It's the Season! Have you strung your lights yet?

Solar Christmas Lights: Should You Make the Switch?

By: Alyson McNutt English

Solar Christmas lights don’t cost anything to operate, but are they better than plug-in LED strings?

In the last few years, energy-efficient LED holiday lights have largely replaced more wattage-thirsty incandescent strings, resulting in significant savings -- LED lights use 50% less energy than their incandescent predecessors, and they last up to 10 times longer as well.

Now there’s a newish kid in the string-light neighborhood: LED solar Christmas lights promise grid-free festive lighting.

Powering Up Solar Christmas Lights

A string of solar Christmas lights uses a small solar panel for power; there are no extension cords that must be plugged into outlets. The panel -- about the size of a hockey puck -- powers rechargeable batteries that illuminate a 25- to 100-bulb string of LED lights.

Panels come with small stakes so you can put them in the ground, where they can take advantage of the sun. A fully-charged string of lights should glow for six to eight hours after the sun goes down.

Solar Lights vs. LED Plug-In Costs

Pricing for solar-powered and plug-in LED holiday lights runs neck and neck. Compare purchase prices:

  • A 100-light string of miniature solar-powered LED lights costs about $10 and up.  
  • A 100-light string of miniature plug-in LED lights costs about $10 and up.

Compare costs to operate:

  • Operating a string of plug-in LED holiday lights for 300 hours -- more than enough time for an entire holiday season -- costs about 24 cents, using an average energy cost of 12 cents per kilowatt hour (kWh).
  • Solar-powered Christmas lights, of course, don’t cost anything to operate. That means you’re saving 24 cents per year in energy costs.

Advantages of Solar Lights

  • No extension cords
  • No need for exterior electrical outlets
  • Withstand cold temperatures and precipitation
  • Zero cost to operate
  • Light output comparable to plug-in lighting
  • Green option

Disadvantages of Solar Christmas Lights

  • May not operate under cloudy skies
  • Unproven longevity (too new on the market for results)
