Is 10 kW Solar Enough?


Installing a solar panel system has become an increasingly attractive option for homeowners looking to reduce their energy bills and make their homes more sustainable. When choosing a system, the size of the system — measured in kW — is an important factor to consider. The question of whether a 10 kW solar system is enough for an average American household depends on a number of factors, such as the size of the home and the amount of electricity used. In this article, we’ll discuss the average American energy usage, state-specific energy consumption, and the pros and cons of a 10 kW solar system.

Average Energy Usage

The U.S. Energy Information Administration (EIA) estimates that the average American household consumes about 11,000 kWh each year. This figure is generally consistent throughout the country, but may vary depending on the size and age of the home, as well as local climate conditions.

To determine how much energy usage is right for your home, the first step is to calculate your energy usage. There are a number of tools available to help with this. Most utility companies can provide you with monthly energy usage data. You can also use an energy calculator or install a whole-home energy usage monitoring system to view your usage over time.

State Specifics

The amount of energy consumed by an average American home may vary widely depending on the state. According to the EIA, the states with the highest energy usage in 2018 were Alaska (16,182 kWh), Louisiana (14,568 kWh), and Arkansas (14,404 kWh). Meanwhile, the states with the lowest energy usage were Arizona (7,583 kWh), Hawaii (7,470 kWh), and California (7,096 kWh).

Pros and Cons of 10 kW Solar

A 10 kW solar system can provide enough electricity to cover the energy needs of an average American household, which typically consume 11,000 kWh per year. The system can be installed either on the roof or on the ground, and its size will depend on the amount of roof space or availability of ground space. It is typically composed of 40 to 50 solar panels, and may require additional equipment such as an inverter and batteries.

A 10 kW system allows for higher efficiency and requires less maintenance than a smaller system, such as a 5 kW system. Additionally, it allows for more potential future expansion. On the other hand, the initial cost of a 10 kW solar system is roughly twice as expensive as a 5 kW system, so you need to carefully weigh the pros and cons before investing.


The answer to the question of whether 10 kW Solar is enough depends on the size and typical energy usage of an individual’s household. In most cases, it is more than sufficient and can comfortably generate the 11,000 kWh of energy needed to power an average American home. However, households in states with higher energy usage should take this into consideration when choosing a solar system. Additionally, those with specific energy needs may find that larger systems or additional energy-saving measures are needed.
