How Much Does A 20 Kw 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!
Thats 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 the 30% federal Residential Renewable Energy Tax Credit, that total costs drops down to$41,020, almost $20k less! Now were 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 , 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. All these incentives drive your cost down even further, allowing you to save even more going solar!
$40,000 still a little too much? Solar companies know thats a lot of money for most homeowners. Thats why many solar installers offer leases, power purchase agreements, and loans to allow you to go solar with little investment though your savings are also going to be less than a cash purchase.

Minimal long-term expenses can make up for the upfront costs. Most systems dont require much maintenance and are designed to last for 20 years or more with little change to the amount of electricity produced, Nilsen says.
When calculating the total price, consider how much energy you regularly consume your usage is listed on your monthly utility bill and what size system will generate the amount needed. Some tools, like the SolarReviews calculator, estimate the system size for you.
With installation, an average residential 5kW size system costs between $3 and $5 per watt, according to the CSE, which results in the $15,000 to $25,000 range. That cost is before any tax credits and incentives.
If you know your current energy usage, you can calculate how much youll need to pay for solar panels.

Type Of Solar Panel Systems
The type of solar panel system you chose will greatly affect the cost. Grid-tie, grid-tie solar and energy storage, and off-grid solar are all options differ in price. Remember, the best solar panels for your property will fulfill your needs and meet your price point.
Lets break down the primary purpose of each system:
- Grid-tie: You have access to the utility grid. Your primary goal is to save money on your electric bill
- Grid-tie solar and energy storage: You have access to the utility grid and your primary goal is to have backup power when there is an outage.
- Off-grid: You do not have access to the utility grid. Your primary goal is to live where it is not accessible.
Once you identify your goals, you can make a final decision based on price.
If you have access to the grid, you can lower the cost of solar panels by using a grid-tie system. When you choose a grid-tie system with energy storage, you have the potential to save even more. Storing electricity in the grid doesnt cost anything, and you may be able to sell your stored energy . An off-grid system is a significant extra cost.
With an off-grid system, youll need to purchase batteries which represent almost half the cost of an off-grid solar system.
If you have the option, we recommend connecting a grid-tied system. However, off-grid solar will still save you money in the long run if you want to live away from a utility grid.
Browse our grid-tie solar kits and off-grid solar systems for up-to-date pricing.
Factors That Contribute To The Cost Of Solar Panels

How Much Do Solar Panels Save
Switching to a solar energy system could potentially cut your energy bill by 75%. The savings you and your family see will depend greatly on where you live, what the climate is like and your particular energy needs. For instance, an average homeowner in Portland, Oregon, will see total savings of $38,000, whereas a homeowner in Los Angeles could save as much as $90,000 over 20 years.
Many solar energy companies provide a free calculator tool to help you easily estimate the cost and savings of installing solar panels on your home. Different solar calculators may estimate electricity costs in different ways. Numbers can be based on the national average, regional averages or other information you provide.
The average American electric bill is between $100 and $200 per month, and the average yearly energy cost is about $1,500. Depending on how much you pay out-of-pocket for the solar panel system, it could take five to 15 years to break even. To calculate how long it will take you to break even on savings versus the cost of your solar panels, first subtract your incentives and rebates from your costs. Divide that number by the amount you are saving on utility bills per year.
Even if your solar panels generate 100% of your electricity needs, you may still receive a utility bill. However, instead of asking for payments, you will get net metering credits for the month.
Location Of Your Home
Lets get real here: A home in Phoenix will create more solar electricity than one in Portland whether Oregon or Maine even if both homes are completely bereft of trees.5 Geography is essential to the efficient generation of solar power. You can always install solar panels on your roof wherever you live, but where you are matters, too.

What Does It Mean To Go Off The Grid
Many people use solar panels to offset the cost of electricity, but this does not mean that they have gone off-grid. Using solar energy to offset energy costs means you are still connected to the local power supply and can use it if you need more energy than your panels produce.
To go completely off-grid, your entire home must run on electricity or energy that you produce yourself using solar panels and batteries. Your home cannot use any electricity from the town power supply. Installing solar panels is not enough to be considered off-grid, and most people who use solar energy still rely on electricity from an outside source. To go completely off-grid, you also need a storage system to smooth out energy production and usage over time. Finally, you need a way to transfer energy into the batteries and convert it to electricity.
Should I Get A Solar Battery
UK homes with solar panels typically use 50% of the electricity they create thats a lot of free solar energy going to waste.
The peak times in the day for people using electricity in their homes are the mornings and evenings, which is when the sun is either rising, setting, or gone completely.
Meanwhile, solar panels produce the most electricity in the middle hours of the day, when youre likely to be out and about. This all seems very silly and out of sync, but theres a clever bit of technology that can fix the problem.
If you add a solar battery into the mix, it will store the extra electricity produced by your panels that you arent at home to use. Then, during those mornings and evenings when you need power, your solar battery will keep you going until the sun comes back.
Thats right your solar panels, your solar battery, and the sun all working together to keep your home powered for free.
A solar battery will work wonders for your energy bills. According to E.ON, with a 9.6 kWh solar battery storage system in central England, you could use up to 30% more of the energy your solar panels generate, and reduce your annual energy bills by up to £560.
The cost of a solar battery generally ranges between £1,200 and £6,000, depending on the quality, capacity, and lifespan of the battery. Of course, the larger your solar battery, the more electricity youll be able to store, and the more money youll be able to save.
