Purchasing from Local Solar Installers – Best Place to Buy Used Solar Panels

An excellent option for reliable used panels is buying from a local solar equipment supplier or installer near you. The benefits of purchasing through local solar companies include:

  • Experienced Inspection – They fully test and vet the quality of used inventory. You get fully-functional, defect-free panels.
  • System Matching – Local installers source panels compatible with the types of solar setups in your area.
  • Professional Installation – Most offer full-service installation and electrical integration after purchase.
  • Ongoing Support – An established local company will be there for system maintenance and repairs.
  • Possible Warranties – Some installers offer used panel warranties covering certain defects and functionality issues.
  • Give Back Support – Proceeds from sales often help fund local solar charities and community initiatives.

Potential downsides to consider:

  • Limited Supply – Local used panel inventory is constrained by what installers have removed and replaced.
  • Higher Price – Panels may cost more than online or direct-from-household purchases. But overall value is stronger.
  • Older Models – Local stocks don’t turnover quickly. Panels may be older than available online.

For a streamlined solution from reputable solar experts, local panel suppliers are a top choice if you can find good value and condition.

Buying Directly from Solar Panel Owners – Best Place to Buy Used Solar Panels

Another option is to buy used solar panels directly from local homeowners or businesses that previously installed panels on their properties. Direct owner purchases offer these possible advantages:

  • Lower Prices – Cut out the middleman and wholesale markup that installers/resellers charge.
  • See System Firsthand – Visually inspect panels working in real field conditions before purchasing.
  • Negotiation Opportunity – Homeowners are often flexible on price if it means avoiding panel removal and disposal costs.
  • Support Local Owners – Directly support solar adoption while recycling panels that otherwise may end up in landfills.
  • Personal Recommendation – Previous owners can provide firsthand reviews on panel performance and reliability.

Some potential disadvantages include:

  • Limited Selection – Choices depend entirely on what nearby owners are removing for upgrades or due to relocation.
  • No Professional Inspection – The risks and responsibility of evaluating panel condition falls entirely on you.
  • No Installation/Support – Must find separate solar pros for system integration, maintenance, and troubleshooting.
  • Roof Access Difficulties – Actually accessing the panels installed on a roof to inspect them may be challenging.

With extra diligence taken during inspection, buying direct from previous owners can yield great savings on high-quality panels. But ensure thorough vetting.
