Poco Solar Energy is not a safe bet.

Semper Solaris

BBB A+13+ YEARS

Semper Solaris leaves too many customers stranded when systems fail. We found over 200 reviews describing the same pattern: months-long delays for basic repairs, project managers who vanish mid-job, and warranties that turn out to be meaningless when you actually need help.

BBB A+17+ YEARS

Soleeva

LICENSEDBBB A+11+ YEARS

Soleeva is not worth the gamble. We found a pattern of serious, recurring inverter failures that the company seems unable or unwilling to fix.

Tesla

Tesla delivers polished installations but stumbles badly on communication and support. We analyzed hundreds of reviews and found a clear split: the crews who show up at your house are excellent, but getting help before or after that visit is a gamble.

SunStar Energy

BBB F13+ YEARS

SunStar Energy went out of business in 2023, leaving some customers with inoperable systems and active loan payments.

Sunternal Solar

BBB A+10+ YEARS

Don't trust this company with your money.

Suncrest Solar

12+ YEARS

Suncrest Solar isn't a company you can trust with your money. This review should be short because the facts are straightforward: the company filed for bankruptcy in 2017 and sold off its customer contracts to other installers.

Auxin Solar

Auxin Solar is not a residential installer. We found dozens of reviews, but nearly all are either vague cheerleading or complaints about the company's manufacturing operations and business practices, not actual home solar installations.

SUNworks

Sunworks poses a clear risk. Over the past decade, customers report a company that overpromises and under-delivers, then vanishes when the system fails.
