The Cost and Benefits of Solar in New Castle
We get that for most homeowners, the decision to invest in solar comes down to installation costs. A few key factors that affect the cost of installing solar panels on your home and how much money you could save over time are:
- How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panels won't be able to make as much energy, which will give you lower savings on electricity bills than a house with a roof that gets a lot of sunlight.
- Your home's power bills: Due to fairly high monthly electric bills in New Castle, you could save about $1,100 a year with solar.
- Choice of solar panels: The kind of solar panels you need will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don't need to maximize efficiency, you can opt for a higher number of more affordable panels.
- Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 30% of the project cost. Your state may also have various incentives that you can take advantage of. Plus, you can save about $16,000 over 20 years on your utility bills, before factoring in incentives.
There are lots of great benefits of solar in spite of the initial cost of installation. It can help the planet and your finances. In addition, it can increase the value of your home, leading to even more benefits if you want to sell your home later.

EcoWatch's New Castle, DE Solar Company Rankings FAQs
Which solar company is the best near me?
The highest-rated local solar company in New Castle is GreenBrilliance, with a rating of 5.00 stars.
Are solar panels really bad for the environment?
Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle safely once they've reached the end of their lifespan. Making solar panels uses a lot of energy as well. The energy payback period is about 1 to 4 years.
Is it worth installing solar panels on my house?
Solar panels can be a great investment for many homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your electricity bills are already fairly low, solar panels might not be for you.
What is the best type of solar panel?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and desired energy output.
