Factors that Affect Solar Panel Costs in Marrero
Cost is usually one of the most important factors for homeowners considering investing in solar. There are a few primary factors that affect your total cost in Marrero: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.
Solar Equipment
The size of the solar energy system you need to offset your energy usage, 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 $3,800. The kind of solar equipment you choose can bring your price up or down 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. However, more efficient panels could save you more over time on your energy bills. Additionally, extra products, like solar batteries, can bring your total well above the Marrero average.
Solar Financing Terms
Most solar installers in Marrero provide solar loans, which reduce the initial cost of installing solar.It’s a good idea to include the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it’ll take to pay off the loan.
Solar Panel Installation Company
Finally, the company you get to install your solar panels can play a role in determining how much you pay. Marrero’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies typically have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels
The solar panel company you opt for will influence not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are several important things you should consider, such as:
- Warranty: Each company may offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.

- Contract: Although reading through a contract can be tedious, it’s important to do it carefully so you can be sure you understand what services your solar company will provide and the terms of the warranty.
