After the course

After the course — into real work

Upload or fill in your CV and choose which employers you want to apply to. Once you confirm, our team sends your application to the selected grid operators and/or leading companies in the photovoltaic sector.

Apply for a job

Choose grid operators, leading solar companies or both, then upload or fill in your CV.

Or work directly with customers

If you would rather work directly with end customers, you can build a professional profile on the technician map, so people looking for a solar specialist can get in touch with you.

Go to the technician map

We forward your application to the employers you choose. The hiring decision is theirs — we do not promise a job or customers.

1SunSunlight
01Sun

Sunlight

It all starts at the sun. Photons hit the surface of the panel — even on a cloudy day there is useful radiation.

02DC

Solar panels

The photovoltaic array turns light into direct current (DC). The more panels there are, and the better they face the sun, the more energy.

03AC

Inverter

The inverter turns direct current into alternating current (AC) — the same current the appliances in your home run on. The heart of the system.

04Home

Consumer / house

The energy produced powers the house first. Air conditioning, water heater, lighting — everything runs straight off your roof.

05Grid

The electricity grid

The surplus flows back to the grid through a bidirectional meter. When the sun sets you draw it back — the balance always works in your favour.

Why solar

Four reasons that pay for themselves.

Not marketing — an effect you see on the bill and in the value of the property.

up to 70%less from the grid

Lower electricity bills

You generate your own energy and buy far less from the grid. The investment pays back in years, not decades.

0emissions in operation

Clean, green energy

Every kilowatt-hour you generate is carbon you did not emit. Energy from the sun, with no noise and no emissions.

24/7with a storage system

Energy independence

With a battery and a hybrid inverter you keep power through a grid outage. Less exposure to prices and to failures.

+market value

Higher property value

A property with a working photovoltaic system sells faster and at a better price. The asset earns while you live in it.
