Turn your roof into a power station.

For a typical Selangor semi-D with a monthly bill of RM 350–500, a 6 kWp system saves RM 200–360 per month through direct consumption offset and NEM credits. Actual savings depend on your daytime usage profile — households that use more electricity in the daytime (work-from-home, etc.) see higher direct savings. We model this precisely from your last 12 months of TNB bills during the free assessment.

Most pitched roofs in Selangor are suitable. The key factors are orientation (south or west-facing is optimal), shading from trees or adjacent buildings, and structural load capacity. Our engineers assess all of this during the free site survey. Flat concrete roofs can use racking systems to achieve the optimal tilt angle.

Net Energy Metering (NEM) is a programme under the Malaysian Sustainable Energy Development Authority (SEDA) that allows your solar system to export excess electricity to the TNB grid and receive a credit at the same rate you pay for electricity. The credit rolls over each month and reduces your next bill. You apply once — Helios handles the entire NEM application and TNB liaison process.

Solar panels have no moving parts and require very little maintenance. Rinsing with water two or three times a year removes dust and bird droppings that can reduce output by 5–10%. The inverter has an expected service life of 10–12 years. We provide a remote monitoring app so you can track daily generation and flag any unusual drop in output.

Yes — green hire-purchase is available through CIMB, Maybank, and Public Bank at 2.88–3.88% p.a. effective over 5–7 years. For a 6 kWp system at RM 22,000, the monthly repayment is around RM 300–340 — often lower than the monthly savings the system generates. We assist with the loan application and documentation.
