If you rent your apartment, you have probably looked into solar energy at least once and walked away discouraged. Traditional solar requires roof access, professional installation, electrical permits, and a landlord who is willing to let you modify the property. For most renters, that list of requirements ends the conversation before it starts.
But there is a category of solar products built specifically for people in your situation. Plug-in solar kits are self-contained systems that generate electricity from sunlight without any permanent installation. You set them up on a balcony, patio, or near a window. You plug them in or connect your devices. And when you move, you take everything with you.
This guide will help you understand what these kits are, what to look for when shopping, and which type of system makes the most sense for your apartment and your goals.
What Is a Plug-In Solar Kit?
A plug-in solar kit is a compact, portable solar power system designed to work without professional installation or modifications to your home. A typical kit includes one or more solar panels, an inverter or charge controller, the necessary cables, and sometimes an integrated battery or smart meter.
The difference between a plug-in kit and traditional rooftop solar is significant. Traditional systems are permanent. They are bolted to your roof, wired into your electrical panel, and connected to the utility grid through a formal interconnection agreement. They require permits, inspections, and often tens of thousands of dollars.
A plug-in solar kit requires none of that. You unbox it, position the panels where they get sunlight, and either plug the system into a wall outlet or connect your devices directly. The entire setup process takes minutes, not days. And because these systems are designed to be portable, they are ideal for renters who may move every year or two.
What to Look for in a Solar Kit
Not all plug-in solar kits are created equal. Before you buy, there are a few key factors worth evaluating.
Ease of Setup
The whole point of a plug-in system is simplicity. Look for kits that require no tools, no drilling, and no electrical knowledge. The best systems are genuinely plug-and-play.
Portability
As a renter, portability matters. Consider the weight of the panels, whether they fold or break down for transport, and how easily the entire system can be moved from one apartment to another. A system that is difficult to relocate defeats the purpose of choosing a portable kit in the first place.
Power Output
Solar kits for apartments typically range from 800 watts to 2,000 watts. The right output depends on what you want to power and how much of your electricity bill you want to offset. It is best to take a look at your power bill and do a quick calculation based on your consumption. If you need help with this process, we are here to help.

Battery Compatibility
Some kits include an integrated battery. Others are designed to work with the grid through a smart meter. And some offer both options. If backup power during outages matters to you, make sure the kit either includes a battery or is compatible with one. If your main goal is reducing your electricity bill, a smart meter system that feeds solar power directly into your apartment circuit may be the better and more affordable choice.
Safety Features
Look for systems with UL certification or equivalent safety ratings. If the kit plugs into a wall outlet, it should include anti-islanding protection and, ideally, a smart meter that prevents the system from backfeeding excess power into the grid. These features are what make plug-in solar kits safe and legal to use anywhere in the United States.
Best Plug-In Solar Kits for Apartments
Rather than recommending specific brands in isolation, it helps to understand the size categories of kits available and which one fits your situation. Apartment-friendly plug-in solar kits come in many sizes. Each includes a smart power meter that monitors your home's real-time energy consumption and prevents the system from backfeeding power into the grid, which is what makes these kits legal to use in all fifty states.
One important note about setup: while the panels and inverters are true plug-and-play, the smart power meter requires installation inside your electrical breaker box. This involves clamping current transformer sensors around the main wires in your panel. Craftstrom recommends hiring a licensed electrician for this step, which typically takes under an hour. Once the power meter is in place, everything else plugs into standard outlets. The meter is also portable and moves with you when you change apartments.
800-Watt Kits (The Starting Point)
An 800-watt system is the ideal entry point for renters who want to start saving on electricity without a large upfront investment. These kits typically include four solar panels, two smart inverters, and a smart power meter. With five hours of good sunlight, an 800-watt system produces roughly 4 kilowatt-hours of energy per day.
That is enough to cover your always-on loads like your refrigerator, Wi-Fi router, and phantom draws from standby devices, with energy left over for everyday electronics like a laptop, phone charging, and LED lighting. For a renter in a small apartment without heavy daytime energy use, an 800-watt kit can offset a significant portion of your electric bill. It is also the most space-efficient option, fitting comfortably on a standard apartment balcony.
1,200-Watt Kits (The Sweet Spot)
A 1,200-watt system is the sweet spot for most renters. With five hours of sunlight, it produces roughly 6 kilowatt-hours per day, which is enough to cover most or all of your non-AC daytime loads. That means your refrigerator, router, lighting, laptop, television, and other daily-use electronics can run largely on solar during daylight hours.
This is the size we recommend most often. It offers the best balance between cost, space, and real-world savings. If you have a south-facing balcony or patio with decent sun exposure, a 1,200-watt kit will make a noticeable difference on your monthly bill from day one.
1,600-Watt Kits (For Higher Usage Homes)
A 1,600-watt system is the right choice if your household runs more devices during the day or if you want to offset some of your air conditioning load during warmer months. Producing roughly 8 kilowatt-hours per day with good sunlight, this size can handle your always-on loads, your everyday electronics, and additional draws like a desktop computer setup, a window AC unit running part of the day, or a washing machine cycle.
This kit requires more panel space than the 800 or 1,200-watt options, so it works best if you have a larger balcony, a patio, or a ground-level outdoor area where you can spread out the panels. If your electric bill is consistently high during summer months, the 1,600-watt system delivers enough output to make a serious dent.
2,000-Watt Kits (Maximum Offset)
A 2,000-watt system is the largest apartment-friendly kit and the best option for renters who want to maximize their electricity savings. With five hours of sunlight, it produces roughly 10 kilowatt-hours per day. That is enough to cover virtually all of your daytime electricity consumption in a typical home, including moderate air conditioning use.
At this size, you are offsetting the majority of what you would otherwise buy from the grid during daylight hours. The tradeoff is space. A 2,000-watt system requires ten panels, so you will need a large balcony, a rooftop area, or a patio with ample room. But if you have the space and want the biggest possible reduction in your electricity bill, this is the kit to choose.

What Can These Systems Power?
Setting realistic expectations is important. A plug-in solar kit for an apartment is not going to replace your entire utility connection. But once you see how much energy your household actually uses during daylight hours, you might be surprised by how much a well-sized system can offset.
Here is a breakdown of common household devices and appliances, what they typically draw in watts, and how that adds up during a normal daytime period.
Always-On Devices (Running All Day)
Your refrigerator or fridge-freezer is one of the biggest constant loads in any home. While it is rated for 100 to 400 watts depending on size and age, the compressor cycles on and off throughout the day, so real-world average draw is closer to 150 to 250 watts at any given time. A Wi-Fi router runs continuously and draws 5 to 20 watts. If you have a cable modem or mesh network system, add another 10 to 15 watts. A security camera system or smart home hub might add 10 to 30 watts. Devices on standby, including your TV, game console, microwave clock, phone chargers left plugged in, and other electronics, collectively draw 20 to 50 watts even when you are not actively using them. These phantom loads run all day and night.
Taken together, always-on loads in a typical home add up to roughly 200 to 350 watts at any given moment during the day.
Daytime Use Devices
A laptop on a charger draws 50 to 100 watts. A desktop computer with a monitor uses 150 to 300 watts. LED lighting across a few rooms runs 20 to 60 watts total. A television draws 50 to 200 watts depending on size and type. A ceiling fan uses 30 to 75 watts. A washing machine uses 350 to 500 watts per cycle, though you might only run one load during the day. A dishwasher draws 1,200 to 1,800 watts but typically runs for just one hour. A microwave pulls 800 to 1,200 watts but only for minutes at a time. A coffee maker uses 800 to 1,200 watts for about ten minutes in the morning.
Air Conditioning
If your home has air conditioning, this is your single biggest daytime energy consumer. A window AC unit draws 500 to 1,500 watts depending on size, with a typical bedroom unit running around 800 to 1,000 watts. A portable AC unit uses 900 to 1,400 watts. A central air system draws 3,000 to 5,000 watts but cycles on and off, averaging around 1,500 to 2,500 watts over a hot afternoon. During summer months, air conditioning alone can account for more than half of your daytime electricity use.
Putting It All Together
On a typical day without heavy AC use, a home might be drawing 300 to 600 watts on a rolling basis during daylight hours from always-on loads and normal device use. That translates to roughly 3 to 6 kilowatt-hours over a ten-hour daytime window. Add moderate air conditioning and that number jumps to 8 to 15 kilowatt-hours during the day.
This is why a 1,200-watt solar system hits the sweet spot for most households. With five hours of good sunlight, a 1,200-watt system produces roughly 6 kilowatt-hours of energy per day. That is enough to cover most or all of your non-AC daytime loads, and it puts a meaningful dent in your bill even on days when the air conditioning is running. For renters in apartments without central air, a 1,200-watt system can realistically offset the majority of your daytime electricity consumption.
Smaller systems still make a real difference. An 800-watt system producing around 4 kilowatt-hours per day can cover your always-on loads, your laptop, your lighting, and more. But if you want to maximize your savings and your apartment has the space, 1,200 watts is the target to aim for.
Setup Example: A Real Apartment Scenario
Here is what a typical plug-in solar setup looks like in practice.
You have a south-facing balcony on the third floor of your apartment building. You purchase an 800-watt balcony solar kit that includes panels, smart inverters, and a smart power meter. Before your panels arrive, you schedule a licensed electrician to install the power meter in your breaker box. The electrician opens your panel, clamps the current transformer sensors around your main wires, mounts the meter, and closes everything back up. The whole visit takes about thirty to forty-five minutes.
Once the power meter is in place, the rest is on you. On a Saturday morning, you unbox the panels, lean them against your balcony railing, and connect them to the smart inverters with the included cables. You plug the inverter into the outdoor outlet on your balcony. The power meter immediately begins communicating with the inverters through the Craftstrom app, and your system starts feeding solar power into your apartment's circuit. Your refrigerator, the lights in your kitchen, and the laptop on your desk are now partially running on sunlight. No permits were filed. No utility company was contacted. The only professional involvement was the brief electrician visit for the power meter.
When you move to a new apartment next year, the electrician removes the power meter in minutes, and you pack up the rest of the system yourself. At your new place, you schedule another quick install for the meter and set up the panels the same day.
Conclusion
Plug-in solar kits have made apartment solar practical, affordable, and genuinely accessible. You do not need to own your home. Apart from a brief electrician visit to install the smart power meter in your breaker box, the rest of the system is entirely in your hands. You just need a sunny spot and a system designed for the way renters actually live.
