We have had periodic problems with the hardware and have called Wiki Wiki to fix. Customer service (Jandy) and techs have always been courteous and prompt. I recommend Wiki Wiki Solar and Electric as a reputable company. My caveat is that you should check your PV performance routinely either through the HECO online dashboard or through the equipment manufacturer's app. Parts breakdown and if you don't stay on top of the performance you will be wasting the electrical savings. Use a competent and responsive solar installation/repair company. I find Wiki Wiki to be just that kind of company.

Save your time, guys. Read this…read more I've reached out to 20 solar contractors to cover my whole roof with solar panels, connect 4 Tesla Power Wall 3 batteries and go off grid. I had that well-known feeling, like you're dealing with used car dealerships. The salesmen lied right in my face countless times just to get the contract. I was quite disappointed with a few contractors with flashy websites. Damon's offer was the best in terms of price/quality. He didn't send any salesmen to my house, because he shows up himself. I wish I didn't have to waste my time on talking to everybody else. He showed up as promised. There were no hidden extra fees. No broken deadlines. It all went smooth. Our solar system perfectly resisted the outage which lasted for 6 hours in January 2025.

Camilo is our first point of contact with anything solar so when we found a huge bulge in our…read moreceiling due to a leaking hot water solar pipe we knew who to call for help. Camilo kindly did a quick face to face video with hubby so he could help him turn off the water to stop the leak instantly, and then Camilo came a few days later to do the repair. As usual he worked professionally, quickly, and was thorough and we had our solar hot water running leak free within an hour or two. Laulima is also very competitively priced compared to other companies, and Camilo is always on time and friendly, and totally trustworthy. I'm not the only one who has Camilo as our solar contact, read his reviews here and see how many other satisfied customers use Laulima too.

WOW, They were the best Solar Company and explained everything to me. I asked why are they not…read moreselling me Tesla Batteries and wanted to install Franklin Batteries on my house. Now I know why. All I had to do was Google Tesla VS Franklins. Tesla uses car batteries for their home batteries which means their chemistry is NMC. Franklin is a safer chemistry made of LiFePO4. No solar company wanted to touch my tile roof because they brake easily. They took 3 samples of my tiles and made special clips. They removed my water heater solar panel because I put in tankless water heater. All the tile under my solar panel were broken and they fix my roof plus patch other places while there were on my roof. They even clean my gutters which was so unbelievable. They now make their own home Battery call the HIVE. It wasn't available last year since they only did the HIVE battery for commercial use. They are inventors, scientists and engineers, They make machine from a machine. I've know Dan the owner over 20 years when he was on Eha Street in 1000 sf warehouse working for the military on our Haleakala telescope. They work for Nasa growing plants on our space station. During Covid the hospitals couldn't get ventilators so HNU made them. They won the 2011 Maui County Energy Award. There is not another company that take so much pride in the work. If I call them for anything they come. During our Lahaina Wildfire I live in Napili. They even installed a Starlink to my house. I'm proud to say that they are more than a PV Solar company and they are here to stay and my friends. They are located in Kahului and are in 20,000 sf of office/warehouse. My bill was at times over $900 a month and my 3 Franklin battery are set at 20% so no matter if we had an outage they will never drain my battery to restart as long as the sun is out. My bill is around $60 a month now. This was the best investment and so happy I have 43 PV panels and 3 Franklin batteries. I just wished the Hive home battery was around last year. It's stackable and takes up less space and would of been less labor. GO HNU ENERGY

Back in September 2023 reported issue of Tesla Powerwall+ not working correctly…read more The issue is during daylight hours the battery will switch over to standby mode where we do not have use of energy until dark (about 6pm) For instance if we charge car or use dryer during the day solar energy may only provide 50% of energy needed it should pull remaining energy needed from battery but instead it pulls from the grid. This is when the battery is at 100%. Two separate occasions Sep-Dec 2023 Haleakala Solar came out and attempted repairs. Throughout this time I reported approximately 20 to 30 emails with screenshots documenting issue and that issue was still occurring I contacted battery bonus program to see if this could be an issue. And also to cancel the installation of program since Haleakala Solar never provided HECO proper documentation for HECO to validate data.. I had to fill out a form send it in to get this program canceled since Haleakala Solar wouldn't. In December President Jim Whitcomb during phone call even admitted that Haleakala failed on their part getting the battery bonus program working and lack of service he assured me they would get it working. I asked Haleakala Solar several times could this issue be related to Battery program that was never successfully hooked up and I was assuring no. Contacted Tesla after several long 15 to 20 minute phone calls with them plus numerous emails documenting issue back and forth. As of early December it's in Tesla Tier two tech support and their recommendation December 24, 2023 was "Further your advanced settings need to be changed to export everything as opposed to solar only. Please go to settings, powerwall scroll down to advanced settings, permission to export to change the setting. Which I emailed to Haleakala Solar and they never came out to try. In late December conference call with Jim Whitcomb president and Mokihana Techical Lead at Haleakala Solar sent him screenshots of issue. Mokihana guessed it was low internet signal and they were to install a booster. I sent him Tesla's recommendation. They never came out to try either fix. From December to Feb to sent emails to Haleakala Solar documenting issue still occurring. And my new strategy was to find another solar company and bill Haleakala for its repair. Several companies didn't want to get involved in another's mess. 2/14/24 Filed BBB complaint which they said responded "We are working on finding a solution to what is happening with the battery at Mr. Taylors house. I will contact out head electrician and the owner and see when the soonest we can get out there will be. " 2/23/24 Filed compliant with State of Hawaii DEPARTMENT OF COMMERCE AND CONSUMER AFFAIRS 3/1/24 Sent Haleakala Solar a registered letter including a demand to repair within 14 days or face legal action for breach of warranty. Needless to say I'm sure when this is resolved I will never get any help from Haleakala Solar on any warranty service. Its worth it though letting everyone know our experience with Haleakala Solar's unbelievably poor service.
