Ditching your gas-guzzler for an electrical car (EV) is an effective way to decrease the fee and emissions of getting from A to B. However charging an EV with photo voltaic panels is a next-level life hack for saving cash, bypassing public charging, and all however eliminating your carbon footprint.

And with the Inflation Discount Act of 2022 creating substantial incentives for EVs, photo voltaic, and battery, there’s by no means been a greater time to arrange a solar energy charging station proper in your individual dwelling.

Whether or not you have already got an EV, photo voltaic panels, or neither, we’ll focus on your choices for charging an EV with photo voltaic panels.

What are the advantages of charging your EV with photo voltaic panels?

Round 80% of EV house owners have a charging station in their very own dwelling. There are three important advantages to pairing that EV charger with photo voltaic panels:

1. Decrease charging prices
2. Zero carbon emissions
3. Comfort of charging at dwelling

Let’s begin with how a lot cash it can save you by charging your EV with photo voltaic panels.

Dwelling photo voltaic is the most affordable strategy to energy a automotive

Traditionally, drivers have been on the mercy of gasoline costs and will solely management how a lot they drive and, to some extent, how gasoline environment friendly their car is. However that’s not the case. By going photo voltaic, they will management the price of the gasoline itself.

In accordance with the U.S. Division of Transportation, the common driver places on 13,476 miles per yr, or practically 37 miles per day. By charging an EV with photo voltaic panels, a Tesla Mannequin 3 driver getting 3.33 miles per kWh would spend $1,500 much less per yr in comparison with filling a gasoline automotive that will get 30 miles per gallon at round $4 per gallon.

Charging an EV with photo voltaic can also be cheaper than charging with grid power or public EV chargers.

Right here’s how a lot it prices to cost the most well-liked EV (Tesla Mannequin 3) on photo voltaic, grid, and public chargers versus fueling a comparable 30 miles per gallon combustion automotive.

Value of charging an EV with photo voltaic vs different fueling strategies

Charging methodology Mannequin 3 on dwelling photo voltaic Mannequin 3 on grid power Mannequin 3 on public charger 30 mpg combustion automotive Miles per unit of gasoline 3.33 miles per kWh 3.33 miles per kWh 3.33 miles per kWh 30 miles per gallon Distance per yr 13,476 miles 13,476 miles 13,476 miles 13,476 miles Gas per yr 4,047 kWh 4,047 kWh 4,047 kWh 450 gallons Value of gasoline per unit $0.08 per kWh $0.166 per kWh $0.40 per kWh $3.96 per gallon Complete gasoline value per yr $323.75 $671.77 $1,618.40 $1,777.04

Let’s break this down somewhat additional. Charging an EV with photo voltaic is:

• 51% cheaper than charging on grid energy
• 80% cheaper than charging on public chargers
• 81% cheaper than filling up a 30 mpg automotive at $4 per gallon

Bear in mind, these figures will fluctuate by the mannequin of automotive, distance traveled, and the price of gasoline and any given time.

Actually, the value of dwelling photo voltaic power is the one fixed. As soon as you buy and set up photo voltaic by means of photo voltaic.com, your EV charging prices are fastened at round 6 to eight cents per kWH for the lifetime of the system.

That’s not true for grid power or gasoline. Since 1990, grid power has elevated by a mean of 1.98% yearly, in response to the U.S. Power Data Administration (EIA). And over the past 87 years, the value per gallon of gasoline has elevated on common 3.89% yearly.

Right here’s how that appears over the 25 yr lifetime of a house photo voltaic system:

Over 25 years, the common driver charging an EV with photo voltaic panels will save:

• Over $14,000 by charging an EV with dwelling photo voltaic in comparison with grid power
• Practically $70,000 in comparison with fueling a gasoline automotive that will get 30 miles per gallon

In an period dominated by inflation, dwelling photo voltaic is the most effective hedge in opposition to rising power and EV charging prices.

Dwelling photo voltaic is the cleanest strategy to cost an EV

Not solely does dwelling photo voltaic repair your EV charging prices at an ultra-low charge, all of it however eliminates your driving emissions.

The basic argument in opposition to electrical car charging is that we are able to’t management the place the power comes from, and that’s true. In case your native grid or public charging stations are powered by fossil fuels, then so is your EV.

For reference, the US Power Data Administration estimates that renewables will generate 24% of electrical energy within the US in 2023. The excellent news is that your EV is able to working on clear power, and can achieve this more and more as renewables proceed to extend their share of manufacturing.

However the identical can’t be mentioned for vehicles with inner combustion engines, aka ICE automobiles. A tiger can’t change its stripes, and irrespective of how gasoline environment friendly, ICE automobiles will at all times cough out greenhouse gasoline emissions that pollute native air and contribute to local weather change.

For now, charging with dwelling photo voltaic is the one surefire strategy to cost your EV on clear power and eradicate your car emissions.

Charging your EV at house is handy

Subsequent to value (which the Inflation Discount Act will assist with), one of many greatest obstacles to EV possession is vary anxiousness. In different phrases, persons are anxious that charging stations are too few and much between.

Properly, how does having a solar energy charging station proper in your individual dwelling sound?

Think about waking up each morning to a fully-fueled car and by no means having to attend in line at a public charging or smelly gasoline station. Fairly candy set-up, proper? Now think about paying the lowest-possible worth to cost your EV by pairing it with photo voltaic.

All issues thought of, charging an EV with photo voltaic is affordable, clear, and handy. Now let’s take a look at tips on how to create this match made in renewable-energy heaven.

The best way to pair an EV with photo voltaic charging

The advantages of getting your individual solar energy EV charging station are plain. And with new incentives from the Inflation Discount Act, the price of pairing an EV with photo voltaic charging is on its approach down.

To begin saving, you’ll want three issues:

• An electrical car
• An EV charging system
• Photo voltaic panels

The order wherein you purchase EV and photo voltaic is completely as much as you (though we don’t advocate shopping for a charging system with out getting an EV first), and we’ll run by means of some widespread situations under.

First, let’s dive into the fee and incentives for every element.

Tax credit for getting an EV

President Biden signed the Inflation Discount Act (IRA) into regulation on August 16 which incorporates the Clear Car Credit score for brand new and used EVs and qualifying plug-in hybrids.

Individuals can get a $7,500 tax credit score for getting a brand new EV or a $4,000 tax credit score for getting a used EV (as much as 30% of the value).

Clear Car Credit score incentives

New EV Used EV Most incentive $7,500 $4,000 (as much as 30% of buy worth)

Higher but, the tax credit score may be transferred to the seller on the level of sale. Which means as a substitute of ready to make use of the credit score while you file your taxes, you need to use the tax credit score to scale back the acquisition worth of the EV.

The Clear Car credit score will probably be in impact for 10 years starting on January 1, 2023, however there’s a kicker: Not all EVs and patrons qualify, seek the advice of a tax skilled with questions in regards to the Clear Car tax credit score.

Let’s take a look at among the qualification necessities.

Used car eligibility

Used EVs have to be offered by a seller (no back-alley Craigslist offers) and the credit score solely applies to the primary time it’s resold, primarily based on its VIN quantity.

Earnings limits

The Clear Car credit score is designed to assist make EVs accessible to a bigger inhabitants of Individuals – not essentially to assist patrons that may already afford them. So the IRA contains earnings limits to qualify for the tax credit score.

The utmost earnings to qualify for the $7,500 new EV credit score is $150,000 per yr, or $300,000 for joint filers.

So as to qualify for the $4,000 used EV tax credit score, the utmost earnings is $75,000 per yr or $150,000 for joint filers.

Worth limits

Along with earnings limits, there are worth limits on the automobiles that qualify for the Clear Car credit score primarily based on the producer’s instructed retail worth (MSRP).

The Clear Car Credit score worth limits are:

• $80,000 for brand new SUVs, pickups, and vans
• $55,000 for brand new sedans
• $25,000 for used EVs

Once more, the purpose is to assist on a regular basis Individuals commerce of their gas-guzzlers for EVs, not reward hedge fund managers for pre-ordering Electrical Hummers.

Manufacturing necessities

Lastly, there are manufacturing necessities designed to encourage native sourcing, manufacturing, and recycling, principally for battery elements.

First, efficient instantly, the IRA requires ultimate meeting for eligible EVs to happen in North America.

Trending: The Best EV Chargers for Solar Panels

Then, starting January 1, 2023, eligible EVs will need to have 50% of battery elements made or assembled in North America. This requirement steps up every year till reaching 100% in 2029.

The IRA additionally requires {that a} sure share of battery minerals come from free commerce companions or are recycled in North America. The brink begins at 40% in 2023 and steadily will increase to 80% by 2027.

These necessities will do two issues:

1. Restrict the variety of EVs that qualify for the Clear Car credit score
2. Tremendous-charge native EV and battery manufacturing, recycling, and expertise

Which EVs qualify for the Clear Car credit score?

OK, so it’s fairly a little bit of legwork for the common American to search out out which EVs are eligible for the Clear Car credit score. Fortunately, the US Division of Power launched an inventory of automobiles with ultimate meeting in North America that needs to be eligible in 2022 till the battery necessities take impact in 2023.

The fashions marked “producer gross sales cap met” are at the moment ineligible for the tax credit score as a result of they already hit the 200,000 unit restrict for the earlier tax credit score. These fashions might develop into eligible in 2023 when this provision is lifted, offered they meet the battery and worth provisions.

This record was final up to date on August 17, 2022 and isn’t set in stone. We are going to replace it as the brand new provisions change eligibility requirements.

Checklist topic to vary because the Clear Car Credit score provisions replace.

Bear in mind, even when the car you need doesn’t qualify for a tax credit score, the common driver will nonetheless save hundreds of {dollars} per yr on gasoline alone by charging an EV at dwelling in comparison with paying for gasoline.

Establishing an EV charging system

The mixture of a photo voltaic panel system and EV charging station brings a number of advantages and offers an economical strategy to produce and make use of your photo voltaic power.

Photo voltaic inverters are an essential piece of this puzzle. Earlier than your photo voltaic power can be utilized by most of your gadgets and home equipment, it have to be transformed from direct present (DC) to alternating present (AC). That is additionally the case for fueling your electrical automotive with photo voltaic power.

The precise charging port will probably be put in and related to the inverter in order that it could possibly draw the electrical energy and ship it into the electrical automotive’s battery.

An alternative choice nevertheless, is to make use of a product like the brand new SolarEdge EV charging inverter, which pairs the charger and the inverter into one system.

How a lot does an EV charging station value?

In accordance with Carvana, Stage 1 and Stage 2 dwelling charging stations value between $1,000 and $2,000 for components and labor. Stage 3 chargers can value as much as $50,000, however they work solely with sure EVs. Most EV drivers will persist with Stage 1 and a pair of chargers.

Sadly, the IRA doesn’t have particular incentives for EV chargers. But it surely does provide incentives for upgrading your wiring and electrical panel, which can be needed when including a charging station.

Even so, by charging an EV with photo voltaic panels as a substitute of grid power the common driver will recoup that value of a typical Stage 1 or 2 charger inside two to 6 years.

Not a foul deal for by no means having to go to a gasoline station or public charger once more!

Including photo voltaic to cost your EV

To finish the EV photo voltaic charging trifecta you’re going to wish – you guessed it – photo voltaic panels.

Whether or not you have already got a house photo voltaic system or not, you’ll nearly actually want so as to add some panels to energy your EV – it’s only a matter of what number of. The excellent news is that the IRA elevated the photo voltaic tax credit score to 30% for the subsequent 10 years, which places a considerable dent in the fee.

Let’s undergo two widespread EV-solar situations.

Situation 1: Getting an EV earlier than you have got photo voltaic

In case you get an EV earlier than you have got photo voltaic, nice! The next step is to put in an EV charging station so you may cost at dwelling with grid power (the second least expensive choice to dwelling photo voltaic).

On this situation, it’s really useful to take a number of months to ascertain your EV battery utilization and its impact in your power invoice. Having a strong set of knowledge will assist photo voltaic installers make a exact calculation of how a lot photo voltaic you have to offset your electrical energy utilization.

When you’ve bought a baseline and also you’re prepared to chop your EV charging invoice in half, head to photo voltaic.com to get binding quotes on a photo voltaic system.

Situation 2: Getting an EV when you have already got photo voltaic

If you have already got photo voltaic earlier than you get an EV, nice! Just like the earlier situation, the next step is to get an EV charging station so you may cost at dwelling with photo voltaic power.

What you’ll probably discover is that till you add panels to account in your EV utilization, your photo voltaic system received’t fully offset your electrical energy utilization, and it’s possible you’ll find yourself with a electrical energy invoice on the finish of the yr.

There’s two methods to repair this:

• Get a pair month’s price of knowledge to know precisely how a lot additional photo voltaic capability you want
• Work with a photo voltaic.com Power Advisor to estimate what number of extra panels you’ll have to offset your EV utilization

Let’s do some math to get a ballpark determine of what number of photo voltaic panels it takes to cost an EV.

What number of photo voltaic panels does it take to cost an EV?

The precise quantity of panels required to cost an EV with photo voltaic is determined by kind of panel, EV battery measurement, distance traveled, and the quantity of solar publicity. However on the whole, it takes between 5 and 12 panels to cost an EV completely on solar energy (maybe much less in the event you make money working from home).

Simply to get a ballpark, let’s use for instance the Nissan LEAF SV Plus, which has a 62 kWh battery and 215 mile vary, because it’s eligible for the $7,500 Clear Car credit score.

First, calculate output per panel

First, we have to take into account the quantity of power that a person photo voltaic panel is producing. The power manufacturing of a photo voltaic panel depends on its materials, measurement, effectivity, age, and some different components.

Assuming 5 hours of daylight a day, a typical 250 watt photo voltaic panel will produce round 37.5 kWh of AC monthly or 1.25 kWh a day. Once more, that is an estimate and plenty of components will have an effect on manufacturing.

5 hours of solar per day X 250 watt = 1,250 Watt-hours or 1.25 kWh per day

Subsequent, calculate your EV battery utilization

Now let’s calculate how a lot photo voltaic output you’ll have to cost your EV battery.

The common driver travels 37 miles per day and the LEAF will get 3.7 miles per kWh. That interprets to 10 kWh of electrical energy per day.

You may simply alter this calculation to satisfy your driving habits and EV effectivity.

37 miles per day / 3.7 miles per kWh = 10 kWh of electrical energy per day

Lastly, divide EV utilization by photo voltaic panel output

If one 250 watt photo voltaic panel can produce roughly 1.25 kWh a day of AC electrical energy, and also you want 10 kWh of electrical energy per day, which means you would wish eight 250 watt panels to cost your Nissan LEAF EV completely on solar energy.

10 kWh of EV utilization / 1.25 kWh of manufacturing per panel = Eight 250-watt panels

In case you upgraded to premium 400-watt photo voltaic panels that produce 2 kWh per day, you’d solely want 5 panels on this situation. Then again, in the event you’re solely getting 4 hours of solar per day, you’d want nearer to 12 250-watt panels to cost your EV.

The situations are infinite and we’ll admit that the mathematics will get somewhat dense. In case you want extra readability by yourself scenario, it’s greatest to talk with an power advisor to debate your particular wants.

Ought to I cost my EV with photo voltaic panels?

You must cost your EV with photo voltaic panels solely if you need the most affordable, cleanest, and most handy driving expertise attainable.

In different phrases… sure.

The plain hurdle is upfront value for each EVs and photo voltaic panels. Nevertheless, the IRA created beefed-up incentives for each issues, together with a $7,500 tax credit score for brand new EVs and 30% tax credit score for photo voltaic and battery, which can assist soften the blow.

Right here’s the opposite approach to take a look at it: Charging your EV with photo voltaic prices about 50% lower than charging with grid energy and no less than 75% lower than public charging or gasoline. All you’re doing is shopping for 25+ years’ price of gasoline without delay for a major low cost – similar to shopping for bulk at Costco.

Photo voltaic panels are an economical strategy to gasoline your electrical automotive and will require wherever from 5 to 12 photo voltaic panels. You should utilize the averages above as a benchmark when doing your individual evaluation, and in the event you ever need assistance don’t hesitate to speak with considered one of our power advisors right this moment!
