If there is one area where solar energy goes without saying, it is good to light the outside. 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.
Advantages and disadvantages of solar garden lights
The first advantage of solar outdoor lighting is to combine ecology and economy. Indeed, it allows you to illuminate your garden without spending a euro in electricity. On the other hand, to possess a good quality lighting, you will have to invest in good material. Small tags to a few euros, so cute they are not enough...
Fortunately, the choice of solar lighting is as vast as it is aesthetic:
- Solar Beacons and Pucks all colors to highlight an alley or the edge of a terrace.
- Solar terminals or lamp post to light the path leading to the front door or to illuminate the terrace.
- Solar projector for powerful lighting.
- Solar spots on stakes or recessed to emphasize the massifs, a beautiful shrub, etc.
- Wall lamp to install on the wall.
- For the fun of kids and grown-ups, there are solar lights in the form of butterflies, flowers, animals, etc. or solar LED garlands.
Solar lighting is autonomous see nomadic. There is no connection to provide and sheath to bury. And in addition, it turns on all alone at dusk! However, as we mentioned, it is a source of light pollution.
Obsolete solar lamps have to be considered as electronic waste. You should not throw them in the garbage bin because they contain polluting metals.
Solar outdoor lighting is therefore a very interesting ecological choice as long as you comply with the rules on light pollution and waste recycling.
