As you know that solar lights have great use in the industry. The basic reason is that they are always cost effective as well as reliable for a long time. So progressive countries always rely on solar lights to fulfill their energy needs. Specially in generating electricity, they are great resource. Now, they are becoming the part of human’s life. From your home till large electricity projects, solar lights are everywhere now. Here are the given top reasons that why people prefer to buy solar lights for their different uses.
First of all, solar lights help to reduce carbon dioxide gas. Also, they are simple and easy to install almost anywhere like home, lawn, gardens, patio, gazebos, fences, walls, driveways, etc. They are charged from sun at the day time without any cost and spending electricity. If you full time charge them in the sunlight then they can last up to six hours which are enough for the needs of a single day. You can not only fix them but also change their positions anytime you want. From solar lights, you can charge your windows even their blinds too.
Solar lights designed for specific purposes such as runways and driveways, don’t need any wiring, cabling or placement issues. One more important benefit is that solar lights have very little or sometimes no need of repairing or maintenance. Minimum life of solar lights are till 1 year. They are used at any place where sunlight is available. Mostly, they are ideal for outdoor purpose such as occasions, festivals, camping, etc. Solar street lights are also made to keep the environment clean and free from any type of negative and harmful rays of electricity as well as sun.

Solar Security Lights – Best To Keep Your Place Safe
Do you have a plan to insert outdoor solar lights outside your home? Think that if they can safe your home then how will be it? Definitely you can use solar security lights for security purpose. People normally think that there is no difference between solar flood lights and solar security lights but they are different. So first we have to clear our concept about the difference between these two. The solar flood light remains work as long as it is turned on. While, a solar security light is a kind of flood light but it has a passive infrared sensor that detects movement. This light is turned on only when the sensor activates it. This activation is usually remains on for only one minute. But some other models of this light are also available in the market whose activation time is till upto 10 minutes.
So this is a very important feature for security purpose that light is turned on automatically when it is activated by the sensor. You can charge its battery at the day time. Although, it is turned on anytime when activated but in spite of this, it is not get dim. Normally, solar security lights are designed with a small solar panel which is connected by a wire to that light. Solar security lights are available in the market with different lengths of wire but the ideal length you have to choose is 15 feet (atleast). Due to this ideal length, you have a big flexibility of inserting your light where ever you want.
Not only for home, solar security lights can also be used to make any place secure which you want. But one thing you have to remember that insert them in such places where it can absorb proper sun light. Otherwise you will not avail benefit completely from that lights. Solar security lights are a viable option for the security purpose of different places. The major advantage of these lights is that they still works during a power interruption. Also, one more thing keep in your mind, the intensity of light. If you want these lights more brighter, try to buy halogen bulb models. But also try the LED models as well because they can also provide you a good brightness of light.

Solar lights
Solar lights are widely used in different applications. They are very reliable due to their healthy effect, low consumption power and cheap cost. One of the most beneficial applications of solar lights is solar exterior wall lights. These lights are used on the outside walls of your home. They are fixed in the form of bulb at the outside corner of the walls. They provide a bright and beautiful view to the outer structure of your home at night. Basically solar exterior wall lights have many options in the bulb configuration which you can use. But your source of light is single then dual bulbs are required.
In solar exterior wall lights, the light source is LED bulbs because their brightness if so clear and same as any type of fluorescent bulbs. These lights have a long life and also they don’t create heat. That’s why you can easily them in different areas without any worry, damage and fear. Actually the majority of these lights have a range of sensors. It means that they can be fixed with onboard timers, different sensors as well as motion sensors too. These qualities become solar exterior wall lights the best solution for safety and security in the home as well as business environments.

Amorphous Silicon Solar Cells
The efficiency of amorphous solar cells is typically between 6 and 8%. The Lifetime of amorphous cells is shorter than the lifetime of crystalline cells. Amorphous cells have current density of up to 15 mA/cm2, and the voltage of the cell without connected load of 0.8 V, which is more compared to crystalline cells. Their spectral response reaches maximum at the wavelengths of blue light therefore, the ideal light source for amorphous solar cells is fluorescent lamp.
Crystalline Silicon Solar Cells
Among all kinds of solar cells we describe silicon solar cells only, for they are the most widely used. Their efficiency is limited due to several factors. The energy of photons decreases at higher wavelengths. The highest wavelength when the energy of photon is still big enough to produce free electrons is 1.15 μm (valid for silicon only). Radiation with higher wavelength causes only heating up of solar cell and does not produce any electrical current. Each photon can cause only production of one electron-hole pair. So even at lower wavelengths many photons do not produce any electron-hole pairs, yet they effect on increasing solar cell temperature. The highest efficiency of silicon solar cell is around 23 %, by some other semi-conductor materials up to 30 %, which is dependent on wavelength and semiconductor material. Self loses are caused by metal contacts on the upper side of a solar cell, solar cell resistance and due to solar radiation reflectance on the upper side (glass) of a solar cell. Crystalline solar cells are usually wafers, about 0.3 mm thick, sawn from Si ingot with diameter of 10 to 15 cm. They generate approximately 35 mA of current per cm2 area (together up to 2 A/cell) at voltage of 550 mV at full illumination. Lab solar cells have the efficiency of up to 20 %, and classically produced solar cells up to 15 %.
