Why passing clouds and rainy seasons won’t hurt your savings.
One of the biggest worries people have about solar panels in a tropical place like Kuching or Miri is the weather. “What happens during the monsoon season when it rains for a week straight? Am I just wasting my money?”
To answer that, we have to look at how Sarawak Energy handles your extra solar power. When your roof generates energy during a hot, sunny afternoon, a special two-way meter sends the extra electricity back to the grid. SESCO trades this with you on a 1-to-1 basis—every unit you give them is credited against your bill.
But here is the secret feature that makes Sarawak’s system vastly superior to what they have in Peninsular Malaysia: SESCO’s solar credits roll over month-to-month and don’t instantly expire.
Think of it like a rollover data plan for your phone:
During our scorching hot months (like May to August), your roof will produce way more energy than your home can use. SESCO safely banks all those extra credits into your account. When the heavy rainy season hits later in the year and the sky turns grey, your system slows down—but you simply draw from the massive pile of “stored credits” you built up during the summer to wipe down your bill!
It creates a perfect year-round buffer, meaning passing clouds never ruin your long-term savings plan.
