The Cost and Benefits of Solar in Harlingen
When picking a solar company, most homeowners or business owners wonder about the costs above all. The cost of solar and the savings it generates vary depending on some key factors such as:
- Choice of solar panels: The type of solar panels you choose 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 space isn't a constraint for your project, you can go with a higher number of more affordable panels.
- Energy consumption: Solar may be too steep of an investment for homes that don't consume too much energy per month.
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 30% of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $17,000 over 20 years on your energy bills.
- The amount of sunlight your home gets: Thanks to Harlingen's very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
So is a solar system worth it? Whether you're trying to decrease your energy bills, carbon emissions or both, solar panels are a solid investment for many Harlingen homeowners.

Environmental Impact of Switching to Solar in Harlingen
Making the switch to solar power is a profound way to do what you can for a cleaner and more sustainable future. A question many might have in mind is how much can they really help save the environment by switching to solar power anyway? Your energy usage is a key factor to think about. The more electricity your home uses, the bigger your impact when you make the switch to solar power. In fact, if you adopt solar power, you could be looking at reducing your carbon dioxide emissions by about 90 pounds each year. For homeowners who care about the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.

What are the advantages and disadvantages of solar power?
A few of the biggest pros are that it lets you spend less on your power bills, it's good for the environment, and it can give you a good return on your investment (ROI). The most notable cons are that solar panels don't work as well when there's limited direct sunlight, they cost a lot upfront and solar panels aren't always aesthetically pleasing.
Is it worth installing solar panels on my house?
Solar panels can be a beneficial investment for most homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already reasonably low, solar panels might not be for you.
What is solar panel capacity and how much do I need for my house?
Solar panel capacity is rated based on how many watts of power they produce under standard testing conditions. Since each panel can typically produce about 250 to 400 watts per hour, the average household will need 20 to 35 panels.
