Types of solar lighting best suited for cities
1. Solar Street Lights: Perhaps the most common type of solar lighting in cities, solar street lights provide illumination for streets, sidewalks, and other public spaces. They’re self-contained units that can provide reliable lighting without the need for traditional power sources.
2. Solar Parking Lot Lights: These lights can be installed in parking lots to provide security and visibility at night. They can often be programmed to turn on at dusk and turn off at dawn, or use motion sensors to conserve energy when the lot is empty.
3. Solar Pathway Lights: These are smaller lights often used in parks, along walkways, or in gardens. They’re typically easy to install and can create a pleasant ambiance as well as enhance safety.
4. Solar Flood Lights: For areas that require more intense light, such as sports fields or large public areas, solar flood lights can provide powerful illumination. Some models are equipped with motion sensors and can be a good choice for enhancing security.
5. Solar Sign Lights: These are designed to illuminate signs and billboards. They help ensure that important information can be seen even at night.
6. Solar Deck Lights: Commonly used in public outdoor seating areas, these lights add a warm, inviting glow and increase visibility and safety.
Each type of solar light has its own advantages and is suited to different applications. When choosing solar lighting for a city, it’s important to consider factors like the local climate (to ensure the solar panels receive enough sunlight) and the specific lighting needs of each area.
Steps cities can take to start using solar lighting
1. Determine areas to be illuminated: First, the city needs to determine which streets or public areas need to be fitted with solar streetlights. This can be done through site visits and data analysis.
2. Design and planning: the city then needs to design and plan the solar lighting system. This includes selecting the right model of solar lights, determining where to install them, and developing a detailed implementation plan.
3. Installation and testing: Once the design and planning is complete, the city can begin purchasing the equipment and installing it. Once the installation is complete, testing needs to be done to ensure that all equipment is working properly.
4. Education and outreach: In order to encourage more people to use solar energy, cities can also conduct education and outreach campaigns. For example, online information platforms can be used to explain the benefits of solar energy to community members and dispel their misconceptions about solar energy.
In addition, some cities have demonstrated that solar lighting can be used not only for streets and public areas, but also to support commercial and community development. And, as long as there is enough sunlight, solar streetlights can be installed on any street, whether it’s a busy city street or a remote rural area.
Advantages of installing solar lights in urban areas
Installing solar lights in urban areas comes with a multitude of advantages:
1. Positive Environmental Impact: Solar lights use renewable energy from the sun, which helps to reduce carbon emissions and combat climate change. They are a clean, green, and sustainable lighting solution.
2. Smarter Technology: Many solar lights come equipped with smart features like motion sensors and automatic on/off functionality. This can enhance the efficiency and effectiveness of urban lighting systems.
3. Cost-Effectiveness: While there may be an initial investment, solar lights can lead to significant savings over time due to their low maintenance costs and the fact that they don’t rely on grid electricity. This makes them a financially smart choice for cities.
4. Increased Lifespan: Solar lights are durable and have a longer lifespan than conventional lighting solutions. This can result in additional cost savings and less waste in the long run .
5. Improved Community Aesthetics and Safety: High-quality LED lighting from solar lights can enhance the look of urban neighborhoods and improve visibility for pedestrians and drivers. Moreover, they function even during power blackouts, ensuring consistent illumination.
6. Energy Conservation: Solar lights conserve energy by harnessing sunlight during the day and using it to light up streets at night. This reduces reliance on the grid and contributes to energy conservation efforts.
Disadvantages of using traditional street lighting over solar powered alternatives
Pros:
Eco-friendly: Solar street lights use renewable energy, which is harmless to the environment and more environmentally friendly than traditional street lights.
Low maintenance costs: Solar street lights have low maintenance costs. Since there are no external wires, the risk of accidents is minimised. In contrast, traditional street lights require regular replacement of bulbs and wires, which is more costly to maintain.
Energy Saving: Solar street lights do not require additional electricity, which saves energy.
Safety: while traditional street lights may have potential safety hazards due to aging materials, construction quality and power supply issues, solar street lights are safer.
Disadvantages:
High initial installation costs: although solar streetlights have lower long-term maintenance costs, their initial installation costs can be higher than traditional streetlights.
Dependence on sunlight: solar street lights depend on sunlight to work. In conditions where there is a shortage of sunlight or cold temperatures, the utility of solar street lights may be reduced. As a result, you may also need utility-powered lights with motion sensors installed as supplemental lighting.
Structural Integrity Issues: In the solar lighting industry, we see two major issues: lack of wind loading and structural integrity. This can lead to problems.

Project Background
This is our company’s US partner implementing a lighting project in a local farm. At that time, the original solar lighting equipment outside the farm owner’s house was old and not bright enough, and some of the lamps were damaged and not working properly. In order to improve the lighting effect farm owners decided to replace the lighting equipment. To quickly replace the equipment, solar lights are still the preferred solution for farm lighting. Solar lights do not require wiring, simple installation, installation is complete and ready to use, easy and fast to replace.
Program requirements
1. The size of the lamps is as small as possible. High brightness, adjustable brightness.
2. Good waterproof performance, adapt to complex weather.
3. Can be used normally in the winter temperature angle, summer temperature higher environment.
4. Easy maintenance.
Solution
The farm owner contacted sresky’s local partner in the US through a friend’s recommendation. By communicating the needs of the farm owner, the partner recommended the split design model SWL40PRO solar floodlight.
The solar panel and the luminaire can be installed separately, and the partner suggested to install the solar panel on the eaves and the luminaire under the eaves. Solar panels installed on the eaves are more conducive to absorbing sunlight and charging the battery more efficiently. In addition, although the luminaire is IP65 level waterproof, the waterproof performance is better, but installing the luminaire under the eaves can better reduce the impact of complex weather environment on the luminaire.
The SWL40PRO solar floodlight uses LED beads, with higher luminous efficiency and longer service life. The brightness of the luminaire can reach 6000 lumens, with a three-step midnight mode and three optional light-up modes, which can meet different brightness requirements. In addition, the luminaire applies sresky’s self-developed TCS technology, which can be used normally in -20°~+60° environment. ALS technology can keep the lighting time of the luminaire even in extreme bad weather.
