Theres More To The Solar Cost Story
Its great that weve arrived at the average cost of a solar system installation but as you may have guessed, there are many different factors that influence what the cost of solar would be for you.
Size of Your Solar System
5kW is the average size of a solar system, but many people choose to install bigger systems. A bigger system means more energy production and more energy savings over time. Some popular sizes are 6kW, 10kW and 15kW. Of course, it really depends on what your energy needs are. If you have 1500 square foot house and few appliances, your energy needs will be much different than someone who has a 3,000 square foot house with a hot tub!
The best thing you can do is run a simple analysis on your energy bill. How much energy do you use? Take that and you can easily decide what the size of your residential solar system should be.
Where You Live
The cost of solar installations varies from state to state, however the price of solar is actually fairly steady across the board. Almost all states tend to fall within 50 cents of the $2.96/watt average we discussed earlier.
Where you live certainly affects your solar savings but that is a topic for our aforementioned solar savings page.
Energy Sage also has a great breakdown of state by state solar installation costs!
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.

Find How Much Energy Solar Panels Produce In Your Area
Now that you know how much electricity your home uses in a month, you need to find the amount of sunlight your area receives. This is usually measured in something called peak sun hours, which is essentially the intensity of sunlight in your area.
You can find the average number of daily peak sun hours for your state here. This number is how much sunlight you receive daily, but we need to know how much you receive monthly. To do this, simply multiply your states daily peak sun hours by 30.
The monthly peak sun hours you get tells you how many kWh of electricity 1 kilowatt of solar panels will produce in your area in one day. So, if your state receives 150 monthly peak sunlight hours, 1 kW of solar will produce 150 kWh of electricity per month.
Not sure about the differences between kW and kWh? Read our guide about kW versus kWh and what they mean.
How Many Solar Panels Do I Need
Your energy needs determine how many panels you need, which affects the overall price of your solar system installation. To eliminate your electric bill entirely, you must generate 100% of the electricity your home needs. Most homeowners need between 25 and 35 panels to achieve complete energy independence.
Average households need867 kWh/monthin electrical power
A solar panel typically produces about one kilowatt-hour per day, so if your daily kWh usage is 30, you would need 30 solar panels to generate all of your energy needs. If you need to generate extra energy to heat a pool or run the air conditioning for most of the year, this adds to your energy costs.
To estimate the amount of energy youll need, you need to know your average kilowatt-hours . This number should be on your utility bill as kWh used. To get your monthly average, look at bills for the past year, add up the stated kWh used and divide by 12.
Next, divide your monthly kWh average by 30 to calculate your daily average. For instance, if your average monthly kWh is 900, then your average daily kWh is 30.
For a more accurate calculation, try to factor in times when there is not as much solar power available, like when its cloudy or in the evening. There are two main ways to account for this:
These additional calculations can be difficult, but they are necessary if you want the optimum solar power system for your home.

How Much Do Solar Panels Cost To Maintain
Sadly, once your solar system is in place, you are still going to have to pay a little money per year to keep it running efficiently. Here are some solar panel maintenance costs.
- Annual solar inspections
Lets examine what each area entails and how much you can expect to pay for each type of maintenance.
How Many Solar Panels Do You Need For A 2000 Sq Ft Home
Estimating the number of panels based on home area is an indirect approach, since you must assume the kWh consumption. Some homes have more efficient appliances, and habits also influence electricity usage. However, average values can be calculated from official data:
- The US Energy Information Administration estimated that the average home uses 867 kWh monthly
- The US Census Bureau determined that single-family homes have an average area of 2467 square feet
- When dividing these values, you obtain 0.35 kWh per square foot
Assuming 0.35 kWh for a 2,000 sq. ft. home, the estimated electricity consumption is 700 kWh. At this point, you can use the calculation procedure described in the previous section. Considering 6 peak sun hours per day and 300-watt panels, you need 16 to produce 700 kWh each month.
If you have limited roof space, the best recommendation is installing the most efficient solar panels available. This will maximize the watts installed per square foot, compensating the area limitation. Finding out how efficient solar panels are is simple: you must only divide their individual wattage and area. The panels with the most watts per square foot have the highest efficiency.
