Sunnova Energy Reviews

Reviewers most often describe problems with sales clarity and expectations. The main pattern is that proposal promises, savings claims, and follow-through on what was sold did not match what customers say they experienced.Solar.com's composite of published customer feedback, not a customer quote

Promises not reflected later. Reviewers say the sales message often did not line up with the final project experience, with some describing missed promises and confusion about what was included. Representative review excerpt: "Our project took nearly two years, cost us thousands of dollars more than quoted and they did not make good on any promises from the sales reps that they hired."

Savings claims disputed. Some reviewers report being told the system would eliminate their bill or create savings, but later felt those expectations were not met. Representative review excerpt: "They promised me that my SCE bill would be eliminated and that I would only be paying them, claiming I would actually save money."

Sales responsiveness vs. support. A recurring complaint is that responsiveness feels stronger during the sale than after the contract is signed, especially when customers need help with their system. Representative review excerpt: "They are quick to respond when they think a sale is to be completed but if you need help with your system they don’t want to be bothered."

Reviewers largely report dissatisfaction with pricing, billing, and financing details. The complaints center on charges that differed from expectations, refund delays, and confusion tied to payments or incentive timing.Solar.com's composite of published customer feedback, not a customer quote

Unexpected higher costs. Several reviewers say the project ended up costing more than they were quoted, with some reporting charges they did not expect from the original agreement. Representative review excerpt: "Our project took nearly two years, cost us thousands of dollars more than quoted and they did not make good on any promises from the sales reps that they hired."

Billing and principal issues. Some customers describe problems getting billing corrections made, including concerns about how payments were applied and whether the contract matched what was charged. Representative review excerpt: "Finally spoke to someone in their billing department who advised me that a correction cannot be made to past payments applied to the principal."

Refund delays. Reviewers also report waiting for refunds or resolutions after being told items still needed internal approval. Representative review excerpt: "On July 16, I called again and was told it still needed “internal approval.” Almost a month later, no refund, no accountability, and no resolution."

This is one of the weakest areas in the review set. Reviewers frequently describe slow responses, conflicting information, limited ownership of issues, and repeated follow-up calls to get updates or action.Solar.com's composite of published customer feedback, not a customer quote

Hard to get a clear answer. Reviewers say they often could not get a straight answer about project status, activation timing, or next steps, even after repeated contact. Representative review excerpt: "I called them and they couldn't give me an answer when my solar would be activated with Southern California Edison."

Conflicting information. A common theme is being passed between representatives and receiving different answers each time, which left customers feeling they had to keep calling. Representative review excerpt: "Since then, I’ve called so many times, spent hours on the phone, and have been given the runaround by different reps with conflicting info every time."

Support feels uneven. Some reviewers report that the company responded more quickly during the sales process than when customers needed help after the system was in place. Representative review excerpt: "They are quick to respond when they think a sale is to be completed but if you need help with your system they don’t want to be bothered."

Reviewers frequently describe long delays and missed timing commitments. The main issues involve delayed activation, appointments that did not happen, and slow movement on permitting or utility-related steps.Solar.com's composite of published customer feedback, not a customer quote

Activation delays. Some reviewers say they could not get a clear timeline for when their solar would be activated, even after multiple calls. Representative review excerpt: "I called them and they couldn't give me an answer when my solar would be activated with Southern California Edison."

Missed appointments. Customers also report confirmed appointments where no one arrived and no one contacted them to cancel or reschedule. Representative review excerpt: "I received an email confirming the June 19 appointment, but no one came, and no one contacted me to cancel or reschedule."

Applications not submitted promptly. Several reviewers describe waiting months only to learn that paperwork or applications had not yet been submitted. Representative review excerpt: "However, after waiting for three months, I called today and was told that they had not even submitted my application to SDGE yet."

Reviewers report mixed but mostly negative experiences with installation quality and site care. The complaints focus on damage, cleanup or repair issues, and situations where customers felt the company did not take responsibility quickly.Solar.com's composite of published customer feedback, not a customer quote

Property damage concerns. Some reviewers say installation work left damage to the home, including attic or roof-related issues that later needed attention. Representative review excerpt: "One of the most disgusting things they did was when they put holes in my attic vent and just plugged them with plastic, which led to mold growing throughout my..."

Repair responsibility disputes. A recurring complaint is that customers felt the company did not address reported damage promptly or reasonably after the work was done. Representative review excerpt: "Sunnova caused extensive damage to our house and has spent the better part 9 months trying to find a way not to address this issue reasonably."

Scheduling and site mistakes. Reviewers also mention missed scheduling details and follow-up problems tied to the installation visit itself. Representative review excerpt: "I asked for the $100 they would have charged me had I done this to them but they are of course not taking responsibility for confirming the wrong day."

Post-install feedback is mostly negative, with reviewers describing system issues, service delays, and difficulty getting help after turn-on. Complaints often center on broken equipment, limited repair access, and uncertainty about whether the system is working as expected.Solar.com's composite of published customer feedback, not a customer quote

Repair support is difficult to reach. Reviewers say they struggled to get service or repairs scheduled after installation, sometimes after repeated attempts. Representative review excerpt: "I have not had service since Oct 2024 and I can't get ahold of them to for repairs."

System or battery issues. Some customers report problems with batteries or other system components not working properly for extended periods. Representative review excerpt: "After moving into a brand new home that comes with solar panels and a battery, they have been unable to get a working battery for me and it's been 5..."

Post-install help feels limited. Several reviewers describe difficulty getting effective help once the system was already installed, especially when something on the system needed attention. Representative review excerpt: "I called customer service and "Anna" told me: "I know your system is broken, but we cannot give 3rd party access to your system to fix it, and we can't..."
