Factors that Affect Solar Panel Costs in San Luis Obispo
For many San Luis Obispo homeowners, the decision to install a solar energy system comes down to cost. However, the range of solar installation costs can be quite wide in San Luis Obispo, with typical prices between $20,000 to $40,000. There are several factors that greatly influence the price you'll pay, which we'll go over below.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to spend around $2,730 per kilowatt in San Luis Obispo. There are many different solar panel brands and the one you pick also changes the cost. Generally, the brands that have better efficiency 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 much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Solar panels can save you money on utility bills over many years, but they can also be a significant investment. That's why many San Luis Obispo homeowners choose to finance their solar panel systems to make going solar more affordable. However, the interest on solar loans also adds to your overall costs, so it's crucial to take that into consideration as well. You can always bring down the total you pay in interest and sometimes even your APR by making a larger down payment.
Solar Panel Installation Company
A final consideration when trying to figure out the cost of solar for your home or business in San Luis Obispo is the company you choose to install your solar panel system. Similar to choosing a company to build a deck or pool, for instance, you'll have many options for solar installers that offer a range of services at different price points. 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 at a higher cost. It's best to do some research and find a company that offers the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels
There are numerous companies to choose from in San Luis Obispo, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be tough, so here are some tips to help you decide:
- Contract: It's important to read through your solar installer's contract closely to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to install your solar system. Another way you can verify your installer's reputation is by reading reviews.
- Solar Panel Brands: Each solar panel brand and type has varying levels of quality, durability and efficiency. They will come at different prices as well. The company you choose has an impact on which solar panel brands you have access to.
- Warranty: A high-quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
