It’s time to shed light on your backyard’s solar potential

Get quotes from up to 3 pros ! Enter a zip below and get matched to top-rated pros near you. Find pros Whether you use your backyard shed as a home office or gym—or keep it simple and use it for storage—you can harness the power of the sun with shed solar panels. Homeowners who install solar panels on a shed can generate renewable energy and reduce electricity bills. Here’s a guide for everything you need to know about installing solar panels on a shed, including how to DIY, the pros and cons, and how much it typically costs.

Is It Worth Putting Solar Panels on My Shed?

If you need electricity in your shed, be it for recharging batteries, plugging in tools, or simply giving yourself some light to work, installing solar panels can save money and help the environment. If you have a large shed with a sturdy roof, it's even possible to outfit it with enough panels to supply power to your main property.

Here’s what to consider before installing solar panels on your shed:

Your Shed’s Purpose

If you use your shed to house gym equipment, charge batteries, or plug in power tools, you'll need a fairly powerful system to cover the amount of electricity you use. Keep in mind that your lowered energy bills will offset your upfront solar installation cost. You should determine how much electricity you’ll need by figuring out how many watts and lumens you require. A 60-watt bulb emits around 750-850 lumens of light. Bring an extension cord to your shed to power a work light to figure out how many watts you need. If one bulb feels too dim, look into solar kits that offer more than 60 watts (or 850 lumens). Here are some common shed items and the wattage they require per hour:

Electric drill : 600 watts

Table saw : 1,800 watts

Electric leaf blower : 2,500 watts

Hedge trimmer : 250 watts

Modem : 20 watts

Coffee machine : 600 watts

Electric heater: 2,000 to 3,000 watts

Solar Panel Kits

Solar panel kits come with everything you need to install the panels and related equipment yourself. They help take the guesswork out when determining which parts will work together; it can otherwise be challenging to match collectors, charge controllers, and batteries. In general, kits range in cost from $100 (just enough power to light the shed) to over $3,000 (enough energy needed for tools or charging batteries), depending on your needs. Higher-end models will likely include:

Solar collector panel: These panels convert photons into electrical currents

Charge controller : This device monitors the current to prevent battery damage

Battery : Stores the DC electricity

Inverter : Transforms DC electricity into AC electricity

AC Outlet: Plug-in tools or other items that need recharging

Lights: DC LED lights offer illumination and conserve the DC electricity

Less expensive options may only come with a small solar collector panel and a light to illuminate your shed. These kits (around $100) will provide light for about one hour.

Your Shed’s Durability

Your shed's roof must be large enough and able to withstand the weight of the solar panels, especially if you require larger ones. A 250-watt panel weighs about 40 pounds and measures approximately 65 by 39 inches. Suppose your shed is old, or looks to have some roof damage. In that case, you should consider buying a new shed or repairing the roof before proceeding with a solar panel installation. FYI, your shed's roof isn't the only place you can install solar panels—you can look into ground mounts, carports, or solar pergolas and gazebos .

Hours of Sunlight

Time for a bit of math! If your shed needs 3,000 watts to function, a 250-watt panel can create up to 1,500 watts if there are six hours of sunlight. With a second panel, you’re up to 3,000. However, this assumes the panels are receiving 250 watts every hour—something that will likely only happen on days with idyllic, sunny weather. If you live in a place with less sunshine (Seattle, for instance), give yourself a buffer and install panels with 20% more wattage than you will need on average. For example, if you need those 3,000 watts, install two panels with 300 watts to provide 3,600 on those clear days. You might need to use a backup power source (such as a generator) on rainy or dark days.

Installation

Solar panel kits let homeowners go the DIY route and install panels themselves. If you opt to use a kit, be sure you're comfortable handling electrical work. If that's not your thing, consider hiring a solar contractor or an electrician specializing in solar work.

The more solar panels you need, the more expensive the upfront costs. DIY solar panels range greatly in price, from $100 (for 100 watts) to $20,000 (10,000 kilowatts). Hiring an electrician or solar panel contractor will cost approximately $1,000 per 2,000 kilowatts installed.
