The short answer: if you want decorative light on a gate post, pillar, or fence cap, solar is almost always the sensible choice. If you need bright, guaranteed, all-night illumination — security lighting, a long dark driveway, a post in permanent shade — hardwired is worth the trouble.
Both have real advantages. Here's an honest comparison so you can decide which one your situation actually calls for.
What "hardwired" actually involves
A mains-powered post light needs electricity brought to the post. In practice that usually means digging a trench from your house or an existing outdoor circuit, running rated outdoor cable through conduit, and having it connected by a qualified electrician. Depending on where you live, outdoor electrical work may also need a permit and inspection.
We're not electricians and requirements vary by state and municipality, so get a local quote and check your own code requirements before assuming it's straightforward. The cost is rarely the fixture — it's the labour and the digging.
There's also the matter of where the trench goes. A driveway pillar often sits on the far side of paving, a lawn, or a planted bed, and getting a cable there without tearing something up is frequently the sticking point.
What solar involves
You place the light on the post and screw the base down. That's the whole job. No cable, no trench, no electrician, no permit, and no addition to your electricity bill.
It also means you can change your mind. If you rebuild the fence, move a pillar, or decide the light looks better somewhere else, you unscrew it and move it.
Side by side
| Solar | Hardwired | |
|---|---|---|
| Installation | Minutes, no tools beyond a screwdriver | Trenching, cable, electrician |
| Running cost | None | Small but ongoing |
| Brightness | Ambient glow | As bright as you want |
| All-night operation | Depends on charge and season | Guaranteed |
| Works in deep shade | Poorly | Yes |
| Moveable later | Yes | No |
| Parts that wear out | Battery, eventually | Bulb or LED module |
Where hardwired genuinely wins
Brightness. A mains fixture can put out far more light than a solar one, because it isn't limited by what a small panel can gather in a day. If you need to actually illuminate a dark driveway rather than mark its edges, that matters.
Certainty. A hardwired light comes on every night at the same brightness regardless of weather. Solar output varies with the season and the sky.
Shade. If the post sits under a tree canopy or on the north side of a tall building, a solar fixture will struggle to charge and you'll be disappointed. No amount of good design fixes a panel that never sees the sun.
Solar's real limitation, stated plainly
Solar post lights are charged by daylight, so how long they stay lit depends on how much sun they got. In summer, with the panel in direct sun, you'll get a long evening. In midwinter, with short overcast days, the run will be shorter. That's true of every solar fixture on the market, whatever the marketing says.
Two things help. Place the light where it gets direct daytime sun rather than dappled shade. And use a timer if the fixture has one — setting a four-hour run after dusk spends a shorter winter charge on the hours you actually want light, instead of fading out at two in the morning when nobody is looking.
Batteries also degrade over years of charge cycles, as they do in any rechargeable device, and will eventually need replacing.
What about low-voltage systems?
Low-voltage landscape lighting sits between the two. A transformer plugs into an outdoor outlet and steps mains power down, then cable runs to the fixtures. It's less involved than full mains wiring and often doesn't need an electrician, but you're still burying cable and you still need an outlet within reach.
It's a good option if you're lighting a whole garden with many fixtures. For two lights on two gate posts, the effort rarely pays off.
Our take
We build solar post lights, so we're not neutral — but here's our actual reasoning. Decorative entrance lighting doesn't need floodlight output. It needs a warm glow that makes a gateway feel finished after dark. That's a job solar does well.
And the install barrier is the real reason most people never get around to lighting their gate posts at all. A quote for trenching turns a nice idea into a project. A light you screw down in five minutes doesn't.
If you want bright security lighting, buy hardwired and hire an electrician. If you want your entrance to look warm and considered at dusk, our solar pillar lights will do it this weekend.
Quick answers
Do solar post lights work in winter? Yes, but for shorter periods each night, because they have less daylight to charge from. A timer helps you concentrate that charge into the early evening.
Are solar lights bright enough to see by? For marking an entrance, a path edge, or a driveway boundary, yes. For lighting up an area like a floodlight would, no.
Do I need an electrician for solar? No. There's no mains connection at all.
Can I switch from hardwired to solar? Yes, provided the post top is flat and the base plate fits. Have any redundant wiring made safe by a qualified electrician. Our post size guide covers the measurements.
