What 111 W means on a small installation
A 111 W module will not run a house, but it is often enough to keep the battery of a modest system in good shape. This SUNBEAMSystem Tough shows it in a 106 x 54 cm format weighing only 2.5 kg, a weight that is easy to handle on your own, even on a ladder or a pontoon. Its flexible build and its eyelets make it a handy tool for surfaces where a framed panel would be too tall or too heavy.
Estimating your need before fitting
- List the devices connected to the battery and what they draw.
- Estimate how long each one runs per day.
- Compare that total with the plausible output of a 111 W module for your season and region.
- If the gap is large, plan a second module or another source.
This approach applies equally to a private user and to a professional equipping a technical room or a site trailer.
A format designed to adapt
The material is a flexible plastic, protected against the weather according to the data sheet. The cells are monocrystalline Sunpower, with a stated efficiency above 22.5%. Eyelets of 6 x 6 mm allow mechanical fixing, and a flush 1.5 m cable leaves the panel.
Fitting and wiring
Before fixing, hold the panel in place and follow the path of the sun to confirm that nothing shades it during the useful hours. Choose fasteners compatible with the eyelets and suited to the environment: damp, sea spray or heat can wear them faster than expected. The cable plugs into a charge controller; check that it suits your battery voltage and the module’s values. Work on a distribution board or a household network should be left to a qualified installer.

Safety advice
A cable dragging across an abrasive surface will eventually wear through: secure it with clips. Never join the two conductors together in daylight, and disconnect the controller before changing the wiring. Avoid standing on the module to fix it or to get past.
Routine care
Once or twice a season, wipe the front with a damp cloth and inspect the eyelets and fasteners. When the module is not in use, store it flat and dry, away from anything sharp.
