Straight answers, no throat-clearing.
How much solar do I need for my RV?
Add up your daily watt-hours (every appliance's watts x hours used), divide by your area's peak sun hours, then add about 25% margin. A 400W array covers the basics for most couples; full-timers running air conditioning often land at 1,000W or more. Our estimator above does this math for you.
What size generator do I need for a 30 amp RV?
A 3,500 to 4,000-watt generator is the standard answer. 30-amp service tops out at 3,600W, and that range starts a typical 13,500 BTU roof air conditioner while leaving headroom for a fridge and chargers.
What size generator do I need for my camper?
List your must-run appliances and note the highest start-up watts, not just running watts. A roof AC needs roughly 2,800 to 3,000 starting watts; everything else in a basic camper usually fits under 1,000. Size the generator to the AC if you run one.
Can I use 435W residential solar panels on my RV?
Yes, electrically they work fine, but check three things: roof space (they're large, around 40 x 70 inches), weight, and your charge controller's voltage limits. Many RVers prefer 100W to 200W 12V panels because they fit roofs better and wire more simply.
Can a solar panel run my RV air conditioner?
One panel, no. A system can, but it needs to be big: expect 1,200W+ of panels, a 3,000W inverter and a large lithium bank for a few hours of AC. That's why most boondockers run the AC off a quiet generator and let solar handle everything else.
How do I install solar panels on my RV roof?
Most installs use Z-brackets or tilt mounts screwed into the roof (sealed with lap sealant), panels wired in series or parallel to a charge controller, then to the battery bank. If drilling into your roof makes you nervous, suitcase-style portable panels need no installation at all.
How much does RV solar installation cost?
DIY kits run a few hundred dollars for a basic 200W setup to $2,000+ for a complete 800W lithium system. Professional installation typically adds $500 to $2,000 in labor depending on system size and roof complexity.
Do I need an inverter generator for my RV?
If you camp around other people, yes. Inverter generators are dramatically quieter than open-frame models and produce clean power that's safe for laptops and phones. They're the default choice for campgrounds with noise rules.
What's the quietest type of generator for RV camping?
Inverter generators in the 2,000 to 3,500-watt class are the quietest fuel option, often rated in the high 50s dB at quarter load. For true silence, a portable power station (a big lithium battery with an inverter) makes no noise at all but stores far less energy.
30 amp vs 50 amp: which generator do I need?
Match your RV's shore plug. 30-amp rigs need up to 3,600W; 50-amp rigs can draw up to 12,000W across two legs, so they typically pair with 5,500W+ generators or two paralleled inverters. When in doubt, check the plug on your power cord.
Can I run my RV generator while driving?
Built-in onboard generators are designed for exactly that and commonly run the roof AC while rolling. Portable generators should be secured, ventilated and never run inside the vehicle or an enclosed compartment due to carbon monoxide risk.
Solar vs generator for RV: which is better?
They solve different problems. Solar is silent, free to run and handles daily loads; generators deliver big power on demand regardless of weather. Most serious boondockers run both: solar as the daily driver, a quiet inverter generator for AC and cloudy stretches.
Should I build a 12V, 24V or 48V RV solar system?
12V for most people. It matches your RV's existing 12V wiring and keeps parts easy to find. Step up to 24V around 1,000 to 3,000W of panels, and 48V beyond that, where thinner wiring and lower losses pay off. Higher voltage means specialized components, so only go there when the system size justifies it.
