Quick Answer
DIY solar kit warranties typically range from 5 to 10 years and may cover parts and labor, while professional system warranties can last up to 25 years and often include more comprehensive coverage. Professional installers may also offer longer-term maintenance and support contracts.
DIY Kit Warranty Limitations
DIY solar kits often come with limited warranties, usually 5 to 10 years, due to the fact that manufacturers cannot guarantee the workmanship and installation quality when a homeowner or a non-professional installer is involved. This means that if any issues arise from improper installation or maintenance, the warranty may be void.
Professional System Warranties
A professional solar system installation, on the other hand, can come with warranties that last up to 25 years, covering both parts and labor. This comprehensive coverage provides homeowners with peace of mind and financial protection in case any issues arise. For example, Enphase Energy’s system warranty is up to 25 years, while Tesla’s Powerwall warranty is up to 12.5 years.
Maintenance and Support Contracts
Professional solar installers often offer longer-term maintenance and support contracts, which can provide homeowners with ongoing support and technical assistance. These contracts may include regular system checks, software updates, and repair or replacement of faulty components. This can help ensure the solar system operates efficiently and effectively for many years to come.
