During the day, the sun gives its benefits to your plants and at night, always thanks to him your garden shines a thousand lights! But how to choose a solar garden lamp and organize solar lighting efficient and environmentally friendly?

The criteria for choosing a solar garden lamp

The solar lights are luminaires with a small photovoltaic panel that captures solar radiation. This energy is stored in a small battery and at night, it feeds an LED lamp.

It is therefore important that you choose sunny places to install your lamps. Be careful, the earth revolves around the sun and the shadows too! What is in the sun in the morning, may be in the shade in the afternoon...

Fortunately, you can find solar lights with a remote sensor. You install it in the sunniest place and it feeds with a wire, one or more lamps that can be located in the shade during the day.

And amorphous silicon sensors, have the advantage of being able to operate even when the weather is cloudy.

Be careful also to the quality of the photovoltaic sensors and that of the battery. Lamps sold inexpensively have a life of only 2 or 3 years. On some high-end luminaires, the batteries are interchangeable and protected against the harmful effects of a total discharge.

Check that the surface protecting the solar panel has received a UV treatmentthis will prolong its life.

For optimal lighting, choose sufficient power and autonomy:

  • 12 W of power au minimum.
  • A autonomy of at least ten hours in summer after a day of charging and about 2 to 3 hours in winter.

Some solar garden lights have a Twilight release, a presence detector and a switch. These are not just unimportant gadgets, quite the opposite. Because solar lights that turn on alone at dusk are also a source of light pollution by staying illuminated for several hours. To be able to extinguish them or to foresee that they will only be triggered when a person passes, is an important ecological gesture.
