10kW Solar Systems Ideal for Every Budget

If you live in a spacious home and want to control your power expenses, it is the perfect time to buy a solar PV system. Many solar consumers who consider the 10kw solar system for their residences get anxious about its suitability. The good news is that this blog will proffer valuable and practical insights about every aspect of the 10kw solar panel system and will assist new solar users in making educated and profitable decisions regarding suitable solar PV systems. So, let’s dive in!

Size of A 10kw Solar Panel System

In most cases, a 10kW solar system utilizes an inverter with an 8kW maximum output capacity and is equipped with a sufficient number of panels to produce approximately 10.6kW of electricity.

As a rule of thumb, each individual panel typically carries a rating of approximately 330W. Consequently, the total number of panels in the system amounts to 32, resulting in a combined capacity of 10,600W or 10.6kW.


Inverter Size

Numerous solar users think that the inverter’s 8kW rating is smaller than the collective power of all the panels combined, and this could potentially lead to the inverter malfunctioning or “blowing up.” These are indeed important questions, and the answer is quite simple: no, it’s not a cause for concern.

In practice, solar panels rarely operate under ideal conditions where they can produce their maximum electricity output. Several factors contribute to a less-than-ideal environment, including the angle of installation, shading, weather conditions, sun orientation, cloud cover, humidity, and temperature fluctuations. As a result, solar panels will seldom operate at their maximum capacity.


How Does the 10KW System Ideal for Moderate Size Homes?

If you have a budget for a solar system of any size, it is best to select one that provides the maximum benefits without any undue excess. Before making a decision on a 10kW system, it’s essential to consider the following factors:

Power Consumption

A 10kW solar system generates an estimated daily 25kWh of electricity. If a household’s electricity consumption falls significantly below this figure, opting for a smaller solar system, like a 6kW system, might be more cost-effective for solar users.

In the case where electricity usage falls within the range of 15kWh to 25kWh, a 10kW solar system could be an ideal choice. However, if a consumer’s electricity consumption exceeds 25kWh, a larger system, like a 13kW system, for better coverage. To determine exact electricity consumption, solar users can refer to their grid power utility bill to get better insights into their usage patterns both monthly and annually.


Every home has its specific budget and power requirements, and to cater to every type of user, many states offer diverse solar rebates. A rough estimate to keep in mind is that the total installation cost, which includes the inverter, typically averages around $1 per watt. Therefore, for a 6kW system, solar consumers can expect the cost to fall within the range of $8,000 to $12,000.

Roof Space

Even if all the considerations mentioned above point towards the necessity of a 10kW system or a larger one, the available roof space on a solar user home plays a crucial role in determining whether it can accommodate the system.

Each solar panel measures about 1762mm x 994mm, which is roughly equivalent to 1.75m². To install a system with 32 panels, the user’s roof should have a minimum area of at least 55m². Also, setting solar panels facing north to have minimal shading from nearby trees or obstructions is significant for getting solar power for longer hours.

How Much Solar Consumer Can Save With a 10kW Solar System?

A moderate household consumes approximately 15 to 25kWh daily and would get an electricity bill of approximately $2,181 without a solar PV system. If grid power users opt for solar energy solutions, they can reduce their electricity bills by approx. $2,752 annually, while also earning approximately $570 per year through surplus electricity sold back to the grid.

The following table provides estimates of energy consumption, electricity costs, and potential savings for various household profiles.

Household Type Daily Power Usage Annual Electricity Bill Without Solar Annual Electricity Bill With Solar Savings
Low Energy-Consuming Household Less than 15kWh $1,655 -$1,018 $2,672
Medium Energy-Consuming Household 15kWh – 25kWh $2,181 -$570 $2,752
High Energy-Consuming Household More than 25kWh $2,708 $92



The bottom Line

A 10kW solar system is an excellent choice for homeowners seeking energy cost control. It offers efficient power generation with clean power. With a 10kW system, moderate to high energy-consuming households can save substantial amounts annually, even earning from surplus electricity sales through feed-in tariffs.
