• Con: Still heavier than flexible alternatives
• Con: Requires flat mounting surface

Buyer’s Notes

Beyond matching a kit to your camping style, several factors deserve consideration before purchasing:

Warranty coverage varies significantly. Premium brands like Renogy and Go Power! typically offer 25-year panel output warranties and 5-year controller warranties. Budget options may provide shorter coverage periods—sometimes just 1-2 years on controllers. For full-time RVers, that extended warranty protection justifies the premium.

Controller compatibility matters. If you plan to expand your system later, ensure your charge controller can handle additional panels. A 60A MPPT controller paired with 800W of panels has headroom for future expansion; a 40A controller may already be near capacity.

Battery bank sizing is critical. An 800W solar array can produce 3,200-4,000Wh daily under ideal conditions. Your battery bank should be sized to store at least one full day’s harvest—typically 300-400Ah of lithium or 600-800Ah of lead-acid capacity.

Roof space requirements. Four 200W rigid panels typically require approximately 28-32 square feet of mounting area. Measure your available roof space carefully, accounting for vents, AC units, and antenna clearances.

Which One Should You Buy?

Your ideal 800W solar kit depends entirely on how you use your RV:

If you’re a dedicated boondocker who measures trips in weeks rather than days, invest in the Renogy 800W 12V General Off-Grid Kit. The premium MPPT controller, comprehensive warranty, and proven reliability justify the higher cost when your comfort depends on consistent power generation.

Weekend warriors and occasional campers should grab the Rich Solar 800W Kit. It covers the essentials without overspending, and the PWM efficiency trade-off barely matters when you’re plugging into shore power every few days anyway.

Cold-weather enthusiasts need the Go Power! 800W All-Electric Kit. Temperature-compensated charging and cold-rated components prevent the battery damage and underperformance that plague generic systems in freezing conditions.

Van lifers and minimalists prioritizing weight and space should choose the BougeRV 800W Flexible Kit. The weight savings are dramatic, and the ability to mount on curved surfaces opens installation options that rigid panels simply can’t match.

Safety & Common Mistakes

• Install a correctly sized fuse (typically 60-80A for 800W systems) within 12 inches of the battery positive terminal to protect against short circuits.
• Choose wire gauge appropriate for expected current and run length; for 800W systems, 8 AWG is minimum for runs under 10 feet, with 6 AWG preferred for longer distances. Target ≤3% voltage drop.
• Use proper battery and array disconnects; always de-energize the system completely before performing any maintenance or modifications.
• Double-check polarity before connecting any component—reversed polarity can instantly destroy charge controllers and other electronics.
• Secure all cables with strain relief and UV-resistant conduit where exposed to sunlight; unsecured wiring causes chafing failures and fire hazards.
• Never cover panels during installation without first disconnecting them; even partial sunlight generates enough voltage to cause shocks.

Always consult a qualified electrician if you’re uncertain about any aspect of your installation.

FAQs

• What can an 800 watt solar system actually run? An 800W system produces approximately 3,200-4,000Wh daily under good conditions. This comfortably powers a residential refrigerator (1,200-1,500Wh/day), laptop charging (200-400Wh/day), LED lighting (100-200Wh/day), phone charging, water pump, and entertainment systems. With careful management, you can also run a CPAP machine, small microwave (limited use), and 12V accessories indefinitely off-grid.
• Is there actually an 800W single solar panel? Currently, single panels max out around 400-450W for residential/RV applications. An “800W kit” consists of multiple panels—typically four 200W units or two 400W panels. Single high-wattage panels exist for commercial installations but are too large and heavy for RV roofs.
• Will MPPT controllers help in winter conditions? Absolutely. Cold temperatures increase panel voltage output significantly. MPPT controllers convert this higher voltage into usable charging current, typically yielding 15-30% more power than PWM controllers in winter conditions. This efficiency gain is most pronounced on cold, clear days when panels operate well below their rated temperature.
• Can I mix different panel brands in my 800W system? It’s technically possible but not recommended. Mismatched panels with different voltage and current characteristics force the system to operate at the lowest common denominator, reducing overall output. If you must mix panels, ensure they have similar Vmp (voltage at maximum power) ratings and use an MPPT controller, which handles variations better than PWM.
• How do I know if 800W is enough for my RV? Calculate your daily watt-hour consumption by listing all devices and their usage times. Multiply device wattage by hours used daily, then sum everything. Your solar system should produce 1.2-1.5× your daily consumption to account for cloudy days, inefficiencies, and seasonal variations. If your daily usage exceeds 2,500-3,000Wh, consider a larger system.
• Portable versus fixed panels—which works better for 800W systems? Fixed roof-mounted panels charge while driving, require no setup time, and handle all weather conditions automatically. Portable panels offer flexibility—you can park in shade while positioning panels in sunlight—and work well for renters who can’t modify their RV. For 800W systems, most users prefer fixed mounting due to the hassle of repeatedly deploying and securing four large portable panels.
