How Should PV Energy Model Inputs and Revisions Be Recorded

Keep an input log with each energy estimate so another reviewer can understand what changed. Identify the weather data source, layout, electrical equipment, shading treatment and loss assumptions. The log supports a comparison; it is not a production guarantee or a substitute for reviewing the model itself.

Practical review checklist

· Freeze the scenario. Name the layout, product models, inverter concept and simulation revision used for the estimate.

· Identify evidence. Mark which inputs came from measured records, manufacturer documents or a model default.

· Explain changes. Compare revisions with a change log rather than replacing an output total without context.

· Describe uncertainty. Ask the analyst to state missing inputs and the conditions that would change the result.

When to request clarification

A result should remain provisional when major inputs cannot be traced. Avoid presenting a model default as a verified X-SOLAR operating characteristic.

Questions buyers ask

Does a higher simulated result prove a better proposal? Only a comparison with consistent, disclosed assumptions can support that discussion.

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 model summaries, source references, layout revisions and the decision the estimate is intended to support.

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.

光伏发电量模型输入与版本应怎样记录

每份发电量估算应附输入表，使审阅者理解变化来自哪里。记录气象来源、布局、电气设备、遮挡处理及损失假设；输入表支持比较，不是发电保证或模型审查替代品。

实用核对清单

· 固定情景：明确布局、型号、逆变器方案及模拟版本。

· 标识来源：区分实测、制造商资料和模型默认输入。

· 解释变化：用变更表比较版本，不仅替换总发电数字。

· 说明不确定性：由分析者列明缺失输入及可能改变结果的条件。

需要澄清的情况

主要输入不可追溯时结果应为暂定，不把模型默认值写成已核实的X-SOLAR运行特性。
