Factors that Affect Solar Panel Costs in Gretna

Cost is typically one of the most important factors for homeowners who want to invest 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

The size of the solar panel system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $2,570. The type of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your electric bills. In addition, add-on products, like solar batteries, can bring your total well above the Gretna average.

Solar Financing Terms

Most solar installers in Gretna provide solar loans, which reduce the initial cost of installing solar panels. When considering your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more upfront can lower the total interest paid over time.

Solar Panel Installation Company

Finally, the company you hire to install your solar panel system can affect how much you pay. Gretna's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Gretna have more knowledge about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

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.
