Leasing solar panels allows you to avoid the upfront costs and potentially provides lower monthly payments, but you don't own the system, and the savings may be less in the long term. Buying solar panels involves a larger initial investment but gives you full ownership, offering greater long-term savings and incentives. It also increases your property value. The choice depends on your financial situation, long-term plans, and how much you value owning the system outright versus saving upfront costs.
