A path light that quits in November. A floodlight you have to remember to switch on from the kitchen. Most outdoor lighting decisions come down to two competing wishes: set it and forget it, or get exactly the light you want, whenever you want it.
Solar and wired fixtures both put light on your yard after dark, but they get there in very different ways. Here's how they stack up on the things that matter when you're standing outside with a shovel in one hand and a fixture in the other.
How Each System Actually Works
A solar fixture is a small, self-contained power plant. The panel charges a battery during the day, a photocell or timer tells the light to come on at dusk, and the LED runs off stored energy until dawn or until the battery runs down. No wires, no switch, no connection to your house.
Wired fixtures come in two flavors. Low-voltage systems step 120-volt house current down to 12 volts through a transformer, then run power along buried cable to each light. Line-voltage systems tap straight into your home's electrical circuit, usually through a switch, timer, or photocell. Either way, power is constant and doesn't care whether it rained all week.
Cost: What You Pay Upfront and Later
Solar wins the opening round on price. A solar path light costs a fraction of its wired equivalent, and you install it yourself in a couple of minutes. No transformer, no cable, no electrician, no trench.
Wired costs more at the start, and line-voltage setups cost the most because they typically need a licensed electrician. In many areas that work also requires a permit and inspection, so check with your local building department before assuming you can do it yourself.
Then the math flips over time. Solar batteries are consumables. Good ones last several years; cheap ones may fade after two or three seasons, and some fixtures don't have replaceable batteries at all — you replace the whole light. Wired LED fixtures, by contrast, sip electricity and often run for years with nothing but an occasional bulb change. If you're lighting a large area, solar's low purchase price can disappear into a steady trickle of replacements.
Brightness and Light Quality
If you need serious illumination — a driveway, a back gate, a dark side yard — wired is the honest answer. Line voltage can drive floods and large wall lanterns without blinking. Low-voltage handles paths, garden beds, and architectural accents beautifully.
Solar output is limited by panel size and battery capacity. On a bright summer evening a good solar spotlight can be genuinely impressive. After three gray days in December, that same light may glow like a nightlight. Expect seasonal variation, and expect brightness to taper as the battery drains through the night.
Color temperature is the other quiet difference. Many budget solar lights skew cool and blue-white, which reads clinical against a brick wall. Warm-white options exist and are worth seeking out. Wired fixtures let you choose the bulb, so you can match the rest of your exterior lighting exactly.
Installation: Minutes vs. a Weekend
Solar installation is push-and-go, with one catch: placement. The panel needs direct sun for most of the day, which rules out the deep shade under your maple or the north side of the house. If a spot is dark and shaded, solar won't thrive there.
Low-voltage wired installation is a genuine project, but a manageable one. The rough sequence:
- Count your fixtures and add up their wattage, then choose a transformer with capacity to spare.
- Mount the transformer near a GFCI-protected outdoor outlet.
- Lay out the cable and fixtures loosely above ground, and connect everything to test it before you dig.
- Bury the cable 6 to 8 inches deep, deeper where anyone might dig or drive. Use conduit under paths and driveways.
- Keep connections above grade or inside sealed, watertight connectors — never a bare twist of wire.
- Add a drip loop at each fixture so water runs off the wire instead of into the joint.
- Test again, then backfill and tidy the cable.
Test the whole run on the grass before you bury anything. Chasing a bad connection through packed soil is a miserable way to spend a Saturday.
Before any trenching, call your local utility locating service — 811 in the United States — so nobody cuts a gas or irrigation line. And for line-voltage work, hire a licensed electrician. It's not a place to learn on the job.
Reliability Through Weather and Seasons
Wired lighting shrugs off rain, snow, and cloud cover. Its one vulnerability is a power outage, which takes your lights down with the rest of the house unless they're on a battery backup.
Solar is the opposite: independent of the grid, dependent on the sky. Long cloudy stretches, short winter days, snow sitting on a panel, and heavy leaf litter all chip away at performance. A solar light that runs twelve hours in July might manage five in January. That's not a defect — it's the physics of the system, and it's worth planning around if you live somewhere with real winters.
Maintenance Over the Years
Solar upkeep is simple but not zero. Wipe the panels a few times a season, brush off snow, keep shrubs from growing over them, and budget for battery replacement. When shopping, look for fixtures with user-replaceable batteries and a panel that can be angled toward the sun.
Wired systems need occasional attention too. Frost heave can loosen fixtures, plants swallow path lights, and connections corrode over time. But the parts are standard and repairable, and a well-installed low-voltage run can quietly do its job for a decade or more.
A Practical Way to Choose
Ask four questions before you buy anything: Does the spot get real sun? How bright does it truly need to be? Am I willing to dig, or hire someone who will? And how long do I plan to stay here?
Most yards end up with both, and that's usually the smart answer. Use solar for path accents, garden highlights, and any spot where running cable is impractical — it's also the obvious choice for renters and for lights you want working tonight. Use wired fixtures for security lighting, driveways, shaded beds, and anywhere you need full brightness every single night without thinking about it.
Start with the two or three places that bother you most after dark, solve those well, and let the rest of the yard follow. Good outdoor lighting isn't about one technology beating the other. It's about matching the right fixture to the right patch of ground.
