Solar energy is the light energy received by the earth from the sun. The principle of power generation is to let the sunlight directly irradiate the solar cell under the condition of light (including the light generated by sunlight and other luminous bodies), and use the solar cell to absorb the sunlight. , a power generation method that converts light energy into electrical energy output.
The electricity production is calculated based on the daily effective sunshine time, plus the system power generation capacity after the depreciation of shading and other factors. According to NASA weather data, the effective sunshine time of the Hong Kong Observatory is 3.56 hours per day, while some suppliers on the market use the Hong Kong International Airport for 4.02 hours, ignoring the impairment of shading and resistance and directly multiplying the power generation capacity. The calculated power generation is exaggerated, resulting in a very fast payback period, so there is a big gap between the expected and actual power generation and income.
We must refer to accurate weather data, coupled with system design and simulation, and cooperate with shading analysis, in order to calculate the actual power generation as close as possible.

In the process of solar panels absorbing solar power, only a very small amount of current is generated. The electromagnetic waves it generates are only equivalent to a general household appliance. The solar power generation system is installed on the roof farther away from the residents, so the radiation can be said to be negligible.
Generally speaking, the payback period will be set within 3-5 years. (shading analysis, structure and other factors need to be considered)
have the following provisions
• The height of the system and its support shall not exceed 1.5 meters from the roof to the floor
• The average load must not exceed 150 kg per square meter
• The system must not protrude more than 750mm from the exterior wall
• For systems installed in continuous coverage mode, the coverage area (only counting the covered area in the building) shall not exceed half of the covered area of the exempted building in the New Territories
• The height of the system and its support shall not exceed 1.5 meters from the roof to the floor
• The average load must not exceed 150 kg per square meter

• For systems installed in continuous coverage mode, the coverage area (only counting the covered area in the building) shall not exceed half of the covered area of the exempted building in the New Territories
The main accessory of the solar system is the inverter. The inverter converts the direct current output from the solar panel array to alternating current. Isolation transformers installed inside or outside the inverter help prevent DC power from being injected into the distribution system.
The life of the solar panel is about 20 to 30 years, and the life of the inverter is about 5 to 10 years.
The construction cost and power generation cost of a renewable energy system will vary according to the power generation capacity of the system. Generally speaking, the larger the power generation capacity of a renewable energy system, the cheaper its average construction cost per kilowatt, and the lower its average power generation cost. Setting different levels of on-grid tariffs can more effectively and fairly reflect the factors of power generation capacity and average power generation cost.
After considering the size of the renewable energy system most likely to be installed in Hong Kong's environment, we should have different levels of feed-in tariffs covering different systems,
The smallest class (10 kW or less) covers solar systems on the roofs of most village houses;
The second level (over 10kW but 200kW or below) covers solar systems on rooftops of general buildings (e.g. systems at the Airport Police Station and Wan Chai Government Buildings);
The third level (over 200 kW but 1 000 kW or below) covers relatively larger solar systems (such as the system at the Headquarters of the Electrical and Mechanical Services Department).

According to the "Business Registration Ordinance" (Chapter 310) and the "Inland Revenue Ordinance" (Chapter 112), individuals who participate in the feed-in tariff must apply for business registration and submit a profit tax return, through the sale of renewable energy to power companies. Profits tax is payable on the assessable profits.
However, in order to encourage individuals to consider installing renewable energy systems in their homes, the Environment Bureau will propose legislative amendments to exempt individuals from the above-mentioned requirements for participating in the feed-in tariff scheme for small-scale renewable energy systems in their homes.
