What is the role of the SNC token in this process?
SNC tokens are the utility tokens for all transactions on the SunContract platform. When you own an NFT, the revenue generated by the underlying solar panel is paid out in SNC tokens. These tokens can be used for energy trading on the platform (if you are in a supported country) or to buy additional NFTs, or you can cash out and exchange them for fiat anywhere where the SNC tokens are traded.
What happens if my solar panel needs to be repaired or replaced?
All solar panels are insured and will be taken care of for any repairs without charging you anything.
What happens after the NFT expires?
The NFT will stop generating money, but it will remain in your wallet for future rights or benefits from our projects. It is your proof that you are part of the global energy marketplace in SunContract’s Ecosystem, having been an NFT holder.
