What is the most reputable solar installer in Marrero?
The highest-rated local solar company in Marrero is PosiGen Green Grants, with a rating of 5.00 stars.
What are the best and worst things about solar power?
The biggest advantages of solar power are that it can reduce or, in some cases, totally cut your electricity bills, raise the value of your home and reduce your carbon footprint. The biggest disadvantages are that solar panels can be pricey to install, you may not see as many savings if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.
Are solar panels worth it?
Solar panels can be a great investment for many homeowners, but admittedly, 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 fairly low, solar panels might not be for you.
How often do solar panels need to be replaced?
On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
