Factors that Affect Solar Panel Costs in Gretna
There are several factors that can play into your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.
Solar Equipment
The size of the solar energy system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $3,800. The type of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for 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, more efficient panels could save you more in the long run on your electric bills. Additionally, extra products, such as solar batteries, can bump up your total well above the Gretna average.
Solar Financing Terms
If paying for solar panels out of pocket is difficult, solar loans are a popular route because they lower your upfront costs and let you pay for your system over a term of, on average, between five and seven years.When considering your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.
Solar Panel Installation Company
Finally, the company you get to install your solar system can play a role in determining your pricing. Gretna’s solar companies all have different labor costs and add varying upcharges to equipment. Some companies only sell high-quality, high-efficiency and high-price 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 decide on the company that has the products, warranties and services you want and also fits within your budget.
