There are many reasons to install solar power. Solar energy can help reduce your current electric bill, contribute to energy independence, and help save the environment. With all of the current solar rebates, solar incentives and solar tax credits available to the consumer, installing solar panels today now makes more sense than ever.
Yes and no. Yes in that different roofing materials require different methodologies which can impact the systems installation costs. Never allow inexperienced contractors to penetrate a flat roof, only experienced professionals should ever work with these difficult roofs. If your roof will need to be replaced during the next ten years we recommend that you replace it before having your systems installed. Some roofs are more costly to install on than others – flat, tile, and wood shake are more difficult whereas standing seam metal and composite shingle are easier. Many installers, including Sunergy, will not install on wood shake or tile roofs that do not have a solid decking underneath, otherwise called spaced sheathing or skipped decking.
Tesla Powerwall systems that are connected to a solar system are eligible for the 30% Federal Solar Investment Tax Credit. The system must be installed by the end of 2032 to qualify and by the end of 2033 to qualify for the reduced 26% Investment Tax Credit.
Battery backup systems are exempt for all sales taxes. Visit our incentives page for more detailed information.
Now’s a great time to lock in your energy rate before it rises again and the incentives disappear.
We’re seriously not trying to dodge this question, but it really is different on a site-to-site basis and from a personal preference. For most systems, we install 1 or 2 powerwalls. The total number is a personal choice depending on how much power you want or need to store and what types of devices you hope to switch on during a grid outage. Each of our systems are fully customized to maximize the homeowner’s financial benefit and to reach their goals. To get a full picture of how many powerwalls you might need, we would need to have an in-depth conversation about your objectives and review your average consumption history.
It’s all about the give and take when it comes to planning out your home battery storage solution. When designing your energy storage system, it is essential to find a balance between the total capacity of the Powerwall(s) with the demand of everything you need to power up. Each Powerwall can deliver up to 21 amps, and up to 6 Powerwalls can be stacked together. However, even if there is enough amperage to cover all of your loads, we need to consider the pace of how quickly electricity will be drawn to maximize the effectiveness of your back-up system.
A common misconception is that your solar output will recharge your battery at the same rate you’re using it. This depends greatly on uncontrollable factors like weather and user consumption habits. An easy way to look at battery storage is to think of how driving tendencies vary by operator and by vehicle. You may be a more efficient driver of your new Prius while your cousin Karen drives a 2001 Jeep Wrangler like she’s running a desert race. Similarly, Powerwall performance will be dependent on user consumption tendencies and what you are powering up. A small, highly efficient home with energy efficient appliances might power more than a larger, older home with leaky windows. By monitoring your usage and storage abilities, you’ll gain greater insight into what you can power and how quickly your Powerwall might recharge.
Ultimately, to determine what’s best for you, we need to take a look at your average historic usage and discuss what you’re looking to get out of our battery storage.
Not technically, but it’s hard to see the benefit of having battery storage that’s not connected to a solar system in Washington State. Unlike areas that have a high variation in on-peak and off-peak rates, think California, time-of-use load shifting isn’t financially rewarding in the Evergreen State. There is no need to store your unused solar energy since net metering allows you to store your excess production on the grid as a credit to use later. This is essentially a free energy storage vault.
Battery backup systems that are connected to a solar system from 2022-2032 are eligible for the 30% Federal Solar Investment Tax Credit. Don’t wait, prices for solar equipment are on the rise!
Just like any other battery storage option, a Tesla Powerwall captures and stores energy to be used by your home when needed later. What makes the Powerwall standout from other battery storage options is its ability to power larger loads and for a longer duration. This means you have the freedom to power up more of what you need without running out of storage during an outage.
