The Verdict
WikiWiki Solar and Electric is the installer you call when your system goes down and everyone else ghosts you. We found a half-dozen reviews from customers whose original contractors vanished, leaving them stuck with broken equipment. WikiWiki showed up, often within hours, and fixed systems they didn't install. One off-grid farm facing three dying freezers watched their first installer ignore frantic calls while WikiWiki arrived the same day and restored power in an hour. That repair-on-demand responsiveness carries through new installs. Crews routinely finish panel and Powerwall jobs in a single day, and 30 reviewers singled out post-installation support with zero complaints about follow-up. The sales team educates rather than pushes, walking customers through NEM-plus upgrades and competitive bids without pressure. One repeat customer installed two separate systems years apart, each time praising how easy WikiWiki made the process. The minor trade-off: a handful of reviews mention billing confusion or delayed permit paperwork, but none derailed a project.
If you want an installer who'll bail you out when hardware fails at 2 a.m., WikiWiki is worth the call. They've earned a reputation for showing up when competitors don't answer the phone.
3 Stories That Stood Out
Meganj Wells runs an off‑grid organic farm where nine people live and work, and when their Tesla system began failing she faced the real threat of losing the contents of three refrigerators and three freezers. For two days they endured noisy, fuming generators while their original installer failed to respond and calls to other companies went unanswered — answers only trickled in by email days later, which was useless for a property that isn’t tied to the grid. WikiWiki showed up within hours of her call, hooked up with Tesla support on the phone, and had the system running again in about an hour, preserving the food and ending the generator noise. She walked away most impressed by the fast, hands‑on coordination with Tesla — the kind of immediate response that matters when you live off‑grid.
Brian shopped for a solar system and walked away impressed by how smoothly everything went. He learned the salesman’s clear explanations about options and trade-offs, and got a very competitive price. The installation crew arrived professional, tackled the small challenges that came up, and completed the work on schedule. The manager stayed on top of the details, handling all the follow-up with the inspector and paperwork so the permit was secured — the kind of follow-through that made the whole process feel effortless.
Mike already had a NEM system on his Wailuku residence installed by WikiWiki, and when he decided to expand he added a NEM Plus system with the same team. He chose them again because they had handled the original work, and he found the whole process professional and straightforward — the crew managed the new add-on without fuss. After two installations handled by the same company, he now relies on WikiWiki as his go-to for both electrical and solar needs, having walked away with a seamless upgrade and a trusted local contractor for future projects.

What You Can Expect
Charlene had Wiki Wiki Solar put panels on her home in 2020. While the installation crew and ongoing service left a positive impression, she discovered the system hasn’t noticeably reduced her electric bills. Even more frustrating, the house loses hot water whenever it rains — the opposite of what she expected when signing up. She wants the company to correct the problem, and if they can’t, she will look for a new solar provider. The detail that sticks with her: the panels haven’t translated into real savings, and rainy days still mean no hot water.
Jed Gerlach started with no knowledge of solar and handed the project to Shane, who designed a system for his home that has performed beautifully for two years. The installation crew arrived professional and clearly knew their work, and Jed checked other options before signing on—he couldn’t find a better combination of equipment or price elsewhere. What stood out most was how a designer and crew turned a confusing purchase into a reliable, cost‑competitive system that’s still delivering after two years.
Jed G. started out unsure what his home needed to go solar, and Shane stepped in to design a tailored package at a competitive price. He ended up with a system installed by a crew that proved professional, friendly and clearly knowledgeable throughout the process. The panels have powered his home flawlessly for almost two years, and he plans to work with Shane again when he needs anything else.
When Marv needed a new set of solar panels and a battery, he went with Wikiwiki Solar and Electric. He found the crew worked quickly and took care of everything—walking the required paperwork and technical details through Hawaiian Electric so he didn’t have to get bogged down. The installation delivered the same dependable performance he experienced with his first Wikiwiki system five years earlier, and the smooth handling of the utility interactions is the detail he keeps remembering.
Steve M. bought a house in 2022 that already had a PV and battery system installed by Wiki Wiki for the previous owner and discovered the equipment remained under the original warranty. Over time he encountered a few intermittent hardware problems and called Wiki Wiki for service; customer-service rep Jandy and the field techs consistently showed up courteous and prompt, which became the standout of his experience. He learned the hard way that panels and battery components can break down, so he kept a close eye on system output through the HECO online dashboard and the equipment manufacturer's app to avoid bleeding away the expected savings. Ultimately he relied on Wiki Wiki’s responsiveness to keep the system running — his practical takeaway: when buying or owning a preinstalled system, monitor performance regularly and have a competent, responsive installer on call.
Richard B. chose WikiWiki Solar a year ago for a 20-panel system with battery storage for his Kihei home. He agreed on a timetable and the full crew arrived on schedule; the team worked neatly, courteously, and finished the install quickly. The system has performed as expected with no service visits needed. When he later decided to add capacity, WikiWiki already had the parts in stock and completed the upgrade within a week. He recommended them to friends and neighbors and heard nothing but praise — the fact that they kept equipment on hand and handled the expansion so fast is the detail that stuck with him.
Marv C. had Wikiwiki Solar and Electric put in his home system five years ago and recently had them back to add two more panels and install a new Tesla battery. He found the upgrade just as smooth and professional as the original job — the team handled the equipment and integration cleanly and without fuss. Because the service stayed consistent over time, he has recommended Wikiwiki to friends and family, pointing to their reliability and ability to perform both initial installs and later battery upgrades.
Mike already had a NEM system on his Wailuku residence installed by WikiWiki, and when he decided to expand he added a NEM Plus system with the same team. He chose them again because they had handled the original work, and he found the whole process professional and straightforward — the crew managed the new add-on without fuss. After two installations handled by the same company, he now relies on WikiWiki as his go-to for both electrical and solar needs, having walked away with a seamless upgrade and a trusted local contractor for future projects.
Jamie had solar put on a Wailuku home and then brought the same crew back to outfit a second house in Waihee — the repeat hire is the clearest sign this went well. They found the team easy to work with and the price fair, and ended up with what feels like free electricity. The everyday payoff is simple and tangible: they run the air conditioning without worrying about the bill. Mahalo captures the gratitude that sent them back for a second install.
