Results Summary

Disclaimer
  • All results are estimates only and are provided for illustration purposes. They do not constitute a guarantee of actual electricity bills, solar generation, or cost savings.
  • Calculations are based on the current TNB tariff structure, the prevailing Solar ATAP policy, and the information provided by the user. Future changes to tariffs, policies, taxes, levies, or regulations may affect the actual results.
  • Estimated solar generation may vary due to factors including (but not limited to) roof size, design, orientation, tilt angle, shading, weather conditions, equipment performance, and system losses.
  • Actual savings depend on individual electricity consumption patterns, including monthly usage, daytime and nighttime consumption, occupancy, and future changes in electricity demand.
  • Unless otherwise stated, TNB bill calculations are based on the General (Non-Time-of-Use) tariff and exclude the Automatic Fuel Adjustment (AFA), which may vary monthly and result in either additional charges or rebates.
  • While reasonable care has been taken in preparing these estimates, Alpha Solar Sdn. Bhd. shall not be liable for any loss or damage arising from the use of or reliance on the results generated by this calculator.
