Why Should We Use Solar Security Light

Lights are an essential part of the community and workplaces. These lights provide security and safety to the people residing and working. The need for lighting is much higher in the most remote location where safety and security are a major concern. Solar security light has been known to be a popular choice for these remote locations. With no need for traditional power sources, these solar-powered security lights can be installed anywhere in any location. Below are some of the reasons that advocate the use of solar flood lights for security purposes.

Potential of providing clear visibility from a distance

The amount of light emitted by solar security lights is high enough to cover a large area. These solar-powered security lights also come with a motion sensor that can regulate the intensity of the light depending on people moving in or around the area, this helps in the conservation of power as the lights will only operate on high power when something moves in the area. This helps the lights capable of running all night long. Once the sensor detects the motion, the lights come on for a period of time allowing someone to visibly see what has set off the motion sensors.

Provide facial recognition at a certain distance

These solar security light with motion sensor has the ability to produce much better lighting and allows for better visibility since the lighting levels produced are close to the daylight as compared to any other types of lamps. This helps in providing facial recognition ability from a certain distance. This can be done by using any facial recognition system in place along with the floodlights or by any person who is responsible for the security of the area. These high levels of light allow people to recognize who is moving in their surrounding areas.

Protect the area from crime

One of the many reasons for using outdoor solar security lights is to use them to lower and control the crime rates in the area. Since the system doesn’t rely on the power grid, these lights are able to protect the area even when the power is out in the area. Criminals are not known to operate in areas where there is enough lighting and there is a fear of being caught. So, lighting the area helps deter crime in the area and also provide easy recognition if something bad happens.

Helps improve the nighttime pedestrian traffic and security

Having enough lightings foster positive changes in the people living in the area. An early morning jog, an after-dinner visit to the park or places, or late-night cycling is only possible when there is enough lighting available on the roads. The installation of more illumination makes people feel safe and secure.

For business owners, ensuring more customer traffic and adequate security for the employees is the most important concern. These outdoor solar security lights can help business owners achieve those objectives. No one wants to go to an area where there is not enough lighting available as people tend to feel unsafe.

Provide lighting to parking spots for the safety of the vehicle

It is mostly seen that the parking lots in communities are without light. Almost in every community, there is a pool, clubhouse, golf resort, and residence parking lots available. These parking lots need adequate lightings for the security of vehicles. Installing grid-powered lighting is costly but led solar security light is a perfect alternate to that solution. It provides higher levels of lighting without the additional need for cables and trenching.

 

Summing up, providing additional safety and security at night is the top priority, and using a good amount of lighting provides a feeling of safety for the people moving around and helps keep the area alive.

What Kind of Batteries are Used in Solar Street Lights?

One question that always delves into the minds of people when they switch to a solar street lights system is about the type of battery that will be used to power the solar street lights. Every user wants to get the best battery for their new solar light system that can save money, last longer, and requires the least amount of maintenance. With so many options out there in the market, some using confusing languages makes the choice difficult. It is important to know the kind of batteries, specifications, and their usage beforehand.

Knowing that all batteries are nor created equal, and many batteries are better in performance than others and some batteries in the market carry some danger to their operation. Let’s get into the kinds of batteries present in the market and some information about its specifications and battery profile.

Battery Type Size Nominal Voltage Voltage of Battery Set Cost Working temperature Cycle Life
Lithium-Ion (Li-ion) 18 x 65 mm 3.7V 12V Cheaper in price -30 to 65 Celsius 800 times
Lithium Iron Phosphate (LiFePO4) 26 x 65 mm 3.2V 12.8V More expensive -10 to 75 Celsius 2000 times
Lead Acid Battery 90 x 70 2V 12V Cheaper in price -20 to 5o Celsius 300 times

Lead Acid Battery:

People widely prefer using this battery because of the price advantages. It is inexpensive as compared to other batteries. However, there are some disadvantages compared to Li-ion and LiFEPO4. It needs frequent maintenance, the risk of explosion is high, and due to the presence of lead, it has some environmental concerns. The life of the battery is somewhere between 3 -4 years.

Another big disadvantage of lead-acid battery is that it needs a bigger solar panel for charging. The solar panel will have to generate at least 12 V to charge the battery. The battery size requirement for solar light application is not cost-effective. They are costly to manufacture which defeats the purpose of using inexpensive solar lights.

Lithium-Ion Battery:

Li-ion is a compact and high priced battery.  It requires a 3.7 V of power for charging. Which means the requirement of solar panel size is smaller. Even during cloudy days, the solar panel can still produce a 3 V and charge the battery.The life cycle of the battery is 4-5 years and it requires no maintenance.

One downside is that it is not favorable to extreme weather conditions. One of the kinds of lithium ion battery is the ternary lithium-ion battery. It uses Ni-Co lithium manganate as the positive electrode and graphite as the negative electrode material. The voltage platform of ternary lithium ion battery is very high, which means that the specific energy and specific power of it are larger under the same volume or weight. The ternary lithium battery is a 3.7V voltage platform, and the cycle life depends on different manufacturers, different models, and processes, and generally, it is 500-800 charge cycles. Below is the picture of ternary lithium ion battery pack.

 

Lithium Iron Phosphate Battery:

LiFEPO4 battery is a compact and priced higher compared to lead-acid and Li-ion battery. It is one of the most advanced battery types available in the market. It requires 3.2V of power for charging which means the requirement of solar panel size will be smaller.

li-ion battery

The life cycle of the battery of 6-10 years and requires no maintenance. Another advantage of this battery is that it can withstand extreme weather conditions.

How these batteries are used?

Lead acid batteries are generally used for lighting home and emergency conventional lights. Li-ion and Lithium-ion phosphate batteries are the best options for the solar lighting systems, especially used in all in one lighting system like solar street lights.

One of the important things to look out for in the battery is its capacity. Since the capacity is the measurement of the quantum energy that is stored in the battery.

7 Types of Solar Energy Applications

Before most of us were born, solar energy applications had been widely used.  In fact, not just 7 types of them, but many of them have a profound impact to us.

 

The first spacecraft to use solar panels was the Vanguard 1 satellite in 1958. The artificial satellite has taken advantage of solar energy. Mostly, it is because of the influence of Dr. Hanz Ziegler. It is a significant sign of science and technology. Although later Apollo space shuttle did not carry solar panel to finish the mission, people nowadays would rather believe that Apollo had been landed on the moon with the help of the solar system.

 

Here let’s take a look at 7 types of solar energy applications that have great influence to our life.
