Pro Tip: Ordering Tesla Solar? Save $300+ by using a Tesla referral link from another Tesla owner.

Does Tesla Offer Discounts on Solar Products?

Before the detailed breakdown of each items cost, let’s cover any potential discounts.

Tesla solar panels are already the lowest price solar panels on the market, but are there any other ways to save money when ordering?

In short, the only way to get a discount on Tesla solar panels is by using an existing Tesla owners “referral link” when ordering your Tesla solar panels.

Tesla has did this same “referral program” concept with it’s vehicles and essentially it allows new customers to get a discount on their purchase by using an existing customers personal referral link.

In regards to Tesla solar discounts, using a Tesla referral link when ordering will save you $300 off solar panels or $500 off solar roof.

The referral discounts are typically only available for a limited time before Tesla stops offering the discount, so take advantage of the savings while you can.

A Detailed Cost Analysis of Tesla Powerwall

When purchasing a Tesla Powerwall, there are many variables that may affect the initial pricing and long-term costs of buying and installing a Powerwall. One of the most important things to consider is that Powerwalls are not available for individual sale. You would need to buy Tesla solar panels to be eligible to buy a Powerwall.

Some states have implemented state-wide incentive and rebate programs for owners of technology like the Tesla Powerwall.

In other states like Massachusetts, they are only at the beginning stages of incentivizing technology that operates in conjunction with clean and renewable energy, such as the Powerwall. This reduces the potential economic benefits of purchasing the Powerwall in some states compared to others.

Here is a run-down of the economic variables that determine the upfront costs of the Tesla Powerwall and the potential savings you can expect to see:

  • Powerwall battery costs
  • Solar panel costs
  • Back-pp Gateway 2 energy management system
  • Powerwall installation costs
  • Federal tax credits
  • California SGIP program
  • Green Mountain’s Bring Your Own Device program
  • State, local, and utility incentives for Tesla Powerwalls

The best place to start before exploring available rebate and incentive programs that vary between states, you should be well-informed about the upfront costs of the Powerwall. These upfront costs factor in the cost of the Powerwall battery unit and Tesla’s energy management system called Gateway.

Powerwall Battery Costs

As previously stated, the Powerwall Battery unit alone costs $7,500. Of that $7,500, the Powerwall makes up $7,000 of the total cost, and the remaining $500 covers the hardware and associated components. This is an upfront cost you can expect to pay when ordering the Tesla Powerwall.

The Powerwall battery functions as a secondary energy source for your home. When your home is off the grid during a power outage, the Powerwall powers your home using stored energy from your solar panels or Solar Roof if you have one. This makes Powerwalls silent compared to gas-powered electrical systems.

Depending on the size of your home and amount of energy consumption, purchasing more than one Powerwall may be necessary to ensure your home has electricity during a power outage. To incentivize the purchase of multiple Powerwalls, Tesla offers increasing discounts for every additional Powerwall you buy.

The following table lists the costs for one or more Powerwalls taken from the official Tesla website and calculations based on the average household energy consumption of 30 kWh/day.

Number of PowerwallsCostHours of Electricity
1$12,50012
2$19,00018
3$26,00024
4$33,00030
5$41,00036

These prices do not include the cost of solar panels, federal rebates, or money saved from state incentive programs. With the purchase of more solar panels and Powerwalls, the cost of each Powerwall decreases and is more heavily discounted.

Solar Panel Costs

In recent years, Tesla made Powerwalls unavailable for individual sale and only available with the purchase of Tesla solar panels. This changed the price structuring of Powerwalls since you save more now on both solar panels and Powerwalls when purchased together.

Depending on the energy needs of your home, you may or may not benefit from installing more solar panels to generate enough energy. The amount of energy generated by your solar panels will vary depending on the climate and available sunlight in your area.

Solar PanelsDaily Energy ProductionCostMonthly Electricity Savings
4.08 kW13-20 kWh$6,491$90
8.16 kW27-39 kWh$12,981$180
12.24 kW40-59 kWh$19,472$269
16.32 kW54-78 kWh$25,963$359

As the table shows, the initial costs of the solar panels are higher when you install more, but you also save more money each month on your electric bill. This trade-off between short-term expenses and long-term savings is important when purchasing a Powerwall with solar panels.

Here is another way to think about the relationship between short-term costs and long-term savings: the more money you spend on solar panels now means more money saved on electricity each month. And with more money saved each month, the quicker your initial investment in solar panels will pay itself off over time.

Back-Up Gateway 2 Energy Management System

Gateway is an energy management system installed with every Powerwall that manages the connection between your Gateway and the grid. During power outages, the backup Gateway disconnects your home from the grid and connects to the Powerwall to act as the primary power source.

The backup Gateway 2 is $1,000 and is included in the costs associated with the Powerwall. The installation of the Gateway is also included in the installation costs of the Powerwall.

Considering the important function, the Gateway serves as a mediator between the Powerwall and the grid. This makes Gateways a necessary expense and component in every Powerwall setup.

Federal Tax Credits

Regardless of the state, you live in, purchasing a Tesla Powerwall makes you eligible for a 26 percent federal tax credit. This will save you money by reducing the amount of income tax you owe to federal governments. These federal tax credits are given to incentivize green technology.

When you are ordering your Powerwall on the Tesla website, the federal tax credits will be factored into the final price listed. This ensures that customers are aware of the tax credits they will receive after completing their purchase and give a more accurate estimate of the real price of their Tesla products.

California’s Self Generation Incentive Program

States like California take even more initiative to promote green energy and technology compared to other states. The Self Generation Incentive Program (SGIP) provides a sizable rebate for qualifying distributed energy systems, including advanced energy storage systems like the Tesla Powerwall.

California greatly prioritizes clean and renewable energy in its policies—offering more incentives and tax breaks to people that invest in green technology. In other states, you may only find cash rebates without any comprehensive green-energy initiatives and programs.

According to the California Public Utilities Commission, residential and non-residential facilities with installed energy storage systems that could function during a power outage are eligible for a rebate.

For business owners, you can also take advantage of this rebate for your company facilities if you choose to install a Powerwall. This shows how far-reaching the Self Generation Incentive Program is in California. Technology like the Powerwall is heavily incentivized to spur the transition to greener technologies.

SGIP Application

To receive the SGIP cash rebate, you need to apply for SGIP online. Due to the high volume of applicants, the funding of this program is dependent on the number of applications and what step in the SGIP budget you are in. You can view the SGIP budget here to view the funding for each step.

Here is the list of steps you must go through before receiving your SGIP cash rebates:

  • Complete your Powerwall order and wait for confirmation. Afterward, a certified installer or Tesla employee must file the SGIP paperwork on your behalf to reserve a part of the funding.
  • The installation of your Powerwall will finish. Once Tesla gets approval from your utility company to operate your electrical system, then your Powerwall will be commissioned and fully operational.
  • The last portion of the SGIP paperwork will be filed by your certified installer, and an SGIP administrator will check your system to ensure it is fully functioning.
  • The cash rebate will be sent to you.

To avoid your cash rebate being denied to you, make sure the installer of your Powerwall is certified. If not, then you will not receive any cash rebate through the SGIP program.

Green Mountain’s Bring Your Own Device Program

In coordination with Renewable Energy Vermont, Green Mountain gives qualified battery owner’s cash handouts after enrolling in the BYOD program. Tesla Powerwalls are eligible for this program along with other clean energy storage devices. This upfront payment amount is dependent on the amount of energy the batteries store.

Here is how the payment system works:

  • $850/kW of storage for three-hour discharge
  • $950/kW of storage for four-hour discharge
  • An extra $150 per kW when retrofitting existing solar-powered systems that help put less strain on the power grid

This program is available to residents and small businesses wishing to install a Powerwall battery to their home or business sites. Vermont’s green energy initiatives like the BYOD program help to make electricity less expensive for everyone using the grid while spurring a transition toward cleaner energy sources.

To enroll a Powerwall into the BYOD program, you will need to visit the official Green Mountain Power website and click on “enroll now.” Afterward, you will need to provide some information about yourself and the battery you are trying to enroll in the program.

State, Local, and Utility Incentives

The state where you live and the utility companies you have access to are both contributing factors that determine your eligibility for cashback rebates and incentive programs. States like California are paving the way for green technologies and infrastructure supported by environmental policies that promote clean energy use.

Since Tesla Powerwalls are classified as energy storage systems, homeowners in California are eligible for a cash rebate through the Self Generation Incentive program. Similarly, the state of Vermont gives $850 payments to owners of Powerwall batteries after enrolling in the Bring Your Own Device (BYOD) program.

Although Vermont and California have some of the best state and utility incentives, many other states give tax credits, exemptions, and other benefits to owners of Powerwalls.
