The Cost and Benefits of Solar in Diamond Bar

  • How much sunlight your roof gets: This, along with how your roof is set up, affects affect how much electricity your solar panels can produce.
  • Electricity consumption: The average home in Diamond Bar doesn't use much energy, and so may not see as many savings on their power bills.
  • The kind of solar panels you're planning on getting: More efficient panels are more highly priced, so that will influence your budget for your solar project.
  • Incentives: Something that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save a decent amount of money on your energy bills, which can lead to an average of $25,000 of savings over 20 years.

Many want to do their part to help save the planet, which for many is the prime reason for installing a solar system. Something many homeowners might be asking themselves is how much can they really help the environment by going solar anyway? The average person has a considerable carbon footprint. Between their car, which is responsible for over 10,000 pounds of carbon dioxide emissions a year, and energy for their home, it can be overwhelming to think about what to do. Installing solar panels is a simple thing you can do to help. In fact, if you make the switch to solar power, you could look forward to lowering your carbon dioxide emissions by about 50 pounds each year.
