Photovoltaic System [standalone]

- A stand-alone system is the system for supplying electric power only to the solar power system for use fee can not connect to the commercial system, islands, and the like separate place self-generation is desired.
- Stand-alone system will be comprised of solar modules, inverters, batteries, charge regulators, etc.
- The principle of operation is the configuration so that the part where you need to take advantage of the power generated during the day and had happen and save the power left in the battery can be used at night.

- The current ESS Technology is as a demonstration phase and bogeuphwa stage, that the barriers of technology businesses.

 

 

 

Solar Power System - On-Grid]


- Grid-tie systems are developed in conjunction with the solar power system and a commercial song, says that you can faucet system.
- Grid-tie system will be composed of photovoltaic modules, grid-connected inverter, power transmission equipment.
- The working principle is sent to the connection to the electric power generated during the day on a commercial system power line, and a faucet that can generate revenue to provide efficient power exchange and trading the surplus electric power business.
(This project can take advantage of the maximum benefits when linking the FIT and RPS business.)

 

 

 

Glossary: FIT System and RPS system


  • FIT FIT system is short of power generation systems. By Price (Future Creation Science Minister announced price) and electricity trading system that supports the balance of the price (the power produced by the solar trade price). Until last year, this system has not been implemented, the information that is being revived again.
  • The RPS system is a system that imposes ever supply a certain amount or more of the total power generation businesses above a certain size to develop renewable energy power. The person responsible for the development of business here is to supply Korea Hydro & Nuclear Power, East Power, Central advances inde 13 power companies, you can substitute for their solar power supply through another provider. The certificate will make a deal with the supply of REC.

 

 

 

Glossary: REC and SMP


- If you sell without the use of solar power to produce electricity directly installed by you. A solar power production can be sold in two places.

  1. SMP: the price of electricity sold to Korea Power System Marginal Price: You can say (SMP system Marginal Price). That is the purchase price to be paid to KEPCO private power providers (those who develop PV).
  2. REC: operators can develop him set mandatory production of renewable energy from the government. They will be sold as a supply certificate called REC.
※ If that is the deal with solar power is the deal, including the REC + SMP.

 Generation system over water
  • Solar power system, such as the above data when building the government's support policy development is greater than the difference between the roof and the general premises of the factory, water development is a big advantage.
  • Rooftop power generation system is lightweight, and easy installation is suitable for a solar cell, flexible CIGS thin film solar cell that we have the benefit of the maximum.
  • This is the best rooftop solar PV. You can also take advantage of the roof is highly recommended to promote solar power.

 

 

 

Rooftop solar power project (roof and rooftop leasing business mecca of development projects)


What is the difference between developments in the aforementioned rooftop solar project is the largest development projects. Rooftop power generation business is done is composed of the following systems:
  • Rooftop solar power is by using non-haejum rent a factory roof, the roof can be rental business, and by ensuring the long-term management of the roof, the roof is a stable management. In addition, the solar power difference is larger than a typical forest profitability like 5-6 years Payback is a business that can be enough.
  • The position corresponding to 2015 carbon credits from enhanced policy enforcement are gachiseong You also might try a lot of challenges in rooftop solar power.

 

 

 

System Configuration Considerations: advantages and disadvantages of drive configuration

In general, the most important part of the PV inverter well chosen during installation, to the configuration. That is how to configure the inverter with regard to, you can split into separate. I hope to fit the individual's use of the inverter system implementation considerations.

1. Seutiring inverters (string inverters)
  • The module of one of the large capacity of the inverter as shown in the figure above is connected in series.
  • Benefits: The benefits that can save the initial investment in a more economical compared to when you have installed a micro-inverter.
  • Disadvantages: The output of the module is can have implications on the overall system output can also generate the reduction of the output. If solar modules can reduce 54% of the total system output when you encounter a shadow covering 9%. The cooling fan should be installed so that the problems with noise and occupies more space resulting from the pan.
  • String inverters are suitable for installation in environments that are shadows in the solar system.

 

 

 

2. Micro Inverters (micro inverters)
  • The way to connect the inverter to the small size of one or two modules as shown in the figure above. For instance, if you are installing a system of 10KW inverter 250W to 250W module is to install a 40 or 500W inverter 20.
  • Advantages: The comments in the string, and the overall system output inverter is increased 5-25%, less likely to damage by heat, one or two modules on the advantage that it can be adjusted so michichi affect the overall output when a problem.
  • Cons: string about 30% higher than the initial investment cost disadvantage when installing the inverter.
  • If you are considering installing solar framework where the shadow is frequently occurs, or if the thermal part, the efficient development, it is possible to install than a micro inverter string inverters.
