Do you need solar panels for tesla powerwall

It solves one of the biggest problems of sustainable energy: while solar panels are great for collecting energy during the day, they’re not so good at night – but that’s when we tend to use electricity the most.

Powerwall is a home battery that stores solar energy so you can use it day or night and self-power your home. Solar panels typically generate more clean energy than your house can immediately use. Powerwall stores that excess solar to make it available on demand, maximising your use of solar and reducing your reliance on the grid. Through the Tesla mobile app, you gain full visibility and control over your self-powered home.

The Telsa Powerwall can power an average two-bedroom home for a full day. Compact and simple to install, Powerwall 2 is a completely automated system that requires no maintenance.

The Powerwall 2.0 has more than twice the energy storage capacity of the original version with 13.5 kWh capacity. Over double the capacity means double the ability to keep your home humming with guilt-free electric power.

The Tesla Powerwall 2 is a revolutionary home battery. It can be installed with your solar panel system to self-power your home, day or night.

What is a Tesla Powerwall?

When you go solar, a solar battery storage system is the only way to keep your home powered through outages and helps reduce your reliance on the grid. The second generation Tesla residential battery storage system, the Powerwall 2, delivers up to twice the energy density of the original. In this article, we answer the question:

Is the Tesla Powerwall 2 battery worth it?

Let’s take a look at why the Tesla Powerwall 2 battery is worth the investment for a lot of homeowners.

Let’s start with the factors involved in worth. Adding a battery to your solar PV system will increase the initial cost; however, if it’s a smart investment in your home energy goals, solar battery storage can be worth the extra cost. And don’t forget incentives that can make the decision to add a solar battery a no-brainer.

Here’s where to start.

1. Evaluate Your Home Energy Goals

First ask yourself: what are your most important reasons for adding solar energy to your home?

• Saving money on your electric bill?
• Reducing your carbon footprint?
• Peace of mind in outages, blackouts and natural disasters?

If you answered yes to any of these, then you could be in the market for a Tesla Powerwall battery.

2. Calculate Actual Price Including Incentives

The price tag on the Powerwall can seem hefty at initial glance, but in order to know your actual cost, you’ll have to evaluate all the factors with a qualified Tesla installer. That way you’ll know exactly how much you’re going to be spending (including equipment, installation, permits) as well as all the incentives available to you.

How Much is a Tesla Powerwall?

The Powerwall is eligible for the 30% federal solar tax credit as well as several other state incentives, depending on your state and region*. Installing a Powerwall and a solar system also makes you eligible for net metering programs in states that offer this. This allows you to sell back unused energy to your utility company, and when you have a home solar battery you’ll have the option of storing that extra energy for future use (especially useful during peak energy use times when prices are higher.) What this all means is dramatically reduced electricity bill, or in some cases a negative balance that carries you through the high use times of the year.

Reasons You’ll Need a Solar Battery

The main reason solar batteries like the Tesla Powerwall have grown in popularity is: energy independence. For those looking for complete peace of mind in outages, blackouts and natural disasters, the Tesla Powerwall is a necessary investment.

  

Energy Independence

Let’s talk a bit about what energy independence means. Your home is hooked into your utility company’s grid for power, so you’ll always have dependence on it, even when you have solar installed. (Unless you actually live off-grid meaning you are producing all of your own energy.)

And even with solar panels,  it’s not possible to have any kind of independence from the grid without a battery storage system. With a house solar battery like the Powerwall, you can stop relying so heavily on the grid with your stored excess solar energy.

Reduce Your Electric Bill

Another major reason homeowners have gone solar in the last decade is energy prices. The last decade saw a steady incline of energy prices, while typical homeowners that made the move to solar energy saw a dramatic decrease on their monthly electricity bill.

If this is part of your goal, make sure to evaluate a solar battery for your home with a professional. Why? Because during peak hours (like nighttime), energy prices generally rise, but if you’re storing excess sun power from the daytime, you’ll be good to go for the night.

Minimize your Carbon Footprint

If this is part of your goal, switching to solar panels may not be enough. Adding a solar battery like the Tesla Powerwall to your installation will give you a power up for helping out the environment.

It’s simple. The more energy you pull from the grid, the more non-renewable sources you’re consuming. Reduce that with a solar battery.

In conclusion, if you’re looking for a reliable way to reduce your electricity bills, avoid blackouts, and reduce your environmental impact, you’ll need a solar battery.

Top 4 Benefits of the Tesla Powerwall 2 Battery

1. Power through the night.

The most widely known benefit of the Tesla Powerwall is to produce all of your electricity without using energy from your local energy company. Solar panels often generate more electricity than a home can use during the day when the sun is shining. With the Powerwall, you can store that energy reserve to power your home at night or for later use, instead of letting that clean power go to waste.

Even if your solar panels are making you money with your utility company through net metering, the solar energy your panels produce is about 2-3 times more valuable than sending it to the utility company for credits. The only way your home can keep all the energy it produces is with a battery backup system like Tesla Powerwall.

2. Avoid surging electric prices.

Energy companies often raise their rates at certain times of the year and the cost of energy is constantly rising. With the Tesla Powerwall you can avoid these rates and peak charges. Even when your solar panels are not producing energy your home will still run on stored energy from the Powerwall. Check to see if your utility offers Time-of-Use rates which allows you to use less expensive solar energy you’ve already generated and stored in your Tesla Powerwall battery. Doing this will allow you to avoid electrical charges during more expensive rate periods.

3. Monitor your energy usage.

Each Powerwall installation includes a complete energy monitoring solution for your home. You can see how your home both produces and uses energy at any given time. Using the Tesla app, you can monitor your home energy system in real time.

4. Protect your home.

The most enticing benefit of the Tesla Powerwall is to protect your home when disaster hits. When your neighborhood gets hit with storms, your Powerwall will keep your home powered. In addition, your Powerwall can communicate with the National Weather Service. When you enable Storm Watch, your Powerwall can prioritize charging in anticipation of severe weather. And the Powerwall will snap on within seconds from any grid outage.

Very satisfied with our system! We will be moving soon and wanted to increase the value of our rental with the solar system. We already have a Tesla car so being able to utilize the battery to charge our cars and reduce our bills even further was a huge plus! Everyone from the instal crew to the sales team were highly professional we would definitely recommend them.

I’ve talked with several “Solar” companies over the last couple years. [ADT Solar] had all the right answers to my questions, a I asked just to see what they said because I already knew the answer. New roof in a day, panels, wiring and complete new breaker box and service in less than a week. Texas lost power all over, my lights never flickered! Couldn’t ask for better service or much better products! Thank you!
