In March 2021, Electrek reported that researchers published a feasibility study on the benefits of erecting solar panels over canals. That study is about to become a reality as a pilot project breaks ground in California.
Solar over canals
Update August 26: Project Nexus in the Turlock Irrigation District, a $20 million project funded by the State of California, will break ground in mid-October at two locations: To see also : NASA’s Lucy stretches its wings in successful solar panel deployment test.
Josh Weimer, Turlock Water & Power’s head of external affairs said [via Reuters]:
If this is something that works in these first two miles of Project Nexus like we are doing, there is the potential for this to be scaled to more places.
If all 4,000 miles of California’s canals were covered with solar panels, it could produce 13 gigawatts of renewable power. One gigawatt is enough to power 750,000 homes, so there will be enough electricity for 9.75 million households. For perspective, as of July 2021, there were 13.1 million households in California.
March 1: The California Department of Water Resources, utility company Turlock Irrigation District (TID), Marin County, California-based water and energy project developer Solar AquaGrid, and the University of California, Merced, are collaborating on Project Nexus — a “nod” to that water -the energy nexus paradigm is gaining attention among public services.”
India already has solar panels over canals, but the mile-long Project Nexus in California’s San Joaquin Valley will be the first of its kind in the United States.
Project Nexus includes the installation of solar panels over various sections of Turlock Irrigation District (TID) irrigation canals. Project Nexus will serve as a Proof of Concept to pilot and study solar energy in relation to channel design, deployment and co-benefits on behalf of the State of California using TID infrastructure and electric grid access.
The project is expected to break ground in autumn 2022 and be completed by the end of 2024.
Project Nexus will provide the opportunity to see if the solar panels reduce water evaporation as a result of midday shade and wind attenuation; creating improvements to water quality through reduced vegetative growth; reduce canal maintenance as a result of reduced vegetative growth; and of course generate renewable electricity.
Roger Bales, Distinguished Professor of Engineering at the University of California, Merced, who is working on this project, wrote in Conversation:
Most of California’s rain and snow falls north of Sacramento in the winter, while 80% of water use occurs in Southern California, mostly in the summer. That is why canals snake across the state – it is the largest such system in the world. We estimate that about 1-2% of the water they carry is lost to evaporation under the hot California sun.
In a 2021 study, we showed that covering all 4,000 miles of California’s canals with solar panels would save more than 65 billion gallons of water annually by reducing evaporation. It is enough to irrigate 50,000 acres of agricultural land or cover the water needs of more than 2 million people. By concentrating solar installations on land already in use, rather than building them on undeveloped land, this approach will help California meet its sustainable management goals for both water and land resources.

In December, they proposed a tax of up to $700 a year for those who use solar panels. That proposal also cut the amount solar users were paid for the energy they put back into the grid.
What is the California solar tax credit for 2022?
The 26% federal tax credit is available for purchased home solar systems installed by December 31, 2022. This may interest you : U.S. wind and solar power reached a key benchmark last month: the report. Exclusion of property tax on the home value from the rooftop solar system.
Is There a California Tax Credit for Solar Energy? Federal Solar Tax Credit Most California residents are eligible to receive the Federal Solar Tax Credit – also known as the Residential Clean Energy Credit. Originally known as the Investment Tax Credit (ITC), it covers up to 30% of the cost of installing a solar panel system.
Will there be solar tax credits in 2022?
In December 2020, Congress passed an extension of the ITC, which provides a 26% tax credit for systems installed in 2020-2022, and 22% for systems installed in 2023. (Systems installed before December 31, 2019 were eligible for a 30% tax credit.)
Does California have a solar tax credit 2022?
Federal Solar Investment Tax Credit (ITC)** Purchase and install a new home solar system in California in 2022, with or without a home battery, and you may qualify for a 26% federal tax credit. The ITC for homes drops to 22% in 2023 and ends in 2024.
Does CA allow solar tax credit?
Although California does not offer a state solar tax credit, all residents are eligible for the applicable federal solar tax credit. Solar tax credits are worth 26% of the value of the system installed and can be claimed on federal tax returns.
Is there a tax credit for solar panels in 2022?
In December 2020, Congress passed an extension of the ITC, which provides a 26% tax credit for systems installed in 2020-2022, and 22% for systems installed in 2023. (Systems installed before December 31, 2019 were eligible for a 30% tax credit.) The tax credit expires starting in 2024 unless Congress renews it.
What is the California tax credit for solar in 2022?
If a solar installation is commissioned in 2022, you will qualify for a tax credit of 26% instead of 22%. You must purchase the system to claim ITC. Consumers cannot claim the tax credit for leases or power purchase agreements (PPAs).
What is the solar tax credit worth in 2022?
| Year put into use | Federal Solar Tax Credit |
|---|---|
| 2021 | 26% |
| 2022 | 26% |
| 2023 | 22% |
| 2024 | 10% (for commercial installations only) |
How much is the 2022 solar tax credit?
In December 2020, Congress passed an extension of the ITC, which provides a 26% tax credit for systems installed in 2020-2022, and 22% for systems installed in 2023. (Systems installed before December 31, 2019 were eligible for a 30% tax credit.) The tax credit expires starting in 2024 unless Congress renews it.
How much of a tax credit do you get for solar panels?
The Investment Tax Credit (ITC), also known as the Federal Solar Tax Credit, allows you to deduct 30 percent of the cost of installing a solar energy system from your federal taxes.
How do I get the 2022 solar tax credit?
First, download IRS Form 5695 as part of your tax return. Then calculate the credit on Part I of the tax form. You register your solar system as “qualified solar electric property costs”. Then, on line 1, enter the project’s total cost as written in your solar contract. Complete the calculations on lines 6a and 6b.
Can you sell electricity back to the grid in California?
California Assembly Bill 920 allows PG&E and other state utilities to offer payment for excess energy sent back to the electric grid by home or business renewable energy systems.
Can you sell solar power back to the grid in California? If someone doesn’t use up all the solar energy their panels collect, they can sell it back to the grid. Under the state’s “net metering” program, they can sell it at the same retail price they would buy electricity at. The program will help people recoup the cost of installing their solar system.
How much can I sell electricity to the grid for?
So how much money can you make selling electricity back to the grid? Since prices vary with the market value of electricity, there is no set dollar figure you can expect to take home. However, many home producers earn about $3,000 per year from a combination of REC sales and government clean energy incentives.
Can you make money generating electricity?
But did you know that you can also make money from the electricity company? This involves selling electricity back to the company’s grid, if you have a surplus from your renewable energy source. So if you are thinking of generating renewable energy on your property, these solar panels can make you money.
How much do I get for selling electricity back to the grid California?
They estimate that the actual value to the grid is around 5 cents per kW. But someone with a home solar system can make 30 cents per kW because they sell it at retail price, which is higher because it includes costs like grid maintenance.
How much money can you make selling power?
But on average you can earn around $50-$700 per month. How much you actually get paid depends on factors such as how big your system is and what time of day it produces energy.
Can I sell my energy back to the grid?
Provided your house is connected to the national grid, you can sell any excess electricity you generate back to your energy supplier (although getting the necessary paperwork done is sometimes difficult). Selling electricity is one of the best ways to earn passive income for your household.
How much money can you make selling electricity back to the grid California?
You can expect around $0.15/kWh in California and $0.08-0.09/kWh if you live elsewhere.
Why should solar panels face south?
Which way do solar panels face? The conventional recommendation is that a roof orientation should face south for best exposure to the sun. Although south-facing roofs will have the most direct exposure to sunlight, the takeaway is that your roof doesn’t need to face south for solar to make sense.
Should solar panels face due south? Solar panels do not have to be south-facing, but you will get the most effect from a south-facing system. It is better for solar panels to face south in the northern hemisphere rather than east or west. North-facing roofs are the least optimal location for panels.
What if my roof does not face south for solar panels?
Even if your panels don’t face directly south, your system can still produce large amounts of electricity. If your house is oriented east or west, you will only see a 20 percent decrease in energy produced.
Why do solar panels have to face south?
In the northern hemisphere, the sun moves in a slight arc with a southern offset. Therefore, the general practice has been to install solar panels facing south to capture the most sunlight possible.
Do solar panels always have to face south?
Solar panels don’t just need to be pointed in one direction; a homeowner can buy a device called a tracker that will swing them throughout the day, like a sunflower, so they always face the sun. A tracker can increase the performance of a panel by 45 percent.
Can you put solar panels on north-facing roof?
When it comes to deciding where to place your solar panel, experts agree that a south-facing orientation is best for solar energy. But a north-facing solar roof can produce a lot of electricity, proving that there can be exceptions to the rule.
Why more solar panels should be facing west not south?
West-facing solar panels receive the most sun at this time and therefore displace more grid energy during these periods of high demand. One study found that west-facing panels generated almost 50% more than their south-facing counterparts during peak demand hours when normalized for a 5.5 kW system.
Is west or East better for solar?
Because north-facing solar panels produce the most electricity overall, they will have the greatest environmental benefit. West orientation: West-facing panels produce around 15% less electricity overall than north-facing solar panels. They also produce less electricity in the morning, but more in the afternoon.
What is the best direction to face solar panels?
In the Northern Hemisphere, the general rule for placing solar panels is for solar panels to face true south (and in the south, true north). Usually this is the best direction because solar panels will receive direct light all day.
Does solar panel direction matter?
The orientation of your solar panels does not affect the output of your system. In the US, panels are usually installed vertically by default unless you have a flat roof that better allows for horizontal panels since they don’t stick out as much.
What direction do my solar panels need to face?
So, what is the best direction for solar panels? For homeowners living in the northern hemisphere, the rule of thumb is that solar panels should be oriented to true south. (For those in the southern hemisphere, solar panels should be oriented towards true north.)
What solar panel exposure is best?
This means that the sun is above the equator and therefore your solar panels will be most efficient if they are south facing. South facing panels will face the sun all day. This gives them the maximum possible time to collect sunlight and convert it into energy.
What direction should solar panels face?
In the Northern Hemisphere, the general rule for placing solar panels is for solar panels to face true south (and in the south, true north). Usually this is the best direction because solar panels will receive direct light all day.
Is it better to face solar panels East or West?
Best solar panel orientation in general. South is the best direction for solar panels to face in general. In almost all cases, homeowners will achieve the highest energy bill savings and fastest payback time by facing the solar panels south over any other direction.
What direction does my house need to face for solar panels?
For homeowners living in the northern hemisphere, the rule of thumb is that solar panels should be oriented to true south. (For those in the southern hemisphere, solar panels should be oriented towards true north.)
Which direction should my house face for solar energy? South facing panels are definitely best and will produce the most energy. This is due to our location in the northern hemisphere and the fact that the sun is in the southern sky year round in our location. In summer, the sun is higher in the sky, but it is still on the south side.
Are solar panels better facing east or west?
Best solar panel orientation in general. South is the best direction for solar panels to face in general. In almost all cases, homeowners will achieve the highest energy bill savings and fastest payback time by facing the solar panels south over any other direction.
What is the best direction to face solar panels?
In the Northern Hemisphere, the general rule for placing solar panels is for solar panels to face true south (and in the south, true north). Usually this is the best direction because solar panels will receive direct light all day.
How effective are solar panels facing west?
A western orientation reduces their total output by between 10 percent and 20 percent compared to south-facing panels, and that means less electricity for homeowners and lower earnings from net metering.
Is west or east better for solar?
Because north-facing solar panels produce the most electricity overall, they will have the greatest environmental benefit. West orientation: West-facing panels produce around 15% less electricity overall than north-facing solar panels. They also produce less electricity in the morning, but more in the afternoon.
What direction does your roof have to face for solar panels?
The conventional recommendation is that a roof orientation should face south for best exposure to the sun. Although south-facing roofs will have the most direct exposure to sunlight, the takeaway is that your roof doesn’t need to face south for solar to make sense.
Does it matter which way solar panels face?
With a solar battery for the home, no matter which direction your solar panels face, as long as they are able to generate energy, you can store energy for consumption when electricity is most expensive, thereby maximizing your savings.
Can solar panels be installed on north facing roof?
When it comes to deciding where to place your solar panel, experts agree that a south-facing orientation is best for solar energy. But a north-facing solar roof can produce a lot of electricity, proving that there can be exceptions to the rule.
Why should solar panels face south?
A new study of 110,000 homes in California with rooftop solar systems confirmed that a large majority of the panels were pointed south because most of the panel owners were paid by the number of kilowatt hours the panels produced.
