The panels are often fine; the electronics around them are what need attention. ### Inverter swaps Replacing a failed or outdated inverter, often with one that is ready for storage. ### Panel replacement Swapping damaged panels and matching them to the rest of the string. ### Adding storage Retrofitting a battery so your existing panels can carry you through an outage. ### Expansion More panels for a bigger household, an EV or a new mini split. ## Courteous, friendly and professional [4.9 stars from 13 Google reviews](https://maps.google.com/?cid=3231036880803628322) > Nirvana came out to do a simple cleaning for the solar panels on my house! They were very courteous, friendly, and professional! I could tell they were experts in the industry from our conversation and asked them to do a routine check on my solar system while they were there. 5 of 5 Matt Moffitt Google ## How do I know my solar system needs maintenance? Watch the bill and the monitoring app. If your utility bill creeps back up with no change in how you live, the app shows faults or stops reporting, or you can see cracked glass, sagging racking or a film of dust from the street, the system needs a visit. Each of these quietly cuts production. 1. ### Lower bills stopped Your utility bill crept back up without a change in how you live. 2. ### An app full of errors The monitoring app shows faults, or stopped reporting at all. 3. ### Visible damage Cracked glass, sagging racking or chewed wiring under the array. 4. ### A dusty season A haboob or a dry spring left a film you can see from the street. Planning to add storage while we are there? Read about [home battery backup](/services/battery-backup/). Adding a battery or a bigger array sometimes needs a [panel upgrade](/services/residential-electrical/) first, and an older array can be repurposed for an [off-grid solar system](/services/off-grid-solar/) on a cabin or shop. Questions ## Maintenance and retrofit questions How often should solar panels be cleaned in Arizona? Dust, pollen and monsoon grime build up faster here than in most of the country. Many owners book a cleaning and a system check once or twice a year, and after a dust storm if production drops noticeably. My production dropped. Is it the panels or the inverter? It can be either, or the wiring between them. A system check compares what the array should produce with what it does, then narrows it down: soiling, a failed panel, a tripped breaker, a loose connection or an inverter fault. Can you work on a system another company installed? Yes. A lot of our maintenance and retrofit work is on systems we did not install, including ones whose original installer is no longer around. Can I add a battery to my existing solar? Usually. Depending on your inverter, a battery can be added directly or with an inverter upgrade. We check the existing equipment first and tell you which path fits. Free consultation, Arizona statewide ## Get your array _checked_ Free consultation anywhere in Arizona.
