best solar kit for tiny house

Being a small homeowner, have you considered going solar, be it to reduce your energy bills or to enjoy freedom from the grid?

You may have moved into a smaller home to save yourself from the high upkeep that a large house demands. Even small homes need electricity for lighting, cooling/heating, and running appliances. You can go a step further to reduce your energy bills by meeting your energy needs with a home solar installation.

However, it is natural that you have doubts about its feasibility as a tiny house comes with a limited rooftop and yard. You would be happy to know that there are readymade solar panel kits specially designed for small home dwellers like yourself.

Read on to learn about the benefits of installing a small house solar system as well as tips and suggestions on how to find the right solar power kit for a tiny house.

Why should you install a tiny house solar kit?

The benefits of installing solar panels for small houses are somewhat the same as that for large ones. You can save money on energy bills, enjoy freedom from the grid, generate your own energy, and reduce your carbon footprint. 

A solar installation adds value to your property, irrespective of whether it is small or large. In the future, if you want to sell your home, having a solar system makes it easier and will fetch you a higher price. 

Most tiny homes are mobile. For small homes on wheels, solar power is the perfect solution, as you move from one place to another. This will eliminate the need to find a power source at each location, guaranteeing you power 24×7.

Before you go solar shopping, here are some questions for you to consider and find answers to.

Tips to buy small solar kits

What is your energy expectation?

If you are planning to go off the grid, you may have to consider your entire energy demand. If not, how much energy do you expect from the solar system?

Just because you live in a tiny home doesn’t mean your energy consumption will come down drastically. It depends on the devices and appliances you have and whether you are choosing ones with a high Energy Star rating. 

You can calculate your energy expectation from your past energy bills or by adding up the wattages of all electrical installations.

Do you want to stay connected to the grid?

This is a vital question. If you want to go off the grid, you should have a solar system big enough to meet all your energy demands, together with a solar battery for your nighttime needs. 

On the other hand, if you can continue to stay connected to the grid, you can eliminate the need for an expensive battery. Using a bidirectional meter, you can take advantage of the net-metering arrangement. This allows you to export excess energy generated during the day to the grid and draw energy from the grid whenever your solar system is falling short.

Where are you planning to install the solar panels?

The rooftop is a natural choice as it receives maximum sunlight. However, being a tiny house, the roof space may not be enough to accommodate all the solar panels. Moreover, if there are taller buildings or trees nearby, they may cast shadows on the roof, rendering them unsuitable for solar panels.

The next best option is your yard. If your tiny home is built on a large piece of land, you may consider the ground-mounted systems. 

Before choosing the placement for the solar panels, you need to ensure that the spot receives sunlight at least 5-6 hours a day. If you are choosing rooftop installation, you need to make sure that the roofs are strong enough to hold the weight of the panels. If you are in doubt, you can go in for the light-weight thin-film panels.
