What Does a Second Trump Presidency Mean For Rooftop Solar?

By Federal Solar Tax Credit, Solar Rebates & Incentives No Comments

On November 5, America elected Donald Trump as the 47th President of the United States. Perhaps more importantly for shaping policy, the GOP now controls the Senate and, as of writing this article, appears to also control the House. This means the GOP will have a relatively unimpeded path to implement policy to support their vision of America.

What does this mean for the solar industry? A lot is unknown. There is conflict between public statements and published policy objectives, as well as some interparty disagreement about how to handle policy that supports renewables.

How political is solar actually?

While solar is often seen as a deeply partisan issue, there are several examples of lawmakers — even Trump himself — breaking from traditional party lines to help or hurt the solar industry.

The Federal Investment Tax Credit (ITC) is a 30% tax credit against eligible costs of solar installations and the largest single economic enabler for the residential solar industry as it reduces costs for homeowners. The ITC was originally passed as federal policy in 2005 and has been renewed several times since then. During his first term, Donald Trump actually extended the ITC for a year as part of a tax extenders package at the end of 2020 when the nation was dealing with COVID.

On a State level, we’ve seen negative net metering policies take effect in blue California while red Florida extended their current version of net metering in a huge win for rooftop solar. While these policy changes were enacted for two entirely different reasons in two very different markets, it’s important to contextualize that solar shouldn’t simply be painted with a broad brush as being supported by liberal policies in liberal areas. At its core solar is an enabler of conservative ideals such as self-sufficiency, market choice, and domestic sourcing

Weighing policy change risks for solar

Although there have been several public comments about repealing the Inflation Reduction Act (IRA) in its entirety (the IRA was the sweeping policy passed in 2022 that preserved and extended the ITC), which would include the elimination of the ITC, the assumed reality is the GOP will take a scalpel to the policy and cut out parts it doesn’t like.

The ITC will likely be preserved through at least 2025 — although it may start to step down prior to its current 2030 date. There will, however, be tax code changes. So even if the tax credit remains the efficiency and ability to monetize it may become more challenging.

Trump is a big proponent of tariffs so it’s highly likely the cost of components required to install solar will go up. Although there have been significant efforts in reshoring manufacturing since the passage of the IRA, a lot of sub-components are still imported which will raise costs incrementally. And, with the precarious nature of IRA policy it’s not likely we’ll see new investments until there’s policy certainty.

So, is now a good time to go solar?

If you’ve been on the fence about going solar, today is unquestionably a great day to move forward with the project. Interest rates are .75 basis points lower than their high and, given presumed upcoming tax and policy changes, the Fed may hold off on interest rate drops for some time.

The ITC is here and can be monetized. It’s a sure thing that will not be getting more valuable over the next four years.

Component and installation costs are at an all-time low. Those will undoubtedly start increasing rapidly as companies pay tariffs or lose manufacturing subsidies.

 

 

What should I consider about going solar today vs pre-election?

The recommendations for homeowners remain unchanged:

  • Work with qualified local contractors that can weather a storm
  • Select quality components from well-capitalized manufacturers
  • And, given the risks facing Chinese companies, it should be suggested you steer clear of proposals that contain components from Chinese-owned companies as they may not be able to support a warranty claim in a few years.

No one knows how the next four years will turn out and no one knows what will happen with solar policy. But what remains certain is tomorrow the sun will rise and it will supply solar panels with limitless free, clean, power.

SCE Approves the Tesla Backup Switch Paving Way for Lower Powerwall Pricing

By Tesla Powerwall, Solar Battery No Comments

Home battery storage is crucial for backup power and maximum solar savings in California — and it just got faster and more cost-effective to install.

On October 16, Southern California Edison (SCE) became California’s third and final investor-owned utility to approve the Tesla Backup Switch. This breakthrough device streamlines backup battery installations to reduce the upfront cost and increase the number of appliances homeowners can access during a power outage.

The Tesla Backup Switch was previously approved by Pacific Gas and Electric (PG&E) and San Diego Gas and Electric (SDG&E) and has already been installed in those service areas. Reports from solar.com’s network of installers indicate that Powerwall battery systems using the new Backup Switch take one-third of the installation time and cost $3,000 to $5,000 less for the homeowner.

Let’s take a closer look at what the Tesla Backup Switch does and why it’s reducing the cost of battery storage in California.

 

 

What is the Tesla Backup Switch?

The Tesla Backup Switch is a device that connects to your electricity meter to instantly detect power outages and safely disconnect your solar + battery system from the utility grid so it can continue to power your home. This disconnect feature is required by utilities to protect line workers as they repair the grid during power outages. Without it, your solar and/or battery system will shut off when the power goes out.

Traditionally, disconnect devices (often called gateways) are mounted to the wall in a control box about the size of a pillow and are wired to an additional breaker box (known as a sub-panel). The sub-panel takes up wall space and limits the number of appliances your solar + battery system can power during an outage. Installing and wiring these additional components takes time, adding to the overall cost of the system.

Tesla Backup Switch versus Traditional Backup System comparison

How the Tesla Backup Switch does more with less

The Tesla Backup Switch streamlines the battery system by connecting to existing components in your home — namely your electric meter and your main breaker box. This has several benefits.

  1. Solar panels and Powerwall battery systems can supply power to any appliance in your home during power outages, including heating and cooling systems.
  2. Powerwall battery systems can be installed several hours faster and at a substantially lower cost
  3. The Tesla Backup Switch frees up wall space by eliminating the need for wall-mounted control boxes and sub-panels

You can see the streamlined process in the diagram below. On top, the Backup Switch attaches right to the utility meter, eliminating the wall-mounted Gateway and the additional panel box or “load center” required by the system below it. It also eliminates the wiring and conduit between these components and the hours of labor required to do it properly.

By connecting to the main breaker box, the Powerwall 3 with Backup Switch can power any system in the home, including heating and cooling (provided there is sufficient energy from the solar panels and/or battery storage). Down below, the Powerwall 3 with Backup Gateway 2 is limited to powering “essential” loads on the sub-panel. This often includes refrigeration, medical devices, and select lights, outlets, and kitchen appliances — but does not include heating and cooling.

Importance of battery storage for SCE customers

For SCE customers, battery storage does much more than provide backup power. It’s also key for maximizing your solar savings under the NEM 3.0 solar billing policy, which drastically lowered the value of selling solar electricity back to SCE.

For example, let’s say the value of your solar electricity is 10 cents per kilowatt-hour. Under NEM 3.0, you’re typically compensated at 4-5 cents per kilowatt-hour — about half of what it’s worth — when you sell your excess electricity back to the grid. And when the sun isn’t shining, you’ll end up buying electricity from SCE at around 30 cents per kilowatt hour.

With battery storage, you can store and use your own solar electricity to avoid selling low and buying high.

So, battery storage is crucial for solar savings in California and the Tesla Backup Switch is a game-changer because it lowers the overall cost of a Powerwall battery system by $3,000 to $5,000. And while Tesla is the first to offer this breakthrough technology, other manufacturers are expected to follow in early 2025, paving the way for lower battery pricing across the board.

The bottom line

The Tesla Backup Switch is a major advancement that both increases the performance and lowers the cost of Powerwall battery systems — and it’s now approved for customers of SCE, PG&E, and SDG&E.

Frequently asked questions

Is the Tesla Backup Switch approved by PG&E?

Yes, the Tesla Backup Switch is approved by all three California investor-owned utilities. This includes PG&E, SCE, and SDG&E.

What does a Tesla Backup Switch do?

The Tesla backup switch attaches to your utility meter to detect power outages and instantly disconnect your home from the grid. This allows your solar + battery system to stay active so it can power your home during power outages.

How much do I get for selling electricity back to the grid in California?

Under NEM 3.0, homeowners earn around 4 cents per kilowatt-hour on average for selling their electricity back to the grid. This is typically much lower than the cost of generating solar electricity and it is more valuable to store and use your own solar energy in home batteries.
