From the engineering practice

AI engineering assistant for solar PV and battery storage

Send us a project, or a document you already have. The assistant makes the first pass on sizing, yield and storage configuration, and a practising engineer checks it before it reaches you. The first look at a document you already have is free.

What comes back

A written assessment you can hand to your own team, with the reasoning visible rather than hidden behind a number.

  • Assumptions stated in every report
  • Every figure traceable to a formula or a cited source
  • Read and corrected by a practising engineer before it is sent

Example output
System size1,050 kWp
Specific yield (P50)1,320 kWh/kWp
Module count2,500
InverterString, 1,500 V DC
Storage2 MWh LiFePO4

Illustrative figures for a sample project. Every real assessment states its own inputs and loss assumptions.

The engineering is not the slow part

Most of the week goes on assembling inputs and writing the document. That is the part we automated first.

Preparation takes days

Collecting site data, running the first sizing pass and writing it up eats the week before the proposal is even drafted.

Calculations live in spreadsheets

Every project rebuilds the same workbook. Errors carry forward and nobody can see which cell they came from.

Proposals are slow to write

The engineering is done in hours, the document takes days, and the client is comparing you against someone who answered first.

Engineering capacity is the ceiling

Taking on more projects means hiring, and hiring an engineer takes longer than the tender is open.

What it produces

Four outputs, each one a document the next stage can use.

Solar PV sizing

Preliminary system sizing, module count, inverter configuration and an annual energy estimate with the loss assumptions written out.

Storage configuration

Power-to-energy ratio, round-trip efficiency and duty cycle for the case the project actually sells into, not a generic profile.

Document analysis

Electricity bills, datasheets, single-line drawings and specifications read and turned into the inputs the assessment needs.

Report generation

A structured technical report you can put in front of a client, with each figure traceable to a formula or a cited source.

How it works

The assistant is fast. The engineer is why you can send the result to a client.

01

Send the project

Location, consumption, drawings, datasheets, and what the assessment is for.

02

The assistant runs the first pass

Sizing, yield, storage configuration and cost build-up, using the same method we apply on our own projects.

03

An engineer reviews it

Nothing leaves the practice unread. A practising engineer checks the assumptions and corrects what the model got wrong.

04

You get the report

A written assessment with the assumptions stated, ready for engineering review or for a client conversation.

Who it is for

Companies that need an engineering answer faster than they can staff for one.

Solar EPC companies

Answer tenders faster without adding engineering headcount.

Storage developers

Get a defensible first sizing and configuration before committing to a design.

Electrical contractors

Produce a technical proposal when there is no engineer on staff to write one.

Energy consultants

Turn a feasibility question into a consistent, documented assessment.

Send us a project

Tell us what you are building, or send something you already have — a yield model, a report, a design package. The first look is free: within two business days you get a written note on what we would check first and why.

Drawings, yield models and datasheets go by email after we reply — nothing is uploaded here.

The first look is free

Send us something you already have — a yield model, a UL 9540A report, a design package or a capital estimate. Within two business days you get a written note naming the first things we would check and why. No charge, no obligation.

What you get

  • ✓A written note, not a sales call
  • ✓The first things we would check, and what each one could change
  • ✓Whether the document would survive a lender or a grant reviewer
  • ✓What we would need from you to take it further
  • ✓Written by a practising engineer, not generated

What we ask in return

Nothing for the first look. If it turns into real work worth writing up, we will ask permission to publish it as an anonymised case study — no company name, no exact location, no commercial terms, and you see the text first.

We take a limited number of these at a time, so the queue moves in order.

The engineering behind the assistant

It was built from the way we work on our own projects, not from a generic model of what solar engineering looks like.
