A. You can directly produce electricity through solar power generation, and by consuming the electricity produced, you can reduce energy costs.
Additionally, the electricity produced through the solar power generation business can be sold by signing a Power Purchase Agreement, allowing for stable revenue generation.
Not only that, solar power generation can maintain stable performance over a long period of 30 years, and as an eco-friendly energy for the future, it enables sustainable development.

A. The procedure for constructing a solar power plant is as follows:
01. Site Selection for the Project - Verify Suitable Areas for Power Generation (Check Land and Building Sections)
02. Apply for Power Generation Business Permit - Submit to the Relevant Local Government Authority
03. Apply for Development Permit - Submit to the Relevant City or County Office
04. Business Registration - Apply at the Local Tax Office (City or County Level)
05. Electricity Supply Contract Application - Site Inspection, Point of Entry Decision (Confirmation before Generation Permit), Payment of Connection Construction Costs
06. Construction Plan Notification - Verification with the Relevant Local Government (Provincial Office, City/District Office), Selection of Electrical Supervisor (Design Supervision Contract)
07. Installation Works - Civil Works, Electrical Works (Decision on Modules, Inverters), Structural Works
08. Pre-use Inspection - Electrical Safety Inspection
09. Sales Contract - Electricity Supply Contract (KEPCO/KPX), REC Purchase Agreement (Mandatory Purchase)
10. Commercial Operation Start-up Notification - Report to Provincial/City/District Office
11. Installation Verification - Application for Verification of RPS (Renewable Portfolio Standard) Eligible Facilities, Confirmation by the Energy Foundation
12. REC Issuance/Trading - Renewable Energy Center (REC Issuance), Korea Power Exchange (REC Trading)

A. You should first check the feasibility and then make a plan.
01. It is advised to acquire knowledge related to solar power generation and, if you know someone who has already installed it, listen to their experiences.
02. Determine whether the purpose is to reduce electricity bills or to generate income by selling the electricity produced.
03. Plan for financing. (government subsidies, local government subsidies, and potential loan amounts, etc.)

A. When selling electricity produced by solar power, the typical approach is to install the maximum capacity possible within the given installation area. In this case, the pure installation cost ranges from around 1.1M to 1.4M KRW per kW.
Prices can become more expensive or cheaper, and this is because there can be large price differences depending on the equipment such as modules or inverters.
In addition, additional costs may occur depending on whether you install support frames or high voltage equipment.

A. RPS stands for Renewable Portfolio Standard, which is a regulation that mandates renewable energy quota obligations. It requires power generating companies to supply a certain percentage or proportion of their total electricity generation from renewable energy sources.
Korea Electric Power Corporation's 6 power generation subsidiaries and 7 private power generation companies are considered power producers. In order to meet renewable energy production quotas, these producers procure renewables by entering into long-term agreements with renewable energy companies to purchase RECs (Renewable Energy Certificates). RECs are issued by the Korea Energy Agency to renewable energy generators and the price of RECs is determined by market supply and demand dynamics.
SMP stands for System Marginal Price, which is the unit price of electricity purchased by Korea Electric Power Corporation (KEPCO) from various power generation companies. The sum of REC (Renewable Energy Certificate) and SMP (System Marginal Price) constitutes the revenue from electricity sales.

A. Check the building's shape, orientation, angle, and shadow.
- When installing solar panels, it is important to consider the building's shape, orientation (south-facing is optimal), and angle (within 30 degrees is optimal). Specifically, check if there will be any shading on the panels.
It's best to check for shading during the winter sunset when shadows are longest. Even if shadows cover only part of the solar modules, the power output can decrease significantly.
Check solar panel installation products.
-Be careful in selecting solar modules that can last over 20 years and inverters, which, if chosen incorrectly, might need to be replaced more frequently.
Check temperature and ventilation.
- Solar cells generate less power as the temperature increases, so it is ideal to have a path for the wind to pass through.

A. The modules of currently available standard products have an expected lifespan of 25 to 30 years. The commonly used solar cells are made of crystalline silicon, which is similar to stone and thus hardly ages.
However, the expected lifespan is determined by the durability of the resin, glass, and metal parts that protect the solar cells and electrical circuits. As for inverters, you can think of them as being similar to general household appliances, unlike solar cells.
Depending on which product and how a product is used, it may malfunction, so please make sure to check which product you are using for the inverter, just like with the modules, and what the warranty period is.

A. One of the advantages of solar power systems is that they do not require special cleaning or maintenance. Typically, they are designed so that things like dust are washed away by rain and wind, but it's good to clean off anything that doesn't wash away well.
For instance, in cases where bird droppings, wet leaves, and other debris do not fall off easily, or near roads with heavy traffic. You can clean them by spraying water, but be careful not to do it too frequently as it may cause water stains.
The best approach is to hire a professional cleaning company. It's advisable to have them check for any issues every 5 to 10 years.

A. Modules sold domestically are generally designed to withstand typhoons, hail, lightning and other extreme weather conditions. With proper installation and mounting structures, they can be as sturdy as buildings.
However, if too much snow accumulates on the modules, power generation may be reduced, so it is best to install them at an angle allowing the snow to slide off. In summer heat waves, the modules themselves won't be damaged but output may decrease.
There are also products that are resistant to high temperatures available, so please take those into consideration. And it is best to install them such that ventilation can occur properly.
