Factors that Affect Solar Panel Costs in Larkspur
The cost of installing a solar system in Larkspur can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The most significant one is the size of the system your home needs, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater 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.There are a lot of different solar panel brands and the one you pick also affects the cost. Typically, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you want to install can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
If paying for a solar system in cash is out of reach, solar loans are a popular route because they lower your upfront costs and let you pay for your system over five to seven years on average.It’s wise to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it’ll take to pay off the loan.
Solar Panel Installation Company
The solar installer you opt for to handle your switch to sustainable energy can play a part in your total costs. There are about 3 solar installation companies in Larkspur, and each can charge different amounts for labor and equipment.Additionally, some companies in Larkspur have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels
The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since picking a company can be a challenge, we have some tips to help you, such as:
- Contract: When reading through your solar installer’s contract, ask questions about any terms you’re not sure of and be sure you understand what happens in scenarios such as a system part breaking or the company going out of business.
- Reputation: Your solar installer should have a solid reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has satisfied reviews from previous customers.
- Solar Panel Brands: Each solar panel brand and type has varying levels of quality, longevity and efficiency. They will come at different price points as well. The company you choose has an impact on which solar panel brands you have access to.
- Installation Process: Get details from your solar company about the installation process and what to expect, including when the site survey will be completed and what the project timeline is.

What other factors should I consider aside from cost when buying solar panels?
The initial cost is a crucial factor to consider, but whether it’s the most important for you depends on your goals for going solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to consider are the quality and durability of your solar panels.
How much can I save on power bills after switching to solar?

How often do you have to replace solar panels?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency.
