If you are a traveler looking for a tiny house on wheels for camping, you might be wondering how to power your mobile tiny house. The logistics of living in a tiny house can be tricky especially when it comes to powering your tiny home.

In this post, we are going to help minimalists looking for off-grid solar systems for their tiny houses’ energy needs make virtuous decisions. Off-grid solar systems are gaining popularity over time because they are economical and environmentally friendly. This is mainly because they use solar energy during operation. In the end, you will have to cut your utility costs significantly.

The off-grid solar systems don’t require any electrical power grid connection. They only feature high capacity battery bank to hoard energy. This is the reason why many minimalists are in search of the best systems for sufficient energy supply in their homes.

We must admit that purchasing an off-grid solar system can be a daunting process especially if you don’t have enough information. So, it’s an ultimate task for you to check around for guides and reviews before making the decisions especially if you are a beginner. Besides the fact that there are many modules and guides online, very few of them are actionable. Check this tiny house off-grid solar system buyer guide and a list of top-rated off-grid solar systems.

Benefits of off-grid solar systems

The benefits of these solar systems are similar to the benefits you get when you install the solar panels on a larger apartment. The top benefit is that you will save money on energy bills. Secondly, you can protect the environment from the harmful effects of petroleum products. Tiny homeowners control their electricity generation.

In these situations, solar panel systems will help increase the value of your tiny house or RV in case you consider reselling it in the future. Most prospective buyers value-free and renewable energy which means they can pay more for these systems.

Many tiny houses are mobile meaning that you can move from one parking to the other. For people considering tiny houses on wheels, then solar energy is the best option because you will not have to waste time and money looking for electricity wherever you go. You automatically have a guaranteed source of energy.

What to consider when buying tiny house solar systems

In the efforts to minimize their energy usage and bills, homeowners are considering off-grid solar systems. Even though these solar systems seem easy to purchase, install and start using, there are countless tiny house solar considerations you should familiarize yourself with.

How much electricity do you need?

Tiny houses generally use less electricity. But the energy requirements can vary from one person to the other depending on the appliances in use and other factors. To maximize your savings without bargaining your utility, you automatically need to get the exact Kilowatts that you need for the appliances, lighting, and security systems. If you are not able to determine the amount of electricity needed in your tiny house, you can check the calculator on the Department of Energy Appliance and Home electronic use Control. You will just be expected to enter the appliances you have in your home and they can give an estimated amount of electricity you need.

Rooftop vs. Ground-mounted Solar systems

Before purchasing off-grid solar systems, you need to decide whether you need a rooftop or a ground-mounted system. You will have to determine whether your roof gets enough sunlight and the roof is advantageously sound to hold the panels and the racking equipment. This will be directly impacted by the way your roof was built. In some situations, the roof might not be strong enough for the solar panels. It might not be well placed to maximize the sunlight.

The alternative, in this case, is installing a ground-Mount system. But remember the ground-mounted systems will require additional racking and mounting equipment. The main advantage is the fact that you have the freedom of choosing the spot with maximum sunlight.

Grid vs. Battery Bank

You also need to ask yourself the question of whether your tiny house is connected to the grid or not. Some tiny house owners would want solar systems as an alternative source of electricity. If you are considering the two, you have to compare the benefits of grid vs. Battery Bank. For the house connected to the electricity line, the solar system will work in a similar way. However, this is not possible for minimalists with tiny houses on wheels. The grid will always make it impossible for you to travel from one place to the other. Depending on what you need and your lifestyle, you can make the decisions.

Different Options for your house

Depending on the amount of electricity your tiny house needs, you can pick different solar energy options. Today, there are many brands and companies producing different parts of a complete solar system. The most common today are the Reongy, Canadian Solar, and Grape Solar. Many of them offer batteries as solar kit while others will advise you to purchase the batteries separately. Take your time to weigh different options before making the decision.

AC or DC

I bet you have already read about DC (Direct Current) being the most efficient type of power. Everything in the traditional houses is wired in AC (Alternating Current). This means that when you are putting your Solar, you should think about the best option for your needs and preferences. Solar Panels produce DC power and you are left to decide how to go about it. This will definitely determine the type of inverter you need in your kit.

Battery storage and solar panels

Depending on the amount of electricity you need in your tiny house, you can define the amount of storage and the number of solar panels for the house. The Solar panel power the solar generator, consequently, having ample solar PV input allows you to generate more energy per day. Inverters will now convert the low volt DC to standard 120V AC power making it easy for you to use it.

DIY installation or Professional Installation

Perfect installation ensures safety and effectiveness. If you are a beginner in this industry, you might not have the skills and savoir-faire for the DIY kits. This inevitably means you will have to research for professional installation in your area. If you have the knowledge and want to save the installation costs, then choose solar companies with comprehensive and easy-to-follow user manuals.

Budget

As stated earlier, the market is flocking with innumerable solar panels, batteries, inverters, and fuse manufacturers all with different prices. The most expensive solar system doesn’t pledge its efficiency. That said, you have to research solar panels with the right features for your energy needs and within your budget.

5 common mistakes people make when purchasing Off-grid solar systems

There are numerous costly blunders you can make when switching to solar energy especially if you live in tiny houses. To make sure you are set, here is the list of the five most common mistakes that can be very costly to you.

Underestimating energy consumption

Most minimalists are not forthcoming with their energy requirements. Most of them are too focused in energy savings and will end up giving the minimal number possible when it comes to energy consumption. Before you purchase your solar system, understand that adding more panels in the future can be very expensive.

When you purchase the solar system for your RV and your Tiny house, the company expects that the electricity costs will go down by a certain number. Giving the wrong information about energy consumption will definitely spoil the game.

Only focusing on ROI

As a homeowner, or someone with a tiny kiosk, you definitely want to consider the ROI and there’s nothing wrong with that when it comes to the solar system. A home is actually a future investment and the value of your tiny house will significantly rise after installing the solar. But one mistake we all make is only considering the ROI and ignoring everything else that can make a difference. Take time to conduct research and sit down with the installer because there are different aspects of the solar systems.

Ignoring the various solar loan programs

You unquestionably don’t have to pay for the full amount because there are a couple of solar loan programs in the US. However, we all make the mistake of ignoring the various solar loan programs. Before purchasing the solar, understand the best matches for your needs and situations. Statistics from US Solar Market Insight Association, a single family residential home solar system can cost anywhere from $15,000 to $29,000. Most companies will not explain into details the different programs that can help you purchase the solar systems. They also don’t explain the process of transferring the solar agreement. Take your time to research and always ask questions.

Permitting and inspections

There are different permitting and inspections parities that you should acquaint yourself with depending on where you come from. It is also important to know the parts of your home that may be unpermitted. The permitting rules will vary from one place to the other, take your time.

Misunderstanding the roof installations

One of the most popular misconceptions is that installing the solar panels in the roof should face certain directions typically north to catch the sun. This couldn’t be wrong but you should know that the most important thing in solar energy is the sun light and not heat from the sun. DIYers should always ask enough questions from the supplying company.

The list of mistakes to avoid when installing off-grid solar systems is unlimited. Keep on researching to minimize the chances of making these mistakes.

Types of Solar for tiny house

There are three main types of solar panels for tiny houses. The one you will pick will mainly depend on the type of your tiny house and your energy requirements. Here are the three types that you can pick for your tiny house.

Grid-tied Systems

These are the basic solar systems that are standard grid-tied inverter. They lack the battery storage which is perfect for customers complimenting their electricity source. They are very simple to design and they are also very cost effective. The only challenge is that when the system goes off, so the supply.

Grid-Hybrid system

This is a simple solar panel type. It’s actually a grid-tied system with backup battery. It is ideal for customers that are already on the grid and just wants extra energy storage. It’s perfect for tiny houses on foundation and people living in areas where they are prone to outages. The main advantage is that you will get the best of both worlds.

Off-Grid System

If you have an RV or a tiny house on wheels, the off-grid solar systems are the best alternatives for you. It’s the best for people that want to cut the cost of bringing power to their place or those that wants reliable source of energy. This post is mainly focused on off-grid systems.

What parts do you need for complete tiny house solar set up?

Solar Panels

Solar panels convert sunlight into energy that is eventually transformed into electricity. In most instances, the average solar panel will produce about 300 watts per hour

Charge controller

The solar controller sits between the batteries and the panel. The panels channel the energy through the charger controller whose main aim is to ensure steady flow of energy to the batteries. The other importance is to prevent the risk of overcharge.

Battery Bank

The battery bank is where the solar panel-generated electricity is stored. The more batteries you have in this instance the more electricity you can store.

Inverter

You need inverters to start using Off-grid solar systems. In most instances, the electricity generated by this will need to be converted from DC to AC. This is the work of the inverter. However, most people claims that the Inverters can be noisy because of the cooling fan which is the reason why they shouldn’t be placed next to the sleeping area.

Battery Monitor

In most digital systems, this is an electric window where you can see everything from the level of charging to the condition of the batteries.

Tiny House solar Power system: Hire a Professional or DIY?

You might now be ready to get the solar system. But there’s one thing left which is to make the decision on whether you need professional installation services or whether you already have your own DIY skills that can save you the service fees. If this is your first time installing solar and you lack the necessary information and skills, you shouldn’t risk. You are definitely not confident enough to follow the instructions in the manual and install the kit. You also don’t have to risk damaging equipment worth thousands of bucks.

But I personally understand that most people get into tiny living because they want to live independently and be self-sufficient. For that reason, you might have thought about taking the challenge of installing the solar kit on your own. If this is you, then purchase tiny house solar system from consumer-friendly off-grid solar manufacturers. Most of them provide sufficient customer service and at the same time include a comprehensive manual with step-by-step guide on how to install the kit.

If you hit the wall, it’s always advisable to call a professional to help you complete the work. The advice is to always involve a professional because setting up the tiny house solar panel can be very intimidating. But as long as you believe in yourself and confident you can handle the whole work, try DIY Tiny house Solar systems.

How many solar panels does it take to power a tiny house?

If you have an average solar size of 300 watts generating about 4,500 watts of power from the sun, you typically need about 15 solar panels to power an average house. However, there are countless other things you should consider when determining the number of panels you need in your tiny house. In most instances, the types and the number of appliances you have in your tiny house will significantly alter the energy requirements in your house. Consequently, you might end up requiring more solar panels or less of them to meet the specific energy requirements.

How much does it cost to solar power a tiny house?

The amount of money you need to power a tiny house will depend on a number of factors. The first and the most significant factor is the energy requirement in your home. The energy requirement is directly proportional to the number of panels and the bank you need which will significantly affect the amount of money you will spend on the system.

There’s clearly no definite answer to the amount of money you are going to spend to power your tiny house. But there are some key factors that can help you along the way. Your decisions on the amount of money you need to power will depend on the type of solar systems you’ll buy. The market currently has countless types and brands of solar systems all at different prices.

In an average tiny house, you might end up paying more than $6,500 on average for the full off-grid solar Kit. This amount will significantly depend on the brand and the type of system you are investing in. You will also be required to pay $2,000-$5,000 for the installation, permits and the inspections. The upfront payment might also be overwhelming especially if you are in the US. But with the electricity costs still on the rise in the country, solar panels have higher long term benefits.

How do you put solar panels on a tiny house?

Calculate your energy needs

The first thing to do in this case is to calculate the energy requirement in your area. There are several ways you can calculate this especially if you don’t have insights about normal estimates. You can use a solar Calculator to determine your electric usage. The other alternative is to calculate your energy needs using the appliance chart. With these details, you might consider some energy efficient appliances for your tiny house to reduce the electricity costs.

Calculate the expected sun hours

Before heading to the market for an off-grid solar system, you should calculate the sun hours in your area. This is the case if you don’t intend to move around with your Tiny House RV. You should note that you are more likely to experience less sun in some seasons. Use the Sun chart to determine the amount of sun and the sun hours per season in your area.

Determine the best placement for the solar panels

As explained above, there are two major types of solar placement options which are the roof and ground placement. Before purchasing the solar, you should determine the best option for maximum sun exposure depending on where you are. You should use a tool called the ‘’solar path finder”. This is an actionable tool that can help you determine the best location and eventually snap a photo. The photo will be uploaded to the program and you will instantly get many calculations and guide.

Purchasing your solar System

With the details about the expected energy needs and the expected sun hours per season in your area, you now have to invest in a preferable solar system. This guide has explained the factors to consider when purchasing your solar system above. But we forgot to clarify the fact that the weight and the size of the solar are also impactful. Remember that the batteries, the panels and the inverters are bulky and heavy.

When shopping for your solar system, remember research is very imperative expressly because there are countless options and brands all with different prices. It’s also important to note that large companies are not always the best. Ask yourself these questions while on the market.

  • What are the equipment options?
  • What are the reviews of the specific solar company?
  • Should I go for professional installation or DIY options?
  • What is the size of the solar panel?

Build the battery and inverter cabinet

You are now expected to build a cabinet to house this equipment. Just like any other minimalist, you need a stand-alone space for the batteries mainly because they’re heavy. Note that the bottom and the top of the cabinet should be divided so that the gases from the batteries don’t spoil other equipment.

Wire the batteries

The batteries will be wired according to the instructions given by the company. If you have 6Volts batteries and you want to wire for 24 volts, you should wire in series parallel. Depending on your needs and preferences, you can choose a 24 or a 48 volt system. But besides the fact that the 48V option is more efficient, the 24 volts can future proof your setup.

Install the panels in your roof

The installation process can be daunting and this is why I recommend getting professional aid to install the panels in your roof. The number of panels installed will depend on your energy requirements.

Connect the panels directly to the inverter

It’s now time to connect the panels directly to the inverter depending on whether you need DC or AC options. You can as well connect the inverter to the battery and then to the power grid.

Inverter and the Batteries

You will install the wiring from the battery to the circuit breaker and the electrical shunt. But before this, you should connect the inverter to the battery. The circuit breaker lets the current break to avoid accidents and damages.

Connect to the AC Fuse in your house

It’s now time to connect the inverter to the AC fuse in your tiny house. The inverter has a couple of transformers and switches that convert DC and AC options. You should connect it to the AC fuse in the house as instructed in the manual.

Connect the AC generator to the power inverter

This will ensure that you are provided with additional electricity in case you run out of the battery power. Remember that the solar energy is very unpredictable.

Off-grid solar system for tiny houses-Tips and tricks

Statistics shows that more than 30% of electricity used on an average house is wasted. I bet one of the many reasons of considering the minimalist movement is to cut the costs of energy and reduce wastages. For that reason, utilize these Tiny House off-grid solar tips and tricks to prevent wastages and electric expenses.

Passive solar design techniques

It doesn’t matter whether you are considering getting a custom tiny house built for you or building your own house, it’s very important to consider passive solar design that relies on natural thermodynamics. This automatically means that your house will be heated in the winter season and remains cool naturally during the hot summer months.

Use a Programmable Thermostat

Heating and cooling using the electricity is very common with the minimalists. This is mainly because most minimalists want to live on the road and they don’t have an option for a woodstove. For that reason, you should have a programmable thermostat that can adjust the temperatures as needed. This way, you can save up to 15% on your energy needs.

Swap out your bulbs

It’s very clear that more than 20% of the energy produced by the solar system goes to lighting. For that reason, you should swap all your bulbs to LEDs that can save up to 75% of energy. The bulbs also last longer which saves you a lot of money overall.

Get energy Star appliances for your kitchen

The household refrigerator/Freezer combo consumes about the combined output of 25 large power plans every year in the US alone. If everybody turned to the energy-smart models, they can save on electricity significantly. Get energy-star washing machine, microwaves, dryers and Freezers.

Get a Laptop and not a Computer

The US Department of Energy claims that Americans loses about $100 every year because they accidentally left their computer on all day. To avoid draining your solar bank, its advisable to get a laptop.

Ask friends for solar recommendations

It’s advisable to always go with the recommendations especially when it comes to the manufacturers, brands, efficiency and durability of this equipment. The best tiny house solar buying tip is to always ask for experiences and reviews from friends, colleagues and neighbours.

The Manufacturer’s warranty

We usually forget to check the length of the manufacturer’s warranty. If the manufacturer is reputable, they are very likely to give longer warranties on different equipment and you can expect the equipment to last longer.

Check the solar panel certifications

This will be significant for panels that are attracted to the government rebate. In this case, the testing will indicate the type they have underwent such as the TUV IEC 61215. This certification confirms that the solar panel has undergone testing in 3rd party labs.
