The Cost and Benefits of Solar in Wilmington

The cost of putting up a solar panel system has decreased greatly over the past few years, but it's still a large investment for most homeowners. The cost and possible savings vary depending on a few key factors such as:

  • Your city: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your power bills, which can give you an average of $14,000 of savings over 20 years.
  • How much energy you use: If your home needs to use a lot of energy, you'll benefit more from installing solar panels.
  • Choice of solar panels: The type of solar panels you choose 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 space isn't a constraint for your project, you can go with a higher number of more affordable panels.

As a result of solar panels now being cheaper than ever as well as various solar incentives, they are a worthwhile investment for many homeowners.

EcoWatch's Wilmington, DE Solar Company Rankings FAQs

Which solar power company is the best in Wilmington?

In Wilmington, GreenBrilliance is the best local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're looking to install solar panels on your roof.

Are solar panels actually environmentally friendly?

Solar panels can be bad for the environment when manufacturers use toxic chemicals when they're made. Chemicals can make solar panels difficult to recycle safely once they've reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take for solar to pay for itself?

Solar panels generally pay for themselves in about 12.1 years, but your solar payback period will vary based on your utility costs. The higher your typical power bill, the faster your solar panel system will recoup your installation costs.

What is solar panel capacity and how much do I need for my house?

Solar panel capacity is rated based on the amount of power they generate under standard testing conditions. Since each panel can generally produce about 250 to 400 watts per hour, the average house will need 20 to 35 panels.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
