FAQS
Q :
What are the key factors in the selection of PV modules?
A :
Efficiency and attenuation rate: High-efficiency modules (such as TOPCon, HJT) can increase power generation, and low attenuation rate (first year <1%) guarantees long-term benefits. Environmental adaptability: Need to match the climate of the project site (such as high temperature, dust, salt spray). Cost and life: Balance the initial investment with the cost-effectiveness within the 25-year life cycle.
Q :
What are the key parameters for energy storage system design?
A :
Capacity and power ratio: Determined according to the fluctuation of photovoltaic output and load demand (such as 2 hours of energy storage time). Cycle life: Lithium batteries must meet ≥6000 cycles (80% residual capacity). Safety: Thermal management system and fire protection configuration must comply with national standards (such as GB/T 36276).
Q :
How to reduce the levelized cost of electricity (LCOE) of the project?
A :
Scaled procurement: Reduce the unit price of equipment through centralized procurement. Improve utilization: Optimize energy storage charging and discharging strategies and reduce the rate of abandoned light. Policy subsidies: Apply for local new energy subsidies or green electricity trading premiums.
Q :
What is the difference in income between surplus power grid-connected and self-generation and self-use modes?
A :
Surplus power grid-connected: The electricity price is based on the local desulfurized coal benchmark price (such as 0.3-0.4 yuan/kWh), and the income is stable but low. Self-generation and self-use: The electricity price is based on the industrial and commercial electricity price (0.6-1.2 yuan/kWh), and it needs to be tied to a stable electricity load (such as factories and parks).
Q :
What are the main difficulties in grid access approval?
A :
Capacity limitation: The grid carrying capacity in some areas is insufficient, and it is necessary to negotiate the expansion plan with the grid company in advance. Technical standards: It must meet the
Q :
What issues should be paid attention to in land compliance?
A :
Land use nature: Prioritize unused land or industrial land, avoid basic farmland and ecological protection areas. Land rent: It is necessary to sign a long-term agreement (20-30 years) with the local government to avoid the risk of price increases in the middle. Environmental impact assessment requirements: It is necessary to evaluate the impact of the project on vegetation, water and soil, and formulate a restoration plan.
Q :
How to deal with the fire risk of energy storage batteries?
A :
Preventive measures: Use lithium iron phosphate batteries (thermal stability is better than ternary lithium), configure BMS real-time monitoring. Emergency plan: Install a gas fire extinguishing system (such as heptafluoropropane) and set up a fireproof isolation cabin. Insurance coverage: Purchase property insurance and third-party liability insurance to transfer potential losses.
Q :
What is the core task of long-term operation and maintenance?
A :
Equipment monitoring: Real-time monitoring of component efficiency and battery health status through an intelligent platform. Regular maintenance: Clean photovoltaic panels every six months and test the internal resistance of the energy storage system every year. Fault response: Establish a 24-hour operation and maintenance team to ensure on-site processing within 2 hours.
