200 watts is the minimum viable weekend setup, which is a real category and not a cut down version of a bigger one.

Who a 200 Watt Kit Suits
A 200 watt kit is the right starting point for weekend campers and van lifers who want to charge devices and run lights without paying for hookups.
It handles the modest loads of a short trip well, and it fits the limited roof space of a smaller rig or camper van.
If you run a refrigerator daily or want more headroom, step up to a 400 watt kit instead.
What a Complete Kit Includes
A complete 200 watt kit arrives as a matched set, which makes the install straightforward for a first time builder.
The panels
One 200 watt panel, or a pair of 100 watt panels when vents and hatches break up the roof.
A charge controller
An MPPT unit with headroom above 200 watts, so a later panel does not mean a second controller.
Wiring and connectors
Cable of the right gauge, a fuse, and connectors cut to length so nothing is guessed on the roof.
The battery
Around 100Ah of lithium, the bank that carries an evening without running the cells flat.
Which Kit to Buy
A1 SolarStore stocks complete RV solar kits, and its panel range includes Trina, Canadian Solar, and REC (stock verified August 2026), so you can buy a matched 200 watt package rather than piecing parts together.
Based on published specs and user reviews, look for monocrystalline panels, an MPPT charge controller with headroom for a later upgrade, and clear wiring instructions.
Free shipping applies on qualifying orders, and A1 ships from over 60 fulfillment centers (verified May 2026).

Battery Pairing and Output
Match 200 watts of panels with around 100Ah of lithium for roughly 1,200 watt hours of usable storage, which covers lights, charging, and a fan overnight.
In good sun, the array commonly produces around 600 to 800 watt hours a day. That figure moves with sun hours, angle, shade, and temperature, so plan around the lower end when the forecast is cloudy.
Most 200 watt users charge from 12V and USB and skip the inverter, which keeps the system simple and efficient.
When to Step Up
If your loads are growing, the honest answer on wattage depends on your daily watt hours.
Run the numbers in our RV solar system sizing guide, and if the total pushes past what 200 watts covers, move up to the 400 watt kit.

Meet the editorial team and our review standardsFrequently Asked Questions
Is 200 watts the smallest solar array worth fitting?
For camping off hookups it is the practical floor rather than a token panel.
In good sun a 200 watt array commonly produces around 600 to 800 watt hours a day, which is enough to keep lights, devices, and a fan going on a short trip.
What load breaks a 200 watt kit?
A 12V compressor refrigerator.
It draws around the clock instead of in short bursts, so it leaves little margin in a 600 to 800 watt hour day for anything else or for a run of cloudy weather.
Should I skip 200 watts and buy 400 watts instead?
Buy 400 watts now if a compressor refrigerator runs every day, if two people work from the rig, or if you camp under trees.
Stay at 200 watts if your trips are two or three nights and your loads are lights, charging, and a fan.
What battery matches a 200 watt array?
Around 100Ah of lithium, which is roughly 1,200 watt hours of usable storage.
That carries lights, charging, and a fan overnight, and the panels put back the next day what a light day took out.
Do I need an inverter with a 200 watt kit?
Only if you want household outlets, and most 200 watt setups do without one.
Charging from 12V and USB avoids the standby draw of an inverter, which matters more on a small array than on a large one.
Can I add panels to a 200 watt kit later?
Only if the charge controller was bought for the system you will end up with.
Choose an MPPT controller with headroom above 200 watts and leave clear roof space, and a third panel is a bolt on rather than a rebuild.
Is a 200 watt kit enough for a camper van?
For a van used at weekends it usually is, because the loads are as small as the roof.
Put a compressor refrigerator in that same van and you are back at the decision between 200 watts and 400 watts.
