What Is the Cost of Solar Power Per kWh in California?

California is one of the leading states for solar energy adoption, and for good reason. With abundant sunshine and strong incentives, homeowners and businesses alike are turning to solar to save on electricity costs. One of the key factors in determining how much you’ll save with solar is understanding the cost per kilowatt-hour (kWh). So, what is the solar cost per kWh in California, and how does it compare to the cost of traditional electricity? Let’s dive in and explore everything you need to know.

What Is the Cost of Solar Power Per kWh in California?

The cost of solar power per kWh in California can vary depending on several factors, such as the size of your solar system, the type of panels you use, and whether or not you take advantage of state and federal incentives. On average, the cost of solar energy per kWh in California is between $0.07 and $0.12 per kWh. This is significantly lower than the average retail electricity rate in the state, which is around $0.24 per kWh.

This difference means that by installing solar, you can cut your electricity bill by more than half. In fact, many Californians are seeing savings of thousands of dollars over the lifetime of their solar panels.

Factors That Affect Solar Cost Per kWh in California

Several factors can affect the exact solar cost per kWh for your home or business:

  1. Size of the Solar System
    Larger systems typically cost less per kWh because the upfront installation costs are spread over more energy production. For example, a 5kW system will generally have a higher cost per kWh than a 10kW system, even though the 10kW system has a larger upfront cost. The larger system will produce more energy, driving down the cost per unit of electricity.
  2. Solar Panel Efficiency
    The efficiency of your solar panels also plays a significant role in determining the cost per kWh. High-efficiency panels may cost more upfront, but they produce more electricity from the same amount of sunlight, lowering the overall cost per kWh.
  3. Location
    California’s sunny climate is a major advantage, but even within the state, your exact location can affect the cost per kWh. If you live in Southern California, you might generate more solar power than someone in Northern California due to differences in sunlight exposure.
  4. Incentives and Rebates
    State and federal incentives can significantly lower the cost of your solar installation. In California, incentives like the California Solar Initiative (CSI) and the Federal Investment Tax Credit (ITC) can reduce the cost of solar by 30% or more, lowering your overall cost per kWh.
  5. Net Metering
    Net metering allows you to sell excess solar energy back to the grid, further reducing your cost per kWh. With net metering, your utility company credits you for the excess energy your panels produce, which can offset the energy you use when your panels aren’t producing enough (like at night).

How Much Does Solar Installation Cost in California?

The average cost of installing solar in California varies based on the size of the system. Generally, you can expect to pay between $15,000 to $30,000 for a residential system. After federal tax credits, the cost can drop to between $10,500 and $21,000.

  • A typical 6kW system, for example, costs about $18,000 before incentives and around $12,600 after applying the federal tax credit.
  • Larger systems, such as a 10kW system, can cost about $30,000 before incentives and $21,000 after.

When you break down the cost over 20 to 25 years (the typical lifespan of solar panels), the per kWh cost is much lower than traditional electricity rates in California. This makes solar an extremely cost-effective solution, especially for long-term savings.

How Solar Saves You Money in California

Going solar in California can save you a significant amount of money, especially as electricity rates continue to rise. The California Public Utilities Commission (CPUC) has reported that residential electricity rates in California have increased by about 6% annually over the past decade. This means that without solar, your electricity bill will only get higher.

Here are a few ways that solar saves you money:

1. Lower Electricity Bills

By generating your own electricity, you’ll rely less on your utility company. Depending on the size of your system, you may even be able to eliminate your electricity bill entirely. This is especially true if you use net metering to sell excess energy back to the grid.

2. Protection Against Rising Energy Costs

With solar, you lock in your electricity rate at the cost of your solar panels. As mentioned earlier, the cost of solar per kWh is much lower than the cost of grid electricity in California. By going solar, you protect yourself from future rate hikes and ensure long-term savings.

3. Tax Credits and Rebates

The Federal Solar Investment Tax Credit (ITC) allows you to deduct 30% of the cost of your solar system from your federal taxes. In addition to federal incentives, California offers several rebates and local programs to help offset the cost of solar installation. These incentives can significantly reduce your upfront costs and shorten the payback period for your solar investment.

4. Increased Home Value

Installing solar panels can increase the value of your home. In California, homes with solar systems tend to sell for more than homes without. This means that in addition to the savings on your energy bills, you’ll also see a return on your investment when it’s time to sell your home.

5. Environmental Benefits

While not a direct monetary saving, solar energy reduces your carbon footprint and helps combat climate change. California is committed to reducing greenhouse gas emissions, and by going solar, you’re contributing to a cleaner environment. According to Energy.gov, the average solar home in California can offset more than 100,000 pounds of CO2 over the lifetime of the system.

Solar vs. Traditional Electricity in California

One of the most compelling reasons to switch to solar is the comparison between the cost of solar energy and traditional electricity. As of 2023, California’s average residential electricity rate is $0.24 per kWh, one of the highest in the nation. By contrast, the average solar cost per kWh is much lower, typically ranging between $0.07 and $0.12 per kWh after incentives.

Here’s a quick comparison:

  • Traditional electricity cost: $0.24 per kWh
  • Solar cost: $0.07 to $0.12 per kWh after incentives

As utility rates continue to rise, the cost of solar remains stable, making it a more attractive option for long-term savings.

How to Calculate Your Solar Cost Per kWh

To calculate your solar cost per kWh, you’ll need to know the total cost of your solar system and the amount of electricity it will produce over its lifetime. Here’s a simple formula to help:

  1. Calculate Total System Cost:
    Let’s assume your system costs $20,000 after incentives.
  2. Estimate Total Electricity Production:
    Solar panels typically last 25 years. If your system generates 8,000 kWh per year, that’s 200,000 kWh over the system’s lifetime.
  3. Divide the Total Cost by Total Electricity Production:
    $20,000 / 200,000 kWh = $0.10 per kWh.

In this example, your solar system would cost you $0.10 per kWh over its lifetime, significantly less than the current cost of electricity in California.
