Answer:
It will take 34.79 years before the solar panel is only able to produce 300 watts of power
Step-by-step explanation:
The equation for the amount of electricity that a solar panel is capable has the following format:
In which Q(t) is the amount after t years, Q(0) is the initial amount and k is the exponential decay constant.
After ten years, a solar panel produces 89% of the electricity that it was able to produce when it was brand new.
This means that . So
So
Initially capable of producing 450 watts of power
This means that
How long will it take before the solar panel is only able to produce 300 watts of power?
This is t for which Q(t) = 300. So
It will take 34.79 years before the solar panel is only able to produce 300 watts of power
