I use this approach, it being temporary is a critical factor in being legal.
If my tiny house was hard wired, that would open up a huge can of worms legally speaking. Being that it is temporary by nature of the plug, building inspectors instantly lost interest, which is exactly what I wanted.The other benefit of this approach is that you can roll into almost any RV park and plug in, which makes this a win-win in my book.

Can I Run My House On Solar Power Only
There is a way to run a house on solarpower alone. It takes a considerable amount of time and money to go completely off-grid. The longer it takes to install solarpanels, the higher your energy requirements will be. If you are looking for a home that can be run entirely on renewable energy, look no further than a solarpowered home.
Youll Have To Clean Your Solar Panels Regularly
You cant relax once youve set up your solar power system. Youll also need to maintain it, mostly by keep your solar panels clean.
You know how annoying it is when birds do their business on your car? Theyre now going to be doing it on your solar panels. Snow, branches, twigs, and other random bits and pieces will all build up on there too, so youll need to make cleaning a regular activity. Are you prepared to wake up to no electricity on a snowy morning and have to head outside to clear it first thing?
The other thing to bear in mind here is the position of your solar panels. If theyre on the ground, cleaning them shouldnt be too difficult. But if theyre on your roof, youll have to climb up onto it. Now imagine doing that when its covered in snow and ice

Using A Backup Generator
The other component of this system is the generator which I used for the first two years and then opted to upgrade my system because they were such a pain to use. In the winter months, I sometimes needed to top off my batteries every now and then, basically when its been really cold and very cloudy for a week or more.
I had a Honda EB2000i already which I really like. Its very quiet and small. The one downside to the Honda is that it only does 1600 watts and only 120V and I needed more power and 240V. To charge my batteries, I had to have 240 Volts, which lead me to get another generator, a 5500 watt 240 volt Generac for $650. This generator proved to be a major headache and lead me to upgrade my system just to not have to use it anymore.
Here is a video that compares the two generators in terms of size, noise, output, and price.
How Much Electricity Do You Want To Generate
In general, tiny houses use much less electricity than the average home. However, every tiny house is different, and how much electricity you use to power your tiny home will depend on its size, how many people live in it, the appliances you use, and more. To maximize your savings, youll want to aim to generate as much of your overall electricity needs as possible. This may mean only installing five solar panels or installing 15 of them.
If you dont know how much electricity your tiny house will use, the Department of Energys Appliance and Home Electronic Energy Use Calculator is a good place to start. You can enter individual appliances, along with how often you use them, to get an estimate of the amount of electricity they use per year.

Solar Panels Installation Costs Varies By Provider But Its Generally Around The Same Cost Here Is The General Cost You Can Expect For Going Solar
Almost half of American homeowners say theyve considered installing solar panels. Its an excellent option for tiny house homeowners.
You might be looking to get off the grid or reduce your carbon footprint even more. Solar panels can help you do it. One question you and many homeowners have is about solar panels installation costs.
How much is going greener going to run you?
This guide will give you a good idea of what it will cost.
The Cost Of Installing Solar Panels On Your Tiny House
Once you have figured out the number of solar panels required to power your tiny home and life, the next consideration is to calculate costs.
Solar energy companies offer a variety of solar energy options for tiny homeowners. Small solar panel systems cost as low as $6500 while larger installations cost upwards of $20,000.
The total costs of your solar power system depend not only on how many solar panels you require but also the battery and inverter requirements.

Install A Greywater System
I have also become an avid greywater recycler throughout my journey with sustainable living. In a nutshell, using a greywater system basically means recycling water that has already been used in places like laundry, shower, or sink, and repurposing that water for uses like irrigation and watering gardens and crops.
Greywater is different from blackwater or sewage because it isnt toxic and can be repurposed without contaminants. There are many different methods that greywater users adopt to make the process happen like installing pipes or using a rainwater catchment system.
Choose Your Racking System
Positioning your solar panels to face the sun allows you to maximize the amount of energy captured. You can choose to mount your panels on the roof or on the ground. Roof-penetrating racks are drilled into a roof with screw holes on their surface, so the panels can easily attach to them.
Most tiny homes have limited space on their roof, so it might be better to ground mount your panels. There are many ground mount systems that accommodate a wide range of sizes and panels. Some racking systems, such as pole mounts, allow you to adjust the panels angle. You can secure the panels onto the racking equipment using clamps or connectors.

How To Power A Tiny Solar House Off
If you are looking to power a tiny solar house off-grid, the first step is to install a solar panel system. The size and type of solar panel system you need will depend on the size of your solar house and how much power you need to run it. Smaller panels may be enough to power a tiny solar house, while a larger system may be needed for a larger home.
Is Solar Practical For Tiny Houses
In general, I think for tiny houses in one spot, solar is very realistic. Even if you dont start out on solar, the cost savings of living in a tiny house can let you save up for the install pretty quickly. When I rented an apartment, I was paying $1500 a month, compared to my tiny house that costs me about $15 a month . Living in a tiny house allowed me to save a ton of money while having a comfortable home.
So thats the surface level details of the system, Im going to be doing something in the future which will be a how to size, choose parts, hook up and all the other details of doing solar for your tiny house.

Pro #: Solar Power Offers Clean Renewable Energy
Another priority for tiny homeowners is minimizing their impact on the environment, and solar panels are the easiest way to achieve this.
Solar panels provide clean energy: they are completely emissions-free, meaning that they can substantially reduce your overall carbon footprint. The power they produce is also renewable – the sun shines anew every day, and no resources are consumed when we harness its rays.
Its also worth noting here that solar panels are the only practical option when it comes to using renewable energy in a tiny house. Solar panels are relatively cheap and usable pretty much anywhere, unlike other renewable options like wind power and hydroelectricity, which have high upfront costs and can only be installed in specific locations.
While some critics point to the use of resources involved in the production of solar panels – the footprint of carbon – research has shown this to be minuscule in comparison with emissions that solar panels help avoid.
Breakers Fuses And Disconnects
This one will be highly subjective to your design and how much additional protection you want to build in.
However, there are a few components that you should always use to protect your investment. These include:
- Low Voltage Disconnect
- Disconnect Switches
In-line fuses should go between the solar panels and the charge controller, the charge controller and the batteries, and the batteries and the inverter.
These allow you to protect the different components of your system from a short or overload that takes out one part of the system.
The fuse you place in them will vary based on the size of your solar system and how much power each line is carrying.
The disconnect switches should go in the same places so you have the option to totally power down the system for maintenance.
Make sure you follow the proper shut down sequencing.
Start by disconnecting the solar panels from the charge controller, then the batteries from the inverter, and then the charge controller from the batteries.
The low voltage disconnect goes between the inverter and the batteries. It prevents the inverter from over-discharging the batteries if you go too long without sun.
All of these systems should be connected on the positive cable.

There’s More To Solar Power Than Most People Think
When most people think about solar energy, they think of the inverter. But there’s a lot more to it than that. You’ll also need a charge controller, battery cables, and so on.
You’ll also need to really know what you’re doing to put everything together. Using Chris and Malissa as an example again, they got a lot of help from both businesses and people they knew.
Whidbey Sun & Wind helped them order the different components, helped them figure out how many panels and batteries they’d need, and supported them over the phone. Chris’ father used to be an electrician’s apprentice, and so helped them with the wiring. And their landowner is an electrician, so he walked them through things too.
If you don’t have friends who have experience with solar energy, you’ll probably need to hire an expert to help you. Electricity is dangerous stuff, so you don’t want to go wrong. Don’t go into this thinking it’s easy and that it’s just a case of figuring it out. Have a pro to hand.
