Durable solar street lights rely on sunlight for power and a stable base. Choosing a site for solar rural road light isn’t as simple as picking any empty space. You have to think about three important factors: sunlight, geology, and the environment, each of which has its own needs.
The first thing we’ll talk about today is sunlight.
The solar rural road light gets its power from the photovoltaic panel. The amount of sunlight directly affects how well batteries charge and how long they last on cloudy or rainy days. The main requirements are: no obstacles to sunlight, enough sunlight, and enough time.
First, think about how long the sun will be out. For photovoltaic panels to work, they need at least four hours of good sunlight each day. If this time isn’t long enough, even with a big battery, problems like “incomplete charging” and “less than 3 hours of light on cloudy or rainy days” will happen. A customer from the country used to insist on putting streetlights under the eaves, saying it would keep the rain off. But less than two months after they were installed, they complained, which meant they had to move them and pay for more labor and materials.
Second, you should stay away from things that get in the way. This includes not only big trees, tall buildings, and utility poles that are already there, but also things that will happen in the future. For example, saplings that are nearby may block sunlight after they grow into big trees in 3–5 years. Village entrance archways and bulletin boards may also cast shadows at different times. Also, there should be at least 1.5 meters of clear space above and around the photovoltaic panels to keep streetlights and tree branches from blocking them, which could affect how much power they make.
A good tip is to watch the area for 2 to 3 days in a row at noon and write down how the shadows change. This will make sure that there are no obstructions during the times when the sun is at its strongest. This is a lot more reliable than just putting up poles.
Site Environment
1. Geology and Load-Bearing Capacity: The site for the solar energy street light should be on solid ground that can hold a lot of weight. It should not be in an area with soft mud, underground cavities, or places that are likely to flood. For big things like high-mast lights, the soil’s ability to hold weight must be carefully checked. If it isn’t strong enough, a concrete foundation should be poured to keep it from falling over.
2. Drainage and Topography: Give flat areas the most importance. If you choose a site on a slope, you need to protect the slope or change the angle of the installation. Make sure that drainage is not blocked so that water does not stay in one place for too long and corrode parts of the equipment.
3. Nearby Amenities: For places along the road, make sure they are close to the edges of both motor vehicle and non-motor vehicle lanes, and stay a safe distance from pedestrian walkways. Avoid core greenbelt areas and fire lanes for industrial parks and residential areas to make sure that emergency response and daily traffic can get through without any problems.
Also, stay at least 3 meters away from high-voltage power lines and at least 1 meter away from underground pipelines like gas pipelines and fiber optic cables. To avoid damage during construction, look at underground pipeline distribution maps ahead of time. To keep the public safe, stay away from places that could catch fire or explode, like gas stations and warehouses full of dangerous chemicals. Also, don’t install anything in dangerous places like rivers and reservoirs. Site selection must comply with local urban planning, traffic management, and power department regulations, obtaining necessary approvals to ensure the installation location does not occupy public land or illegally affect the urban landscape.
