The Cost and Benefits of Solar in Lake San Marcos
The cost of putting up solar panels has decreased immensely in the past few years, but it's still a significant investment for most homeowners. Some key things that determine the cost and possible savings include:
- How much sunlight your roof gets: If your rooftop doesn't see much direct sunlight, your solar system won't be able to make as much energy, which will leave you with lower savings on energy bills than a house with a roof that gets plenty of sunlight.
- Incentives: One thing 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 utility bills, which can lead to an average of $31,000 of savings over 20 years.
- The cost of electricity in your area: If your local power rates are high, there's a better chance you'll get a higher return on your investment in a solar system. In Lake San Marcos, you can save an average of $77 a month on your electricity bills.
- The type of solar panels you can afford: This hinges on what your budget is.
So is buying solar panels worth it? Whether you hope to lower your electric bills, carbon emissions or both, solar panels are a worthwhile investment for many Lake San Marcos homeowners.
