FAQ

Questions we often get.

Can't find your answer? Ask our team.

How much can I save?

Homes: solar works best when your TNB bill is around RM300 a month or more, because that's when you're paying the higher tariff blocks that solar replaces. A well-sized system typically cuts a home's bill by 40% to 70%, and more if someone is home during the day. Send us your last three TNB bills and we'll give you a realistic estimate, not a best-case number.

Businesses: we study your last 12 months of TNB bills to understand your load profile and maximum demand. That tells us the right system size, and whether adding a Battery Energy Storage System (BESS) would increase your savings.

How much does a system cost?

Every system is quoted case by case, because no two roofs or electricity bills are the same. Your price depends on the system size we recommend from your usage, your roof type and structure, the panels and inverter used, and whether you add a battery.

A battery raises the upfront cost but can increase your savings or give you backup power, so we'll show you both options where it makes sense. After a free assessment, you'll get an itemised proposal so you can see exactly what you're paying for.

Is my roof suitable?

Most landed homes and commercial roofs are. Orientation, shading and roof condition matter, which is why we inspect before we design. If the roof needs repairs first, we'll tell you.

How long does the whole process take?

Once your installation date is confirmed, installation takes 1–2 days on site, depending on system size.

Authority approvals, TNB meter installation and commissioning take longer: about 3–4 weeks for most homes, and up to 3 months for commercial and industrial systems, depending on size and complexity. We handle the paperwork and keep you updated at every stage.

Does solar work on cloudy or rainy days?

Yes. Panels keep generating from diffuse light on cloudy days, just at lower output, and our savings estimates are based on Malaysia's year-round weather, so cloudy and rainy days are already accounted for.

We use tier-1 bifacial panels, which also capture light reflected onto their rear side. The extra yield depends on how they're mounted: modest on pitched home roofs, and higher on light-coloured metal or flat commercial roofs where panels sit further from the surface.

Do I need a battery?

Not necessarily. It depends on how and when you use electricity, and we'll advise you based on your bills.

Homes: a battery stores surplus daytime solar so you can use it at night, and can keep essentials running during a power outage. Because unused export credits don't carry over under Solar ATAP, storing your own power can increase savings for some households. If a battery doesn't pay off for you yet, we can make your system battery-ready so you can add one later.

Businesses: a Battery Energy Storage System (BESS) can be used for peak shaving: releasing stored energy during your highest-demand periods to lower your maximum demand (MD) charges, which can be a significant part of a commercial electricity bill. See how battery storage works.

What warranties do I get?

Panels: manufacturer product and performance warranties of up to 25–30 years, depending on the model.
Inverters: manufacturer warranty of up to 10 years.
Installation: our own 5-year workmanship warranty.

What maintenance do you provide?

Every installation includes 3 scheduled inspection and panel-cleaning visits, plus performance monitoring so we can spot and fix issues early.
