How to read your solar monitoring app

What the three major solar monitoring apps show you

Enphase’s app, the mySolarEdge app and the Tesla app all let you view production by hour, day and month, but each platform organizes the data differently. Enphase reports each panel’s output almost live, so you’re seeing individual components rather than a system average. This matters if you have microinverters because you can isolate which specific panel is underperforming.

SolarEdge shows a map of your roof with each panel, string and inverter in place. Brighter blue panels are producing more and darker blue panels less. The Tesla app centers on an animated energy flow diagram that shows, at any moment, how much power the panels are making, what the house is using, whether the Powerwall is charging or discharging, and what’s moving to or from the grid.

All three platforms are free to homeowners at the basic monitoring level. Enphase doesn’t charge a monthly fee for its core monitoring. The apps differ most in how they present module-level versus string-level data and whether they integrate battery or EV charging controls. If you’re deciding between systems before installation, check out vetted installers near you who can walk through which monitoring platform best fits how you’ll actually use the data.

Understanding the daily production curve (and what shape is normal)

On a clear day, production should trace a smooth hill: it starts low after sunrise, peaks around solar noon, and tapers off through the afternoon. This bell curve is what you should see on a clear day with no obstructions. If your curve looks symmetrical and smooth, your system is performing as designed.

In practice the curve gets bent by clouds, morning haze, late-day shade from trees or buildings, and the shift in sun angle and day length through the year. A single cloud passing over your roof will show up as a sharp dip in your production graph. If that dip disappears within minutes, it’s weather, not a problem with your system.

Shade shows up as a dent in the curve. If that dent lands at the same time on clear day after clear day, something fixed, like a tree or a neighbor’s roof, is blocking the sun. Compare your curve across multiple clear days at the same time of year. A dip that shows up at 3 PM every sunny afternoon in June means something is blocking your panels at that specific sun angle, and it’s probably fixable. Learn more about how shading affects output in our guide on how solar performs in different conditions.

How to spot shading signatures in your production data

Shading doesn’t always look like a smooth dip in your curve. Because of how cells are wired together, shade on a small slice of one panel can cut that panel’s output by half or more. Once you recognize the stair-step pattern, you can trim trees or address the cause before losses add up. The key is looking for patterns that repeat at the same time every day during clear weather.

Morning shading typically shows up as a delayed start to your production curve—your system doesn’t ramp up until later than it should for your geographic location. Afternoon shading appears as an early drop-off, where production falls faster than the gradual bell curve decline you’d expect. If you see a consistent notch or step in the middle of the day, that’s usually a chimney, vent pipe, or tree branch casting a shadow as the sun moves across the sky.

SolarEdge and Enphase systems make this easier to diagnose because you can view panel-level data. Seeing the whole array laid out makes it easy to spot exactly which part isn’t pulling its weight. If one panel consistently shows 30 percent lower output than its neighbors on the same roof plane, and that underperformance shifts throughout the day, it’s being shaded. If it’s low all day long, the panel itself may have failed or a connection may be loose—time to call your installer.

What self-consumption ratio means and why it matters

Self-consumption is the share of your solar production that your home uses directly instead of sending to the grid. For example, if your panels make 30 kWh in a day and the house uses 18 kWh of it as it’s produced, your self-consumption is 60%. The other 12 kWh, or 40%, goes out to the grid. This number tells you how much of your solar production you’re using directly versus sending back to the utility.

Homes without a battery usually land somewhere around 25 to 30%, and households with someone home during the day can push that toward 35 to 40%. Without storage or deliberate load shifting, it’s hard to get much above that range. If you have a battery, time-of-use rates, or an electric vehicle, your self-consumption ratio becomes much more important because you can strategically use or store your solar production rather than exporting it at low compensation rates.

Keep in mind that 100% self-consumption doesn’t mean solar covers all your electricity. It only means none of your solar is exported. A system sized for 80% of your usage can hit 100% self-consumption and you’ll still buy power from the grid. Don’t confuse this with self-sufficiency, which measures what percentage of your total consumption comes from solar. Both numbers matter, but they measure different things.

Comparing month-over-month and year-over-year production

Your solar system will produce dramatically different amounts of energy across seasons, and that’s completely normal. In winter the sun sits much lower in the sky even at midday, so less direct light reaches your panels and both peak output and daily totals fall. In most U.S. locations, you’ll produce 40 to 60 percent less in December than you do in June.

The right comparison is not January 2026 versus July 2026. Compare January 2026 to January 2025. If this January produced 15 percent less than last January and nothing has changed with your system, check for new shading sources—did a neighbor’s tree grow? Did someone install a structure nearby? Small environmental changes compound over time.

Most monitoring apps allow you to view historical data by month and year. The Enphase app can compare your production against historical weather. If your production dropped but your area had unusually cloudy weather that month, your system is fine. If production dropped on sunny days, you have a real issue. Track your monthly kWh totals in a simple spreadsheet and you’ll quickly build a baseline for what normal looks like for your system in your location. If you’re consistently falling short of projections your installer provided, it may be time to contact them—or if they’re no longer in business, see our guide on what to do when your installer has closed.

Reading energy flow diagrams (solar, home, grid, battery)

Energy flow diagrams show you in real time where your electricity is coming from and where it’s going. The Tesla app draws your house with live power flows from the panels, battery, grid and home. SolarEdge and Enphase offer similar visualizations. These animated diagrams are helpful for understanding what’s happening at any given moment, but they’re less useful than the historical graphs for spotting long-term problems.

A typical day looks like this: around midday, solar runs the house and charges the Powerwall. In the evening, the Powerwall takes over. Once it’s empty, the house pulls from the grid. Watch your flow diagram during midday and you should see solar powering your house with excess going to your battery or the grid. At night, you should see either battery discharge or grid import, depending on whether you have storage.

Power flowing in from the grid just means your home needs more than the panels are making right now. That’s expected at night, on cloudy days, and whenever usage spikes. Don’t panic if you see grid import during the day while your system is producing. If you’re running your air conditioner, dryer, and oven simultaneously and your system is only producing 4 kW, the extra load has to come from somewhere.

Setting up app alerts so you don’t have to check daily

Here’s the truth about solar monitoring apps: most people check them obsessively for two weeks after install and then forget they exist. That’s fine—your system is designed to run without daily oversight. But you should configure automatic alerts so the app notifies you when something actually goes wrong. Tesla’s app sends push notifications when something changes or looks off, and Enphase and SolarEdge offer similar notification features.

Enphase can email you automatically when an event affects production. Those alerts flag equipment or wiring problems, and when the issue is on the roof they tell you which panel is affected. Set your alerts to notify you for system offline events, consistent underproduction compared to expected output, and individual component failures. Don’t set alerts for minor production dips—clouds are not emergencies.

With alerts configured, you can check your app once a month just to confirm everything looks normal, and trust that you’ll get notified if something breaks. This is especially important if you’re on a time-of-use rate plan or have a battery system, where your monitoring app can also alert you to changes in battery behavior or unexpected grid import during periods when your battery should be discharging. For a deeper look at how batteries integrate with solar, see our comparison of Tesla Powerwall versus SolarEdge battery systems.

When monitoring becomes more important: batteries, EVs, and time-of-use rates

For most solar-only homeowners, monitoring is a set-it-and-forget-it proposition. You confirm the system is producing, you check it occasionally to make sure nothing has broken, and you move on with your life. But if you add a home battery, an electric vehicle, or move to a time-of-use rate structure, your monitoring app becomes significantly more useful because now you’re making active decisions about when and how to use your solar production.

SolarEdge’s consumption view shows when your home uses energy, so you can move flexible loads into sunny hours or cheaper rate periods. Tesla owners can set the app to charge their car using only surplus solar. These features let you maximize the value of every kWh your system produces by using or storing it strategically rather than exporting it to the grid for minimal credit.

If you have a battery, you’ll use your app to monitor state of charge, confirm your battery is dispatching correctly during peak rate periods, and track how much of your evening usage is coming from stored solar versus the grid. Your Powerwall’s operating mode decides how it charges and discharges, and plenty of owners have never checked which mode they’re on. Check your battery settings and make sure they align with your utility rate structure and your actual usage patterns. Your monitoring app is the only way to confirm your system is doing what you intended when you set it up.
