Why Invest in Solar?
Solar energy is one of the safest investment options on the market today, delivering:
- 100% guaranteed financial return on investment (you get all of your money back, then an 'annuity' for decades in the form of avoided electricity costs)
- Environmental return on investment (eliminate thousands of pounds of CO2 emissions annually)
- Home equity return on investment (solar is proven to increase the value of any property by lowering cost of ownership)
- Community return on investment (everyone benefits from cleaner air & reduced dependence on fossil energy)
