According to the company's website, nearly all solar panels come with a 25-year manufacturer's warranty; an easy promise to make with predictable and mature technology that has no moving parts. Inverter warranties vary by manufacturer, ranging from 7 to 25 years.

With Third Sun Solar, switching to renewable energy is simple and straightforward. The first step is a free consultation, during which the company's experts design a customized, optimized solar solution; provide estimates on future savings and financial payback, and discuss Smart Solar Financing options.

The Bad

  • Limited Availability
  • No Lease or PPA

Limited Availability 

Currently, Third Sun Solar only provides solar power services to homeowners in Ohio, Indiana, Michigan, Kentucky, and Pennsylvania. Individuals who live elsewhere will need to find a different company that operates in their area.

No Lease or PPA

Third Sun Solar does not offer residential solar customer the option to lease their system or pay only for the system's energy output via power purchase agreement (PPA). While these options neither grant customers ownership of the system nor access to important tax incentives or solar credits, they can drastically reduce the upfront and long-term costs of financing a solar panel system — at no interest. Customers only interested in lowering their monthly electric bill and are not able or willing to take on the substantial cost of their own solar panel system should look elsewhere.

The Bottom Line

Third Sun Solar is a well-established renewable energy provider based in Ohio. The company offers a number of attractive features, including zero-down financing, lengthy warranties, a straightforward installation process, a referral program, and several years of experience. However, Third Sun Solar's residential clean energy services are currently only available in Ohio, Indiana, Michigan, Kentucky, and Pennsylvania. If you live in one of these states, Third Sun Solar is worth considering. However, if you life outside of this service area, we recommend checking out other solar companies that do operate in your state.

VinnieG Cincinnati, OH

Third Sun provided straight-forward, easy-to-digest cost/benefit analysis and carried top tier solar panels. Installation was a breeze. Sometimes, their communications are not clear. Overall, I would hire them again - they know what they are doing.
