The tiny house movement has benefited a lot from the advancements in solar energy over the last decade. Solar power systems are more affordable and widely available for tiny homes, making it easier to generate practically free, clean energy.
Tiny houses that are always on the move or prefer to stay off the grid will also have a guaranteed, reliable power source even in the most remote areas. Tiny home owners can even jump on this renewable energy trend by assembling and installing solar-powered systems for their tiny houses themselves.
So what are the best DIY solar system kits available for tiny homes? Here are our top 8 solar system kit choices that are perfect for any tiny house:

Grid-Tied vs. Battery Bank: Which Is Better For Your House?
There are two types of solar power systems: grid-tied and off-grid. The difference between these two depends on where you store the energy you generate. Your solar panels only charge while there is sunlight, so you need to find a place to store the energy your house needs.
- Grid-tied: For grid-tied systems, the solar panels will send the energy you generate to the local utility grid. This becomes part of the power the people in your area use. In exchange, you get credit for the energy you generate. You can use as much energy as you contributed to the grid, so you have access to power when the sun goes down.
- Battery bank: On the other hand, an off-grid solar system will rely on a battery bank as their energy storage solution. Since you won't have any access to power lines, your batteries provide you the power you need throughout the day.
If you're unsure which system to use for your tiny house, consider your tiny house lifestyle. For homeowners living in remote areas, having your own power supply will ensure uninterrupted power consumption even if you live off the land for weeks at a time.
Alternatively, you can invest in a hybrid system so you can take advantage of both set-ups: you can connect to the grid whenever you’re in town, or rely on your batteries when it’s time to hit the road.

Should I Buy a Solar Energy Kit or Design My Own System?
Building your own tiny house solar collection system can be challenging, but it’s an undertaking any homeowner can successfully take on with the right research.
On top of finding the right panels and accessories, figuring out every appliance’s energy consumption, as well as your location’s optimal sun collection schedule are essential parts of the process. If you want to learn how to wire a tiny house for solar power from the very beginning, read our article here.
Here’s a quick way to decide whether to build your own system or buy a ready-to-install kit:
- Build your own system if you are planning a large-scale, more permanent harvesting solution
Solar panels are a reliable off-grid solution for tiny houses. Building a reliable off grid solar collection system requires painstaking attention to detail, but will reward you for years when done right. It’s a great way to passively harvest renewable energy for your home, whether or not you’re connected to the grid.
- Buy a kit if you know nothing about solar power systems and want a plug-and-play solution
If you're not too confident with building your tiny house’s solar power system, it's best to leave it to the professionals. Experienced solar manufacturers prepare everything you need to get renewable energy into your home. For infrequent travelers, buying a solar pack is a great way to supplement on-grid electricity and reduce energy costs or act as a reliable source during power interruptions.
How Many Solar Panels Should I Get For My House?
Tiny house owners are the perfect candidates for solar power use, since they don't need that much energy to run the appliances in their home. While traditional American houses use around 30 kW of energy every day, most tiny homes will only need around 3-4 kW daily.
If you're thinking about incorporating solar power into your tiny house, you will first need to study your power usage breakdown. Figure out how much energy you consume when powering the appliances and gadgets around your house, then include a buffer of 20% in your computations to account for cloudy days.
For tiny homes that only need 4 kWs, five solar panels should be enough. Make sure that you have solar panels of a uniform size, otherwise you will get different quantities of electricity at varying rates - which won't be good for the solar system energizing your house.
