Most solar calls come from one of two places: a homeowner weighing whether to install, or a homeowner whose system is already up there and not producing what it used to. Both need the same kind of conversation. For a new system, it is roof condition, shade, and utility rules. For an existing one, it is monitoring data, inverter status, and who holds the warranty.
Call now
- The inverter shows a fault and the system has stopped producing.
- A storm has damaged panels or left conduit hanging.
- Water is coming into the roof at a mounting point.
Can usually wait
- You are gathering quotes and comparing designs.
- Production dipped slightly and you want to understand why.
- You are planning a battery addition or a roof replacement.
Have this ready
- The system size, age, and inverter brand.
- Screenshots from the monitoring app for the last month.
- Roof age and material, plus any shade changes from new trees or buildings.
What the desk hears most
- 01
Deciding whether the roof is ready
A solar array should outlast the roof beneath it. If the shingles are near the end of their life, reroofing first avoids paying to remove and reinstall panels later.
- 02
Shade that was not there before
A tree that grew, a new building, or a changed roofline can cut production more than the monitoring app suggests. A shade study is worth repeating when the landscape changes.
- 03
An inverter that has stopped
Inverters are the part most likely to fail first. Note the fault code, the brand, and whether the unit is still under warranty before calling.
- 04
Panels that are dirty or damaged
Soiling from pollen, dust, or bird activity can dull output. Cracked glass and damaged frames are a different matter. Do not walk on panels to inspect them.
- 05
Adding a battery or expanding the array
A later addition has to match the existing inverter and the utility agreement. The paperwork can take longer than the install.
Call now or wait?
The honest answer depends on whether the problem is contained and whether the house is safe. Use these two lists as a starting point, then call and describe the specifics.
Call now
- Exposed wiring after a stormKeep people away and call the utility if a line is down. Do not touch conduit or panels that may still be energized.
- An active roof leak at a mountPut a bucket under the drip and call. The leak has to be addressed before the array is touched again.
- Battery heat, smoke, or a chemical smellEvacuate and call 911. A battery fire is not a wait-and-see situation.
- An inverter fault with the system offlineShut down only if the manufacturer's instructions say so, and report the fault code. Production lost now may be recoverable, but a bad restart may not be.
Can usually wait
- Quote comparisonTake the time to compare production estimates, not just the headline number.
- Gradual output declineCheck the monitoring history and panel soiling before assuming hardware failure.
- CleaningMost arrays self-clean with rain. A dry, dusty season is the exception.
- Battery planningStart with an energy audit and the utility's rules before choosing equipment.
Before you dial: the 60-second prep
You do not need a diagnosis. You need enough detail for the desk to route the call and for the pro to arrive with the right questions.
- Find the system contract, warranty, and monitoring login.
- Screenshot the production graph for the last 30 days.
- Note the inverter brand, model, and any fault code.
- Check the age and condition of the roof.
- List any new shade sources near the array.
- Have the utility bill and the interconnection agreement ready.
What happens when you call
You describe the system
The call team asks the size, age, inverter type, and what the monitoring shows.
The desk routes the call
Your city and the type of issue determine which independent local solar professional receives the call.
You confirm the visit
Ask whether the visit is diagnostic, repair, or a quote, and what it costs before anyone comes out.
What changes the job here
Housing age, weather, water, soil, and foundation type all change how a solar energy problem behaves. These are the local factors worth mentioning on the call.
Sun hours and latitude
A system that performs well in one region can underperform in another because of sun angle, haze, and summer cloud cover. Local production estimates should use local weather data, not a national average.
Snow and hail
In snow country, panel tilt and clearance decide whether snow slides off or sits for weeks. Hail risk also shapes the panel and mounting choices.
Coastal salt and wind
Salt air corrodes mounting hardware and connectors faster near the coast. Wind exposure and corrosion-resistant parts matter more there than headline panel efficiency.
Utility rules and older roofs
Interconnection rules, net metering, and permit timelines vary by utility and jurisdiction. Older roofs add a second variable: the array's lifespan should not exceed the roof's.
Questions worth asking the pro
Ask before you authorize work. A good professional will answer plainly, including the parts that are still uncertain.
- Who performs warranty work if the installer is gone?
- What does the monitoring show, and can I keep access?
- Will this work require a utility shutdown or a new agreement?
- How will the work affect my roof warranty?
- What is the plan for removal and reinstall if I reroof?
- What production should I expect in a normal year?
