When Does The Federal Solar Tax Credit Expire

PV-TV EPISODE 6: Solar Batteries, buy now or wait?

The federal solar tax credit is set to expire at the end of 2023. There is hope that the tax credit may be extended once again. The Biden Administration has plans to include a 10-year extension of the tax credit in future legislation. But, theres no guarantee that this will be approved by Congress and it may be at a lower rate.

Because of that, our best advice is to try and add solar panels as soon as possible so youre guaranteed to get the 26% credit.

The best time to go solar is now because the 26% ITC will decrease to 22% in 2023 before becoming unavailable for residential solar systems installed in 2024 and beyond.

What You Need To Know About Adding Battery Storage Such As The Tesla Powerwall To Your Home’s Solar Panel System

Home battery storage is a hot topic for energy-conscious consumers. If you have solar panels on your roof, there’s an obvious benefit to storing any unused electricity in a battery to use at night or on low-sunlight days. But how do these batteries work and what do you need to know before installing one?

How Much Does A Solar Battery Cost

A solar battery typically costs £4,500, though the exact amount depends on its size, its brand, and the materials its made from.

Prices vary, of course, but the overwhelming majority of people fall into the same range, with 80% of battery owners paying between £2,500 and £6,000, according to a Which? survey.

Batteries also require little to no maintenance, so your initial outlay will probably be the last time you have to spend money on them.

Youll usually pay 10% to 20% more for a solar battery that can take you completely off-grid, which works out around £5,000, on average.

So if the idea of living independently is attractive to you, this is an excellent, gloriously eco-friendly way to do it.

How Will Electric Cars Affect The Future Of Solar Batteries

Home solar batteries will become cheaper as we see an increase in the use of electric cars.

Some car manufacturers, such as Nissan, have collaborated with battery suppliers to use the car batteries after they are no longer good enough for the cars.

The largest home battery systems are around 14kWh but cars start at around 28kWh and can be up to 100kWh plus.

When the capacity drops the batteries are then used to make home battery systems and this second life battery will be significantly more cost effective when the turnover in cars increases.

Solar Prevents Power Outages

What Type Of Solar Battery Should I Get?

Youre generating your own energy, so the lights should stay on during a power outage, right?

Unfortunately, thats not the case with grid-tied solar systems. Although the power originates from your panels, it is still stored in the public utility grid.

When the grid power goes out, so does yours, because theres no infrastructure to feed that power to your property.

The remedy for this is a grid-tied system with battery backup. When the powers on, it functions like a normal grid-tied system. During an outage, a small backup battery bank kicks in to keep the lights on.

It costs a bit more, but the peace of mind is invaluable, especially if you live somewhere with extreme weather conditions or unreliable power from the grid.

Am I Eligible For The Federal Solar Tax Credit

Any taxpayer who pays for a solar panel installation can claim the solar tax credit, as long as they have tax liability in the year of installation. You must be the owner of the solar panel system in order to qualify for the tax credit, meaning if you lease your system you are not eligible.

When leasing a system, the solar company will get the tax credit instead of you. We recommend you buy your system outright if you can afford to. The money you save in the long run is more. Leasing also makes it harder to sell your home, as buyers don’t want to take over a 25-year lease.

Before You Install A Home

Consider whether youre generating enough electricity that you don’t use to make it worth adding energy storage to an existing solar panel system.

If youre looking to protect yourself against power cuts with a home battery, as 4% of Which? members with solar panels who own or would consider a battery system told us they are, not all systems are suitable.

Get quotes from several installers on cost of installation and estimated savings. Ask them to explain their calculations to you and question anything youre not sure about.

Check that your installer is signed up to the Renewable Energy Consumer Code , which now covers storage. This means theyre signed up to a high standard of conduct, including providing good information about your installation. You also have access to RECCs complaints process if something goes wrong.

is developing certification for battery storage systems. It says this will ensure consumer protection.

Are Solar Batteries Safe

On rare occasions, lithium-based batteries can catch on fire. Because lithium batteries store so much energy, these fires can be extremely energetic and difficult to extinguish.

Sounds scary? If youre a homeowner, you shouldnt worry about this. Solar batteries like the Powerwall have intelligent software and hardware that prevents them from being overcharged and overheated. Also, these fires typically occur when the battery is physically damaged, such as being crushed or penetrated. Home solar batteries have hard cases and are mounted in an out-of-the-way location, keeping them nice and safe.

How Solar Batteries Work

Should I buy a Home Storage Battery for my solar PV system?

Solar batteries store the extra solar energy your panels produce that you don’t immediately use, so you can draw from it later.

See, solar panels produce the most electricity during the middle of the day, which also happens to be the time when your home uses the least amount of electricity. With a regular grid-tied solar system, that excess solar energy gets sent back to the utility grid.

When solar panels are paired with a home battery, however, that excess electricity goes into the battery instead of going to the grid. Then, when the sun goes down and your panels arent producing electricity anymore, you can use the energy you have stored in your battery – instead of paying for electricity from the utility.

This means you get to power your home with all of the clean, renewable solar power your solar panels produce no matter what time of day it is.

What Are The Best Batteries For Solar Storage

The best home battery for solar storage will depend greatly on what you want to do with the energy.

Perhaps your car is the best storage battery as the energy goes directly to the car battery from the solar array and you will not need to redeploy it elsewhere.

It is almost more important to look at the energy management capabilities of the home battery system and make sure that it matches your requirements.

How Does The Solar Tax Credit Work In 2021

The federal solar tax credit is the most popular financial incentive for homeowners looking to go solar. The 26% tax credit is a dollar-for-dollar reduction of the income tax you owe. Many homeowners think they are not eligible for the solar tax credit because they dont have an additional tax bill at the end of the year.

This is not the case, the federal solar tax credit can get back a refund of the taxes you have already paid out of your weekly or fortnightly paycheck. Also, if you dont have enough tax liability to claim the credit in that year, you can roll over the rest of your credits to future years.

Are There Any Rebates For Battery Backups

Why should I get solar panels for my home?

Youll be happy to know that there are a number of rebates available across the United States for renewable energy. Solar Battery Backups fall in this category. These rebates include federal tax credits , as well as some state and utility rebates.

While each has their own requirements, here is a brief description of them:

Federal Tax Credit For Solar Batteries

The federal solar tax credit is the most significant solar tax incentive in the US. Currently worth 26% in 2020, for batteries to be eligible the solar battery must be charged 75% or more by the solar panels. When calculating your battery tax credit, you multiply the percentage of battery charge supplied by solar, e.g. 80% by the 26% from the tax credit . This will allow the cost of your batteries to be claimed as a deduction to your federal tax liability.

California: Self-Generation Incentive Program

The California Public Utilities Commission, operates this program. It provides incentives on distributed energy resources to businesses and homeowners. It also covers fuel cells, wind turbines, and waste-to-heat.

Massachusetts: Solar Massachusetts Renewable Target Program

How Much Does It Cost To Add A Solar Battery To Your Home

Your solar battery cost depends on a variety of factors, including power rating, depth of discharge capability, round-trip efficiency, and the warranty that’s provided, but the biggest factor is the capacity of the battery. Typically the bigger the solar battery, the higher the cost.

A good rule-of-thumb for solar battery cost is that the cost per kilowatt-hour ranges from $400 to $750. Therefore, a typical home solar battery is going to cost between $10,000 and $20,000, including installation costs.

If you need multiple batteries, the cost for the entire battery backup system might be higher, but Palmetto can make a recommendation for how many batteries you would need, based on your homes typical energy use, and provide you with various options for how much solar battery storage you might want to include in your overall system design. If youre looking for an answer to, How much is a solar backup battery? then thats a good place to start.

Is The Tesla Powerwall Worth It

In our opinion, the Powerwall is a great battery. It has advanced features and impressive technical specs for a decent price.

But is the Powerwall worth it? To be honest, not really. The battery that we put at the top of our list is the LG Chem Prime because of its high power capacity, operating modes, and low price.

Unfortunately, Teslas decision to only sell Powerwalls with new solar panel installations makes it much harder for homeowners to get their hands on one, which is a huge letdown for a few reasons.

First, homeowners who already have solar panels and want to install a battery can no longer get a Powerwall right from Tesla, and instead have to search for a certified installer willing to sell a Powerwall to them. Plus, they then might have to deal with a substantial wait time.

Second, when it comes to solar installations, Tesla is notorious for having poor after-sales service. So now, if homeowners want a Tesla Powerwall, they run the risk of dealing with the subpar customer service that Tesla has been known for. And thats not just when youre getting the system installed, its a problem youll have to deal with over the lifetime of the solar panels – a whole 25 years!

With all that being said, if you dont already have solar, are willing to risk getting poor customer service over the 25 years that you have Tesla panels on your roof, or are okay with potentially months or year-long wait times to get a battery installed, then a Tesla Powerwall is right for you.

Was The Federal Solar Tax Credit Extended

Yes, the solar investment tax credit was extended at the 26% rate for an additional 2 years. It was originally going to drop to 22% in 2021, but now with the new legislation being passed, it will remain at the 26% rate until the end of 2022.

This is great news for homeowners thinking about solar, as the tax credit was voted as the single most important financial incentive in the largest home solar survey.

Electricity During Storms Severe Weather And Other Power Outages

Solar Batteries: 4 Reasons to Buy Battery Storage

The grid power supply can be affected by seasonal storms and other severe weather conditions that lead to power outages, sometimes extending for hours or even days. A good example is the huge winter storm that hit Texas in mid-February 2021, causing power outages for at least 4.5 million customers. To add insult to injury, some Texans were even stuck with huge utility bills as some electricity rates skyrocketed more than 7,000% in a matter of days.

Another example of severe weather leading to large-scale power outages was the massive 2019 wildfires in California. More than 2 million customers were left without power after the utilities turned off the grid to prevent high winds from knocking down power lines and starting even more wildfires.

Having solar battery storage added to your solar power system can save you the stress of having to experience similar occurrences in the future, as you can use the power thats stored in your battery, even if the rest of the grid is experiencing a blackout. With climate change causing more severe weather and larger and even more destructive storms, its a safe bet that large-scale blackouts will continue to be an issue in the coming years.

Solar Batteries Allow You To Use Your Solar Energy At Night

One significant benefit of installing a solar battery is that you can now utilise your solar energy at night!

The excess solar energy that is not used up during the day is captured and stored in your battery for times when your solar input isnt great, like at night.

Another benefit of the battery is that you can opt for blackout protection! If your street goes dark having a battery that supports blackout protection means that you can still run your home as normal.

There are two types of blackout protection:

  • Whole-of-house protection.
  • Selected appliance protection.

Do You Have Lithium Batteries

If you do, then ignore the 50% rule. The usable capacity of most lithium batteries is between 80 and 100 percent of the batterys rated amp hours. This means you can repeatedly use 80 to 100 percent of the battery capacity without damaging the battery .

A simple way to estimate how much solar power youll need is to apply the 1 Watt to per Amp Hour rule. Simply put, your maximum solar output should equal your battery capacity .

EXAMPLE: A 400 Amp Hour battery bank will need roughly 400 Watts of solar. This is just a rough measure to get you in the ball park. You should also take into account the efficiency of your panels, amount of sun in your area, cable size/length, and power loss between your solar panels and batteries . I recommend adding at least 20 percent to the solar estimate to account for these factors.

How Much Energy Can Be Stored In A Solar Battery

The energy that a solar battery can store is measured in kilowatt-hours , and different manufacturers produce batteries that can hold varying amounts of power. For example, the Sonnen Eco is available in capacities that range from 5 kWh all the way up to 20 kWh in a single battery.

In addition, most solar batteries can be linked together or installed in an interconnected design to offer a larger combined storage capacity if your needs are higher than what a single battery can provide.

Solar Power On A Common Roof

Why should I get a solar battery storage system at home ...

Households that have an owners corporation such as unit blocks and even townhouses are often not permitted to use a common roof area for a solar power system. Before getting a quote for solar power, it is important to contact your strata management to see if you are allowed to install solar power even if it is not a shared roof that you are planning to use for the installation.

We also find some new developments have rules restricting the installation of panels on the street-facing roof. This might be a complete show stopper, or it may mean our install planners will need to design an array that uses a roof section along the side of your house, typically facing west.
