Solar + BESS

Maximize solar self-consumption, reduce grid dependency

Problem

Solar PV systems generate excess energy during midday that is exported to the grid at low value, while factories buy expensive grid power during peak hours. Without storage, solar self-consumption rates remain low.

Site Conditions

Existing rooftop or ground-mount PV system
High daytime solar generation exceeding on-site load
Low feed-in tariff making export uneconomical
High peak electricity tariffs

PSN Solution

PSN Energy BESS stores excess solar energy during generation peaks and discharges during high-tariff periods. The EMS intelligently manages charge/discharge cycles to maximize self-consumption and minimize grid import.

Operating Logic

Solar Generation Peak

Excess PV charges the BESS instead of exporting to grid

Evening Peak Demand

BESS discharges stored solar energy to cover factory load

Grid Available

System optimizes between self-consumption and grid import

Grid Failure

BESS provides backup power using stored solar energy

Key Benefits

Solar self-consumption rate increased to 80%+

Reduced grid electricity import

Lower electricity bills through time-of-use optimization

Backup power from stored solar energy
