Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Installing solar panels can cut your electricity costs and help the environment by reducing your carbon footprint. When evaluating if a solar provider is right for you, consider these key factors.
It's important to hire a licensed solar installer. This helps ensure that the work is done correctly using the most up-to-date installation methods. In Louisiana, contractors can earn a solar energy endorsement or classification, on their contracting license. To do this, they need to obtain electrical, mechanical, or building endorsements first, then take a written test or prove their certification with North American Board of Certified Energy Practitioners (NABCEP).
Look at review platforms such as TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to find out what previous customers are saying about local solar companies. Reviews can give you an idea of a company’s dependability and customer service. Be wary of companies lacking reviews or with predominantly negative feedback.
To find a solar company that fits your budget, get free, detailed quotes from 3–5 providers. The quotes should list all costs as well as all solar equipment included. Looking at several quotes helps you identify the best value.
Top-notch solar installations should come with strong workmanship and performance warranties. A workmanship guarantee covers installation issues, such as cracks in the panels, poor wiring, or poor alignment. A performance warranty ensures a minimum energy output. Comprehensive guarantees show that a solar company believes in its work.
Solar energy can help decrease your electric bills over time. When evaluating the total price and value of solar panels, make sure to consider these factors.
The average Gretna homeowner will spend around $26,333 on a home solar system after federal tax refunds. Solar arrays in Gretna cost approximately $3,800 per kilowatt, with an average size of 9.9 kilowatts. A personalized estimate from a local solar provider will include costs for permit fees, labor, and preliminary work, and will account for your system's size, capacity, and panel type. Some homeowners prefer to lease their solar panels in order to reduce upfront costs.

A solar photovoltaic (PV) array can generate power to run any electric system or appliance in your home. A more specific example is installing a solar heating system for your water.
There are many advantages of home solar energy. You can reduce emissions, qualify for tax benefits, and save money. With the right storage equipment, solar panels can also give you further energy independence and offer some protection from power outages.
It depends on your location and the kind of panels you plan to use. With the winter months in Louisiana being very mild, you have significant leeway to install your panels, though they won't reach peak performance until summer arrives.
Yes, you can use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, so you can reap the savings and environmental benefits of solar energy without having to completely switch over.
Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Gretna, the average amount someone can save is $1,790 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system when your payback period is done.
While solar energy might not be the best performing choice for some in dark or wet areas, the latest generation of equipment and energy storage systems could boost your property's solar viability enough to achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.
Yes. Solar panels are independent of the Gretna grid and will continue to generate power even if the grid is having problems. Keep in mind, however, that a solar system without a storage system cannot keep you running through a nighttime outage. Your contractor can discuss some economical options to keep your home's power access reliable through the worst conditions, including battery backups or an emergency generator.
