9.2kW Solar System: Price, Load Capacity, How Big, and More

How Much Will a 9.2kW Solar System Save?

Investing in a solar system can lead to significant savings on your electricity bills over time. A 9.2kW solar system can save you up to $2,854 per year. Over the estimated 25-year panel lifetime, this can amount to a total saving of $71,358.

Rising Cost of Electricity

The cost of electricity has been on the rise over the past few decades. According to the U.S. Bureau of Labor Statistics, there has been an increase of 270% in electricity costs over the past 40 years. This upward trend makes solar energy an even more attractive option for those looking to reduce their reliance on traditional electricity sources.

Electricity Saving

One of the main advantages of installing a solar system is the ability to generate your own electricity. By producing your own energy, you can significantly reduce your reliance on the grid and the utility companies. The more self-generated electricity you consume, the less you will need to pay to the utility companies.

Solar Energy for a Profit

In addition to saving on your electricity bills, a solar system can also generate income for you. Any surplus electricity that you generate and do not use can be sold back to the grid. This means that you can earn money for the electricity you produce but don’t consume. With the current electricity costs, you can expect a return on your investment of around 20% per year on your panels.

9.2kW Solar Panel System Price

The typical cost for a 9.2kW solar system is approximately $18,400. However, it’s important to note that prices have come down substantially over the past 10 years. This decrease in cost has made solar systems more accessible to a wider range of consumers.

9.2kW System with Battery Backup

When considering a 9.2kW solar system, you may also want to include a battery backup. The choice of battery type is crucial, and it’s recommended to use lithium polymer batteries. With lead acid batteries, you would need a sizing of 9.2kWh x 2 (for 50% depth of discharge) x 1.2 (inefficiency factor), which equals 110 kWh. In contrast, with lithium batteries, you would need a sizing of 9.2kWh x 1.2 (for 80% depth of discharge) x 1.05 (inefficiency factor), resulting in 58 kWh. Choosing lithium batteries can significantly reduce the number of batteries needed, making them a more efficient and cost-effective option. It’s also worth considering purchasing the batteries and panels together to reduce overall costs.

9.2kW Off-Grid Solar System

If you’re looking to go completely off-grid with your solar system, a 9.2kW system requires careful planning. For this size, you would typically need 31 or more panels. Additionally, you would need 58 kWh worth of lithium polymer batteries to support a full cycle of energy consumption. The typical cost of the batteries required to run a 9.2kW off-grid system is approximately $27,241.

How Many Panels Are Needed?

Most solar panels have a capacity of 300 watts. To achieve a 9.2kW solar system, you would need 31 or more panels. Each panel typically has a size of 17 square feet, so the total footprint of a 9.2kW solar system would be around 521 square feet.

How Big is a 9.2 kW Solar System?

In terms of physical size, a 9.2kW solar system requires a significant amount of space. With each panel occupying 17 square feet and a total of 31 panels needed, the system’s total footprint comes to 521 square feet. It’s important to consider available roof or ground space when planning for your solar installation.

How Many kWh Does a 9.2kW Solar System Produce? (Load Per Day)

On average, a 9.2kW solar system produces around 46 kWh of electricity per day. This estimation is based on the panels receiving at least 5 hours of direct sunlight. In a month, this translates to approximately 1380 kWh, and over a year, it amounts to 16790 kWh.

How Many Batteries Needed For a 9.2kW Solar Panel System?

The number of batteries needed for a 9.2kW solar panel system depends on the battery type, specifically lead acid vs. lithium. If you opt for the recommended lithium polymer batteries, you would need 58 kWh worth of batteries. It’s worth noting that you have the option to purchase a single battery system or wire several smaller batteries together to meet your energy storage needs.

Is a 9.2kW Solar System Worth It?

Considering the potential savings and returns, a 9.2kW solar system can be a worthwhile investment. With an average of $2,854 worth of electricity generated per year, you can expect a 20% return on your investment based on the current costs of panels (approximately $18,400 for this system). Overall, a 9.2kW solar system offers significant financial benefits and is an excellent choice for those living in areas with ample sunlight.
