Factors that Affect Solar Panel Costs in Lafayette
Cost is typically one of the most important factors for homeowners wanting to invest in solar. There are a few key factors that determine your overall cost in Lafayette: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.
Solar Equipment
The cost of solar panels 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 with better efficiency or power generation require 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 kind of solar panels and equipment you want is another factor that will considerably affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Further, solar equipment goes beyond just the solar panels themselves. You’ll also need to decide on 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 into a solar system that falls within your budget.
Solar Financing Terms
If paying for a solar system in cash is difficult, solar loans are a solid option because they cut back your upfront costs and let you pay for your system over five to seven years on average.Although solar loans make adopting solar energy more accessible for Lafayette homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
A final consideration when trying to evaluate the cost of solar for your home or business in Lafayette is the company you hire to install your solar panel system. Similar to choosing a company to install new cabinets, for instance, there’s no shortage of solar installers that provide a range of services at different costs.Larger national companies typically have lower costs, but some local companies compete with them by offering 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 vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
Since the type of solar panels and the installation company you choose has an impact on your costs and your system’s efficiency, production, and durability, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:
- Installation Process: Get detailed information from your solar installer about the installation process and what to expect, including when the site survey will be completed and what the project timeline is.
- Reputation: Your solar installer should have a solid reputation as a company and have verifiable expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from previous customers.
- Warranty: Warranties that cover panel repairs and maintenance over a long period of time such as 25 years are the gold standard in the business, and offering such a warranty is one mark of a quality company.
- Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. Even though there are many options for which type of solar panel you can get, not every company will have access to the exact one you may want or need, so be sure to ask for their list of options before making your decision.

EcoWatch's Lafayette, CA Solar Cost FAQs
What is the average cost of installing solar panels in Lafayette?
The average cost of solar panels in Lafayette is about $17,350 for a 5-kW system and $34,700 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the kind of solar panels you want, what size system you need and how much energy you consume.
What other factors should I consider aside from cost when buying solar panels?
Cost is certainly one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.
Can you sell solar power back to the grid in Lafayette?
Most states offer net metering programs of some kind. Through these, you can receive compensation for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.
What solar power system size is right for my home?
To figure out what solar panel system size you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
