How Big and Expensive Is a 20 kwh battery storage?

A 20 kwh battery storage system is going to cost you around $12,000.


The exact cost depends on where you live and how much electricity costs in your area. But generally speaking, a 20 kW solar system will cost between $10,000 and $15,000.

That means that the batteries alone will cost about $5,000-$7,000.


If you’ve been thinking about installing a solar system, you’ve probably wondered how big and expensive they are. The answer is: pretty big and pretty expensive!


A 20 kW solar installation is almost 4 times bigger than the average 5.6 kW home solar installation in the United States. If your electricity usage is high compared to the national average of about 900 kilowatt-hours per month, then a 20kWh battery storage system might be right for you. But if you’re just looking for something for your RV or boat, then a smaller system will be more cost-effective.

If you’re interested in installing a 20 kW solar system, chances are this is a commercial installation or your electricity use is really high compared to the national average of about 900 kilowatt-hours per month. Maybe you live in an area that regularly sees summer temperatures over 100 degrees F and so you have to crank that air conditioning all summer to stay comfortable (AC is one of the biggest users of electricity in our homes!). Or maybe you live in a large house (read: mansion), so you have a lot of lighting and space to air condition. If this is the case, great! You are a prime candidate to go solar.


20 kwh solar system


A 20 kW solar installation can be installed on rooftops with an area of 1,372 square feet.


This means that if you have a standard 2-car garage, or an average-sized shed (around 200 sq feet), you’ll be able to install a 20 kW solar installation. In fact, if you have a large yard and want to install a 20 kW solar system in your backyard, you could use the same amount of space for your installation. But if you have a smaller yard and want to go bigger than 20 kW, it might be difficult to find enough space for all the panels needed to produce enough electricity for your home.


How much does a 20 kwh solar system cost?


The average cost to install a residential solar installation, according to the National Renewable Energy Lab, is $2.93 per watt. So, a 20-kilowatt installation that you pay for in cash upfront would total around $58,600!

That’s a staggering number, to be sure! However, solar homeowners are eligible to receive numerous federal, state, and local financial incentives to drive this cost down. For example, when we apply for the 30% federal Residential Renewable Energy Tax Credit, that total cost drops down to $41,020—almost $20k less! Now we’re getting somewhere!

Check on your online for what additional incentives are available in your area. A great tool for this research is the federally-sponsored DSIRE (Database of State Incentives for Renewable and Efficiency), which summarizes all the different incentives available for going solar in each state, which can include anything from upfront rebates for a portion of the total cost to state sales tax exemptions and property tax exclusions.

If you have been considering installing a 20 kW solar system, you are probably wondering how much money you can save by switching to solar energy. Well, we have good news: it’s a lot! In fact, if you install a 20 kW system, you could save over $66,000 over the life of the system.


How much money can I save with a 20 kW solar system?


How much a solar installation costs is important, but the real question is how much you can save. A solar installation is big money, but if you can save even bigger money over the life of the installation, then it’s all worth it, right? Well, installing a 20 kW system means big savings! Read on to see how.

To calculate the financial savings of a 20 kW solar system, we need to compare your total solar installation cost to your total cost of continuing to purchase electricity from the utility. Most in the solar industry usually assume a solar installation to last between 20 and 30 years, so we’ll split the difference and use 25 years in our calculations.
