Solar construction process and benefits

Additional benefits through reduction of electric charges and effect of special rates on new renewable energy by installing solar in shopping malls and housing

Benefits of self-consumption solar energy

  • Saving of electric charges by consuming self-produced electricity

  • Discount of electric charges by New Renewable Energy discount system

    Ex) When installing 3kW 3kW x About 3.6 hours (Annual average generating hours) x 365 days = 3942kWh

  • Annually about 600,000won of cost-saving effect

    Annually about 370,000won +About 180,000won from discount for new renewable energy + Progressive tax avoidance effect

Discount of New Renewable Energy

Current Revised
10~20% discount of total electric charges according to the self-consumption ratio of new renewable energy (Excepting if self-consumption ratio is less than 20%) 50% discount of electric charges saved by self-consumption of new renewable energy (Self-consumption X Average unit price during the middle and maximum load time of previous year X 50%)

RPS (Renewable Portfolio Standard)

A system that imposes power producers (supplier) with generating units (excepting new renewable energy generating units) over a certain size (500MW) a duty to supply more than a certain percentage out of total energy production using new renewable energy

Renewable Energy Certificates (REC)
and System Marginal Price (SMP)

Solar generation quantity is sold to KEPCO or Korea Power Exchange through the payment of price (SMP), and sellers are granted REC according to the weighted value granted by Korea Energy Agency when they sell to power market. 1 REC is calculated as a unit of 1MW. Accordingly, {Monthly total output (kW)x Weighted value}/1000}=REC (Decimal point rounded off)
ex) In case solar generation unit is installed on top of a building (Monthly energy production 1000Kw, Weighted value 1.5)
1000 * 1.5 / 1000 = 1.5REC (1REC created, 0.5REC accumulated)

Sale of Electric Power

Effective installation using veranda railings

As a solar energy generating unit using railings of apartment or house, it aims to reduce the use of electrical power system of KEPCO.
