The Cost and Benefits of Solar in New Castle

- The amount of sunlight your roof gets: If your rooftop doesn't get a lot of direct sunlight, your solar panels won't be able to produce as much energy, which will leave you with lower savings on power bills than someone with a roof that gets a lot of sunlight.
- Your income and budget: This affects what kind of solar panels you can afford.
