The cost of renovation is always one of the issues that consumers are most concerned about. There are many home improvement companies on the market, and the difference in quotations is often very large. Many consumers have encountered this kind of confusion: In the same home improvement market, a new house with an area of ​​120 square meters is also a company with a quote of 48,000 yuan, while another company next door quotes only 32,000 yuan. Almost the same renovation content, even a difference of 10,000 yuan in price. Why does the decoration offer have such a big difference?
In general, the cost of decorating and decorating should include: design fees, main materials, auxiliary materials, working hours, management fees and taxes. However, consumers need to be reminded that they should not simply choose home improvement companies based on prices. Because so far there is still the decoration company in the use of consumers do not know how to play "flowers" on the quote phenomenon.
So, what aspects should the audit of the decoration company's quotations be started with?
Pay attention to verifying the "addition" in the decoration offer
Although some home improvement companies offer very low prices in the initial period, they often have a lot of additions after signing a home improvement contract with consumers. Some designers even deliberately lost or missed items. If it was originally a good conversation with the designer, it was not stated in the contract and the consumer did not notice it. In this case, although the price was not high when the contract was signed, when the project was completed, there was a lot of content and expenses increased. The most common "additional content" includes: before signing a contract, the decoration company does not report the price of water, circuit modification, and not the light pipe, but in the final settlement, it has all the highest price; or in the water, circuit transformation construction. At the time, it was intended to extend the length of the water and circuit pipelines, causing consumers to suffer additional losses.

Led solar wall lights have the following advantages:
1. Definition of solar wall light
The led solar wall lihgt is a kind of lamp that utilizes solar energy to generate electricity, store energy, use electricity and lighting, and has a fully automatic control system. It is no different from the traditional wall lamp in appearance, and also includes basic structures such as lampshade, light bulb, base, etc., but in addition to these, it also includes important components such as solar cell components and automatic controllers.2. Working principle of led solar wall light
In addition to the components of traditional wall lights, solar led wall lights also have components that traditional wall lights do not have, such as solar panels, controllers, and batteries. Its specific working principle is as follows: during the day, when the sun shines on the solar cell, the solar panel will convert the thermal energy generated by the light radiation into electrical energy, and the battery will be charged and stored through the charge controller. When the night comes, the controller will control the discharge of the battery to meet the needs of night lighting.
3. Features of solar powered led wall light
1. The primary feature of the solar wall lamp is that it can be charged automatically. When the sun shines during the day, the solar wall lamp can use its own components to convert light energy into electricity and store the electricity, which is impossible for traditional wall lamps.
2. Solar wall lights are generally controlled by intelligent switches, and they are automatically turned on by light control. Usually it will automatically turn off during the day and automatically turn on at night.
3. Since the solar wall lamp is driven by solar energy, it does not need an external power supply or complicated wiring, and the work is very stable and reliable.
4. Ultra-long service life, the solar wall lamp uses semiconductor chips to emit light without filament. Under normal use, the lifespan can reach 50,000 hours, compared to 1,000 hours for incandescent lamps and 8,000 hours for energy-saving lamps. Solar wall lights can be said to be very long-lived.
5. We know that ordinary lamps and lanterns contain two elements, mercury and xenon. The used lamps and lanterns after use will cause great pollution to the environment. But the solar wall lamp is different. It does not contain the two elements of mercury and xenon, so the waste solar wall lamp will basically not cause environmental pollution.
6. Health. The light of the solar wall lamp does not contain ultraviolet rays and infrared rays, and this kind of light will not cause harm to the human eyes even if it is in contact for a long time.
7. Safety. The output power of the solar wall light is completely determined by the solar battery pack, while the output of the Tianyang solar battery pack depends on the temperature of the solar surface, that is, the intensity of the sun. The standard output of solar cells per square meter is about 120 W. Considering the panel area of the solar wall lamp, it can be said that its output voltage is very low, and it is an absolutely safe light.
