How many solar panels do I need to offset my PG&E bill?

One of the primary reasons people install solar panels is to save money. More specifically, people are looking to off-set their monthly PG&E bill. 

Wondering how many solar panels you need to do that? With differing levels of energy consumption, direct sunlight availability, and physical structure needs, that answer looks different for every household or business. But as your local solar experts, A.M. Sun Solar will assess your specific energy needs and identify your goals so that we can work to create a customized solar plan that works for you! 

There are several factors that we take into consideration when determining your custom solar solution. When we calculate how much solar energy you will need to reach your goals, we take into account 3 key factors: 

1. How much energy you currently use

Your average daily energy usage is the main measurement used to calculate your solar needs. This is the number of kilowatt-hours you need your solar system to produce in order to cover your electricity needs, and it’s the first metric we’ll look at when determining what type and how many panels you’ll require. 

To find this information, go to the customer portal on the PG&E website. Navigate to your “Energy Usage Details” and view your weekly energy usage in kwh. Take a screenshot of the graph that you see and have it handy to show or share with one of our experts. 

At A.M. Sun Solar, we recommend adding a 25% cushion to your daily average energy usage to ensure you can generate enough clean solar energy to offset your entire yearly energy consumption.

2. The amount of sun exposure your home or business gets throughout the day

The peak sunlight hours at your home or business have a direct impact on the amount of energy you can expect your home solar system to produce. For example, if you live in a sunnier area of the Central Coast, you can expect to have a greater number of peak sunlight hours than if you lived in a more foggy or heavily shaded area. Keep in mind that this does not mean that a home in a coastal or forested area can’t go solar, it simply means that customers in areas as such will need more panels to offset their PG&E bill.

3. Which type of solar equipment will best meet your needs and ensure maximum efficiency of your system

Because of the wide variation in quality and efficiency of solar panels, there is no “one-size-fits-all” solution when it comes to solar. Instead, one of our experts will take into account your energy needs, amount of sunlight your house or business gets, the physical size of the solar panels you will need based on your roof type and structure, budget, and several other factors to recommend the best solar product for you.

One thing our experts keep top of mind when recommending a product to you is the quality of the solar panels. This makes a big difference in your system’s performance! The more efficient the panels are, the more wattage they can produce, and the fewer panels you will need to place on your roof to garner the same energy output. 

All things considered, we ensure that we maximize the overall efficiency of your custom solar energy system every step of the way. This means: 

  • Assessing what wattage is most appropriate for your energy consumption. At A.M. Sun Solar, Photovoltaic (PV) solar panels come in wattages ranging from about 325 -460 watts per panel. 
  • Identifying the optimal panel size and cell technologies to fit your structural needs and energy goals. 
  • Calculating how many panels are necessary for your home while optimizing efficiency by making the appropriate decisions around conversion points and microinverters

At A.M. Sun Solar, we work with a local San Luis Obispo county distribution center to source almost any type of preferred panel or solar system equipment within reason. We’re confident that we will find the right system for you!
