How Solar Works
Understanding the technology behind solar panels helps you make better decisions about system components and expected performance.
Solar panels use photovoltaic (PV) cells made from high-purity silicon to convert sunlight directly into electricity. When photons hit the silicon, they knock electrons loose, creating an electrical current.
Key System Components
Solar Panels
Convert sunlight to DC electricity. Tier 1 panels offer best performance and longevity.
23.1% efficiencyInverter
Converts DC to AC power. The brain of your system, syncing with Malaysia's 240V grid.
98% conversionMeter
Bi-directional meter tracks import/export for NEM 3.0 credits.
Real-time trackingMounting
Aluminum racking secures panels to your roof at optimal angle.
25-year ratedFinancial Benefits
Solar energy delivers strong financial returns while protecting against rising electricity costs.
NEM 3.0 Net Metering
Export excess solar generation and receive 1:1 unit credits on your electricity bill. Effectively use the grid as a free battery.
Inflation Protection
Lock in energy costs while TNB tariffs rise 4% annually.
Property Value
Solar adds 5-8% premium to Malaysian property valuations.
Carbon Reduction
Offset 1.5 tonnes of CO2 per kWp installed annually.
Energy Security
Reduce grid dependence and exposure to tariff volatility.
System Sizing
Right-sizing your system ensures maximum savings without overspending on unnecessary capacity.
The optimal system size depends on your electricity consumption, roof space, and budget. Modern sizing focuses on offsetting your highest tariff tiers first for maximum financial impact.
Consumption
Analyze daytime vs nighttime usage patterns.
Roof Area
South-facing orientation yields maximum capacity.
Future Load
Account for future EV charging needs.
As a rule of thumb, every RM 100 on your monthly electricity bill can be offset by approximately 1 kWp of solar capacity.

FAQ
Q.What is the ROI timeline for solar in 2026?
With rising tariffs and declining hardware costs, residential systems achieve full payback in 3.5 to 5 years, delivering 20+ years of essentially free electricity afterward.
Q.How does NEM 3.0 work?
NEM 3.0 provides 1:1 unit offset for 10 years. Every unit exported to the grid is credited at the same rate you buy electricity, making the grid a virtual battery.
Q.Will solar work during cloudy days?
Yes. While output is reduced, modern panels still generate 10-25% of rated capacity on overcast days. Annual averages account for weather variability.
