The number of panels depends on your energy consumption. As a general rule, most RVers find that 200-400 watts of solar capacity meets their basic needs for running lights, charging devices, and powering small appliances. For air conditioning or other high-draw appliances, you'll need 600+ watts.

To calculate your specific needs:

1. List all devices you plan to power
2. Note their wattage requirements
3. Estimate hours of use per day
4. Multiply watts × hours to get watt-hours
5. Add 20% buffer for inefficiencies

Monocrystalline panels are more efficient and perform better in low-light conditions but cost more. Polycrystalline panels are less expensive but slightly less efficient and may not perform as well in partial shade or extreme heat.

Flexible panels typically have a shorter lifespan (5-10 years) compared to rigid panels (20-25 years). They're more susceptible to heat damage and micro-cracking over time but offer advantages in weight and installation flexibility.

For maximum durability in flexible panels, look for:

• ETFE coating instead of PET
• Fiberglass backing for added strength
• Marine-grade materials if possible
• Higher IP rating for water resistance

Yes, many RV owners successfully install solar systems themselves, especially with all-in-one kits. However, if you're uncomfortable with electrical work or roof modifications, professional installation is recommended.

A DIY installation typically requires:

• Basic electrical knowledge
• Comfort working on your RV roof
• Proper tools (drill, wire crimpers, etc.)
• Understanding of series vs. parallel wiring
• Ability to properly seal roof penetrations

Professional installation typically costs $200-$500 depending on system complexity.

A complete RV solar system requires:

• Charge Controller: Regulates power flow to batteries (MPPT controllers are more efficient than PWM)
• Batteries: Store energy (lithium batteries are lighter and more efficient than lead-acid)
• Inverter: Converts DC power to AC for household appliances
• Mounting Hardware: Secures panels to your RV roof
• Wiring & Connectors: Connects system components
• Monitoring System: Tracks power production and consumption

Many of our recommended kits include most of these components.

Solar panels require minimal maintenance:

• Clean panels regularly with water and a soft brush
• Check for debris, especially after parking under trees
• Inspect wiring connections every 3-6 months
• Monitor system performance through your charge controller
• Check mounting hardware annually for tightness

Avoid harsh chemicals, abrasive materials, and pressure washers when cleaning panels.
