Factors that Affect Solar Panel Costs in Gretna
Cost is usually one of the most important factors for homeowners considering investing in solar. There are a few major factors that affect your total cost in Gretna: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. Because of that, it's important to accurately gauge the size of the solar energy system needed for your home by figuring out your typical energy use. The brand and type of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in Gretna to be too steep, even if the investment pays off over time. Thankfully, nearly every solar company in the area offers financing options. Solar loans substantially decrease upfront costs for most homeowners, but they also lead to paying more over time because of interest. However, the interest on solar loans also increases your total costs, so it's vital to include that in your estimate as well. You can always bring down the total you pay in interest and possibly even your APR by making a larger down payment.
Solar Panel Installation Company
The solar installation company you pick will influence your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor. Some companies only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It's best to do some research and choose a company that provides the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels
There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you pick the right company for you, here are some tips to keep in mind:
- Installation Process: Make sure you're aligned with the installer regarding how the installation process will go and what you need to do before your solar panels are installed, such as updating or replacing your electrical system or roof.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. Although there are many options for which type of solar panel you can get, not every company will have access to the exact one you may want or need, so be sure to ask for their list of offerings before deciding.
- Warranty: A high-quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Contract: Before signing a contract with a solar installer, be sure to read it through carefully so you understand the terms. Also, ask questions if you're not sure about some of the terms, such as what the warranty covers and what services you can expect from them.

EcoWatch's Gretna, LA Solar Cost FAQs
How much does it cost to install solar panels in Gretna?
This is a difficult question to answer exactly, because the cost depends on a variety of factors. Broadly speaking, it costs about $12,850 for a 5-kW system and $25,700 for a 10-kW system after the ITC is applied. It will cost more if you want other solar equipment or higher quality panels, or if you have higher-than-average energy needs. On the flip side, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.
Is cost the most important thing to consider when buying solar panels?
Cost is without a doubt one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.
Does Gretna have a net metering program?
Most states offer net metering programs of some kind. Through these, you can either get paid for the extra power your system generates or or receive credits to put toward future energy bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.
How many solar panels should I get to power my home?
To figure out how many solar panels you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
