Hi, I don't think it will give you any benefit financially. Not anytime soon, anyhow. Unless our electricity tariffs increase, or that the government decide to restart the FiT scheme again (in which they pay you in cash for excess electricity). Currently, what you can expect is that you are only paying GSparx for leasing the panels, and instead of paying TNB the same amount (RM250-350) you are paying for the lease while getting electricity. Once the lease is up, then only you will see the benefits.

Generally speaking, unless your electricity bills are in the region of RM300-400, there is no substantial benefit. Just that you are doing something good for the environment. Or if you are using that solar power to generate income (BitCoin, as someone is doing on this thread). GSparx is coming over to review my house this weekend, if you are interested, send me a PM.
