Rooftop Solar Panel Selection - Monocrystalline vs Flexible for Florida RVs
Florida's combination of intense direct sun and high ambient temperatures creates a specific tradeoff in solar panel selection. Rigid monocrystalline panels like the Renogy RNG-200D and the Go Power GP-RV-200D produce rated wattage in Standard Test Conditions (25C cell temperature) but derate approximately 0.4% per degree Celsius above that threshold. On a black rubber EPDM roof in August in central Florida, panel cell temperatures routinely reach 65C - a 16% derating from nameplate wattage. Flexible panels have worse temperature coefficients than the best rigids and also trap heat against the roof membrane because they are adhesive-mounted flush. We recommend rigid panels on Z-bracket mounts with a 1.5-inch air gap beneath the panel for all Florida installs. The air gap reduces cell temperature by 12 - 18 degrees compared to flush adhesive mounts, recovering 5 - 7% of derating losses.
MPPT vs PWM Charge Controllers - Why MPPT is Mandatory for Florida Arrays
A PWM charge controller clips the solar panel's voltage down to battery voltage and wastes the difference as heat. On a 200W panel producing 18V open-circuit connected to a 12V battery bank, a PWM controller harvests only 12/18 = 67% of available power. An MPPT controller like the Victron SmartSolar MPPT 100/30 continuously adjusts its operating point to extract the panel's maximum power point - typically 15 - 17V for a 12V nominal panel - and then steps the voltage down efficiently to charge the battery at 14.4V. In Florida, where full-sun periods are common, MPPT delivers 20 - 30% more charge energy than PWM from the same panel array.
Roof Penetration and Sealant - How We Keep Florida Rains Out
Every solar cable penetration is a potential water intrusion point, and Florida's daily afternoon thunderstorms and hurricane-season deluges make roof sealant selection critical. We use two sealant products on every install. For Z-bracket mount feet and cable gland bases, we apply Dicor 501LSW self-leveling lap sealant - it remains flexible at temperatures from -40F to 200F and bonds permanently to EPDM, TPO, and fiberglass roofs without requiring a primer. For vertical surfaces and the cable gland sidewall, we apply Dicor 551LSW non-sag formulation. After sealant cure (24 hours minimum), we inspect every penetration point with a spray bottle of water and a flashlight inside the coach to confirm zero leakage before sign-off. A 5-year workmanship warranty covers every roof penetration we make.

Case Study: The existing two-battery AGM bank (200Ah usable at 50% depth of discharge) provided only 1,000Wh of safe discharge - enough for roughly 45 minutes of 1,800W AC runtime before the inverter's low-voltage cutoff at 11.5V. No solar was present to replenish daytime discharge.
RV: 2018 Heartland Bighorn 3760EL • Location: Caloosahatchee Regional Park, Site 8 • City: LaBelle
Symptom: The owner wanted to extend their dry-camping stays from one night maximum to four or more nights running the Dometic CCC2 air conditioner for 6 hours per night via a 2,000W inverter, without using the Onan 5500 LP generator during quiet hours.
Diagnosis: Technician logged a 24-hour consumption profile using a Victron BMV-712 battery monitor temporarily connected to the AGM bank. Measured average daily draw: 95Ah from the AC/inverter over 4 evening hours, 22Ah from LED lighting and water pump, 8Ah from slide-out and miscellaneous 12V loads - total 125Ah per day. Florida average of 5.5 peak sun hours means a 400W array produces approximately 165Ah/day after a 20% system loss deduction, exceeding daily demand with margin for cloudy days.
- Roof Survey: Walked the Bighorn 3760EL roof with a measuring tape - located two 48x21-inch flat mounting zones free of AC units, vents, and the Fantastic Fan 3350 cutout. Confirmed both zones face south-southwest with no self-shadowing from the Airxcel AC shroud at sun angles above 20 degrees.
- Cable Routing Plan: Identified a 3/4-inch factory conduit stub through the front storage bay ceiling into the battery bay - sufficient for two 10 AWG solar leads without new roof penetrations.
- Panel Mounting: Mounted two Renogy RNG-200D 200W monocrystalline panels in landscape orientation using Renogy Z-bracket mounts and self-leveling Dicor EPDM lap sealant on all four corner feet and the cable entry gland.
- Charge Controller Installation: Installed a Victron SmartSolar MPPT 100/30 in the front battery bay, mounted on a 3mm aluminum heat-sink plate. Wired panels in series to produce 42V open-circuit, within the 100V input limit.
- Battery Monitor Install: Replaced the factory battery gauge with a Victron BMV-712 Smart shunt and monitor - connected via Bluetooth to owner's iPhone for real-time SOC, amps in/out, and historical data.
- Charge Profile Setup: Configured SmartSolar MPPT via VictronConnect app - set absorption voltage 14.4V, float 13.6V, tail current 2A for the existing Lifeline GPL-4CT 100Ah AGM batteries. Enabled temperature compensation at -4mV/cell/degreeC.
- System Commissioning: Simulated full sun using 400W of resistive load bypass to confirm charge current reached 28.6A into the AGM bank. Ran the AC load test sequence over 3 hours - battery SOC held at 78% with solar input fully offsetting the inverter draw during daylight.
Outcome: The owner achieved four-night dry-camping stays with the AC running 5 hours per evening and generator use reduced to one 90-minute morning run on day four when three consecutive overcast days reduced solar harvest.
Time on-site: 5 hours 30 minutes • Total cost: $299 service call + $890 panels and hardware + $385 Victron MPPT + $165 BMV-712 + $485 labor • Dealer alternative: An RV dealership in Fort Myers quoted $3,850 for the same 400W system but required the coach to be dropped off for a 2-week installation slot.
“We came here to dry camp but were running the generator by 9pm every night. Now we have AC until midnight and the batteries are back to 90% by noon the next day.”

Signs You Need Solar Panel Installation
- ✓Walk your roof before scheduling - confirm the flat mounting zones are free of AC shrouds, roof vents, and the Fantastic Fan cutout and that at least two 48x21-inch panels can be placed with 6 inches clearance from any obstruction
- ✓Know your existing battery bank capacity and chemistry - AGM banks need a different charge profile than lithium, and a new MPPT controller must be configured to match before commissioning
- ✓Check whether a conduit stub from the roof to your battery bay already exists in the factory build - many Heartland, Forest River, and Keystone coaches pre-run a 3/4-inch conduit for exactly this purpose
- ✓Calculate your daily amp-hour consumption before choosing panel wattage - divide your daily watt-hour load by 5.5 (Florida peak sun hours) then add 25% for system losses to get minimum panel wattage needed
- ✓Confirm your shore power cord and converter can handle the combined load if solar panels are charging simultaneously - a 400W array at 30A charge current through a WFCO WF-8935 55A converter leaves only 25A for AC loads
- ✓Plan for the Z-bracket mounting air gap - adhesive flexible panels save installation time but can add 15 - 20 degrees of cell temperature on Florida roofs, reducing harvest by 6 - 8% compared to Z-mount rigid panels

Solar Panel Installation - Common Questions
Straight answers from our solar panel installation service call log.
How many solar panels do I need to run my rooftop AC off-grid?
A 15,000 BTU Dometic Penguin II draws 1,800W running and surges to 2,700W. To sustain 5 hours of runtime per evening without a generator, you need roughly 400Ah of battery capacity (lithium) and a 600W+ solar array to recover that by noon the next day in Florida summer sun. That combination - three 200W Renogy panels, a Victron MPPT 150/45, and two 200Ah Battle Born LiFePO4 batteries - is our most popular Class A off-grid package.
Can solar panels be installed on a fiberglass roof or only rubber EPDM?
Both. Z-bracket mounts with Dicor 501LSW self-leveling lap sealant bond correctly to fiberglass, EPDM, and TPO roofs. The sealant chemistry is different from standard roof caulk - do not substitute with silicone or polyurethane, which do not bond to EPDM and will release within 6 months in Florida heat.
Will solar panels void my RV manufacturer warranty?
In most cases, no. The Magnuson-Moss Warranty Act prevents a manufacturer from voiding the entire rig warranty because of an aftermarket add-on unless the add-on directly caused the warranty claim. Roof penetrations done correctly with proper sealant and without cutting factory structural members do not void roof or electrical warranties.
How do I know if my solar system is actually producing what it should?
Install a Victron BMV-712 battery monitor or a Victron SmartShunt 500A - both give real-time amps-in from solar, state of charge, and historical data via Bluetooth. A 200W panel should produce 15 - 17 amps in full Florida sun. If you are seeing under 10 amps on a clear day, either the panel is shaded, the MPPT controller is in float mode because batteries are full, or the connection has a fault we need to diagnose.
What happens to my solar system during a hurricane - do I remove the panels?
Yes. Z-bracket mounted panels with 3/8-inch stainless lag bolts handle sustained 80 mph wind loads in testing but should be removed if a Category 2 or higher storm is approaching. We use Quick Fist clamps on the mounting rail bolts so panels can be removed without tools in about 20 minutes per panel.
