Are Solar Panels Worth It in California?

Absolutely! Solar panels are a smart choice in California. Not only can they reduce your energy bills, but they also increase your property value and provide protection against rising energy costs.

With the state’s commitment to clean energy, going solar is both environmentally and financially beneficial.

  • Property Value Increase: Homes with solar panels often boost their property value, which makes them smart investments for the future. Compared to homes without solar panels, they sell for 4.1% more. In California, where the median home value is $676,000, a solar system can increase your home’s value by $27,716.
  • Energy Cost Protection: Solar panels can provide protection against rising energy costs, which are unpredictable and volatile. By generating your own power from the sun, you can reduce your dependence on the grid and avoid paying higher rates. With solar panels, you can lock in your electricity rate and save money in the long run.
  • Environmental Benefits: By going solar, you can reduce your carbon footprint and help California achieve its ambitious clean energy goals. Solar energy is a renewable and pollution-free source of power that does not contribute to climate change or harm wildlife.

Methodology

To assess the solar potential in California, we need to consider various factors that affect the feasibility and profitability of solar energy. These factors can be grouped into four main categories: solar resources, rooftop space, solar technology, and solar incentives.

Solar Resource

The solar resource is the amount of sunlight that reaches the state throughout the year, determining the potential electricity generation from solar panels. The solar resource can be measured by two indicators: the global horizontal irradiance (GHI) and the peak sun hours (PSH).

  • GHI is the total amount of solar radiation received on a horizontal surface per unit area per unit of time, expressed in watts per square meter (W/m2). The GHI varies depending on the location, season, time of day, and weather conditions. The higher the GHI, the more solar energy is available.
  • PSH is the equivalent number of hours per day when the solar irradiance is 1,000 W/m2, which is the standard condition for testing solar panels. The PSH accounts for the variations in the solar angle and the atmospheric attenuation throughout the day. Plus, the higher the PSH, the more effective the solar panels are.

Rooftop Space

The rooftop space is the availability and suitability of the roof area for solar panel installation. It determines the potential capacity and output of solar systems. The rooftop space can be measured by four factors: the roof area, tilt, azimuth, and shading.

  • The roof area is the total surface area of the roof that can accommodate solar panels. It considers structural integrity, building codes, fire safety, and aesthetic preferences. The larger the roof area, the more solar panels can be installed.
  • The roof tilt is the angle of the roof relative to the horizontal plane, which affects the orientation and exposure of the solar panels. The optimal roof tilt depends on the latitude and the season. That said, a tilt close to the latitude angle maximizes the annual solar production.
  • The roof azimuth is the direction that the roof faces, which affects the amount and timing of the solar irradiance received by the solar panels. The optimal roof azimuth depends on the hemisphere and the time of day. Generally, a south-facing roof (in the northern hemisphere) receives the most solar energy throughout the year.
  • The roof shading is the obstruction of solar irradiance by nearby objects, such as trees, buildings, chimneys, or power lines. The roof shading reduces the performance and lifespan of the solar panels. It should be minimized or avoided as much as possible.

Solar Technology

Solar technology is the cost and performance of different types of solar panels and systems, which determines the economic viability and environmental impact of solar energy. Solar technology can be measured by three factors: the price per watt, efficiency, and durability.

  • The price per watt reflects the upfront investment required to install a solar system, influencing the payback period and the return on investment. A lower price per watt means a more affordable solar setup.
  • The efficiency reflects the conversion rate of the solar panel and influences the electricity production and the space requirement. The higher the efficiency, the more productive the system.
  • The durability reflects the quality and reliability of the solar panel. It influences the maintenance, cost, and environmental benefit. Your solar setup may be more sustainable if it has longer durability.

There are different types of solar panels and systems available in the market, each with its own advantages and disadvantages. 

The most common types are:

  • Monocrystalline silicon (mono-Si) panels are made of single-crystal silicon cells that have a high efficiency (15-22%) and durability (25-30 years). However, they have a high price per watt ($0.8-1.2/W) and a high energy payback time (1.5-2.5 years).
  • Polycrystalline silicon (poly-Si) panels are made of multi-crystal silicon cells that have moderate efficiency (13-18%) and durability (20-25 years). That said, they usually also have a moderate price per watt ($0.6-0.8/W) and energy payback time (1-2 years).
  • Thin-film panels, which are made of thin layers of materials such as amorphous silicon (a-Si), cadmium telluride (CdTe), or copper indium gallium selenide (CIGS) that have low efficiency (7-13%) and durability (10-15 years). These panels have a low price per watt ($0.4-0.6/W) and payback time (0.5-1 year).

Solar Incentives

Solar incentives are policies that support solar adoption, such as the federal tax credit, state rebates, net metering, and feed-in tariffs. These incentives can reduce the cost and increase the revenue of solar systems, making them more attractive and competitive.

  • The federal tax credit allows you to deduct 26% of the cost of installing a solar system from your federal income taxes as long as the system is installed by year-end. It can significantly lower the upfront cost and the payback period of your solar setup.
  • The state rebates are cash incentives that are offered by some states, utilities, or local governments to consumers who install solar systems. For example, in California, the California Solar Initiative (CSI) provides rebates ranging from $0.2 to $1.1/W for residential and commercial solar systems [2].
  • Net metering can effectively reduce electricity bills and increase solar system savings.
  • The feed-in tariffs are payments that some utilities or governments make to consumers who generate electricity from renewable sources. The Renewable Market Adjusting Tariff (ReMAT) program in California pays up to $0.13/kWh for small-scale renewable generators [3].

Using solar calculators and simulators, consumers can estimate the electricity production, savings, and payback period of different solar systems. These tools consider your solar resources, rooftop space, solar technology, and solar incentives.
