How To Determine How Many Solar Panels You Will Need

Taking into account the factors in the section above, a simple formula to use to estimate the size of the system that you need is kWh per year / 1200 = the size system you need . Our actual system design will take many other factors into account, but this should be a good estimate. Once we have the kW needed, we will select the number of panels by reviewing your available roof space and your target budget. For example, if space is an issue, we will need to select a higher efficiency panel to keep the footprint small and the production high. Likewise, a cheaper panel could be selected if there is more available space to work with.

You can do the math or better yet, use the examples we compiled for you to get a ballpark idea of the number of panels youll need. We suggest contacting a solar installation professional to determine the exact size for a system that best fits your needs. In the meantime, this chart is a good reference point.

How Much Power Am I Using

A kilowatt-hour is a basic unit of energy, which is equal to power times time . Your electric bills show how the average number of kWh you use per month.

For example, a 50 Watt light bulb left on for one hour would be 50 Watt hours, and 20 50 watt light bulbs running for one hour would be 1 kilowatt-hour . According to the U.S. Energy Information Administration, the average monthly electricity consumption for a residential utility customer is about 903 kWh per month.

Divide your average monthly usage by 30 days in a month to get your daily usage. If youre going by the national average, then you should be using about 30 kWh per day. Next, figure out the average amount of sunlight you get per day. The US ranges from about 4 hours 6 hours of sunlight per day, on average, see the below map. Lets estimate you get about five hours per day to generate that 30 kWh you use. So the kWh divided by the hours of sun equals the kW needed. Or, 30 kWh / 5 hours of sun = 6 kW of AC output needed to cover 100% of your energy usage.

For a 10kW solar power system, you will need at least one solar inverter unit. As for the cost percentage, this component will amount between 15% up to 25% of the total system cost.

We want to invite you to read our article about the best 10kW inverters today for you to have an idea of what your options are.

What is a solar inverter?

One of the major components of a solar power system is the inverter. It comes in different shapes and sizes. Sometimes, it is installed outdoors or in the field together with the solar arrays. But, most of the time, it can be found under the shade or even indoors.

The inverter is the heart of the solar power system. Its main purpose is to transform DC power from solar arrays into useful AC electricity. This will then be used for homes or other establishments.

What are the different types of solar inverters for a 10kw PV system?

There are many types of inverters that are available right now. We will just focus on the inverters, which will apply to a 10,000-watt solar power system. We can consider these two types:

Micro Inverters

A micro inverter is the type of inverter which is directly connected to a single solar panel. It is installed just underneath the solar module. It also means the number of modules will determine exactly how many micro-inverters you need.

Calculate 10kw Solar System Battery Requirements

Figuring out solar battery requirements is a bit complex because the needs vary from one household to another. What follows is a simplified process.

Total solar array output / battery voltage = battery amps required

A 10kw solar system produces 40kw a day, or 40,000 watts. Divide the wattage by the battery voltage and you have the answer. Batteries come in different voltages but we will use 48V as it is the most practical for large PV systems.

40000 / 48 = 833.3

You need a 48V battery bank with at least 833 amps. For instance, you can buy 3 x 300ah 48V batteries, 4 x 200ah, 2 x 450ah, any combination as long as it is at least 833ah.

You can use 24V or 12V batteries of course. Connect them in a series to increase the voltage so it can handle the system output. The only drawback is you have to double the number of batteries required.

If you use 24V batteries, you will need 1666 amps. The best option would be a 24V 300ah capacity like the Shunbin LiFePO4 Battery as it can handle the power. You will need 6 of these for a 10kw solar sytem.

If you need 3 x 300ah for 48V batteries, you will need 6 of these for 24V batteries and a dozen for 12V. Batteries take up a lot of space and are heavy. More of them also means more wiring required which adds up to the cost.

How Much Electricity Will A 10000 Watt Solar System Produce

The amount of electricity that a solar energy system will produce will depend on a number of factors, including the quality of the parts used in the system and the angle and orientation of the solar panel array. If you are looking for a 10,000 kWh solar system, 10 kW of solar panels will produce more than enough electricity for your needs.

The most important factor determining exactly how much electricity your panels will produce is the amount of sunlight that shines in your area throughout the day. For example, all things being equal, a 10kW solar system in southern California would produce about 20% more electricity over the course of a year than a system in the Northeast.

The following table shows average daily, monthly and annual solar energy production numbers for a 10kW solar system in various US cities. As you can see, systems located in sunnier cities produce more electricity than less sunny cities.
