EcoWatch's Denville, NJ Solar Company Rankings FAQs
What is the most reputable solar panel installer in Denville?
The highest-rated local solar company in Denville is Phoenix Energy, with a rating of 5.00 stars.
What are the advantages and disadvantages of solar power?
A few of the biggest pros are that it reduces your power bills, it's good for the environment, and it gives you a decent return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, they cost a lot upfront and solar panels aren't always aesthetically pleasing.
How long does it take for solar to pay for itself?
Solar panels generally pay for themselves in about 13.9 years, but your solar payback period will vary depending on your utility costs. The more your typical power bill, the quicker your solar panel system will pay for itself.
How long do solar panels last?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is their energy production will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.
