The five stages

The five stages of the Black Glass Deal, with what we do and what you do at each
Stage What we do What you do
01 Roof assessment We assess structure, orientation, shading and energy use, then give you an indicative figure with the basis for each number. Share basic building details and give a surveyor access to the roof.
02 Agreement We set out the full terms in writing: term, payments, maintenance and what happens on a sale. Review the terms with your solicitor and accountant. Sign the funding agreement if they stand up.
03 Installation We arrange the funding, appoint and manage an accredited main contractor to install the system, and handle the grid connection and paperwork. Give roof access during installation. We agree timings and any tenant notice with you first.
04 Income We monitor and maintain the system for the term of the agreement. Sell the energy to your tenants and keep the margin after your fixed payments to the funding vehicle.
05 End of term Hand the system over. Ownership passes to you automatically, and your payments end. Keep everything it generates, and take over its maintenance.

Where the money goes

The roof earns.
Your payments go to the funding vehicle, not to us.

  1. Energy income

    You sell what the roof generates to your tenants, and any surplus is exported to the grid. If you occupy part of the building yourself, you can use the electricity there and buy less from the grid.

  2. Your payments

    There's no capital outlay, but there are payments. Over the term of the agreement you make fixed, scheduled payments to the funding vehicle that finances your installation. The energy income is designed to cover them, but the payments are due whatever the building earns, including during voids.

  3. Your margin

    What's left after your payments is yours, for the term of the agreement. The split varies by building and is shown in your assessment. We can provide an illustrative example for your building when you request an assessment.

How we're paid. Black Glass Capital doesn't receive your payments. We're paid by the funding vehicle: a development fee for each building and a maintenance fee for the life of the agreement.

Some qualifying projects may also receive an upfront payment. This is assessed case by case and is not part of every offer.

The usual arrangement

A typical Power Purchase Agreement puts solar on your roof
and the income in someone else's account.

Comparison of typical structures. Individual Power Purchase Agreement terms vary. Capital allowances may be available. Your accountant will confirm what applies to you.

The catch

What you commit to, before you ask.

There are obligations, and we'd rather you heard them from us. Your solicitor will see them all in the funding agreement.

  1. A long-term agreement

    The agreement runs for 20 to 25 years. You see every obligation in writing before you sign.

  2. Roof access

    For installation, and for maintenance during the term. We agree access arrangements with you in advance.

  3. Fixed payments

    You make fixed, scheduled payments to the funding vehicle for the term. The energy income is designed to cover them, but the payments are due whatever the building earns, including during voids.

  4. Your lender, if there is one

    If the building is mortgaged, your lender will usually need to consent. We help you prepare what they ask for.

Start with one building.
