LED lanterns on solar panels. Garden lights on solar panels (35 photos): Types of instruments and selection of design

We measured the power consumption of street garden lanterns on the solar panels, as well as the speed of charging on the straight sun, on a cloud day and in the shade. The picture turned out to be interesting, albeit quite expected.

This article says not so much about specific lanterns, but in general about the practical side of the operation of lamps on solar panels.

For the experiment, we took two inexpensive flashlights on solar panels. One of them is relatively new type (brown in the photo), which is now available at a price from 40 to 150 rubles. absolute majority. The second (black in the photo) is an old sample, which with the same high density inhabited shelves of shops several years ago at a similar price.

The main difference between the lanterns in the solar battery. And there it is a film type, but from different materials. Also in the old lantern was installed Ni-MH AA battery with a capacity of 600 mAh, while in the new it is smaller (AAA) and a capacity of only 100 mA · h. This is a natural depreciation, thanks to which the price of these lanterns after the dollar has changed not so much.

Energy consumption in both LEDs in the lanterns turned out to be the same and amounted to about 12 mA (~ 14 MW · h). This means that with a fully charged battery, a new flashlight will be able to work 8-9 hours, and the old (only in theory) 45-50. But it is important to remember that working in conditions of constant subwage (about it just below) Ni-Mh batteries quickly lose their capacity, because the more capacious battery in the old lantern would be preferable only from the point of view that it would work for a year a little longer.

Now we will deal with the power of panels and charging.

Solar Paper Charge Efficiency

To estimate the effectiveness of charging in different conditions, we chose a good day: the sun, which from time to time was closed with small light clouds. The lanterns were located both in an open place and in the shade of garden trees. Voltage and current measured on the terminals of batteries. The obtained values \u200b\u200bwere transferred to the amount of energy produced, expressed in MW · h. That's what we did:

The power of the solar battery at the old lantern turned out to be noticeably higher, but it is not so interesting. It is much more important, and this is a good news that with the direct sunlight, a small battery with a new flashlight can fully charge about 2.5-3 hours. And now bad news. If the flashlight is placed in the shade or day I got slightly cloud, then the charge efficiency will fall 10 times. And if in the sky clouds, then there is nothing to talk about. The battery will not charge.

For those who are interested in the details of our measurements of the operation of solar panels, we give a small sign.

conclusions

The lanterns showed themselves quite workable. New model On the straight sun is able to fully charge the built-in battery for about 3 hours, which will be enough to work for the built-in LED for 8-9 hours. The model of the old sample is more powerful and has a more capacious battery, but there is no point in reasoning about it, because There are no such sales for sale.

Another important momentThis is what the efficiency of the solar battery in cloud weather falls 10 times. And on a cloudy charge and stops at all. The same can be said about the placement of lanterns in the shade of trees, where, subject to sunny weather for a whole light day, they will not be able to charge their small battery even half, and if there is a light cloudiness, charging and stops.

Decorative garden lights on solar panels are no longer uncommon or deficit for residents of Moscow. Street lamps can be used not only to illuminate country sites, small tracks and households. The lighting devices will become an excellent decoration for the landscape, it is enough to successfully plan the design and choose the appropriate software. appearance model.

Stylish garden lights on solar panels

Luminaires on alternative power sources - a new solution in the world of energy efficiency and lighting. Such devices quickly convert standard solar radiation into powerful electrical energy, which will continue to be used to illuminate outdoor space.

Why is it relevant?

We offer in the range of lights on solar panels for cottage or country house with motion sensor. it convenient way Light the site economically, since the light will only turn on for need. If moving objects are not detected in the field of vision of automation, then there are no energy consumption. And also this thoughtful practice to acquire an additional element of protection. The submitted lamp is a serious problem for attackers and partly an assistant for a camera that can record what is happening on the illuminated area.

The possibility of using similar lighting devices on alternative energy sources is a weighty plus. Since such a device does not need charging from the rays of the sun. It will be quite easy to hit daylight.

We offer a solid range of devices that can be:

• Made in various stylistics;
• Have a mobile one;
• Become a part of the landscape composition.

Due to the solid body, the product is not afraid of precipitation, wind, temperature drops, ultraviolet. The lamp will look like presentable and stylish. We offer only those in their directory.

Manufacturers of modern lighting equipment offer not only standard lamps in a glass or plastic case, but also a variety of designer solutions in the form of colorful colors, animals and insects. If there is a desire to be beautiful and stylishly arrange a plot or a seamless territory, it is worth making a choice in favor of lamps, important advantages of which are:

• Big price range;
• A wide range of decorations and color solutions;
• Easy installation and the ability to install structures in any conditions.

In the range of lighting equipment there are models that may be included as a result of a pre-installed program in automatic mode. Separate lighting elements are installed at the base of the tracks, near the asphalt, at the base of the soil or on special stands. As soon as the dark time comes and it becomes dark on the street, the equipment is turned on automatically.

Today in the garden sites there are all lanterns or lamps that work on solar panels. Gardeners boldly apply them in landscape design and in the form of additional illumination of individual sections of the garden. Solar lamps are advisable to apply in those situations when there is no possibility to carry out electrical lighting or its arrangement is economically unprofitable.

How are the lights on solar panels?

In sunlights, you can highlight the following elements:

Solar battery under the influence of ultraviolet produces electricity And it charges the battery, which in turn in the dark feeds the LED.

For complete charge Battery solar lights work 8 ocloc'k. Moreover, the work of the lamp does not depend on weather conditions, because ultraviolet penetrates through the clouds. Only late in the fall, the lantern battery can not charge completely. This is due to the fact that the light day becomes shorter. Even in such conditions, the lamps will work, the truth is slightly smaller.

The main characteristics of garden solar lamps

Solar lights can be combined into three groups according to the following characteristics:

Benefits of garden lamps on solar panels

disadvantages Garden solar lamps:

• required clean on the winter, since they do not have a battery from low temperatures (the exception is garden lights);
• lamp during charging it is advisable to install So that direct sunlight fell on it;
• more suitable for decorative lighting;
• lamps are enough expensive.

Installation and operation of garden solar lamps

Installing garden lamps is very simple. To install on a flat surface, it is necessary to use lamps with a special leg. If the lantern of the leg is made in the form kolyka, then it is sticking to the ground. In solid soil, it is first necessary to dig a deepening, then put the lantern in it and carefully tackle the Earth from all sides. You can not use a hammer and gross power. The lamp will break from it.

Via solar lanterns You can allocate:

Caring for lamps is to periodically wipe the dust from them, remove dirt and remove for the winter to the house. Despite the fact that solar lamps very reliablemay have the need for their fixing. First you need to check the charge level of the solar battery and only then turn on. If the light is not turned on, you need to check the battery. To do this, go into a darkened room and check the soldering places. When the damaged wiring is detected, it must be soldered using cold welding. If the repair results are missing or are minor, it is necessary to replace the solar battery.

Sadden lamps on solar panels can be an excellent alternative to electric lighting in remote areas of the garden. A variety of forms, colors, sizes allows you to use them in landscape design. Made in the form of the figures of the gnomes or animals they are excellent complete Alpine Gorka. In the dark, such lanterns not only focus on beautiful corners of the garden. Silvering the steps, you can climb or go down the stairs without fear of falling. Lanterns can be arranged by groups or chaotically. What method to choose - depends only on the preferences of the owner of the site.
