Factors that Affect Solar Panel Costs in San Luis

There are a number of factors that can determine your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. Because of that, it’s a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your energy needs.There are several different solar panel brands and the one you choose also changes the cost. In many cases, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be far 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 San Luis to be prohibitively steep, even if the investment pays off over time. Fortunately, almost every solar company in the area offers financing options. Solar loans remarkably decrease upfront costs in most cases, but they also result in paying more over time because of interest.It’s wise to factor 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 how long it’ll take to pay back the loan.

Solar Panel Installation Company

The solar company you pick will play a role in your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor.Companies that only sell products with high efficiency and therefore a higher price point — 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 go with the company that provides the products, warranties and services you’re looking for and also fits within your budget.
