Sunshine Measurement

Before you invest money in adding solar power to your garden shed you need to find out if it is viable. You need to know how much sunlight you’re getting on the roof.

A solar Pathfinder can help to determine if you are getting sufficient sunlight. Once you have determined that you’re getting enough direct light you can move on to purchasing the required equipment.

Wire Your Wooden Shed

The first thing you need to do is to wire your solar panel to the junction box in the shed. Make sure that your wiring is watertight.

Simply follow the wiring diagram you got with your solar charging kit to wire your junction box. Generally the red wire is connected to the positive terminal.

Installing The Solar Panel On The Roof

Prior to the solar panel being installed on your shed’s roof it needs to be mounted. The panel will have to be bolted across a frame which you should have gotten with the kit.

Once you’ve installed the mounting hardware you can then position the panel on the wooden shed’s roof. Use the supplied solar power instructions to bolt the panel to the roof of your shed.

Route The Wiring From The Solar Panel To The Junction Box

The wiring you run from the solar panel can be positioned under your shed’s overhang. Simply drill a hole through the wall directly into the building.

Then route the wire through the hole and secure with a few wire staples. Later block the hole with some silicone caulk.

Connect Your Battery To The Inverter

You will have to connect your battery to the inverter so that it charges the battery during the day. To wire the battery to the inverter you will need to use heavy duty no.1 cable.

Take a look at the inverter and simply match the terminals marked on it to the battery. The red wire is positive and the black is negative.

Once this is done just flip the switch of the inverter to test if you’ve wired your battery correctly. If wired correctly the inverter’s light should turn on.

You then have to connect the inverter to the junction box. Simply wire two additional heavy duty wires from the junction box to your inverter. Like the battery just match the terminals.

Mounting Fixtures To Your Wooden Garden Shed

Now you can start adding fixtures like a ceiling light to your shed. Use the wiring diagram that accompanies your kit to route the the wire to your lighting fixtures.

Again, make sure that your connections are tight and moisture proof. Depending on the size of the solar power panel and the inverter you should be able to add another 100 Watts of load.

This will allow you to power things like an additional light, fan, power tools, electric screw driver, and a pump.

    How do you set up your solar panel if you live in an area where there is snow during the winter (Montreal, Canada)
    Please advise
    Thank you

    • says


      Based on reviewing several websites in the Montreal area it looks like you would install your solar panel so it faces in the direction where it will receive the largest amount of sun. You should install a battery system that will store the energy for the days the suns does not shine to power the equipment in your shed.

    hi i have a south facing garden and want to install solar panels on my shed roof can you please explain will i need an inverter and a battery or could i use an inverter many thanks

    • says

      I believe you will need both an inverter and battery. The battery is for a charged backup when the sun is not charging the solar panel and during evening hours.

      Good Luck.

    I’m wanting to connect power my metal storage building. I would like to be able to run a window ac unit in it. would this be efficient enough to do so?

      You can ad power to a metal storage building. Check you local electrical codes to make sure everything is safe to go. After installing the power you are ready to install the window AC unit.

    Looking for some quick advice. I’d like to run a solar power system in my shed. I am wondering how/where in the steps above to make a change to run standard electrical outlets and lights. I do not plan to overload the system, but would like to use conventional household wiring, lighting fixtures, and outlets. I plan to run 2 or 3 deep cell batteries, How do i then go from the inverter to 12g 2 wire? do i need a different inverter? an additional piece of equipment? Any help you can give me would be great! Thanks!

    I want to power a 10×10 shed with a small air conditioning unit and a light. Can I do that with a solar panel, and if so what do i need to do to have that electricity at night?


    • says


      The way I understand solar systems is that your solar panel will charge a bank of batteries that will provide the power at night to run the air conditioner. The solar system you install has to have enough batteries charged to run your shed air conditioner.

      Good Luck,
