The Central Florida Solar Panel Maintenance Checklist (By Season)

Most solar guides treat maintenance like an afterthought — rinse the panels once a year and call it done. That advice was written for Arizona or California, not Central Florida. Here, you're dealing with oak pollen that bonds to glass in the humidity, squirrels chewing through conduit, afternoon thunderstorms that leave debris on every roof, and summer heat that pushes rooftop temperatures past 140°F. Your solar system needs a schedule built for where you actually live.

This is that schedule. Bookmark it, print it out, and use it every year. Each season covers what you can handle yourself and when it's worth picking up the phone.

And if you've never had a professional set eyes on your system — or if your installer stopped returning calls — Solarama offers a Free Bill Evaluation that takes your last utility bill and tells you exactly how your system is performing against what it should be. No charge. No obligation. Schedule yours here.

Spring: February – April

The Pollen and Wildlife Window

February through April is the most consequential maintenance window of the Florida solar year. Central Florida's live oaks begin shedding pollen in mid-February and don't stop until late April. That fine yellow-green dust doesn't just sit on your panels — it combines with morning dew and UV exposure to form a film that standard rainfall cannot remove. At peak accumulation, that film can cut your system's output by 15–25%.

Meanwhile, winter is when critters move in. Squirrels, birds, and occasionally iguanas spend the cooler months nesting under panel arrays. Spring is when you find out what they left behind.

DIY Tasks — Spring

• Visual roof inspection (from the ground): Use binoculars. Look for yellow-green pollen buildup, bird droppings, and debris accumulation along panel edges. If you can't see the panels clearly, a drone photo is worth the effort.
• Check your monitoring app: Log into your Enphase Enlighten, SolarEdge mySolarEdge, or SMA Sunny Portal app and compare your daily production numbers to the same days in the previous year. A 15%+ drop without a weather explanation is a red flag.
• Inspect accessible wiring and conduit: If any conduit runs are visible from your attic or along exterior walls, look for gnaw marks. Squirrels will chew through plastic conduit to reach copper wiring. This is both a production issue and a fire hazard.
• Look for nesting materials: Birds and squirrels often push debris under the panels at the lower edge. From the ground, watch for straw, leaves, or nesting material sticking out beneath the array.

Call a Pro — Spring

• Professional panel cleaning (April, after peak pollen drop): Don't clean during pollen season — you'll just be wiping wet pollen across the glass. Wait until late April when the drop has finished, then have a professional clean with deionized water and soft-brush technique. Tap water leaves mineral deposits that compound the problem. Solarama's professional cleaning is priced at $18 per panel .
• Critter inspection and exclusion: If you spotted nesting materials or chewed conduit, a pro needs to get on the roof. Critter damage that goes unaddressed will eventually reach wiring. Exclusion mesh installed around the panel perimeter stops future intrusions before they start.
• Inverter health check: Spring is a good time to have an Enphase, SolarEdge, or SMA inverter inspected before the high-production summer months. A failing inverter in July costs you more in lost production than the same failure in December.

Summer: May – September

Peak Production, Maximum Stress

Florida summers deliver your best solar production numbers — long days, intense UV, and high electricity demand from air conditioning running full-time. A 10kW system in Orange County on Duke Energy's 18.1¢/kWh rate can offset $180–$220 per month in summer. That's also why a system problem in June or July is more expensive than the same problem in December.

Summer also brings the rainy season, which runs from roughly June through September. Daily afternoon storms deposit debris on your roof, and while rain does rinse off light dust, it also leaves behind organic material — leaves, seed pods, bird droppings — that sits in the low spots of your array.

DIY Tasks — Summer

• Post-storm debris check: After any significant weather event, do a ground-level visual on your array. Look for leaves or branches resting on or between panels. Even partial shading from a single branch can reduce output from an entire string on older string-inverter systems.
• Weekly monitoring app review: Summer is when you want to be watching your numbers most closely. On a clear day in July, your system should be producing near its rated capacity. If you see a microinverter offline in Enphase's app, or a power optimizer showing low output in SolarEdge, flag it immediately — a bad microinverter in summer costs real money every day it sits unaddressed.
• Check your utility bill: Compare your June–August bills to last year. If your production looks normal on the app but your bill climbed, it could be a net metering issue with Duke Energy or OUC that needs a call to your utility — or a documentation error in how credits are being applied.
• Inspect for critter activity after nesting season: Juvenile squirrels disperse in late summer and look for new shelter. A second wave of critter intrusions under panels is common in August–September.

Call a Pro — Summer

• Post-major-storm panel inspection: If a named storm or a particularly severe squall line came through your neighborhood, have a professional inspect the array for micro-cracks, loose racking hardware, or compromised flashing. Panels that survive a storm visually can still have internal damage that degrades performance and shortens lifespan.
• Mid-season inverter diagnostic: If your monitoring app shows any consistent underperformance that you can't attribute to weather, schedule a diagnostic visit. SolarEdge and Enphase monitoring both generate error codes — a technician can interpret those and address the root cause before it becomes a replacement.

Fall: October – November

The Deep-Clean and Inspection Window

October and November are the quiet months in Central Florida — the rainy season has ended, pollen season hasn't started, and the weather is finally cooperative. This is your best window for annual maintenance work, and the most important time to get a professional inspection on the books before end of year.

DIY Tasks — Fall

• Monitoring app year-in-review: Pull up your full production history for the year in your Enphase or SolarEdge app and compare it month-by-month to the previous year or to your system's projected production. Note any months where the gap is wider than 10%. Bring that data to your annual professional inspection.
• Visual inspection of mounting hardware: From the ground or a ladder positioned safely away from the roof edge, look for any panels that appear to have shifted, any visible rust on racking components, and any sealant that looks cracked or lifted around roof penetrations.
• Review your utility net metering credits: Fall is when your excess summer production credits should be reflecting on your utility account. Verify with Duke Energy or OUC that your credits are being applied correctly before the lower-production winter months draw them down.

Call a Pro — Fall

• Annual professional inspection: This is the one non-negotiable on the calendar. A thorough inspection covers torque testing on all mounting hardware, electrical connections at the combiner box and inverter, panel-level performance validation, and a review of any warranty items. Florida's UV exposure, heat cycles, and wildlife pressure age solar systems faster than in northern climates — annual inspection is how you catch deterioration before it becomes failure.
• Post-rainy-season deep clean: Even if you cleaned in April, five months of Florida weather leaves a meaningful film on your panels. A professional fall cleaning with deionized water restores full capacity heading into winter.
• Roof and flashing inspection: Ask your solar technician to check the condition of flashing around all roof penetrations. Sealant in Florida's climate typically needs refreshing every five to seven years. A small roof leak at a panel mounting point is far cheaper to address in fall than after water damage has spread.

Winter: December – January

Lower Sun, Lower Output — Know the Difference Between Normal and a Problem

Winter in Central Florida means shorter days and a lower sun angle, which genuinely reduces your system's output — typically 20–30% less than your June peak. That's expected. What's not expected is underperformance beyond that seasonal adjustment. Winter is also critter season, as cooler nights drive squirrels and raccoons to seek warm shelter, and the space under a solar array is exactly that.

DIY Tasks — Winter

• Benchmark your production against seasonal norms: In your Enphase, SolarEdge, or SMA app, compare your December and January daily averages to what the system projected for those months during installation. A 10–15% gap below seasonal projections — not just below summer output — is worth investigating.
• Listen for activity near the array: Squirrels and raccoons are most active at dawn and dusk. If you hear movement on your roof during these hours in winter, take a ground-level look at your panels. Critters under an array are far cheaper to remove before they've nested than after.
• Check conduit entry points in the attic: If your conduit runs through the attic, do a visual inspection in December. Wildlife intrusion that started in fall will often be visible — droppings, nesting material, or evidence of chewing — before electrical damage has occurred.

Call a Pro — Winter

• End-of-year system health check: If you skipped the fall inspection or you've had any production anomalies in the second half of the year, winter is a reasonable time to get a technician on-site. Lower production periods are also when it's easiest to schedule service without feeling like you're losing production during the visit.
• Critter exclusion: If you've identified critter activity, winter exclusion work — installing mesh skirting around the perimeter of the array — is time-sensitive. The longer wildlife is under your panels, the higher the likelihood of wiring damage.

The 5-Minute Weekly Monitoring Habit

Every solar homeowner should spend five minutes per week inside their monitoring app. It doesn't require any technical knowledge — you're just looking for anything that changed.

• Enphase Enlighten: Check that all microinverters are reporting. A grayed-out panel icon means that unit isn't communicating. One offline microinverter affects only that panel; multiple offline units in the same area of the roof often signal a wiring or communication issue.
• SolarEdge mySolarEdge: Review the power optimizer map. Any optimizer showing significantly lower output than its neighbors — same sun exposure, same time of day — is worth flagging.
• SMA Sunny Portal: Compare today's yield curve to recent clear days. A flat line during peak sun hours indicates a communication dropout or inverter fault.

The single best thing you can do as a solar homeowner is catch problems early. A microinverter that failed in April but wasn't noticed until October cost you six months of reduced production on that panel — typically $40–$80 in lost generation on Duke Energy's rates, on top of the repair cost.
