Factors that Affect Solar Panel Costs in Eureka
There are many criteria that can affect your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
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 with better efficiency or power generation use 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 $3,470.Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Eureka, where sunlight is abundant, efficiency can quickly pay off. In addition, if you have a small roof or limited space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
If paying for a solar system out of pocket is out of reach, solar loans are an affordable route because they lower your upfront costs and let you pay for your system over a term of, on average, between five and seven years.However, the interest on solar loans also adds to your total costs, so it’s crucial to keep that in mind as well. You can always reduce the total you pay in interest and in some cases even your APR by putting more money down.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Eureka is the company you choose to install your solar panel system. Similar to choosing a company to install new cabinets, for instance, you’ll have no shortage of solar installers that provide a range of services at different price points.You may come across national solar installers that have lower prices due to their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

- Reputation: Make sure your solar installer has a good reputation by confirming it has certifications and licenses, checking how long it's been in business and reading reviews by past customers and solar experts like the EcoWatch team.
- Warranty: Warranties that provide coverage for defective panels and repairs over a couple decades are the gold standard in the business, and offering such a warranty is one sign of a good company.
- Solar Panel Brands: The kind of solar panel you need plays a part in which installer you should choose, since different companies provide different panels.
- Contract: Before you sign a contract with a solar company, be sure to 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 part breaks or malfunctions and if there are any guarantees about energy production.
