Small Solar Power Panels

Small Solar Panels: 50W to 200W Options for Batteries, Vans and Power Stations

Small solar panels do the jobs a full roof array is overkill for: keeping a trailer battery topped up over winter, running a gate opener or camera, charging a power station at a campsite, or adding 100W of solar to a van without touching the house wiring. In this range, the decision is less about efficiency and more about form: rigid, slim, flexible or folding, and whether a charge controller is already built in.

This collection holds 30 panels between 50W and 200W from Rich Solar, Sungold Power, Mango Power and Bluetti. Prices start from $69 for the Rich Solar MEGA 50 and top out around $430 for the 200W briefcase kit with a built-in controller.

How to choose a small solar panel

• What it charges. For a 12V lead or lithium battery, a rigid 12V panel plus a controller is the standard route; the Rich Solar MEGA 50W 12V Rigid Panel maintains a stored trailer or boat battery, while the MEGA 150W 12V Lightweight Panel carries a fridge and lights. For a portable power station, a folding panel with the station's connector, such as the BLUETTI 200W Monocrystalline Portable Solar Panel at 23.4% efficiency, is simpler.
• Controller included or not. Small solar panel kits with a built-in controller plug straight onto a battery. The Rich Solar MEGA 100W Briefcase carries a waterproof 10A controller inside its folding case. Bare panels need one added.
• Mounting surface. Flat roof: rigid. Narrow roof between vents: the 15.7-inch-wide MEGA 100 SLIM. Curved roof or deck: the MEGA 100W FLEX, which weighs 4.8 lb and bends to follow the surface.
• Voltage. Most of these are 12V nominal. The Sungold Power 100W 24V and 200W 48V kits and the Mango Power 200W 36V portable are for higher-voltage systems or specific stations, so read the voltage before buying.

Setup and usage tips

• Even a small solar panel system deserves a quick sizing check. The Solar Kit Calculator tells you whether 50W, 100W or 200W actually covers your daily use at your ZIP code.
• Never connect a bare panel to a battery without a controller. Only the briefcase kits carry one built in.
• Match the connector to the power station. Bluetti and Mango Power panels are designed around their own stations; check the input voltage range of any other station before mixing brands.
• Angle matters more on small arrays. A 100W panel lying flat in December produces a fraction of its rating; tilt it toward the sun or move it during the day.
• For winter storage, a 50W panel with a controller is usually enough to offset self-discharge and small parasitic loads on a stored RV or boat battery.

Frequently asked questions

What are the best small solar panels for a camper van? For a permanent mount, the Rich Solar MEGA 100 rigid, SLIM or FLEX depending on your roof. For a panel you deploy at camp, the 100W or 200W briefcase with the built-in controller.

Can a small photovoltaic panel run a fridge? A 12V compressor fridge typically needs more than 100W of panel plus a battery to carry it overnight. Plan on 150W to 200W and a battery of at least 100Ah for that job.

Do these panels work with any battery? The 12V panels work with 12V lead-acid or lithium through a suitable controller. The 24V, 36V and 48V panels are meant for matching higher-voltage systems or specific stations; check your controller's input range before pairing one with a 12V bank.

All panels ship free to the mainland US from brand partner warehouses, usually within a few business days, with 30-day returns. Call us with your battery and roof details and we will point you to the right size.
