What applies to this exact problem

Pay cash and keep a healthy emergency fund

Cash avoids loan interest and fees. Use it when the remaining liquidity still covers foreseeable household needs.

Cash payment would drain reserves

Compare a partial down payment or loan. Paying financing cost can be rational if the alternative is having no emergency buffer.

Loan APR is high relative to conservative savings

Do not justify the loan with optimistic generation. Rework system size, price or financing.

Subsidy is not yet approved

Run the case at zero subsidy. Treat later receipt as upside, not required cash flow.
