FAQs

The establishment of a solar power system requires administrative application to Taipower, the Energy Bureau of the Ministry of Economic Affairs, and the construction and management office of the county and city government. The system installation project will take one to three months depending on the scale of the site, and it will take about three to six months from signing the contract to the operation of the system; the follow-up administrative operations will go back and forth, and the bulk sale will officially start in about three months.

Soleibo Optoelectronics provides a one-stop service, all construction and running processes will be handled by us. You only need to prepare the required documents, and we will assist you with the relevant procedures for applying to the government and Taipower. The construction period will vary depending on the scale of the site and the construction method. Generally, the construction time for residential houses is about 5-10 days. Larger agricultural, fishery and animal husbandry facilities, factories, etc. can be completed in about 20-60 days.

According to statistics, the average household in Taiwan consumes about 303 kWh per month and 9.9 kWh per day.
The annual average sunshine in Yunlin reaches 1,250 hours and about 3.4 hours of sunshine per day.
If a 5kW solar system is installed, about 17 kilowatt-hours of electricity can be generated every day. Compared with electricity consumption, solar energy systems generate twice as fast electricity every day, which can not only increase the proportion of renewable energy but also spread the load on the grid.

Excluding the unusable space, the area required to install a 1KW solar photovoltaic system is about 2 pings. Therefore, if the roof space is 10 pings, a 5KW capacity system can be installed.

W=watt = Watt (Te), is the unit of power
1kW = 1,000W = one kilowatt = 瓩 (pronounced "kilowatt")
1 kWh = 1kWh = the amount of electricity consumed by an electrical appliance with a power of 1kW for "continuous use for one hour"
In other words, if you use a 1kW hair dryer to blow continuously for 1 hour, it will consume 1 kWh of electricity.
From the perspective of power generation, if you have a 1kW solar photovoltaic system, you can generate 1 kilowatt-hour of electricity under 1 hour of "effective sunlight".
So if you are in a cloud forest where the average daily sunshine hours are about 3.5 hours, and a 10kW solar photovoltaic system is installed on the roof, then under ideal conditions, an average of about 35 kilowatt-hours of electricity can be generated per day.

Both solar water heaters and photovoltaic systems are environmentally friendly renewable energy equipment. Solar water heaters are "light-to-heat", which uses heat collectors to absorb the "heat energy" of sunlight to heat water; while solar photovoltaic systems are "light-to-heat". Electricity conversion uses solar modules to collect the sun’s “light energy” and convert it into “electricity”.
If you already have a solar water heater, we will plan and design the most effective way to use the space, and perfectly combine the solar photovoltaic system and the water heater to create a greener life for you!

   2. Set up the site as a legal construction site
   3. The structure is sufficient to support solar photovoltaic panels
   4. Sufficient regional feeder capacity
   5. Legal construction, and there is a copy of the house and land ownership certificate or a transcript of the land register

1. Solar energy is renewable energy, so don’t worry about energy exhaustion.
2. Reduce carbon dioxide emissions and improve air quality.
3. Increase the proportion of independent energy sources and reduce the risk of energy dependence on imports.
4. Distributed power system, the electricity generated can be effectively used nearby.

1. With shading and heat insulation effects, the temperature can be reduced by 3-5 degrees, saving air-conditioning costs.
2. Waterproof and shading can protect and extend the life of a building roof.
3. Effectively activate and utilize idle space.
4. High return on investment, 20 years of long-term stable profitability.

● Option One-Roof Rental:
The homeowner can get a complete set of a solar photovoltaic roof without any investment, which can protect you from wind and rain, protect the roof, and help cool the house by 3-5 degrees.
The amount of electricity sold will be paid back to the homeowner in proportion to earn a stable rental income.
The lease contract is notarized by a third-party notary unit to protect the rights and interests of the homeowner for 20 years.

● Option Two-Self-built system:
The homeowner's self-financing committee will build the solar photovoltaic system by Minghui Energy.
The homeowner can earn full income from the sale of electricity.

-Company organization: Regardless of the level of sales, it should go through business registration and issue uniform invoices for business tax payment.
-Natural persons: Those who have an average monthly sales of less than 80,000 yuan are exempt from business registration and exemption from business tax. Taipower Company shall fill in the declaration form at the time of payment, and the natural person shall declare the comprehensive income tax based on the profit income.

Bulk purchase rate (yuan) x annual sunshine hours (hour) x set capacity (KW)
Example: 10KWp on the roof of Yunlin Residence
   -Annual income: 6.1216 x 1,250 x 10 = 76,520 yuan
   -Income in 20 years: 76,520 x 20 = 1,530,400 yuan
* The results of the trial calculation are for reference only, and the actual income and power generation will vary according to the site conditions and setting methods of each case.

According to the "Regulations on the Development of Renewable Energy", unless the local feeders are insufficient or have considerable obstacles, and the central competent authority determines that they cannot be connected in parallel, Taipower, as an electricity business operating the power grid, is obligated when all power generation installation fees meet the relevant regulations. They are connected in parallel and signed, and electricity must be purchased following the law after signing the contract.

The owner of the power to sell electricity can transfer freely. If the house or building is resold in the future, it can be undertaken by a third party (new homeowner).
If you are renting a roof, the lease contract specifically states that the sale and purchase will not break the lease terms, so remember to explain to the new homeowner that you must undertake the roof lease contract before selling the house.

Factors such as shade, dust on solar panels, hours of sunshine, and intensity of sunshine may affect power generation efficiency.

The solar photovoltaic system is equipped with a multi-purpose inclined design, which has a self-cleaning effect and can be washed by rain to remove dirt, black dung, leaves, or spider webs on the solar panel.
Since the outer layer of the solar panel is made of glass, only clean water (high-pressure water jet), long rod mop, and other tools can be used to clean the solar panel without the use of any chemicals.

The solar power module is guaranteed for 20 years, but it can be used permanently if there is no serious damage. Its efficiency can maintain 90% in 10 years and 80% in 25 years, so it can maintain more than 80% efficiency in 20 years.

The solar photovoltaic power generation system does not produce noise when it is running. Even if a solar panel of up to 20,000 watts is installed on the roof, the electromagnetic waves it generates are about equivalent to a general household appliance (such as a home computer), which is much lower than that of the Environmental Protection Agency. The recommended value of the environment is in full compliance with human safety regulations, and there is no doubt that electromagnetic waves will harm the human body in use.

The solar photovoltaic system is completely pollution-free when in use. However, during the manufacturing process of solar panels, industrial wastewater and waste gas pollution may be generated, and factories are required to conduct pollution prevention and control (wastewater and waste gas treatment) according to law. The solar panel manufacturing process is similar to the semiconductor manufacturing process, but without the front-end cutting-edge process of the mask, and the previous cutting-edge process is also the main area where waste gas and wastewater produce toxic and carcinogenic species. In other words, its pollution is more than that of ordinary semiconductor factories. Less. Moreover, compared to traditional coal-fired power generation (thermal power generation), even if the solar photovoltaic system is added to the pollution during manufacturing, there is still more than 90% less air pollution than coal-fired power generation.

The installation of solar panels must choose the appropriate azimuth and inclination angle.
Since Taiwan is located in the northern hemisphere, in terms of relative position, most of the sunlight is slanted from the south, so if you need to get more power generation, the direction of the solar panels must be toward the south.

After the azimuth is determined, it is the part of the inclination angle. If you want to obtain higher sunlight intensity, you must let the sunshine directly on the solar panel. Therefore, the solar panel needs to be at the optimal inclination angle. The higher the latitude, the higher the latitude, The corresponding inclination angle is also larger. The current installation angle in Taiwan will be set at the local latitude or the angle of the roof surface of the building to ensure the best power generation.

Turns out to be silicon (Si)
At present, the main material used in solar cells is silicon (Si), but silicon itself has a reflectivity of more than 30% for visible light, which will affect the absorption effect of light energy. Therefore, to increase the absorption rate, another layer of anti-reflection In the process of absorbing light energy, the panel reduces the loss due to reflection, but because the anti-reflection layer cannot completely block the overflow of blue light, the solar panel becomes dark blue.

Those who meet one of the following conditions may be exempted from applying for miscellaneous licenses by the provisions of the Construction Law:
1. Installed on the roof or terrace of a building, the height of which is less than three meters from the roof or terrace.
2. Set on the roof protrusion, the height of which shall be less than 1.5 meters from the surface of the roof protrusion.
3. It is installed on the ground in a severely subsided area designated by the central competent authority, and its height is less than four meters from the ground.
4. The height of the ground set up on the salt industry land or changed from the land to special-purpose business land shall be less than 4 meters from the ground.
5. Set on the ground other than the preceding two paragraphs, the height of which shall be less than three meters from the ground.
(Remarks: The horizontal projection area of ​​the operation and maintenance tunnels or passage facilities that are higher than the installation surface shall not exceed 30% of the overall horizontal projection area of ​​the photovoltaic power generation equipment. The photovoltaic power generation equipment is installed on the roof, terrace, or roof protrusion, The equipment shall not exceed the scope of the setting area).

The "development of other energy sources" mentioned in Article 11, Paragraph 1, Subparagraph 10 of the "Tap Water Law" refers to the construction or expansion of thermal power plants and specialized cogeneration power plants. Therefore, the installation of solar photovoltaic power generation equipment does not belong to the "development of other energy sources" referred to in Article 11, Paragraph 1, Subparagraph 10 of the "Water Supply Law".

The "development of other energy sources" mentioned in Article 5, Paragraph 2, Subparagraph 3 of the "Drinking Water Management Regulations" refers to the construction or expansion of thermal power plants and specialized cogeneration power plants. Therefore, the installation of solar photovoltaic power generation equipment does not belong to the "development of other energy sources" referred to in Article 5, paragraph 2, paragraph 3 of the "Drinking Water Management Regulations".

Solar photovoltaic power generation facilities must be installed on the roof of the farmhouse. In addition, the photovoltaic power generation facilities are not ancillary facilities of farm buildings and agricultural facilities, so they are not allowed to be installed on agricultural land where farm buildings are constructed.

The application is filed in accordance with the "Key Points for Review of Business Plans for the Use of Non-Urban Land Application Change to Solar Photovoltaic Power Generation Facilities".

1. The Ministry of Economic Affairs has announced that areas with severe stratum subsidence or remote and outlying islands designated by the central competent authority will be exempted from paying agricultural and pastoral land rewards.
※ The rebate funds for land use types other than agricultural and pastoral land are paid in accordance with the regulations and recognized by the authorities of each land use.

2. According to the calculation basis of "Agricultural Land Change Rebate Payment and Distribution and Utilization Method":
