• 1.How to find the perfect solar garden light for me?

    Before you begin to choose what types of solar garden light you need, be sure to bear in mind that due to the limited efficiency of solar power, the solar light is not effective as the electric 110-240V lights. Solar light does not have a high light intensity and capable of illuminating your whole garden area or entire driveway. But with proper set up, solar garden light is adequate to see what is around you, avoid stumbling around in the driveway trying to navigate your way to the front door, or slipping on the dog's chew toy and the kids' bikes; or maybe you're having a garden party and you want to show off your yard at its best.

  • 2.How many types of solar garden lights that i can choose?

    There are several types of solar garden light that you can choose from:  solar spotlight,  solar wall light,  solar security light(with motion sensor),solar lighting system and solar courtyard light.  Solar Spotlights:  Solar spotlight has a narrow window to emit the light and many reflectors to maximize the lumen output, thus it is much brighter on a spot of light and able to light up a longer distance. Solar spot lights are perfect for highlighting a particular feature in your yard, whether it's a tree or your favorite part of the garden. If you want a wider glow to be cast in the area, set up several pairs of solar light in a line or a circle. They make it easy to illuminate areas like the front porch, the garage or the driveway without the added energy cost and setting up the wires that comes with traditional lighting. Solar Wall Lights: It is obvious that solar wall light has a base that is mounted to wall, fences, or any vertical flat surface. The up side of solar wall light is that it has the widest applications, exterior walls, fences, doors, etc. The down side is that, at the most parts of the world, the walls would also cast a shadow on the solar light, the light would not be charged a full day. Thus many solar wall lights have a seperated solar panel, or has a PIR sensor to save the energy.  Solar Motion Light:  Solar security light, we can also name it as Solar Security Light/Solar Sensor Light, a solar motion light comes with a motion sensor that detects movements within its vicinity and triggers the light to illuminate the area.  A solar motion light insures the security of your home by serving as a physical deterrent to thieves. The motion sensor and automatic turn-on of lights puts them at risk of getting caught and apprehended. Since getting caught is the last thing that they want, they are more likely to move on to the next house with no alarm or security light system. You have the choice to place your solar lights at different places outside of your house or office as every scenario is possible. You can use them to beautify your garden and garage at night. These are the same solar lights that are found in runways, airports, flag poles or even your street lights. Here is the list of possible places to install them: • Garage • Entrance of your house • Patio (pool and back) • Mail box • Driveway • Porch Solar Lighting System(for home use): Unlike other solar lights, solar lighting system is actually applied for indoor use. The solar system always consists of solar panel, rechargeable batery, control box, DC to AC invert, wires, hardware accessories etc. The power of the system varies from 5W to 5000W   The factors that you would need to concern Light intensity  If you're after a garden light that will actually light up an area, you'll need one with a high light intensity.  Screw-in placement  Screwing in lights makes them more secure. Otherwise garden lights can be easily pulled out and stolen.  Complete kit  Buying your lights in multiple pack.  Separate solar panel  A separate solar panel will make it easier for you to use solar lights in shaded areas – you can position the panel in the sun.  Battery life  Battery and solar panel life generally reduces with continual use in a garden. Bear this in mind if you're buying a battery-powered 12V garden light or a solar-powered garden light, and choose one that will last longer if possible.  Motion sensor  This is useful for temporarily lighting up an area more substantially when something passes by; it's useful for extra security (i.e. foiling sneaky burglars) and also if you have people in the house who just can't remember to turn off switches...  Light sensor  A dusk/dawn sensor detects the light level, and turns on the garden light when it gets low.

  • 3.How do you install garden lights?

    Here comes the easiest step, once purchased and received the solar lights, simply pick up the location that you need some lighting, and install the solar lights.   Installing most solar garden lights usually involves pushing or screwing the lantern into the upright post and then inserting the whole assembly in the ground. The ground may have to be watered first to make sure the stake can be driven in easily.  How much do you need to pay?  From $5 to more than $200 per light.

  • 4.What information you should give us to make offer of solar street lights?

    1.The sunshine hours per day or the exact city where the solar street light will be installed. 2.What is the max continuous rainy days in the raining season there? (It matters because we have to make sure the light can still work in 3 or 4 raining days with little sunshine). 3.The brightness of LED lamp(50Watt, for example). 4.Working time of solar street light every day(10 hours, for example). 5.The height of the poles, or the width of road. 6.It is better to offer the pictures on the locations where the solar street light going to be installed.

  • 5.What is a sun hour?

    A sun hour is a unit of measurement of the intensity of sunlight on the earth at a given time that can be used for generation of solar power, recognizing factors such as climate and weather. A full sun hour is measured as the intensity of sunlight at noon, whereas less than a full sun hour will result during the hours before and after noon.

  • 6.Which types of warranties you will have?

    Solar Panel: mininum 25 years of power generation capacity, with 10 years warranty. LED Light: Mininum 50.000 hours life span, with 2-year all inclusive warranty - covers everything on the LED street lights, including lamp holder parts, power supply, radiator, scaling gasket, LED modules & lens. Battery: 5 to 7 years life span, with a 2-year warranty. Controller inverter and all the electronic parts: Minimum 8 years by ordinary usage, with a 2 year warranty. Pole solar panel bracket and all the metal parts: up to 10 years life span

  • 7.What happens if there are cloudy days?

    Electrical energy is stored in the battery each day, and some of that energy is used to operate the light at night. Generally, we design your system so that the battery will operate the light for five nights without charging. This means that, even after a series of cloudy days, there will be plenty energy in the battery to power the light each night. Also, the solar panel will continue to charge the battery (although at a reduced rate) even when it is cloudy.

  • 8.How does the light know when to turn on and turn off?

    Joy Solar’ s solar controller uses a photocell and/or timer to control when the light will turn on, when the sun goes down, and to turn off when the sun comes up. The photocell detects when the sun comes down and when the sun comes up again. Joy Solar can make the lamp last anywhere from 8-14 hours, and this varies on the customer’s needs. The solar controller utilizes an internal timer that is pre-set for a specific number of hours to determine when to switch the light off. If the solar controller is set to leave the light on until dawn, it determines when the sun rise (and when to switch the light off) by means of voltage readings from the solar panel array.

  • 9.What is the typical maintenance schedule for a solar lighting system?

    There is no regular maintenance required for a solar lighting system. However, it is helpful to keep the solar panels clean, especially in a dusty climate.

  • 10.Why Joy Solar advises to use 24V for 40+W Solar LED System?

    Our suggestion for using 24V battery bank for solar LED system is based on our research which we conducted earlier before launching our Solar LED system. What we did in our research was that we actually tested both the systems 12V battery bank and as well as 24V battery bank. Finally we find 24v battery bank have better performance. Our suggestion for using 24V battery bank for solar LED system is based on our research which we conducted earlier before launching our Solar LED system. What we did in our research was that we actually tested both the systems 12V battery bank and as well as 24V battery bank. 1. When LED power is 40W and is associated with 12V battery system, the whole power consumption including controller and everything is around 48W to 50W. 2. And is the scenario of LED power of 40W and connected with 24V battery system, the whole power consumption including controller and everything associated with the system is measured around 42W – 43W. After conducting the test we can conclude that, there will be a difference of 13% in the power efficiency, so we strongly advise you to go for 24V system for 40+ W solar LED systems. For power above than 40W, it is beneficial to install 24V battery bank because it is much better in efficiency and it also saves electrical energy greatly. Technical Perspective: There is a basic formula for calculating it is: P=UI, which means POWER=Current (A) * Voltage (V) So when the power is 40W and you have a battery bank of 12V then the current will be 40W/12V = 3.33A and if you have 24V battery bank then the current is 40W/24V = 1.67A this mean 24V battery bank is just half of 12V system. Less current goes through the wires, automatically the power consumption would be less hence less power lost during the transmission. What are the advantages of 24V LEDs over 12V LEDs? LEDs driven by 24V drivers have longer permissible distances between light source and driver as compared to 12V DC LEDs. 12V LEDs are usually suitable for applications where low light outputs are required. 24V LEDs offer products with higher outputs than 12V products. If you need more information please, don’t hesitate to contact us. Our staff will be glad to help you in any your requirements.

  • 11.What do we need to know to customize your solar light project?

    In order to customize your solar street light project, the first thing we need to focus on is the location for installing the solar power lighting system and the perfect location where you want to install your solar light project, because different locations and surface have different levels of sunlight which can have an impact on the outcome of the solar light project.  How to calculate solar panels size? In order to customize your solar light project the first thing we need to focus on is the location for installing the solar power lighting system and the perfect location where you want to install your solar light project, because different locations and surface have different levels of sunlight which can have an impact on the outcome of the solar light project. If you tell us the location where you want to install the solar LED systems, we can estimate the irradiation to calculate the solar panel size. How to Calculate the pole height for solar lighting? Pole height is calculated by having an estimate of the road width, what is the for solar LED lighting system pole’s height? In this case we are always willing to help you out if you will tell us the road width where the solar street light will be installed we can evaluate the pole height plus lamp power (type of road, lux). Do you have any ideas of the type of road (highway, main road, village road) or do you have any minimum lux requirement? We need them to calculate the pole height and lamp power accordingly. Batteries (backup time): Do you know the battery capacity required? In order to calculate it, we need to know how many everyday working hours the light you want? How many estimated rainy or cloudy days you usually have in your location? How long you need maximum power light and how many hours/day you need power save mode (example 6 hours full power, 6 hour 50% power everyday)? Every aspect should be kept in mind and carefully execute the method while installing the solar light project.If you have a need to install it more quickly, please let us know. If you need more information please, don’t hesitate to contact us. Our staff will be glad to help you in any your requirements.

  • 12.Do I have to charge the batteries?

    Batteries are shipped 85% charged. The batteries will be at 100% charged within two weeks of proper operation.

  • 13.What is a Gel Battery (VRLA Battery)?

    Gel battery also known as VRLA (valve regulated lead-acid) batteries or gel cells, contains acid that has been gelled by the addition of silica gel, turning the acid into a solid mass that looks like gooey Jell-O. They contain less acid than a regular battery. Gel batteries are commonly used in wheelchairs, golf carts and marine applications.There are several advantages to using gel batteries.  Gel Battery Advantages / Features: Maintenance Free Less maintenance means more time for relaxation. They are maintenance free. Since the battery system is designed to eliminate the emission of gases, the volume of free electrolyte (battery acid) that could be released is very small. There is, therefore, no need to check the level of the electrolyte or top off water lost due to electrolysis. Leak-Proof Battery No leaks mean no rust. The VRLA batteries are leak-proof and will not leak even if the container is cracked or broken. In these sealed lead-acid batteries, a glass-mat separator absorbs the electrolyte and holds it between the lead plates. Because the acid electrolyte is held by the absorbent mat, the battery will not leak or spill. Rechargeable with a proper Battery Charger Using the right charger is required with Gel Cell batteries Gel or VRLA battery requires no maintenance once the charging system has been properly set up. It is finicky when it comes to being recharged, so it is important that the correct battery charger be used on a gel cell battery, otherwise poor performance may result. Additional Safety Gear not Required Shipping gel cell batteries is simple and safe Gel or VRLA battery requires no maintenance once the charging system has been properly set up. It is finicky when it comes to being recharged, so it is important that the correct battery charger be used on a gel cell battery, otherwise poor performance may result. Easy Operation in Most Temperatures Wrap up and enjoy the outdoors without worrying about battery failure The VRLA batteries can operate in a variety of temperatures from very high to very low (between -40 degrees Fahrenheit to 140 degrees Fahrenheit) and may last a bit longer in hot weather applications than other batteries. Worry -Free, Heat and Shock Resistant They are non-corrosive so there is no worry about sulfuric acid leaking from it Because plastic cases of VRLA batteries are ruggedly built, these batteries can also withstand vibration, heat and shock.

  • 14.What are Solar Lights?

    If Scientifically define, Solar lights are portable light fixtures composed of LED lamps, photovoltaic solar panels, and rechargeable batteries.

  • 15.How many hours need to install Solar/Wind Led street light?

    Installing a solar or wind powered LED street light isn’t any sort of rocket science, in fact anyone willing to install by himself can do it easily.  Step 1: Dig the installation hole Once you have decided where you want to place your solar or wind LED street light, you need to make sure you have dug the hole properly in the ground. But how would you do it? Well, there are two possible options for digging the hole. 1. If you go with the excavator then it would only be going to take around 2-3 minutes and you are done. 2. The other option is manually digging the hole by shovel if there’s only one man doing the job it would going to take one hour to complete the job. Step 2: Make the concrete foundation kits This process needs cement because a proper foundation needs to lay down in order to hold the street pole strongly. This process will take around 20 minutes if done by one person. Step 3: Make the wire connections This task needs concentration, making sure you have properly connected all the wires with the lights and the battery. If you’re doing it alone it will take your 20 minutes. Step 4: Fix the pole to the foundation kits The last step towards installing a solar or wind LED street light is to fix the pole in the foundation which you have dogged for. Try to fix the solar or wind-powered streetlight accurately, because, if in case you do something wrong you have to do it again. This process is for 5-7 minutes if done with the help of a crane and 2 men. On contrary, if you’re going to do it by hand, this will take around 15-20 minutes. Beside this, you will also need at least four to five men to help you out in installing it properly. In short, the complete installation will not take longer than 2 hours if done properly and stepwise. If you need more information, please don't hesitate to contact us. Our staff will be glad to help you in any your requirements.
