The Cost and Benefits of Solar in Willowbrook
While solar panels can help save you a decent chunk of change on energy bills over time, it's necessary to take into consideration the startup costs. Some significant things that influence the upfront cost and potential savings over time include:
- Incentives: Those who buy and install a solar system this year can save 30% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $27,000 on your electricity bills over 20 years not including incentives.
- The amount of sunlight your area gets: Thanks to Willowbrook's very high amount of average daily sunlight, you should be able to save a lot on your energy bills.
- Electricity consumption: The average home in Willowbrook doesn't use much energy, and consequently may not see as many savings on their power bills.
- Choice of solar panels: The kind of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If you don't need to maximize efficiency, you can go with a higher number of more affordable panels.
So is a solar panel system worth it? Whether you want to reduce your energy bills, carbon dioxide emissions or both, solar panels are a worthwhile investment for many Willowbrook homeowners.
