The Verdict
Sunwave Energy has serious billing problems. We found 20 reviews describing systems that drove electric bills up instead of down, with customers paying both their solar loan and a triple-digit utility bill every month. One homeowner expected 2,700 kWh of production per the contract but got only 1,400 kWh for two consecutive months, then couldn't get anyone to return calls. Another reported the panels and grid both feeding the house simultaneously while the battery sat at 90% charge, a configuration that makes zero sense and suggests faulty wiring or inverter programming. The workmanship scores well (68 positive mentions, only 3 negative), but the value score is underwater: 33 positive vs. 18 negative. Post-sale support gets 98 compliments, yet 16 reviewers describe unanswered requests for system checks or bill reconciliation. If you speak Spanish and want a friendly sales process, Sunwave delivers that experience in spades. But if you need someone to fix an underperforming system after install day, you may spend months leaving voicemails while your utility bill climbs.
If you're comparing solar companies purely on installation speed and bilingual customer service, Sunwave checks those boxes. But if you need a company that will troubleshoot a system producing half the contracted output or reconcile double billing, the pattern of ignored follow-up calls is a red flag you can't overlook.
3 Stories That Stood Out
Fabian had a home solar array installed in October 2023 expecting the usual drop in his electric bills. The crew felt friendly and helpful, but the system’s performance turned out to be inconsistent. He saw the bill fall to the expected level around February 2024, but that improvement lasted only about three months. By May 2024 his monthly bill climbed back above $300 and then increased further. He called the company to have the system checked and followed up again months later; they asked for copies of his electric bills, but two months passed without any further contact and the charges didn’t improve. The monitoring app added to the frustration — it’s basic and only shows the overall system running rather than indicating whether an individual panel is offline. He ended up frustrated by the short-lived savings, the lack of technician follow-through, and the limited app visibility that makes it hard to diagnose a single failing panel.
Victor moved forward with a residential solar install that, under the contract, was supposed to produce about 2,700 kWh per month—roughly 110% of what his ranch-style home needs. Instead he discovered that once the system was turned on he was still being billed both his normal utility charge and the solar bill, and the array only produced about 1,400 kWh in July and again in August. He realized the system appears undersized: the company’s own monitoring showed generation well below household consumption in the first cycle, far short of the contracted output. He reached out to vendor Karla Hernandez, who directed him to Hector Marcano, and then tried repeatedly to schedule a meeting with Hector from the first month on. After two months of dual billing and generation roughly half of what the contract promised, he has heard nothing back and is asking for direct contact with Hector Marcano so the underperforming system can be fixed or brought into compliance with the contract. The clearest takeaway: contracted production of 2,700 kWh/month versus actual ~1,400 kWh and continued utility charges—Victor wants a prompt, concrete resolution starting with that conversation.
Odalgis Rojas met salesman Robinson Algarin, who gave a patient, detailed pitch and ultimately convinced them to install a rooftop solar system meant to cut their electricity costs. After the installation, however, they discovered the opposite: they ended up paying twice as much each month — still making payments tied to the solar equipment and also receiving a utility bill of more than $100. Odalgis notices the house often draws power from both the panels and the grid at the same time even when the system’s battery shows more than 90% charge, which felt illogical to them. They called the company countless times to explain the overlap and request a diagnostic visit, but the company never sent anyone and repeatedly ignored their requests. Frustrated and feeling deceived, Odalgis is left weighing legal options and regrets the installation. The detail that sticks: despite a nearly full battery, the home continued pulling grid power and the utility bills never dropped — a red flag about post‑installation performance and service responsiveness that buyers should confirm before signing.
