Assalamualaikum, The 0% escalator option with an IGS Solar lease means that it solar lease payment never increases for the entire term of the agreement (typically 25 yrs). Instead of ur payment rising every year (such as 2.9%), it stays exactly the same from first payment to the last. OKay 2 work?

Ustadh AbdulAziz al-Haqqan

JazākAllāhu khayran for your question. A payment staying fixed is not, by itself, what decides whether the lease is permissible — the contract's structure is.
