What Do We Think of Solar Energy World?

 Though Solar Energy World has impressive features, its service area is limited, and it doesn’t provide energy auditing services. The company scores highly on its warranty, which is longer than that of most solar companies. Solar Energy World offers a 30-year manufacturer’s warranty on all of its solar panels and inverters, whereas many providers only offer 25-year warranties. It provides multiple financing options and rates well with the Better Business Bureau (BBB).

3. Solar panel installation: Installation typically takes two to three days, depending on system size. 
4. Solar panel system inspection: The installation company sets up the final inspection with the appropriate municipality and/or utility company, then ensures you’re connected to the grid.

Solar Energy World Reviews

Solar Energy World is accredited by the Better Business Bureau (BBB) and holds an A+* rating with the organization. Customers consistently highlight the company’s professionalism, help with applying for financial incentives, and smooth installation process. Some customers, however, reported financial and timeline discrepancies with the company.

Here’s a sample of Solar Energy World’s BBB customer reviews:

“Super easy process. They take care of everything including HomeOwners approval process. Installers were respectful, friendly, and communicative. I would highly recommend!” — Barry F.

“I’ve had solar installed for approximately 3 years. Overall I have been very satisfied with the installation and performance. However, I recently noticed my inverter was not communicating. Solar Energy World service manager, Natalie W*****, informed me that the issue is that my inverter uses a 3G modem. This modem is now obsolete and I would need a new one installed, to the tune of $599… and it can only be installed by them or my warranty is void.” — Gary S.

“We were very pleased with the professional, but friendly attitude everyone at this company had during our solar install project. From the salesman, to the office personnel, to the installation employees–each of them was polite, helpful, and competent. I highly recommend this company.” — Trina H.

“This company took over 6 months to install my solar. They lied to me the whole time about permitting and timelines, broke multiple electrical components of my brand new circuit breaker, and then charged me to fix it.” — Kelly

*BBB rating is current as of April 2024.
