Great alternative to traditional electric street lights are solar street light systems. These systems save maintenance and energy costs. Firstly, developed for remote areas with difficulties supplying electrical energy and areas with frequent electrical cuts and later for commonly used illumination of streets, parks, parking lots and other public areas.  Street lights are great consumers of energy and a lot of maintenance is needed for all the cities around the world, which costs a lot of money! Benefits of installing solar street lights are besides reduction of running costs and maintenance are also plain set up almost anywhere, very positive impact on the environment, no digging, wiring and other road works, no influence on lightning in case of power outages.

Before choosing solar product it’s very important that you know what kind of solar system is appropriate for your environment. Information you need to collect for the purpose of choosing optimal product are solar radiation, climatology at a given latitude, sunshine duration and hours of required illumination.

Only on that basis you should start selecting suitable solar lights. An important matter with reference to solar street lights is also the lamp. New LED technology ”lamps” have very long life, consume much less power than the metal halide or low pressure sodium lamps, LED’s cause smaller light pollution, the luminosity is adequate and solar LED’s allows smaller size of panels, batteries, chargers,..

Considering all above your street, park or parking lot can revive in better and environmental healthy light without endless concern of electrical bills and malfunctions.

Our way of life brought us so far, we have to count every cent we spend, and at the same time we want to be friendly to   environment for the purpose of saving nature and revitalize it for today’s and future generations.

Technology is developing with high speed and at this moment we have this great opportunity to use its result. One of the most useful, simple  and clean product invented is solar power. At this very moment outdoor solar lightning is most affordable option and it gives a lot of benefits to our homes and community.

Outdoor solar lights are practical from many aspects:

• An outdoor solar light doesn’t require any cables for installation purpose, that means that there is no facing problem of power cuts.
• It gives visibility equivalent to the conventional lightning, and all are extremely easy to use.
• There is a huge versatility of outdoor solar lights on the market, that can be used for yards, streets, security, camping, fountains, pools, walls and much more,
• Initial capital for outdoor solar lights is higher in comparison with commonly used lightning, but after some time, costs are lower, since there is no cost for electricity, cables, digging soil,…
• Environment is safe, since there’s no production of electrical energy and therefor no pollution.
• Buying outdoor solar light It is a one time investment.
• It means reduction of electric bills of housekeeping.

Outdoor solar lights usually uses LED bulbs ( light emitting diode ), which use very little power (they can function about 100,000 hours), so lights can stay illuminated longer with each charge. Ordinary solar led gives only 4 watts of light, newest super bright led technology enables solar led to give up to 50 watts of light. These lights are combination of several LED’s and forming them with special lenses and reflectors.

Solar light also includes battery which is charged during day with solar power. When charged it holds enough charge to power the bright LED up to 12 hours.

There are diverse models of solar lights therefor also different ways of charging:

• one panel charging single light,
• one panel charging several solar lights. Automatic on/off switch eliminates need for using timer

Firstly, some simple explanation of photovoltaic cell (solar cell), solar panel and solar energy, so we can get better view of the subject we are examining.

Photovoltaic (PV) cell is a composite of glass, usually two different types of semiconductors, junction in the middle, and two terminals on the outside (negative and positive). Joined number of cells form solar panel. When photons in sunlight hit the solar panel and are absorbed by semiconducting materials (such as silicon), negatively charged electrons are knocked loose from their atoms. This gives them independency of moving, and therefor they can stir in a single direction. Positively charged (protons) are moving in opposite direction. This interaction allows to capture solar energy for purpose of converting it into usable amount of direct current electricity.

Solar energy can be used in many applications, as for instance, water heating, heating, cooling and ventilation, cooking, process heating, vehicles, chemical, electrical generation and solar lightning.
