Now is a great time to think about adding solar panels to your home, as installation costs are decreasing. You can determine the cost of solar panels for 3 bedroom house here. You can also learn more about solar power for homes and the average cost of residential solar panels. 

This article will discuss the cost of installing solar panels. Also included are the factors that affect their price and how to install them. Additionally, it will discuss the amount of money you can save by switching to solar energy.

What is the Cost of Solar Panels for 3 Bedroom House in California?

Cost Of Solar Panels For 3 Bedroom House in California

Installing solar panels on a standard three-bedroom home in California, typically spanning 2,000 square feet, can cost between $15,000 and $40,000. However, the actual system cost may vary significantly depending on several key factors, including:

  • Your home’s average energy usage and utility bills
  • The amount of sunlight your rooftop receives
  • The going rate for solar panel installation in your area
  • Labor costs in your region
  • Available local incentives and rebates for solar panel adoption

As solar technology gets better and more people want it, the cost of installing solar panels is going down. This makes it a better choice for homeowners.

Solar Panels for a 3-Bedroom House vs. a 4-Bedroom House

The cost of home solar panel system depends on its size. For a 3 bedroom house, the cost is between $15,000 and $40,000. For a 4-bedroom house, the cost is higher, ranging from $8,500 to $30,500. This is because bigger houses need more solar panels to generate enough energy.

While the cost may seem high, solar panels can save you money on energy bills and help the environment. It’s a good investment for your future.

How Many Solar Panels Will You Need?

To determine the number of panels needed for your home, first calculate your energy consumption. Next, consider the type of panels you intend to install. The average American household uses approximately 900 kilowatt-hours of electricity monthly, which translates to around 11,000 kilowatt-hours annually. Reviewing your past utility bills will help you calculate your exact energy usage.

A 3-kilowatt solar panel system typically generates between 3,600 and 4,800 kilowatt-hours of electricity per year. A 5-kilowatt system can produce between 6,000 and 8,000 kilowatt-hours per year. A 10-kilowatt system can generate between 12,000 and 16,000 kilowatt-hours annually.

The cost of solar panels ranges from $4,000 to $16,000, depending on the system’s size. You will also need to budget $3,000 to $10,000 for necessary parts like panel mounts, wiring, and solar inverters. This brings the total cost of installation to about $20,000.

Factors Affecting the Cost of Solar Panels

The cost of solar panels can vary based on several factors. Here’s what you need to know:

Type of Panels

Solar panels come in different types, each affecting their cost. Monocrystalline solar panels are generally more expensive due to their higher efficiency rates and longer lifespan. Conversely, while polycrystalline solar panels are less expensive, they offer reduced efficiency.

Thin-film panels are versatile and lightweight, but they may not work as well in low-light conditions as crystalline panels. The type of panel selected significantly influences the initial capital needed for a three-bedroom home.

Homeowners should assess how much energy they use and how much roof space they have before choosing the right solar panels. The type of panel chosen will impact the initial cost and potential savings on energy bills in the long run. Local California solar incentives and federal solar tax credits can lower costs for certain solar panels, making them more financially appealing based on location.

Solar Panel Manufacturer

Various solar panel producers provide panels at diverse costs with a warranty of 25 years. High-quality monocrystalline solar panels, recognized for their superior efficiency, typically range from $1 to $1.50 per watt in price. Consequently, a single 400-watt panel from a leading manufacturer could be priced anywhere between $400 and $600.

Selecting the appropriate manufacturer can greatly influence the total expenses and the performance of your solar energy system. Different brands offer varying technology, warranty durations, and customer support. It’s crucial to conduct thorough research and identify a manufacturer that aligns with your financial capacity and energy requirements effectively.


Solar panel performance heavily depends on how efficiently they convert sunlight into electricity. Panels with higher efficiency require less space on your roof to meet energy needs, which also impacts cost. Panels of monocrystalline type, recognized for their superior efficiency, could cost anywhere from $1 to $1.50 per watt.

A solar panel’s efficiency is influenced by numerous elements, such as the materials utilized and the manufacturing process. Efficient solar panels generate more energy in a smaller area. This makes them ideal for homes with limited roof space. They are also perfect for households requiring a high amount of power without covering the entire roof.

Roof Pitch

The angle of your roof is important for installing solar panels. The best angle depends on where you live, how much energy you use, and what you like. Installing solar with the right angle can enhance sunlight absorption, thereby increasing power production. Experts consider your home’s specifics to find the perfect pitch, ensuring maximum efficiency from your solar system.

Location and Amount of Sunlight

Homes in sunny areas receive more energy from solar panels because of the abundance of direct sunlight. This allows them to generate more electricity without incurring additional costs.

Weather and local climate also play significant roles, with clear skies allowing more sun to hit the panels. The efficiency of solar panels is influenced by the position of your home. Roofs that get a lot of sun and have few obstructions typically produce more power.

Local Incentives

Some states give benefits for solar energy, like tax breaks or discounts, making it cheaper to buy and set up panels. Applying for these benefits can reduce costs, making solar energy more affordable.

The solar tax credit lets homeowners lower their federal taxes by 30% of the cost of buying and installing solar panels. This means that if you install solar panels, you can deduct 30% of the total cost from your federal tax bill.

The credit applies to both the purchase price and installation costs of the solar panels. We designed this incentive to encourage more people to invest in solar energy for their homes. Local governments can offer incentives such as tax breaks or loans to motivate homeowners to invest in solar energy. This helps to make solar energy more affordable for homeowners.
