Here, I want to explain a problem. If the equity is pledged to you, you actually only have the right to dispose of these equity. Before the project agreement is paid, you don't have the shareholder rights that the actual equity should have, that is, you are actually a creditor, not a shareholder, and the creditor only has the right to repay the debt.
So you need additional binding terms, such as an agreement with the financier that one of the partners of your fund should send a director and have a veto power on major issues. But if it rises to the level of company law, you actually don't have this right, you can only bind it separately, and it is best to be appraised by a lawyer.
The best way is that you can directly purchase 5 1% equity of the project party with loan funds, agree to repurchase and pledge the remaining 49%. In this way, you have exercised both the right of disposition and the equity. According to the relevant aspects of equity, you can send directors reasonably and legally. As a major shareholder, you can enjoy a veto on the board of directors.
