Factors that Affect Solar Panel Costs in Wonder Lake
The cost of installing a solar system in Wonder Lake can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is the size of the system your home needs, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
The size of the solar panel 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 nearly $3,760. 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 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 energy bills. In addition, add-on products, such as solar batteries, can bump up your total well above the Wonder Lake average.
Solar Financing Terms
Most solar installers in Wonder Lake provide solar loans, which reduce the initial cost of installing solar.Although solar loans make switching to solar energy more accessible for Wonder Lake homeowners, they can also increase the total you pay for your system due to interest. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar company you hire to handle your switch to green energy can play a part in your total costs. There are about 3 solar panel companies operating throughout Wonder Lake, and each can charge different amounts for labor and equipment.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 decide on the company that has the products, warranties and services you want and also fit into your budget.
