ABOUT
Why Solar + Storage is the new standard?
Energy challenges today demand more than traditional solar.
Combining solar PV + battery storage (BESS) ensures efficiency, savings, and energy independence.
Generate and store your own energy
Avoid peak-hour tariffs
Gain independence from the grid
Why PowerChina?
Store low-cost energy (solar or from the grid) and use it during peak demand. This strategy reduces maximum demand charges, which can account for up to 40% of a company’s electricity bill.
WHAT IT IS?
Reduce bills by up to 40% by avoiding maximum-demand charges.
BENEFIT
Stable consumption, fewer penalties, more profit.
OUTCOME
Avoid costly penalties and ensure a stable consumption profile—especially valuable under increasingly complex, time-dependent tariffs.
