Solar LED landscape lighting is a self-contained fixture system combining a monocrystalline solar panel, a lithium battery, and an LED module in one housing. In Oakland County, professional solar fixtures produce 50 to 150 lumens and run 3 to 8 hours nightly, depending on season. Solar makes sense when cable runs would be expensive or impossible: remote sign monuments, far driveway posts, detached outbuildings, and properties where trenching is blocked.
Where Solar LED Lighting Works Best
Solar is not a universal replacement for low-voltage wired landscape lighting. It is a specialty tool. We use it in five specific scenarios:
- Remote sign monuments. HOA entry signs 200+ feet from the nearest power source.
- Long driveways and gate areas. Rural Oakland County properties where trenching 400+ feet of cable is impractical.
- Detached outbuildings. Garden sheds, pool houses, and carriage houses without existing exterior power.
- Accent lighting on neighboring features. Lighting a tree or wall you cannot trench to without crossing a neighbor's property.
- Temporary or seasonal installs. Event venues, model home exteriors, and staging properties.
Where solar does not work: tree uplighting that needs 500+ lumens, facade wash on any building larger than a single-story cottage, and anything under dense tree cover that limits daily sun exposure below 5 hours.
What Separates Professional Solar from Hardware-Store Solar
The $15 solar path lights at the big-box store and the $250 commercial solar fixtures we install are not the same product. Five differences determine whether a fixture survives a Michigan winter:
| Spec | Hardware Store | Professional Grade |
|---|---|---|
| Solar panel | Amorphous or poly | Monocrystalline |
| Battery | NiMH, 500 to 800 mAh | LiFePO4, 20,000 to 80,000 mAh |
| Housing | Plastic or aluminum | Cast brass or bronze |
| LED | Non-replaceable | Replaceable module |
| Warranty | 90 days | 3 to 5 years |
Michigan Winter Performance
Oakland County averages 63 cloudy days per year, with December and January being the worst months. That's the reality solar has to work in. Here's what a professional fixture actually delivers seasonally:
- June to August. 7 to 9 hours nightly at full brightness.
- September to October. 6 to 8 hours nightly.
- November to February. 3 to 5 hours nightly. Expect occasional "dead" nights after multi-day snow events that cover the panel.
- March to May. 5 to 7 hours nightly, improving through spring.
The snow-cover problem
A panel buried under 3 inches of snow produces nothing. On critical signage, we sometimes specify fixtures with angled or vertical panel mounts that shed snow naturally. Path lights along plowed drives typically get cleared by the plow, so they recharge fine.
Solar vs Low-Voltage: The Honest Comparison
Low-voltage wired systems win on brightness, consistency, control, and lifespan. Solar wins on installation flexibility and zero electrical consumption. The question is rarely "solar or low-voltage" across an entire property. The answer is usually "both": wired low-voltage for the main landscape lighting, solar for two or three remote locations where running cable is impractical. See our low-voltage vs high-voltage guide for a deeper comparison of wired systems, and our outdoor lighting page for wired design details.
Pricing for Solar LED Lighting in Oakland County
- Single sign-monument solar light (commercial): $400 to $900 installed
- Solar path light (professional grade, brass): $180 to $350 per fixture installed
- Residential solar accent package (6 fixtures): $1,800 to $3,200 installed
- Commercial solar system for remote signage: $2,500 to $8,000 depending on panel and battery sizing
Maintenance and Replacement
The LiFePO4 battery is the limiting component. Budget on replacing batteries around year 6 to 8. We stock batteries for all the professional lines we install (SolarLightsEtc, Solatron, Gama Sonic commercial). Panel and LED typically last the life of the housing. Spring maintenance involves wiping panels clean, checking housing seals, and re-aiming any fixtures that shifted over winter.
