The document discusses Samsung SDI's residential energy storage system (RES) and how it helps maximize self-consumption of solar energy in homes. As renewable energy adoption increased, feed-in tariff policies were introduced but later decreased, making it more economical for homes to self-consume rather than sell excess solar energy to the grid. Samsung SDI's RES stores surplus solar energy generated during the day for use when energy consumption is higher in mornings and evenings. The RES solution has evolved over the years along with customer needs and market conditions.

3. Samsung SDI Energy Storage System | THE ADOPTION OF RENEWABLE ENERGY
As a means of reducing pollution,
the adoption of renewable energy
has rapidly increased.

have begun to install solar panels
to start utilizing“clean”energy.

5. Samsung SDI Energy Storage System | ESS FOR RESIDENCE | FEED-IN-TARIFF
To stimulate the use of renewable energy,
governments began to implement
a policy called Feed-in-Tariff (FiT).
$A feed-in-tariff (FiT) is an energy supply pol-
icy that promotes the rapid deployment of
renewable energy resources. A FiT offers a
guarantee of payments to renewable energy
developers for the electricity they produce.

6. However, as the price of electricity increased,
FiT began to decrease.This made it more eco-
nomical to actually“use”the solar-generated
electricity than selling it back to the grid.

7. This concept of“self-consumption”is
what brought our product to life. Our first
step was to find a way to maximize the use of
solar energy.This required us to investigate
the energy consumption patterns of customers.
Energy consumption in everyday homes
had a unified pattern, concentrated con-
sumption during the morning and night.
However, solar energy generation reaches
its peak during mid-day. This incongru-
ity raised the need to store surplus energy
generated during the day to consume dur-
ing the night or morning.
