Why Solar Power and LED Lighting Makes a Perfect Combination.

With an increasing emphasis on sustainable energy, we are starting to focus a lot more on where our energy dollars are going and its implications in the future. However, so many aspects of energy consumption need to be addressed that the current focus on the big picture often prevents us from addressing our energy situation one step at a time. If we break down our energy consumption, we find that lighting is one of our biggest issues because of the amount of light we require daily and the inefficiency of our current lighting solutions. It’s time to realize that traditional light sources aren’t cutting it anymore and move forward to more efficient and sustainable long-term solutions. One such solution that has been gaining a significant amount of attention recently combines the sustainable benefits of solar power with the energy efficiency of LED lighting. So what makes solar power and LED lighting the perfect combination? Let’s dig a bit deeper into the technologies behind them to find out.

Advantages of solar street lights

Simple installation

The installation of solar LED street light is simple and convenient because no extra wiring is needed. It only requires a concrete base and a battery box (A split solar street light can be selected according to need, and an all-in-one solar street light is built in.). Installation does not require extensive labor, materials, and other costs.

Energy-saving and eco-friendly

Solar street lights convert sunlight into electricity without power consumption. No pollution and no radiation are in line with the current environmental protection concept. With LED sources, it can be said to be the icing on the cake.

Safety

Traditional LED street lights may have potential safety hazards due to construction quality, material aging, power supply confusion, and other reasons. While solar LED street lights do not use alternating current, there is no potential safety hazard, which brings convenience to electricians to maintain lamps.

Durable

Most solar panels on the market are stable for at least ten years due to mature manufacturing technology. They can generate electricity for thirty years or more.

High technical content and low maintenance cost

The solar street light is regulated by a solar charge controller, which can adjust the light intensity according to the natural brightness and people’s needs. In remote areas, the daily maintenance costs of traditional street lights are very high. The solar street lights only need regular inspections, and the maintenance cost is relatively low.

Short payback period

Solar LED street lights do not need to pay electricity bills, and in this era of high energy prices, the payback time is greatly shortened.

Disadvantages of solar street lights

Due to the shortage of traditional energy, the application of solar energy will be more extensive. Solar street lights have been applied on many occasions. However, there are also some restrictive factors in the application and promotion of solar street lights.

Large initial investment

One of the factors is the initial cost . The initial investment in solar street lights is large. According to the survey, the total cost of installing a solar street light is often three or four times or even more than that of a traditional LED street light.

The service life of the battery

Batteries have always been a bottleneck for solar application. Generally speaking, ordinary batteries cannot be fully charged for a long time, and their charging efficiency may drop to 50%, which will definitely affect the lighting conditions at night on continuous rainy days. Therefore, choosing a high-quality battery is crucial when installing solar street lights.

Batteries are easy to be stolen

Because they are not grid powered and it has a higher monetary value than regular street lights, the risk of theft is relatively high. This is why the battery often needs to be buried or placed high on the pole.

Low conversion efficiency

The conversion efficiency of solar panels is almost 15%~17%. In theory, the conversion efficiency of silicon solar panels can reach about 30%. So we think there is still space for improvement.

Snow or dust

Snow or dust, and moisture can accumulate on horizontal PV panels. This has an impact on the conversion of solar energy. The solar panel needs to be cleaned regularly in some places like Saudi Arabia.

Geography and Weather Conditions

Since solar energy comes from the sun, geography and weather conditions directly affect the lighting conditions of solar street lights. Continuous cloudy and rainy days will affect the lighting, so the illumination or brightness of the lights does not meet the national standards. To make matters worse, solar street lights cannot be lit sometimes, especially in winter.

Lead-acid battery contamination

Currently, many suppliers are configuring lead-acid batteries for buyers to reduce costs. They are mainly composed of lead, sulfuric acid, and some other metals and plastics. Waste battery acid contains a large amount of lead, and the random discharge will not only seriously pollute the soil and water flow. In addition, the recycling and processing of waste batteries in China are still in a relatively disordered state, so many waste lead-acid batteries are polluting our living space, even if gel batteries are used, pollution still exists.
