What Does Solar Electricity Cost

How much do solar system batteries currently cost per kWh ...

As shown in the chart at the left, photovoltaic solar cell prices have come down by a factor of 100 over the last 38 years and down by a factor of 25 over the last 15 years. The sharp drop in 2009 and 2010 was because of too much capacity, especially in China, which has caused prices to collapse. The 2015 average solar “cell” price was $0.30 per watt and the average solar “module” price was $0.72 per watt.

Since costs after installation are minimal for solar electricity, the relevant costs are the purchase price, installation costs, and the cost of land . Cost components that make up a residential solar system are: system design, solar modules, and the balance of system which consists of an inverter, bi-directional billing meter, connection devices, and installation labor.

In the southwest, installed residential solar prices are competitive with residential electricity prices after incentives.

Factors That Contribute To The Cost Of Solar Panels

There are many factors that contribute to the cost of solar panels. Understanding the how and why of any cost variance will help you plan your solar installation accordingly. Lets review the elements that impact the overall cost of your solar system and how you can use them to your advantage.

The cost of solar panels has become more and more affordable as the industry grows. In fact, government incentive programs have allowed homeowners to install solar panels at a reduced cost. However, the type of solar panel system, property location, and the size of the system are variables that greatly impact the overall solar panel cost. When you are considering going solar, you should also consider these factors to determine the right system and method of installation for you.

Average Cost Of Solar Energy

As the total cost of going solar in the USA has been on the decline in the past decade, the federal tax credit was introduced to bring the average total cost even further down. Solar is now cheaper than coal or natural gas and the national average price for solar panels has dropped by around 80%.

Nowadays, solar arrays are not reserved for experimental purposes only, but residential system size is more affordable than ever. A typical 5kW system used to cost $40,000 back in 2010. Today, that same system costs less than $18,000, for a premium product.

As new breakthroughs are made in the technology, every solar installer will be able to offer even large system-size solar arrays for a much lower price. The increasing efficiency and mass production are sure to bring average prices on both per W and per kWh down significantly. The US Energy Information Administration announces that with reduced prices, the total solar capacity in the USA could increase by 81GW from 2019.

How Many Solar Panels Will You Need

To know how many solar panels you will need, you will want to determine how much electricity you use in your home and the solar panel types installed.

The average house in the United States uses about 900 kilowatt hours a monthroughly 11,000 kWh a year. You can easily calculate your actual usage by looking back at your electricity bills. As a general rule of thumb

  • A 3-kWh solar panel system will generate about 3,600 kWh 4,800 kWh per year.
  • A 5-kWh system produces about 6,000 8,000 kWh per year.
  • A 10-kWh system can produce about 12,000 kWh 16,000 kWh per year.

Depending on the size of the system, the solar panels cost would be between $4,000 and $16,000. Add in another $3,000 to $10,000 for other necessary components, such as racks for the panels, wiring, solar inverter costs, and the total solar panel installation cost would now be closer to $20,000.

Why Is Solar So Cheap Now

  • Panel price has plummeted. The cost of solar panels has taken a deep, deep dive in recent years. So much so that I don’t expect them to continually get much cheaper, but then again, they don’t have to, because they’re already affordable.
  • Federal Tax Credit of 30%. If you install a $20,000 system, you lower your tax bill by $6,000. The credit is 30% of your cost, after any state/local rebates you get. Note that a tax is more powerful than a tax deduction. A deduction just reduces the amount of your income, on which the tax is based. But a tax comes directly off your total taxes. The credit is set to expire at the end of 2016 unless Congress renews it, but even if they don’t, solar should still be affordable.
  • State & local rebates. This is cash back from the government or utility company for installing solar. But they’re becoming increasingly rare, since solar costs have dropped so much that governments don’t feel they have as much need to subsidize it.
  • SRECs . In some northeast states, you earn credits called SRECs from generating rooftop solar, which you can then sell in a marketplace for about 15¢/kWh. SRECs aren’t available in most states, but where they are, they make the systems essentially free. I have a separate page .
  • Increased Competition. Now that solar is getting popular, more installers are entering the market. When there was just one installer in your area they didn’t have to try very hard to get your business if you wanted solar. Now they do.
  • Frequently Asked Questions About The Cost Of Solar

    How Much do Solar Panels Cost in California?

    Solar energy cost has plummeted in the past decade. The average cost of solar panels is less than half what it was ten years ago.

    As of the time we updated this page , most solar panel prices fall in the range of 60 cents to 70 cents per watt. Premium panels can climb above $1 per watt depending on their size, quality, and where they are manufactured. Our solar panel calculator uses standard size panels to estimate the cost of your system.

    Solar panel installation cost varies by provider. A turnkey solution will charge 100-200% the cost of equipment to perform the installation.

    If your 6.6 kW system costs $10k in equipment, they may charge you $20k for the installation, bringing the grand total for the project to $30,000.

    The other option is to buy direct from a distributor and either install it yourself or hire a local contractor to do it for you. If you choose the self-install solar panels, we have instructional videos and a brilliant tech support team to walk you through the project. Some people spend less than $1000 installing their own system .

    Even if you hire a local contractor, theyll charge you somewhere between 75 cents and $1.25 per watt. Theyd install the system above for around $6000-$7000, which is less than half the amount youd pay to a turnkey installer.

    Thats why youre here! Our solar power calculator takes the information you provide about your energy usage patterns and returns our best guess about how much solar energy you might need to generate.

    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.

    Why Solar Panel Cost Should Not Be Your Only Consideration When Buying Solar Panels For Your Home

    The most important difference between buying solar panels and any other purchase is that solar panels last 25-30 years. This is a long, long time and you will need customer service over all that time. The reviews below of the two largest corporate solar installation companies indicate larger corporate solar companies are not delivering this support to their customers.

    We recommend you find a small or mid-size, local, family-owned solar company. These companies tend to care more about you and your specific job. You don’t want to be on hold to a corporation’s call center for the next 25 years!

    Estimating The Cost And Energy Efficiency Of A Solar Water Heater

  • Estimating the Cost and Energy Efficiency of a Solar Water Heater
  • Solar water heaters are more efficient the gas or electric heaters. | Chart credit ENERGY STAR

    Solar water heating systems usually cost more to purchase and install than conventional water heating systems. However, a solar water heater can usually save you money in the long run.

    How much money you save depends on the following:

    • The amount of hot water you use
    • Your system’s performance
    • Your geographic location and solar resource
    • Available financing and incentives
    • The cost of conventional fuels
    • The cost of the fuel you use for your backup water heating system, if you have one.

    On average, if you install a solar water heater, your water heating bills should drop 50%80%. Also, because the sun is free, you’re protected from future fuel shortages and price hikes.

    If you’re building a new home or refinancing, the economics are even more attractive. Including the price of a solar water heater in a new 30-year mortgage usually amounts to between $13 and $20 per month. The federal income tax deduction for mortgage interest attributable to the solar system reduces that by about $3$5 per month. So if your fuel savings are more than $15 per month, the solar investment is profitable immediately. On a monthly basis, you’re saving more than you’re paying.

    How to calculate the cost per unit of electricity generated by a Solar PV power plant?

    To add some much needed transparency to the industry, the cost of solar power will be completely explained here.

    The current average low-end cost of solar power As of early 2021,is approximately $2.00 per watt, installed. The average sized solar panel system is 5,000 watts, so this brings the total cost to $10,000. That 10k figure is just an average amount. Systems can cost more or less mostly depending upon a homeowners energy usage.

    The typical solar installer does not make the price of solar easy to find online. This is unfortunate, as more homeowners would go solar if they knew how much they could save over the long term. The average homeowner would save at least $25,000 over 25 years by investing in a solar panel system.
