EcoWatch's Destrehan, LA Solar Cost FAQs
How much does it cost to install solar panels in Destrehan?
This is a difficult question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $19,000 for a 5-kW system and $38,000 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy usage. On the flip side, you can spend less if you choose a smaller solar panel system or cheaper solar panels.
Can you get solar panels for free in Destrehan?
Solar panels aren’t free in Destrehan, but there are some options that can make getting them more viable, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can help lower the cost.
How much can I save on electricity bills after installing solar panels?
It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Destrehan, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.
How long do solar panels last in Destrehan?
Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is how much energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
