Factors that Affect Solar Panel Costs in St. Rose

Even though the average cost of a solar system in St. Rose is $26,366, your final cost may be higher or lower than that. There are quite a few factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more crucial things to consider.

Solar Equipment

The size of the solar energy system you need for your household, 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 around $3,800. There are several different solar panel brands and the one you choose also affects the cost. In many cases, the brands that offer higher efficiency tend to also cost more. Additionally, the type of equipment you choose can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Many homeowners find the average cost of solar in St. Rose to be too steep, even if the investment pays off over time. Fortunately, nearly every solar company in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to a higher cost over time due to interest.Though solar loans make going solar more accessible for St. Rose homeowners, they can also increase the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

A final consideration when trying to figure out the cost of solar for your home or business in St. Rose is the company you hire to install your solar panel system. Similar to choosing a company to install new cabinets, for example, there are plenty of solar installers that offer a range of services at different costs.You may see national solar installers that have lower prices because of their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or specials to compete with those major players.
