Milestone Disbursements

This article will cover Wunder's policy and procedures regarding disbursement of funds during the construction phase of a loan including who is eligible to receive this benefit, how much capital is available at each milestone, and how Wunder defines and verifies milestone achievement.

Note: Wunder does not offer stand-alone construction financing and can only offer milestone disbursement schedules to select partners working on projects for which Wunder will be providing long-term project financing. 

Partner Eligibility

The primary factors that determine whether a contractor will be eligible for Milestone Disbursements are their experience building solar (MW built + years in business) and their history working with Wunder.

In order to substantiate a partner's experience, Wunder will often require one or more of the following: inspection of a previously built system, collection and analysis of output from past completed systems, reference letters, independent engineering reviews, and more. In addition, Wunder may also review all subcontractors completing work on the project. 


Availability of Funds

Wunder has defined four project milestones for which a project may be eligible. The Disbursement Schedule will be discussed during the project diligence phase and agreed to during contracting. Availability of funds is based on the following schedule:

Milestone Available Funds
Equipment Procurement Up to 90%*
Mechanical Completion 70%
Substantial Completion 90%
Permission to Operate 100%

*Original invoices for all equipment must be provided in order for funds to be released. At least 70% of total disbursed capital in this stage must be used for the purchase of panels and/or inverters.

Please note that regardless of the contracted disbursement schedule, funds are never available before the contracted Capital Access Date. See the Capital Disbursement article for more information Wunder's process for releasing funds.
