The project

You join Calverdon Energy Installations Ltd (simulated company)

Calverdon Energy Installations Ltd (simulated company) is a solar and ev charging installer in Manchester. You help its team deliver a project for Ardmoor Logistics Ltd (simulated company), at Ardmoor Park Depot: warehouse roof and staff car park.

Ardmoor Logistics wants solar on its warehouse roof and six EV charge points in the car park, on the supply it already has. You join Calverdon's design team in week one with a half-checked string design. In the first week you size strings for the coldest morning, review a draft, size the AC cable and work out how six chargers share 100 A. Later, the network operator limits export to 15 kW, the client adds two chargers, a string tests low, a wet insulation reading comes in under pressure to sign, and the client asks to skip the protection that guards against a lost PEN conductor.

The people in the story are roles, such as Lead Engineer, not real people.

What you will do

By the end you will have

  • Size PV strings with cold-temperature voltage and check the inverter window
  • Size DC and AC cables for current and voltage drop, and decide on string fuses
  • Choose the grid connection route and handle a network export limit
  • Share a limited supply between EV chargers with load management
  • Test strings to IEC 62446-1, record failures honestly and hand over safely

Questions

Quick answers

Do I need PV design software?

No. The work is done in the browser with worked calculations, tables and the 3D solar and EV lab.

Which standards does it follow?

It follows the ideas of IEC 62548, IEC 62446-1, IEC 61851-1, BS 7671 and the G98 and G99 routes. Cable data in the exercise is simplified.

How long does the free week take?

About nine hours of active work over five working days.

What does the Premium edition add?

The full four-week project: the export limit change, string tests, wet-weather and safety decisions, a capstone pack reviewed by an engineer and an AI viva.

Is this a real job?

No. It is a job simulation at a simulated company. It is not employment.

Is the Solar PV and EV Charging Engineer job simulation free?

Yes, to start. Days 1 to 5 are free. The certificate and the Premium edition are optional and are priced on this page in your currency.

Does it count as work experience?

It shows on your EDWartens profile under Work experience, marked as a job simulation. It is not employment. A job simulation is a realistic training project at a simulated company. It is not employment, an internship or a work placement. Hours are active hours the learner logged on EDWartens.
