Factors that Affect Solar Panel Costs in Union

The cost of installing a solar system in Union can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is the size of the system you need, and other factors include equipment choices, financing options and the solar installer you choose.

Solar Equipment

The size of the solar system you need for your household, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $2,720. The type of solar equipment you choose can increase or decrease your cost 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. However, higher efficiency could save you more in the long run on your energy bills. Additionally, extra products, like solar batteries, can bring your total well above the Union average.

Solar Financing Terms

If paying for a solar system out of pocket is out of reach, solar loans are a popular option because they reduce your upfront costs and let you pay for your system over a term of, on average, between five and seven years. 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 finding a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

The solar installer you choose to handle your switch to green energy can play a part in your total costs. There are about 3 solar panel companies in Union, and each can charge varying amounts for labor and equipment. Larger national companies usually have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since choosing a company can be a tough decision, we have some tips to help you, such as:

  • Reputation: Make sure your solar panel installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by past customers and solar experts like the EcoWatch team.
  • Contract: Before you sign a contract with a solar company, make sure you read it through completely so you understand the terms. Also, ask questions if you aren't sure about some of the terms, such as what to do if a component breaks or malfunctions and if there are any guarantees about energy production.
  • Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a large role in the company you choose.
  • Warranty: Warranties that cover panel repairs and maintenance over around 25 years are the best you can get in the business, and offering that kind of warranty is one sign of a quality company.
