If you want to add a lamp post to your yard, garden or patio a solar version of it has many benefits over a traditional one. Solar lamp posts don't require wiring which saves you lot of work of digging ditches for the wires. Solar lamp posts save you on electricity bills and require low maintenance. The only required maintenance is to occasionally wipe the solar panels to facilitate sunlight absorption. You don't even need to turn it on every night as the most of modern solar outdoor lighting systems have a light sensor which allows them to automatically turn on at night and off in the morning. Aimed at outdoor usage, solar lamp posts must certainly be waterproof. A standardized waterproof rating is devised to delineate how successfully an outdoor solar light will handle the rainy weathers. The standard is called Ingress Protection (IP) followed by 2 digits, for instance, IP65. The first digit shows the protection level against solid materials like dust, the second one shows how well the lamp post is protected against liquid ingress. The main drawback of solar lamp posts, and solar technology in
How Do Solar Lamp Posts Work?
Solar lamp posts resemble their traditional counterparts from a distance but they have some crucial differences. First, there are one or more solar panels integrated on the lamp's cap. It is important for the PV panels to be oriented towards the sun so it's recommended to install the lamp post away from the shades of trees or other objects. Second, solar lamp posts have built-in batteries that are charged during the day through the solar panels. When it gets dark the sensor turns on the light and it runs on the power stored in the batteries during the day. If the day was sunny and the batteries have large enough capacity (measured in mAh) the light can last all the night otherwise the light will go off sometime at night depending on the available battery charge.
