Billboards along highways are an important part of outdoor advertising media, especially these large billboards erected near the main line interchanges and toll stations. There is a lot of traffic from all over the country, and passengers can see it from all directions. The advertising effect Very significant, it is a business card to show the strength of the enterprise, enhance the popularity of the product, and promote the image of the city. Because the scenery along the expressway is monotonous, repetitive, and few visual obstacles. The billboards are made of high-precision spray painting, which has a strong visual impact. The content is simple and eye-catching, and it is more likely to be unintentionally noticed by drivers and passengers, so as to achieve strong advertising effect.
Highway Billboard Operating Benefit and Risk
Most of the large outdoor billboards use T-shaped steel pipe column structure, which is shaped like an anti-aircraft gun, so people in the industry abbreviate it as “aircraft gun”. High-quality highway billboards are an important business position for outdoor advertising media companies, and they usually obtain operating rights through various methods such as self-investment, lease, and bidding. Because highway billboards have a huge communication effect, it is quite expensive to rent related billboards for publication. Of course, it is accompanied by huge profit margins for advertising companies.
The establishment of billboards along the highway involves multiple departments such as land and resources, planning, urban management, public security, industry and commerce, highway management, etc. authorities. The approval procedures are particularly complicated, so the investment cost is quite large; at the same time, most of these single columns are temporary buildings. The legal use cycle is short, and it may be dismantled at any time, so the risk is great. If relevant advertising companies fail to find advertisers in time, they will put a heavy burden on operating costs.
Urgent Need to Solve Power Restrictions and Electricity Bills
Because most of the highway billboards are installed in a relatively remote geographic environment, and the power conditions are limited, the billboards “cannot be illuminated at night”, and it is difficult to achieve satisfactory advertising effects. If the cost of pulling electricity from a long distance is high, the business unit must spend a lot of time and energy to go through the approval of electricity use, and in the process of laying pipelines, weak current wells, high-voltage cables, etc., the land occupation approval procedures are involved, the construction period is long, and the cost is high. . At the same time, the highway management department has strict regulations on the safe use of electricity for billboards, and it is not allowed to connect electricity from street lights and power distribution rooms nearby.
Even for billboards that can get access to main electricity, advertising company operators must pay a large amount of so-called electricity management fees to related power supply units in addition to monthly electricity charges that are several times more expensive than commercial and industrial electricity prices. Another headache for advertising companies is that cables are often stolen or electricity is stolen from nearby construction sites and individuals, while bare cable connectors are randomly discarded in the wild, which can easily lead to electric shock accidents.
Therefore, it is an urgent need of advertising companies to solve the lighting power consumption of the billboards along the expressway, save electricity expenses and power safety.
Unreliable power supply method:
- Long-distance power supply: Try to pull power from a short distance from the billboard, set up a simple cable rack, 1 km away, to 10 kilometers away, regardless of cost, not too old.
- Diesel generators to generate electricity: Install diesel generators at or near the bottom of the billboard and hire a person to be responsible for generating electricity at night.
Solar Energy Generation
The use of solar power generation, that is, distributed photovoltaic off-grid power generation in technical terms, can solve the practical difficulty of highway billboards that cannot be turned on at night due to limited power consumption. Its working principle is: install solar panels (photovoltaic modules) above the billboards, after passing through the combiner box, connect with solar controllers and battery packs to form a set of photovoltaic off-grid power generation system, which is independent in the absence of a power grid run. As long as there is solar radiation, the photovoltaic module can generate electricity. The solar direct current is stored in the battery through the photovoltaic controller, and the floodlight is powered regularly at night to realize the “light up” of the billboard.
Highway billboards lighting use solar power, which has the following advantages:
- There is no remote power transmission problem, and there is no need to pay electricity fees and power management fees;
- Simple construction, no need to lay special cables and pipelines, installation can be completed and put into use within 2-3 days, low construction cost;
- DC low-voltage safety power supply system, no need to worry about human body or livestock electric shock accidents caused by various accidents;
- Solar power generation has no mechanical transmission parts, no noise, and stable performance.
Highway billboards use solar power to generate effective solutions when there is no electricity supply or high cost of electricity. Secondly, it is to save electricity expenses and reduce operating costs. At present, it usually takes three years for the investment in solar billboard lights to start recovering costs, and the price of solar billboard lights is getting lower and lower. Using solar power to illuminate highway billboards has become the choice of most advertising companies.
