Most people compare wired and solar outdoor lights based on the sticker price. A set of six wired path lights might run $120 at the hardware store, while a similar solar set is $40. Easy choice, right?
Not so fast. The sticker price is maybe a third of the real story. Once you factor in installation, electricity, bulb replacements, and ongoing maintenance, the numbers shift pretty dramatically. Here is the honest math over five years — including the stuff solar lights do not do well, because pretending they are perfect does nobody any favors.
The Wired Lighting Breakdown
Let us assume a typical suburban yard: you want to light a 30-foot pathway, a small patio area, and a couple of accent spots near the garden. A standard wired setup for this might include a transformer, 8-12 low-voltage fixtures, and the cable to connect everything.
Equipment Cost
A decent low-voltage transformer runs $80-$150. Quality brass or aluminum path lights from a reputable brand cost $25-$50 each. Cable, wire connectors, and stakes add another $40-$70. For our hypothetical setup with 10 fixtures, you are looking at roughly $400-$650 just for the hardware.
Installation
Unless you are comfortable trenching cable, wiring a transformer to an outdoor GFCI outlet, and calculating voltage drop across a 50-foot run, you are hiring an electrician. Most licensed electricians charge $75-$150 per hour. A straightforward 10-fixture install typically takes 3-5 hours. Total: $500-$2,000 depending on your local rates and how complicated the layout is.
If you do it yourself and you know what you are doing, great — you save the labor cost. But if you do it yourself and do not know what you are doing, you might end up paying an electrician to fix your mistakes, which costs more than hiring one from the start. I have been there. Learn from my optimism.
Electricity
Low-voltage landscape lighting is not a huge power draw, but it adds up. A 150-watt transformer running 10 LED fixtures for 6 hours a night, 365 nights a year, at the US average of $0.15/kWh, works out to roughly $50 per year. Over five years, that is $250. If you are still running halogen bulbs (and a surprising number of older wired setups are), triple that number.
Bulb Replacements and Maintenance
LED bulbs in wired fixtures last longer than halogens, but they still fail — especially the outdoor-rated ones exposed to moisture and temperature swings. Budget $3-$8 per bulb, and plan on replacing 2-4 bulbs per year. That is roughly $15-$30 per year, or $75-$150 over five years. Add in the occasional corroded connector or chewed wire from a squirrel, and maintenance costs are real.
The Solar Lighting Breakdown
Same yard, same layout: 10 fixtures for the pathway and patio, plus maybe a string of overhead lights for the seating area.
Equipment Cost
Heoxo solar pathway lights run $29.99-$49.99 for multi-packs. A set of 8-10 lights plus a string of solar fairy lights lands around $60-$120 total. That is it. No transformer, no cable, no connectors.
Installation
Push stakes into the ground. Hang the string. Make sure the solar panels face south-ish. Done. $0 and about 20 minutes of your time.
Electricity
The sun does not send a bill. $0 per year.
Battery Replacements
Here is the honest part. The rechargeable lithium batteries in solar lights degrade over time. After 2-3 years of daily charge-discharge cycles, you will notice shorter runtime. Replacement batteries cost $2-$5 per light. Replacing batteries in 10 fixtures after year three: roughly $30-$50. Do it once in a five-year span, maybe twice if you are unlucky. Call it $100 max.
The 5-Year Total: Side by Side
| Cost Category | Wired Lighting | Solar Lighting |
|---|---|---|
| Equipment | $400 – $650 | $60 – $120 |
| Professional installation | $500 – $2,000 | $0 |
| 5-year electricity | $250 | $0 |
| 5-year bulbs & maintenance | $75 – $150 | $0 (bulbs not user-replaceable) |
| Battery replacements | $0 | $50 – $100 |
| 5-Year Total | $1,225 – $3,050 | $110 – $220 |
That is not a typo. Even the low-end wired estimate is more than five times the high-end solar estimate. And the high-end wired scenario — with a tricky install and a high-cost electrician — is nearly fourteen times the cost of solar.
What Solar Does Not Do Well (Let Us Be Real)
I am not going to pretend solar lights are a direct replacement for a professional wired system in every way. They are not. Here is where they fall short:
Brightness. Wired low-voltage lights with high-lumen LEDs can throw serious light. If you need to illuminate a 50-foot driveway for security purposes, wired wins. Solar lights are designed for accent, pathway, and ambient lighting — not floodlight-level brightness.
Winter performance. Shorter days and cloud cover mean less charge. In northern states during December and January, solar lights might run for 4-5 hours instead of the usual 8-10. Snow covering the panels is the real issue — you have to brush them off. Wired lights do not care about the weather.
Consistency across fixtures. In a wired system, every fixture gets the same voltage and every bulb puts out the same brightness. In a solar setup, a light in a shady spot will be dimmer and run shorter than one in full sun. Placement matters a lot.
Smart home integration. Most wired systems can integrate with timers, smart switches, and home automation. Solar lights with dusk-to-dawn sensors are automatic but dumb — they come on when it gets dark and turn off when the battery runs out. No scheduling, no app control.
Who Should Stick With Wired
If you need high-output security lighting, if you live in an area with very short winter days, or if smart home integration is non-negotiable for you, wired lighting still makes sense. The cost premium might be worth it for those specific use cases.
Who Should Switch to Solar
If your goal is pathway lighting, patio ambiance, garden accents, or general outdoor atmosphere — and you want to avoid writing a $1,500 check to an electrician — solar is the obvious play. The math is not even close.
One thing I have noticed after switching: there is a psychological benefit nobody talks about. When your lights cost nothing to run, you use them more. You leave them on every night. You do not think about the electricity meter. That sounds minor, but it changes how you experience your yard. Your outdoor space is lit and inviting by default, not by decision.
FAQ
Can I mix wired and solar lights in the same yard?
Absolutely. Many homeowners use wired floodlights for security near the garage and solar pathway and string lights for the garden and patio. They coexist fine — just make sure bright wired fixtures are not washing out the softer solar accent lighting nearby.
How much sun do solar lights actually need?
For full runtime (8-10 hours), the solar panel needs roughly 6-8 hours of direct sunlight. Partial shade reduces charge. A panel in full shade all day will still charge somewhat from ambient light, but runtime will be 2-3 hours at best.
Are solar lights really IP65 waterproof, or will they fail after one storm?
IP65 means protected against water jets from any direction — rain, sprinklers, and snow are all fine. They are not submersible (do not install them in a pond), but normal outdoor weather will not damage them. Heoxo lights are sealed against moisture ingress at every connection point.
What happens if I move — can I take solar lights with me?
Yes. This is a genuinely underrated advantage. You pull the stakes out of the ground and take them. Wired lighting is a permanent installation — you either leave it behind or pay to have it removed and the yard patched. Solar lights are your property, not the house’s.
