ESS for RESIDENCES

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.

- 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. $-cents / kWh 2010 20122011 2013 2014 Grid Parity Electricity Price FiT Self consumption Samsung SDI Energy Storage System | ESS FOR RESIDENCE | self-consumption Copyright © 2014 Samsung SDI.

- 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.
