Why Does a Commercial PV Enquiry Need an Electricity Load Profile

Use time-based consumption data to discuss how PV generation may align with the building's demand. Annual energy totals do not show operating hours or non-working days. Record the meter boundary, time zone and data quality before comparing design options; any savings estimate needs the project's actual tariffs and assumptions.

Practical review checklist

· Define the boundary. Identify which buildings and loads are included in the meter data and which may change.

· Check the timeline. Record interval length, time zone, missing periods and whether daylight-saving handling is relevant.

· Describe operating patterns. Explain shifts, shutdowns, seasonal demand and planned equipment changes alongside the data.

· Compare stated scenarios. Ask the analyst to keep the same load data when comparing layouts, unless a change is explicitly explained.

When to request clarification

Keep conclusions conditional when data are estimated or the meter serves unrelated loads. Do not promise a self-consumption rate or payback from a monthly bill alone.

Questions buyers ask

Can an annual bill replace interval data? It gives context but cannot show when demand coincides with generation.

What makes a review record useful? It identifies the actual equipment, source evidence, responsible person and unresolved conditions so a later reviewer can follow the decision.

Information to send with an enquiry

Send available interval meter data, bill periods, operating schedules and planned changes, with sensitive account information removed where unnecessary.

This is a project discussion checklist, not an installation instruction or an approval. The selected manufacturers, project engineer and local authority must confirm the applicable requirements.

工商业光伏询盘为何需要用电负荷曲线

按时间分布的用电数据有助于讨论光伏与建筑需求的匹配。全年总量不能显示工作时段或休息日，应先明确计量边界、时区和数据质量；费用估算另需真实电价与假设。

实用核对清单

· 明确边界：确认数据涵盖的建筑与负荷，以及未来可能变化。

· 核对时间：注明间隔、时区、缺失期及夏令时处理。

· 说明运行规律：补充班次、停产、季节需求和设备变更。

· 比较明确情景：布局比较采用同一负荷数据，变化须说明。

需要澄清的情况

估算数据或混合无关负荷时应保留条件，不凭单张月账单承诺自用比例或回收期。
