Factors that Affect Solar Panel Costs in McKinney
The cost of installing a solar system in McKinney can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The most significant one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power production need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $3,330.The brand of solar panels and equipment you want is another factor that will largely affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Plus, solar equipment consists of more than just the solar panels themselves. You’ll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking for a solar system that’s in your budget.
Solar Financing Terms
If paying for solar panels in cash is out of reach, solar loans are an affordable choice because they cut back your upfront costs and allow you to pay for your system over five to seven years on average.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low APR could reduce your costs significantly.
Solar Panel Installation Company
Finally, the company you get to install your solar system can affect how much you pay. McKinney’s solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in McKinney know more about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.
