Switching to solar power has huge benefits which are:

  • Guarantees energy reliability, security and independence

  • Up to 50% cost savings on monthly power bills

  • Hassle free low maintenance

  • Almost 20 years of FREE electricity generation as payback period is 4-6 years

  • Adds value to property

  • Sets an example for kids and society by demonstrating benefits

  • Reduces carbon footprint substantially
