Solar panels experience a small, gradual decline in maximum production capability as they age. This is known as panel degradation and is a normal characteristic of solar equipment.
Your PPA accounts for this expected change in performance when forecasting your system’s production over its 25-year term.
This does not mean Daylight intentionally reduces the electricity supplied to your home.
It means the long-term production schedule accounts for how solar equipment is expected to perform as it ages rather than assuming an older panel will perform identically to a new one.
Does this mean my electricity needs are expected to decrease?
No.
Your system’s production and your home’s electricity consumption are separate.
Your electricity usage may increase or decrease over time because of additional occupants, electric vehicles, heating and cooling equipment, appliances, renovations, or changes in how you use energy.
Your Production Guarantee protects you against the Daylight system underperforming the Guaranteed Production schedule in your PPA. It does not guarantee that your household’s electricity consumption will remain the same.
