How Many Solar Panels Do You Need in California?
Since our founding in 2009, our solar installers have been building, designing, and engineering large, advanced commercial solar systems. With our extensive background in the industry and the variety of technologies available, we’re proud to offer residential solar systems that blend energy efficiency, performance, and longevity with liveability and aesthetics.
Site Surveys
Before Westcoast Solar Energy installs or quotes a project, our solar installation team performs site surveys to:
- Measure the available space and the best layout for panels.
- Assess the home’s solar energy potential
- Evaluate the quality, strength, and remaining life of the roof
- Determine if the electrical system is safe to accommodate a solar installation
- Explain any federal or state tax credits and incentives available.
Our goal is to create quality, longevity-based solar installations that you can rely on for years to come. With technological advancements, government incentives, and growing demand, now is the time to go solar.
Determining How Many Solar Panels Are Needed
The number of solar panels that we have to utilize depends on the location, energy production capabilities, energy needs, and type of system.
Location
Homes in areas with fewer sunlight hours require more solar panels to eliminate electricity bills. While the location matters, the amount of sunlight your home gets could also be impacted by shade from overhanging trees, the angle of the roof, and pollution.
Energy Production Capabilities
Depending on the solar companies you are talking to, the number of solar panels they recommend can vary. This variation is due to the size and quality of the solar panels themselves. The wattage you go with determines how much energy it will produce and how many panels are needed. Some panels may have a low power rating of 150 watts, while others are higher at around 350 watts.
Energy Needs
The solar panel system must generate 100% of your home’s energy needs to eliminate energy bills. The amount of energy your home uses annually fluctuates based on the size of your home, number of residents, energy consumption habits, and energy efficiency of your home’s appliances.
Before calculating the estimated energy production your home requires, we also look into your future energy needs and whether that will impact the number of panels necessary. This includes:
- Are you planning on changing your HVAC unit?
- Will there be another member of the household?
- Do you plan on buying an electric vehicle?
Type of System
The number of solar panels required is more significant for those looking to gain energy independence with an off-grid system. Off-Grid systems also require solar batteries to store excess electricity for later use. With a grid-tied system, there is always the option of relying on the traditional energy grid if energy usage has increased for holidays or heat waves.
Are Solar Panels Worth It?
Homeowners who go solar enjoy lower energy bills and increased property values. While the initial investment into solar could deter some homeowners, with the savings on energy bills, most systems have a payback period of fewer than ten years. After this period, homeowners reap the benefits of clean, free electricity for years to come.
