1. Project Overview
Objective: To construct a 1MWp PV power generation system on the top of vegetable greenhouses, and to install an appropriately sized energy storage system. This project aims to achieve clean energy generation, local consumption, peak-valley arbitrage, enhance grid stability, reduce agricultural electricity costs, increase comprehensive agricultural income, and create a demonstration project for the integration of modern agriculture and new energy.
Location: [NingXia,China]
Scale:
PV installed capacity: 1 MWp (DC side)
Energy storage system capacity: determined based on electricity load, peak-valley electricity price difference and smooth output demand .
Covered greenhouse area: approximately estimated value, e.g., 10,000 square meters
Core model: “Agriculture and PV complementarity” + “Integrated PV and energy storage”.
