Since its entry into the solar panel industry in 1975, Panasonic has maintained a strong reputation for reliability and innovation. Originally producing amorphous thin-film solar modules, Panasonic pivoted to heterojunction with intrinsic thin layer (HIT) technology in 1997—a move that has solidified its standing amongst the top players in solar technology. Known for high-efficiency ratings and robust warranty offerings, Panasonic solar panels remain a popular choice for many homeowners in the U.S. in 2025. This review will dissect the merits and potential downsides of choosing Panasonic solar panels for your home.
Panasonic’s solar panel lineup
Panasonic’s EverVolt line, which includes series such as the H Series, HK Series, and PK Series, demonstrates a range of solar module designs incorporating advanced technologies. Particularly notable are the newest models, namely the HK2 and PK2 Series, which boast efficiency ratings exceeding 22%. Despite being tagged “preliminary” on the EverVolt website, they are a highly anticipated addition to the market.
Aside from solar panels, Panasonic offers the EverVolt home battery system, acclaimed as the best stacking solar battery of 2024 by experts. This battery significantly enhances the utility of a solar-plus-storage system, providing energy backup during outages and helping reduce energy costs by storing daytime energy for nighttime use.
Why choose Panasonic solar panels?
1. Advanced Technology: Panasonic solar panels stand out for their use of HIT and half-cut solar cell technology, optimizing performance in real-world conditions by enhancing energy conversion efficiency. HIT cells, which marry monocrystalline cells with thin-film layers, enable the panels to harness more wavelengths of light.
2. Superior Warranty: The warranty offerings from Panasonic surpass the industry average. With a 25-year product and performance warranty, along with labor coverage for installations by authorized dealers, Panasonic offers one of the most comprehensive warranties available. Notably, their performance warranty promises panels will maintain 92% of their original output after 25 years, except for the PK Series at 86%, which is still standard.
3. Reputable Brand: With a history spanning over a century, Panasonic is a stable brand. Their commitment to their products and customers gives reassurance that they will honor warranties and support their products long-term.
Costs and financial considerations
Panasonic panels are priced at approximately $3.10 per watt, reflecting their premium technology and warranty coverage. Although there are cheaper options available, such as those from Qcells or Canadian Solar, the quality, reputation, and assurance of Panasonic panels often justify the higher cost for many homeowners.
Additionally, Panasonic systems qualify for solar incentives, such as the 30% federal solar tax credit, which can significantly reduce installation costs. Homeowners are encouraged to solicit multiple quotes to ensure they receive competitive pricing.
