What information should I look for in the app to spot problems early?
When monitoring your renewable energy system, keep an eye on a few key things in your app to catch problems early. Check your battery's state of charge regularly - if it's not holding charge as well as usual or drops unexpectedly during sunny periods, that could signal an issue.
Watch your solar generation data too. If you notice a drop in electricity production compared to similar weather days, it might mean your panels need cleaning or there's a technical fault. Your energy consumption and export patterns are worth tracking as well - sudden changes can reveal problems with your inverter or system settings.
Make sure you've got alerts switched on for system faults or low battery warnings. These notifications let you sort issues quickly before they become expensive problems. Most importantly, don't just glance at today's numbers - look at trends over weeks and months, as gradual performance drops often show up there first.

Keep Your Solar System Running Smoothly: What to Watch For
If you've got solar panels and battery storage, your monitoring app is like having a health check-up for your renewable energy system. But knowing what to look for can mean the difference between catching a small problem early and facing an expensive repair bill later.
Battery Health: Your System's Vital Signs
Your battery's state of charge (SoC) is the most important number to watch. This percentage tells you how much energy is stored and should follow predictable patterns throughout the day. During sunny periods, you should see steady charging, whilst evening usage gradually drains the battery.
If your battery drops from 90% to 30% during bright daylight hours when you're not home, something's wrong. Similarly, if it's not reaching full charge on clear days, the battery cells might be degrading or there could be a charging fault.
Most quality battery systems lose about 2-3% capacity per year, so gradual decline is normal. Sharp drops in performance aren't.
Solar Generation: Spotting Panel Problems
Your app should show daily solar generation in kilowatt-hours. Compare this against similar weather days from previous weeks or months. A sudden 20-30% drop often indicates:
- Dirt or debris on panels (surprisingly common after storms)
- Shading from new growth on nearby trees
- Faulty inverters or damaged panels
- Loose connections affecting performance
UK weather varies enormously, but your system should still produce some electricity even on overcast days. Zero generation during daylight hours always warrants investigation.
Energy Flow: Following the Money
Watch how energy moves through your system. During peak generation, excess power should either charge your battery or export to the grid. If you're importing expensive grid electricity whilst your battery sits half-empty during sunny periods, your system isn't optimised properly.
Many apps show real-time energy flow with arrows or graphs. These visual displays make it easy to spot when something's not right with your energy management.
UK-Specific Considerations
British weather means your solar output varies dramatically between seasons. December generation might be 80% lower than June, which is completely normal. However, compare like-for-like periods rather than expecting consistent performance year-round.
If you're on smart tariffs like Octopus Agile or Flux, your app should help you maximise cheap rate charging. Some systems automatically charge batteries during off-peak periods when electricity costs just 7-15p per kWh instead of 25-30p during peak times.
Red Flags to Watch For
Several warning signs deserve immediate attention:
- Communication errors: Apps showing "offline" or "no data" suggest connectivity problems
- Temperature alerts: Overheating components can cause permanent damage
- Voltage irregularities: These might indicate electrical faults requiring professional attention
- Consistent underperformance: Generation 40% below expected levels needs investigation
Common Monitoring Mistakes
Don't just glance at today's numbers. Weekly and monthly trends reveal problems that daily fluctuations might hide. A gradual decline over several weeks often indicates developing faults.
Many people ignore notification settings, missing important alerts. Set up push notifications for system faults, low battery warnings, and communication errors. You want to know about problems immediately, not discover them weeks later.
Weather comparison matters too. Your panels won't perform identically on cloudy versus sunny days, but they should behave consistently under similar conditions.
Professional Help
Most monitoring apps connect you directly with installers or maintenance teams. Don't hesitate to contact them if you notice persistent problems. Early intervention typically costs £100-300 for service calls, whilst ignoring problems can lead to £1000+ repair bills or voided warranties.
Regular monitoring takes just minutes daily but protects an investment worth £8000-15000 for typical home installations. Your app is your early warning system – use it wisely.
