Independent advisory

On every project we take one of two roles, never both. As independent advisor we are paid a fee, earn nothing on hardware and take no commission from manufacturers or installers.

Independent advisory

We are paid by fee, with no margin on hardware.

Advisory work runs in seven steps, from the first look at your load profile, the record of your site’s power demand over the year, to the acceptance test of the finished system. Each step is priced on its own scope, so you can stop after any of them.

Fee only

No margin on hardware, no commissions

7 steps

From load profile to acceptance test

Specification and tendering

We write the specification before any installer sees the project, so every bid you receive answers the same document and prices the same scope.

Specification and tendering

One specification makes the bids comparable.

Bids only become comparable when a specification written to standard exists before anyone prices the work. If we wrote the tender, we do not bid on it ourselves.

Owner's engineering and acceptance

We review the contractor’s design before you sign it and run the acceptance test before you pay, so the risk sits with the party who can actually judge it.

Owner's engineering

We work as your engineer on the project, never for the installer.

A design review before you sign catches problems while they are still cheap to fix. An acceptance test before you pay confirms that what was promised was actually built.

Turnkey delivery

If you want one contract instead of coordinating your own contractors, we deliver the system through vetted installation partners under our supervision.

Turnkey delivery

One contract covers the whole system.

Engineering, procurement and installation sit under one contract, delivered through vetted installation partners. We have no own installation team. We take the turnkey role only where we did not write the specification or evaluate the bids.
