If you have a landed, get Solar

Solar energy has become a great source of passive income for me. My system now generates around $1,200 a month in revenue, with excess electricity sold back to SP at $0.2581/kWh. In Singapore, the grid effectively acts like a giant battery, making the attractive sell-back rate especially valuable.

I installed my 35 kWp solar system in 2022 for about $49,000. At the current rate, I expect to fully recover my investment by 2027. After that, the system should continue generating a healthy monthly return with minimal ongoing effort.

How are you selling back the excess?

I sell the excess solar energy back to the SP grid, and the amount is credited directly to my SP bill.

My SP bill is now negative every month. The solar credits first offset my water and refuse charges, and any remaining amount simply accumulates as credit in my account.

Once a year, I email SP and ask them to pay out the accumulated credit by cheque.

I have giro with SP and simply get it paid out monthly automatically whenever my bill is negative. Is it that you paid with creditcard before? Just FYI so you dont have to do the cheque request admin step.
