Biting the bullet to go solar can be a big decision. Not too many people have that kind of money to invest all at once. Yet, today there are numerous ways to finance a PV solar system if you are lacking the total funds up front.
Once that investment has been paid you can enjoy the benefit of your own private power plant for the next 25 to 30 years . . . . without any additional costs. Meanwhile, your power utility continues to raise your electrical rates on a regular basis. Over the course of 20 years it is conceivable that you will pay up to twice as much for utility power versus having your own PV solar array.
The Sauser household is in the process of having a 7.5kW roof top solar array installed. We have managed to reduce our monthly kWh consumption to be covered by a 7.5kW PV system. We should be able to generate enough power to satisfy our monthly electrical needs. On paper, we believe we can achieve Net Zero in our humble 3-bedroom home. The future of Net Zero is in the ability to retrofit existing homes to come as close to Net Zero as possible. The transition of our home to Net Zero will serve as the primary case study for my next book: Retrofit to Net Zero.
