Sunergy Solar features an A+ rating and accreditation with the Better Business Bureau (BBB). The company only features two highly positive reviews on its BBB page. This is most likely because it’s a very localized company. We also analyzed the company’s 100 most recent Google reviews. Sunergy customers mention the company’s highly personable and professional customer service team and the high quality of its installations. The few negative reviews presented either did not provide enough information or mentioned possible leaks years after installation.

Here are some of the reviews we analyzed during our research.

Positive Reviews

“Everything went perfectly! The installers knew exactly what they were doing, were friendly, and [were] happy to answer any questions. They were also respectful of our property and cared about cleaning up afterward. Over the years, we have had a few questions[,] and Sunergy responded quickly with the answers. We recently had them out once again to install a different mixing valve and had the same experience: friendly, informative and excellent work. …  I would highly recommend Sunergy Systems to install your solar panels or any other connected work. 6 years later, we are both still very happy.”  — Marian A., February 16, 2021, on BBB

“Great local employee-owned company with exceptional customer service and craftmanship.” — Bob R., April 26, 2021, on BBB

Negative Reviews

“I hired Sunergy 6 years ago. Originally, they did a good job, but here are the problems I’ve had since the install… There was water intrusion into the inverter!! They “fixed” it by drilling a weep hole. I don’t know about you, but I’m *still* concerned about high voltage and water in the inverter! … Leaks in the roof. They do not have proper on-call processes in place when their office is closed. I notified them about the leak[,] and they were only able to get someone to the house to take a look 2 weeks later.” — Paul Kim, January 2023, on Google Reviews

“Interesting company: they did call back after I left a message, but only to tell me that a solar install was not going to work because[,]in their words[,] ‘your house has a PVC roof’ – which is incorrect, the roof is asphalt not PVC, and it is going to be replaced soon anyhow with something solar-panel compatible, but they didn’t think to ask about this, and a solar install is ‘not going to be cost[-]effective…’.” — Benjamin Dunlap, July 2022, on Google Reviews


What Are the Different Sunergy Payment Options?

Sunergy Systems partners with lending agencies in Washington to deliver customers three financing options: solar cash, solar loan, or solar lease. Learn more about these options below.

  • Cash payment: Solar cash allows customers to forgo monthly payments and pay for their system in full. This payment method provides an immediate return on investment, and it increases your home’s property value by roughly $15,000. Additionally, because you fully own the system, you can use any available solar tax incentives.
  • Solar loan: Solar loan customers pay a fixed monthly payment and an interest rate with the option of a 10-, 15-, or 20-year term. You’ll pay more for this option in the long term due to interest rates. You do receive full system ownership, so you receive an increase in property value and access to tax incentives.
  • Solar lease: Signing a solar lease allows customers to pay a set monthly fee for solar energy over 10 years. This option is less cost-effective than the other two because you don’t receive system ownership, so you are disqualified from any incentives. Sunergy discourages the solar lease option because of its termination fees, use of substandard solar equipment, and undisclosed terms and conditions.

What Are the Sunergy Warranty Options?

In addition to the warranties provided by solar module manufacturers, Sunergy Systems offers a SolarClad warranty that contains four system protections.

  • 10-year SolarClad workmanship warranty: The company troubleshoots all system problems that arise due to its workmanship.
  • 10-year equipment replacement labor warranty: If your system fails, this warranty covers the cost of installation and equipment.
  • 10-year 110% performance guarantee: This warranty guarantees a set amount of system production over 10 years. If your system doesn’t meet standards, Sunergy reimburses 110% of the lost electric bill savings and incentive revenue.
  • 10-year performance verification service: This service promises 24/7 performance monitoring and quarterly system verification.

Is Solar Worth It?

We find solar panels are worth it for most homeowners. Solar energy systems give you unlimited access to clean energy, so you rely less on expensive fossil fuels and reduce your monthly energy bills. Solar energy also increases your home’s value by roughly $15,000.

Though solar is expensive, the total installation cost has reduced significantly over the past few years. If you can pay for the system in full or take out a solar loan, you will especially receive a cost-effective outcome for going solar.

Solar Incentives and Rebates

Both federal and state governments are increasing their solar tax incentive programs. Net-metering allows you to send excess energy to the power grid in exchange for credits on your monthly energy bills, saving you money. Depending on your energy consumption habits, you can even profit from a net-metering program.

The federal solar investment tax credit (ITC) is another incentive we recommend for all homeowners. This provides a deduction on your federal taxes equal to 30% of your solar panel installation costs.


Our Conclusion

Sunergy is an experienced local solar installer that provides customers with a structured installation process backed by its SolarClad warranty. Although the company only services Washington state, its use of trusted solar equipment allows the company to compete with nationwide providers. If you want a company that is backed by a larger network or can provide more services in your area, you might want to consider a larger solar company like SunPower.

Frequently Asked Questions About Sunergy

How much roof space will my system need?

Sunergy recommends 80 square feet of roof space for every 1,000 watts of solar modules. The average size of a system ranges between 5,000W and 8,000W, so the required roof space is between 400 square feet and 700 square feet.

Can I sell power back to my utility company?

Yes. With net metering, any excess energy your system produces will go to the electrical grid and result in your utility company awarding you credits towards your total utility bill.

Is there any required system maintenance?

It’s recommended that you clean your solar panels annually with soap and water.
