Just How Cheap Is Solar Electricity
Production costs for solar energy have dropped by 90% between 2009 and 2020, according to US investment bank Lazard.
In 2020, electricity from large-scale solar plants cost a global average of just $0.037/kWh. By comparison, the costs of generating electricity from new coal-powered plants was three times that at $0.112/kWh, while natural gas cost $0.059, nuclear $0.163, and wind $0.04/kWh.
“We’re going to see solar power plants all over the world. It’s the cheapest energy source in the world, with a few exceptions. In some places, wind power is still a bit cheaper,” said Christian Breyer, a professor of solar economy at LUT University in Finland.
With large solar farms, Breyer says, production costs can be as low as $0.01 in locations with lots of sunlight, and up to $0.04 elsewhere. He and other experts expect that new and more efficient solar panels will lower costs even more, by 5 to 10% per year.
Levelized Cost Of Energy
The following table shows the Levelized Cost Of Energy for various sources of electricity. LCOE is the most popular method of comparing the cost of different complex energy technologies. It is the total life cycle cost of electricity for a given technology divided by the total life cycle electricity produced, expressed as dollars per million watt hours . The table below, derived from LCOE costs developed by the US Energy Information Administration in February, 2019, “estimates” the average LCOE over a 30 year period for different energy sources that are brought online in the year 2023. The year 2023 is used for comparison as that is a realistic time frame for a new plant to come on-line.Energy Plant Type
Notes: CCS stands for Carbon Control and Storage in a remote underground location.
“New” conventional coal plants without CCS and “new” Peaker Natural Gas plants are not allowed in the year 2022.
PV solar is much cheaper than coal with CCS and it is unlikely that any new coal fired plants will be built in the US. The Petra Nova facility, a coal-fired power plant located near Houston, Texas, is one of only two operating power plants with carbon capture and storage in the world. It is the only CCS facility in the United States. So CCS of any kind is not currently a major competitor to solar. Solar costs have been coming down dramatically. They are expected to slow down somewhat, but will continue to decline from the levels used in the LCOE calculations above.
The Invention Of Solar Panels By Usa
Solar panels were invented in the States back in the 1800s. The technology was lucrative, but profits were nowhere to be seen. The cost of solar was simply too high and energy store non-existent. Then, in the 1900s, American scientists created silicone solar panels and made solar power much cheaper. There was still no solar energy market and the few solar panel systems that were produced were mostly of the experimental value.

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.
What Does Solar Electricity Cost
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.Avg. US Installed Capital Costs – 2018
|Cost Per Watt|
|Utility Scale – Tracker||$1.13|
According to the National Renewable Energy Laboratory , located in Golden Colorado and Washington DC, the average residential household in the U.S. installs a 5 kWh system and it cost on average $2.70 per DC watt or $13,500 before incentives. Utilities on the other hand typically install systems in the 100 mega-watt or greater range. The average installed “fixed” utility system cost was $1.06 per watt and $1.13 per “tracker” watt. Top

How Much Does It Cost To Install Solar Panels
The average cost to install solar panels in the United States is about $12,000 after federal tax incentives. On the low end, you can install a smaller system for around $5,000, while a high-priced Tier 1 solar panel system can cost $40,000 or more.
There are additional costs that go into an installation project beyond the price of panels. In fact, only about a quarter of the installation costs are actually for the panels. Labor costs, operational costs and additional equipment, such as inverters and control circuitry, make up the rest of the price.
Solar energy companies install the solar panels, provide maintenance and offer warranties on both the panels and the work. These additional services arent free, but they are often worth it. A few additional factors affect the price of solar panel installation.
Diy Vs Hiring A Professional Solar Installer
DIY kits fall around $1 to $2 per kilowatt. Considering that having the entire process handled by a professional contractor averages around $2.50-3.50 per kilowatt, you may not be looking at a lot of savings.
|$25,000 – $35,000|

Solar Power For The Home: Benefits
A significant benefit to PV installation is a lower energy bill, but the magnitude of this benefit depends on the amount of solar energy that can be produced given the available conditions and the way in which utilities charge for electricity.
The first consideration is the solar irradiation levels available in the home’s geographical location. When it comes to using solar panels, being closer to the equator is generally better, but other factors must be considered. The National Renewable Energy Laboratory produces maps for the U.S. showing solar irradiation levels the tools on its website provide detailed solar information for specific locations within the U.S.
Similar maps and data are available in other countries as well, often from government environmental agencies or renewable energy organizations. Equally important is the home’s orientation for rooftop arrays, a south-facing roof without trees or other objects obstructing sunlight maximizes the available solar energy. If this is not available, panels can be mounted on external supports and installed away from the house, incurring additional costs for the extra hardware and cables.
The final benefit is the potential effect on a home’s value due to the addition of a solar array. In general, it is reasonable to assume that solar panels would raise the value of most homes.

Solar Power Plant In India
India is one of the largest power generation portfolios. The demand for clean energy in India is huge and is continuously increasing. Therefore, the Indian government has launched the Jawaharlal Nehru National Solar Mission on 11 January 2010, which aims to produce 227 GW of solar energy by 2022. It is a three-phase mission that aims to install 20,000 MW on-grid solar power plants, 2000 MW off-grid solar power plant including 20 million solar lights, and to create favorable conditions for developing solar manufacturing capability in the country.
Longevity And Sustainability Of Solar Energy
Many people dont realize it, but commercial electrical power is a commodity. Its bought and sold based on supply and demand. When you draw from the power grid, youre subject to current market forces and user rates. Youre not protected from future costs. Thats because futures are unpredictable.
Most futurists predict the world will be less dependent on fossil fuel over the coming decades. Coal and gas-fired electrical generation stations will be more regulated on emissions and their carbon footprint. That means more costs for fossil fuel generation and that has to be passed on to the consumer.
Hydroelectricity is the main power source in areas that have a suitable water supply to turn generators. But the expansion of hydroelectric production means additional flooding. Thats not acceptable in areas where land is a premium. Hydro plants have a limited capacity for output and are already maximized in many stations.
Alternate electrical sources like nuclear plants have dubious futures. Given the volatility of accidents and the nuclear waste problems, the future of nuclear power generation is bleak. That leaves a virtually untapped renewable power source the sun. Solar power is the future solution to low overhead electrical production.

How To Set Up A Solar Power Plant
Setting up a solar power system for your home or business involves many steps. The first phase is about making decisions. Begin by determining the size of the project and how much energy you need, then choosing an appropriate type of panel that will work best in your area. Next comes selecting where on your property you want to mount it, as well as what kind of mounting structure youll use. Finally, decide whether youre going with grid-tied or off-the-grid systems.
The second phase includes designing the electrical wiring needed to connect all components. This can be done by hand using wire nuts and connectors, but most people prefer to hire professionals specializing in this field.
The third stage consists of installing panels at their chosen location. Once they are installed, panels must be connected to each other and the rest of the circuit through junction boxes. Panels should also have wires attached to them so they can be wired into the main breaker box.
After everything has been completed, panels must be tested before being hooked up to the utility companys meter. If there are any problems during testing, panels may require additional repairs before installation can continue. Once the entire setup process is complete, panels begin producing electricity immediately.
What Is In A 10kw Solar Power System
To have an idea about the cost, we need to break down the whole system into its basic components. We will determine the bill of quantity or BOQ of the 10kW solar power system.
A solar power system consists of four basic components. These are the solar panels, the inverters, the mounting structures, and the balance of the system .
The quantity of each component will base on the total capacity of the system. This means as the kW increases, the number of materials for each component will also increase.
Considering a 10kW or 10,000-watt system, we can break it down into its basic parts as follows:

How Much Land Is Needed For A Solar Farm
Large solar projects have some requirements that need to be met in order to work.
According to GTM Research, a 1 MW solar farm will need 6 – 8 acres of land.
This gives room for all of the equipment needed as well as space between each panel row.
Large solar projects need space for the solar panels as well as the equipment that goes along with making it function, such as inverters.
The rows of panels need to have space for repair and maintenance access and the space is given so that there arent any shadows from the adjacent solar panel.
Lastly, the land must be open, without obstructions that can cause shade over the solar panels.
Land that is in direct sunlight is ideal – free of trees or nearby tall buildings, barns, etc.
The Future Of Solar Farms
Moving forward, community solar projects, utility-scale solar projects and rooftop solar will all be part of the renewable energy solution providing clean energy around the US and replacing fossil fuel power.
Large-scale solar will continue to get cheaper as developers of solar farms find more ways to reduce financing costs and equipment costs keep coming down. Expect to see many more solar farms, and even bigger ones, in the near future.
