  • How often should I get a maintenance on my solar hot water system?
    It is recommended you get a maintenance on your solar hot water system every 3-5 years, as your system's anode rod disintegrates in that timeframe. Eligibility for the Hawai'i Energy rebate is every 5 years on a solar hot water maintenance service.
  • Why is +(web) important on my PV system's gateway (envoy)?
    Communication between the envoy and microinverters is important in order to see daily production from each microinverter, if microinverters are properly producing, and/or to process a claim with Enphase Energy. Enphase Energy Microinverters hold a 20-25 year manufacturer's warranty (depending on the model).
  • How can I tell if I have +(web)?
    You can login to your Enlighten manager account,, where your envoy will show a green check mark and display +(web). You can give us a call at 808-261-9740 and we can check on Enlighten for you. Newer model gateways (envoys) have green and/or lights to display a +(web) or -(web). Older model gateways (envoys) have a small green LED screen that will display +(web) or -(web) in text.
  • I cannot get a +(web) connection and need additional assistance.
    Give us a call, 808-261-9740, and/or send us an e-mail,, and we can schedule a technician to come out to your home to troubleshoot and re-establish a +(web) connection for you. *Please note, there are no warranties for -(web) circumstances, labor charges will apply. At home troubleshooting: If you have an "Ethernet Connection," you will have 2 wireless bridges. One plugged into your system's envoy and a second, matching bridge, plugged into your home's internet router. You can unplug both bridges, wait 1 minute, and plug back in. This will re-send the internet signal back and forth from each other, hopefully re-establishing a +(web) connection.
  • Does my photovoltaic system work in a blackout?
    If your solar panel system is connected to the grid, it will shut off in the event of a blackout. This is to prevent emergency responders and electricity utility repair-people from being injured by your panels sending power back to the grid.

    State Tax Credit: 35% of system cost Federal Tax Credit: 26% of system cost *As of 2022. Percentages are subject to change each year.
