1 Is Solar Energy Worth Buying?
Recently, I saw many netizens complaining that solar lights are not practical. I don’t know if you have noticed that the street lights on the street have been replaced by solar street lights one after another. If you get stuck, wait for these problems, you may even think that the name of solar lamps does not match the reality, and the discount will be greatly reduced! As a practitioner in the solar lighting industry, I was really frightened. I can’t kill everyone with one shot! There are no special regulations for this industry at present, which will lead to uneven quality of solar products on the market, both good and bad! The phenomenon of bad money driving out good money is common, but as long as we keep our eyes open, we can still identify good or bad products. Today, let’s talk about whether this solar lamp is worth buying.
Determine the demand, that is, the installation location, like installing street lights on the side of a rural road, then consider a variety of factors, and the first choice is solar street lights, because it can be installed according to local conditions and needs. For garden lights, it is also recommended to choose solar lights. It can also be installed as needed without pulling wires. The second two types do not require electricity costs, saving daily expenses, and the installation is simple and does not require pull wires. Save installation costs. Third, the safety factor is high. If the wire is pulled, if the operation is improper, it is likely to cause serious accidents such as electric leakage and fire.
Solar garden lights use sunlight as energy and solar radiation as energy. During the day, solar panels are used to charge the battery, and at night the battery supplies power to the garden light. There is no need for complicated and expensive pipeline laying, and the layout of the lamps can be adjusted arbitrarily. It is safe, energy-saving and convenient. Pollution, charging and on/off process adopts intelligent control, light-controlled automatic switch, no manual operation, stable and reliable work, saving electricity costs, and maintenance-free.
Are solar lights worth buying?
First determine where you are going to mount the solar lights. Some netizens bought a few solar lights and installed them as night lights at the door of their house, and many netizens commented that it would be better to install a light connected to the mains, and then settle accounts. How much is the electricity bill for a year, the cost of buying a solar lamp is so high, how many years will it take to pay the electricity bill to replace it, and so on. Indeed, there is nothing wrong with saying this. If it is really installed on the wall of the home, the cost of solar lamps and electric lamps is very different, but people often overlook a problem, it is electric lamps, you need to connect wires, connect a line from the power grid at home, This line is also costly, and if it is not properly operated, it may cause electric leakage, injury or fire hazard. The picture shows the solar ceiling lamp installed by my client in the backyard of the home. The whole lamp costs less than 100 yuan. It is bright at night, and it is not a problem to use it outdoors for waterproof and frost resistance. If he wants to install an electric ceiling lamp, at least the purchase cost is more than 30 for a better one, and he has to do the wiring himself. If he can’t install it himself, he has to hire an electrician to install it. The electrician installation also needs to charge 20 yuan and 50 yuan. Besides, for outdoor installation, the wires should also be waterproofed. After installation, electricity is still needed, and the electricity bill is also money. If you calculate it in sevens and eighties, it actually costs the same amount of money!
Let’s talk about whether solar lights are a scam
Some netizens suggested that the production of solar panels is fundamentally damaging to the environment, and solar energy is fundamentally a fraud of the century, etc. I really feel very ridiculous in my heart. A new thing will be encircled and hostile by traditional forces during its development, because they are vested interests. If you want to develop, you will definitely harm their interests. The dispute between Edison’s direct current and Tesla’s alternating current in the last century is an obvious example.
Now that we talk about direct current and alternating current
Here I want to complain again about those unscrupulous merchants who use exaggerated power to fool consumers. As we all know, the so-called power is calculated according to the conventional mains voltage 220V multiplied by the current. For example, alternating current AC 20W=voltage 220V*current 0.09A, this is the formula for calculating power, what does it mean? It means that if the power of your lamp is 20W when the voltage is 220V, then at least the current it needs is 0.09 amps. What about DC? Generally, the battery starting system voltage of solar lamps is 3.2V, 12V, etc. Here we take 3.2V as an example, DC20W=voltage 3.2V*current 6.25A, that is to say, a solar lamp with an actual power of 20W and a system battery of 3.2V, The starting current must reach 6.25A. Under such a large current, the greater the load of the conductor passing through, the thicker the wire required. This is why the wires of solar lights are thicker than the wires of general home improvement.
2 Summary
Whether solar lamps are worth buying depends on your installation environment. If you are in the wilderness without grid connection, solar lamps are your first choice. If it is used for home decoration, the requirements are not high, and it is more cost-effective to connect to the mains, then choose the mains lamps. However, with the continuous advancement of solar technology and the continuous decline of costs, it is believed that solar lighting will enter and replace the traditional civilian market within a short time!
