Over the 25-year warrantied life of a solar system, that adds up to a major reduction in energy cost savings.<\/p>\n<p>Here\u2019s how that looks for a cash purchase for an average 7.6 kW system:<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter wp-image-10298 \" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/2022\/12\/nem-2-vs-nem-3-branded-1024x1024.png\" alt=\"NEM 3.0 vs grandfather into NEM 2.0\" width=\"587\" height=\"587\" \/><\/p>\n<p>So, if over $40,000 in electricity cost savings sounds worth fighting for, let\u2019s look at how to grandfather your system into NEM 2.0.<\/p>\n<p><strong>Related reading:\u00a0<\/strong><a href=\"https:\/\/www.solar.com\/learn\/5-things-to-know-in-the-final-weeks-of-nem-2-0\/\" target=\"_blank\" rel=\"noopener\">5 Things To Know in the Final Weeks of NEM 2.0<\/a><\/p>\n<h2>How to grandfather a solar system into NEM 2.0<\/h2>\n<p>There are two steps required to grandfather a solar system into NEM 2.0.<\/p>\n<ol>\n<li>Submit a solar interconnection application to your utility before April 13, 2023<\/li>\n<li>Install and receive permission to operate (PTO) within three years of submitting your interconnection application<\/li>\n<\/ol>\n<p>Now, unless you speak solar-ese, you&#8217;re probably wondering &#8220;What is an interconnection application and how do I submit one.&#8221;<\/p>\n<p>We&#8217;re so glad you asked! Let\u2019s start with a quick crash course on interconnection applications.<\/p>\n<p><strong><em>Quick Note: <\/em><\/strong><em>NEM 3.0 is not retroactive. Existing solar systems will remain under their current net metering policy for 20 years from their interconnection date.<\/em><\/p>\n<h3>What is an interconnection application?<\/h3>\n<p>According to Perry, an interconnection application is a series of documents that give your utility company information about your solar system in order to turn it on safely.<\/p>\n<p>According to the final NEM 3.0 proposal, a valid solar interconnection application includes:<\/p>\n<ul>\n<li>Complete application<\/li>\n<li>Signed contract<\/li>\n<li>Single-line diagram<\/li>\n<li>CSLB Disclosure Document<\/li>\n<li>Signed consumer protection guide<\/li>\n<li>Oversizing attestations (if applicable)<\/li>\n<\/ul>\n<p>While this list of items reads like gibberish, these are all standard documents that any reputable solar installer will be familiar with.<\/p>\n<h3>How do I submit an interconnection application?<\/h3>\n<p>Ready for the good news? <strong>Your solar company will fill out this application and submit it on your behalf.<\/strong><\/p>\n<p>In terms of grandfathering a system into NEM 2.0, the more important question is <em>when <\/em>in the solar process can you submit an interconnection application.<\/p>\n<p>\u201cGrandfathering is based on the submission date of the interconnection application, which can be done before the system is even installed,\u201d Perry said. \u201cThis step can be completed anytime after the site survey when the design is finalized.\u201d<\/p>\n<p>Typically, solar installers submit the interconnection application <em>after <\/em>the system has been installed. However, in response to NEM 3.0, many \u2013 but not all \u2013 companies are changing their operations process to submit as early as possible.<\/p>\n<p>Since solar installations typically take 3-5 months to line up, it\u2019s important to find an installer that has changed their process to submit interconnection applications early.<\/p>\n<p><a href=\"https:\/\/www.solar.com\/dashboard\">Get the solar process started today with multiple quotes from vetted network of installers<\/a><\/p>\n<h2>5 tips for grandfathering a solar system into NEM 2.0<\/h2>\n<p>There is little time to waste if you\u2019re trying to grandfather a solar system into NEM 2.0, so we rounded up some tips for getting your solar interconnection application submitted before the April 13 deadline.<\/p>\n<h3>Tip #1: Get solar quotes ASAP<\/h3>\n<p>According to Perry, the first and most important step is to get quotes from reputable solar installers \u2013 which you can do <a href=\"https:\/\/www.solar.com\/dashboard\" target=\"_blank\" rel=\"noopener\">right here on solar.com<\/a>.<\/p>\n<p>Identifying, vetting, and gathering quotes with multiple solar companies takes time, but we\u2019re here to quickly do that legwork for you.<\/p>\n<p>In our guided solar process, you team up with an Energy Advisor to quickly generate dozens of quotes from vetted local installers. We\u2019ll present you with the three best and advocate for your project throughout the process.<\/p>\n<p>Every installer in our network is rigorously vetted for certifications, experience, sound financials, and excellent customer experience. In fact, we accept fewer than 30% of the companies that apply.<\/p>\n<p><a href=\"https:\/\/www.solar.com\/dashboard\">Connect with an Energy Advisor to start your solar project.<\/a><\/p>\n<h3>Tip #2: Identify installers with NEM 2.0 grandfathering processes<\/h3>\n<p>Once you\u2019ve generated quotes, Perry said it\u2019s important to narrow the list down to installers with this crucial question:<\/p>\n<p style=\"text-align: center;\"><strong><em>Is your company prepared to submit the documents needed for NEM 2 grandfathering early in the process?<\/em><\/strong><\/p>\n<p>This is important because the interconnection application step is usually done <em>after<\/em> the installation, which can take 3-5 months. But the recent NEM 3 ruling changed this process. Instead of waiting until after installation to submit the required documents for grandfathering, many companies are changing their operations process to submit as early as possible.<\/p>\n<p><strong><em>\u201cDo not assume that every solar company will be adapting to this grandfathering process,\u201d <\/em><\/strong>Perry said. \u201cI&#8217;ve already seen solar company emails to customers explaining that you must be installed to be grandfathered.\u201d<\/p>\n<h3><img loading=\"lazy\" class=\"aligncenter wp-image-10452 size-full\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/2022\/12\/NEM-2.0-grandfather-process.png\" alt=\"NEM 2.0 grandfather process\" width=\"1024\" height=\"768\" \/><\/h3>\n<h3>Tip #3: Double-check the information on your contract<\/h3>\n<p>Once you\u2019ve selected an installer and designed a system, the next thing you can do is make sure the information in your contract is 100% accurate. The contract is a crucial part of the interconnection agreement and one of the only things you can control.<\/p>\n<p><strong><em>\u201cDouble-check that your name is spelled and formatted identically to how your utility has it on your electric bill,\u201d<\/em><\/strong> Perry said. \u201cEverything else on the interconnection application is your installer&#8217;s responsibility.\u201d<\/p>\n<p>According to the final NEM 3.0 proposal, grandfathering into NEM 2.0 requires submitting an interconnection application \u201cfree of major deficiencies\u201d which is, frankly, a meaningless term. The CPUC and investor-owned utilities have not clarified what constitutes a &#8220;major deficiency.&#8221;<\/p>\n<p>So, it\u2019s important to double-check your contract and submit your application as early as possible.<\/p>\n<p>\u201cThe earlier you start the process, the more time there is to catch deficiencies and get them corrected before the April 13th deadline,\u201d Perry said.<\/p>\n<h3>Tip #4: Request and save emails from your utility<\/h3>\n<p>Grandfathering into NEM 2.0 is based on the submission date of the required documents, so it\u2019s crucial to keep a record of when your interconnection application was submitted.<\/p>\n<p>Your utility will send your solar company with one of three phrases to confirm submission:<\/p>\n<ul>\n<li>&#8220;Sent for review&#8221; (PG&amp;E)<\/li>\n<li>&#8220;Deemed valid&#8221; (SCE)<\/li>\n<li>&#8220;Pending AHJ&#8221; (SDG&amp;E)<\/li>\n<\/ul>\n<p>\u201cI would request my solar company to forward me the email confirming receipt of the documents as proof of grandfathering,\u201d Perry said.<\/p>\n<h3>Tip #5: Be quick to pivot<\/h3>\n<p>Perry\u2019s final tip is a simple one: <em><strong>If your installer can\u2019t grandfather your system into NEM 2.0, g<\/strong><strong>et a new one! <\/strong><\/em><\/p>\n<p>\u201cThere is no time to be loyal to an installer being slow or difficult to work with when time is short and you need to be grandfathered to lock in your solar benefits,\u201d Perry said. \u201cIf your installer is not communicating about the hold-up, I would send them an email saying you are canceling your contract, then move on to another company.\u201d<\/p>\n<p>Beginning in January, you should be able to get emailed proof that you have been grandfathered within 2-3 weeks of signing the contract, Perry added.<\/p>\n<h2>The bottom line<\/h2>\n<p>With NEM 3.0 approved, customers of California\u2019s investor-owned utilities \u2013 PG&amp;E, SCE, and SDG&amp;E \u2013 have a brief window to grandfather a solar system under the much more favorable NEM 2.0.<\/p>\n<p>In order to remain under NEM 2.0,\u00a0 you must submit a valid solar interconnection application before NEM 3.0 takes effect on April 13, 2023.<\/p>\n<p><strong>The keys to grandfathering a solar system into NEM 2.0 are:<\/strong><\/p>\n<ul>\n<li>Get solar quotes from reputable installers as soon as possible<\/li>\n<li>Choose an installer that has adapted their process to submit interconnection applications as early as possible<\/li>\n<li>Match the name on your solar contract <em>exactly <\/em>how it shows up on your utility electricity bill<\/li>\n<li>Request and save the confirmation emails the utility sends to your installer<\/li>\n<\/ul>\n<p>There is no time to waste. <a href=\"https:\/\/www.solar.com\/dashboard\">Get started with multiple solar quotes today!<\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Update: NEM 3.0 took effect on April 15, 2023.
