The Cost and Benefits of Solar in Greenwich
We understand that for lots of homeowners, the choice to invest in solar rests on installation costs. There are quite a few factors you should take into consideration when trying to determine the overall cost and how much you can save, such as:
- The kind of solar panels you want to get: More efficient panels are more expensive, so that will influence your budget for your solar project.
- Incentives: Something that can save you money on your solar project 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 utility bills, which can give you an average of $24,000 of savings over 20 years.
- How much you spend on energy: The typical family in Greenwich spends around $1,100 a year on home energy use alone, so you could gain that much in savings.
- Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
Though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, including the angle of your roof and incentives.
