Before you install
Questions to ask before going solar.
Solar ATAP, system size, roofs, batteries, and maintenance.
Where is Just Solar by 0x?
The office is at 18-G, Jalan Radin Tengah, Bandar Baru Sri Petaling, 57000 Kuala Lumpur, Wilayah Persekutuan Kuala Lumpur. Installations are carried out across Kuala Lumpur and Selangor.
What is Solar ATAP?
Solar ATAP is the programme for connecting rooftop solar to the TNB grid in Peninsular Malaysia. It continues from NEM, which ended in June 2025. You use your solar energy first, and any surplus exported to the grid earns credits on that month’s bill.
How big can a home system be?
Under Solar ATAP, homes on single-phase supply can install up to 5 kW and homes on three-phase supply up to 15 kW. Larger systems need a TNB technical check first.
Does unused export carry over to next month?
No. Under Solar ATAP, exported energy is credited within the same billing month only. That is why systems are usually sized close to your daytime use.
Are prices listed online?
No. The price depends on system size, roof type, mounting, inverter, and any battery or charger. A quote follows the site assessment.
Is my roof suitable?
Most tiled, metal-deck, and flat concrete roofs can take panels. Direction, shading, and roof condition matter most. The site assessment checks all three.
Do panels need cleaning?
Rain helps, but dust, haze residue, and bird droppings still build up. Many owners clean panels once or twice a year, more often near roads or construction.
Can businesses install larger systems?
Yes. Non-domestic accounts can install up to 100% of their maximum demand, to a limit of 1 MW, subject to TNB technical assessment. Exported energy is credited at the average system marginal price.
Is Just Solar by 0x the same as 0xDIGITAL?
No. Just Solar by 0x is an independently operated solar installation business. This website is published as an authorized partner website by 0xDIGITAL.
