Hi to all! I am a web and smart contract developer, crypto enthusiast and I want to support the trend of transition to green energy.

The main idea is that investors can buy tokens, which give the right to own the number of megawatts at the built solar station.
Holders of these tokens will receive income from generated solar energy.
The owner of the contract can withdraw borrowed funds (eth or bnb, depending on the blockchain) for the building of solar stations, and then return these funds to investors from the income.

Now I'm looking for a logical solution to how I can guarantee the fulfillment of obligations using a smart contract.
Please, share your thoughts on this with me.
