Factors that Affect Solar Panel Costs in Diamond Bar
The cost of installing a solar system in Diamond Bar can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The biggest one is your system size, and other factors include equipment choices, financing options and the solar company you choose.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power generation need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,470.The 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 in the long run on your electric bills. In addition, extra products, like solar batteries, can bring your total well above the Diamond Bar average.
Solar Financing Terms
If paying for solar panels out of pocket is too expensive, solar loans are a popular option because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.However, the interest on solar loans also increases your overall costs, so it’s important to consider that as well. You can always bring down the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
The final major cost factor you should take into consideration is the installer you choose. Given the massive popularity of sustainable energy solutions in Diamond Bar, you’ll have a great number of options to choose from, but each comes at varying price points for labor and equipment.You may see national solar installers that have lower prices due to their bigger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.
