Factors that Affect Solar Panel Costs in Sonoma
Cost is often one of the most important factors for homeowners considering investing in solar. There are a few major factors that determine your overall cost in Sonoma: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. For that reason, it's crucial to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs. The kind of solar panels and equipment you get is another factor that will considerably affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Furthermore, solar equipment is more than 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 researching a solar system that falls within your budget.
Solar Financing Terms
If paying for a solar system in cash is out of reach, solar loans are a popular choice because they reduce your upfront costs and let you pay for your system over five to seven years on average. It's wise to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay back the loan.
Solar Panel Installation Company
Lastly, the company you opt for to install your solar panels can play a part in determining how much you pay. Sonoma's solar companies all have different labor costs and add varying upcharges to equipment. Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It's best to do some research and decide on the company that has the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels
Since the type of solar panels and the installer you choose greatly impacts your costs and your system's durability and efficiency, it's important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:
- Solar Panel Brands: Different companies have various brands and models of panels. If you know you want a specific brand, make sure the solar panel company you're considering has it.
- Contract: It's important to look over your solar installer's contract well to understand what services they will provide, what the warranty covers and what expectations you should have about the installation process.
- Warranty: A high-quality company stands out from other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Reputation: Long-running companies likely have a high reputation. This is important because it ensures that it will not only see your solar project through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.
