AC vs. DC Coupling: What’s the Difference, and Which One Do You Need?

If you’ve been looking into solar for your home or business, you’ve probably heard of microinverters —and for good reason. These small yet powerful devices are changing the game when it comes to solar efficiency, flexibility, and safety. Whether you're just starting your solar journey or considering an upgrade, understanding how microinverters work —and how they compare to other inverter types—is key to making a smart investment. What is a Microinverter? A microinverter is a type of solar inverter installed at the individual panel level. Its main job? Converting the direct current (DC) electricity produced by a solar panel into alternating current (AC) electricity, which powers your home. Traditional inverters—also called string inverters —convert power from a group of panels all at once. But microinverters handle this conversion for each panel independently. That independence comes with a host of benefits, which we’ll break down below. How Do Microinverters Work? Unlike string inverters that rely on centralized conversion, microinverters are mounted directly behind or near each solar panel. This panel-level control means each panel can operate at its maximum potential regardless of how the others are performing. For example, if one panel is shaded by a tree or cloud, only that panel’s production drops—not your entire system’s. This is one of the key advantages of microinverters: no single weak link brings down your entire array. Microinverters also offer real-time performance monitoring of each panel. If one is underperforming, you'll know exactly which one it is and why—making troubleshooting faster and maintenance smarter. Benefits of Microinverters ✅ Increased Energy Production Since each panel operates independently, your solar system performs more efficiently overall—especially if your roof has different angles or shading. ✅ Design Flexibility Have a roof with multiple angles or partial shading throughout the day? No problem. Microinverters let you install panels in varying orientations and configurations without impacting performance. ✅ Real-Time Monitoring Most microinverter systems include smart monitoring software, allowing you to track individual panel performance from your phone or web browser. ✅ Built-in Safety Microinverters meet rapid shutdown requirements in the U.S. under the National Electric Code (NEC). During emergencies or maintenance, microinverters can automatically and instantly shut down panel output, keeping first responders and workers safe. ✅ Easy System Expansion Need to add more panels down the line? With microinverters, expansion is a breeze. You can add more panels without needing to overhaul the existing inverter setup. Microinverters vs. String Inverters vs. Power Optimizers If you’re choosing a solar system, you’ll likely compare three main types of inverters : 🔁 String Inverters Most budget-friendly and simple to install. One or two units are wired to all the panels in your system. Downside: If one panel underperforms, the entire system’s performance drops. Scalability: Not ideal for future expansions. ⚡ Power Optimizers Work with a central inverter. Optimize energy output at the panel level like microinverters but don’t convert DC to AC onsite. Offer good performance and panel-level monitoring. More components than microinverters, which can add complexity. ⚙️ Microinverters Convert energy at each panel. Excellent for performance, monitoring, safety, and scalability. Slightly higher upfront cost but superior long-term benefits. What to Consider When Choosing Microinverters If you decide microinverters are right for you, here’s what to keep in mind when comparing models: 1. Efficiency Ratings Just like solar panels, microinverters have efficiency ratings that show how well they convert DC to usable AC power. Top-rated models like the Enphase IQ8 offer around 97% efficiency . Make sure you check weighted efficiency ratings like the California Energy Commission (CEC) score , which better reflects real-world performance. 2. System Size Compatibility Microinverters come in different sizes based on voltage. You want one that matches your solar panel’s output—too small and it’ll "clip" energy; too large and it might not be cost-effective. 3. Single-Phase vs. Three-Phase Single-phase : Common for most residential setups. Lower cost. Three-phase : More power, better for large homes or commercial properties. 4. Warranty Most premium microinverters come with a 25-year warranty , but it’s worth reading the fine print. Coverage details vary by brand. 5. Price Microinverters do cost more than string inverters up front. However, their long-term performance, safety, and expandability often make them worth the investment .

When it comes to replacing your roof, you're not just making a purchase—you're making a long-term investment in your home’s value, safety, and energy efficiency. At SunSent , we take roofing just as seriously as we take solar, because in many cases, they go hand in hand. Whether you're dealing with storm damage, planning to add solar, or simply upgrading your home's exterior, our team brings expertise that covers both the foundation of your energy savings (your roof) and the technology that helps power your future (solar panels). But what does "quality roofing" actually mean? Let’s break it down, using insight from Owens Corning , one of the leading manufacturers of premium roofing materials (and a brand we trust on our installs). Quality Roofing Starts with Materials That Last Not all shingles are created equal. Owens Corning, for example, sets rigorous standards to make sure their roofing materials meet—and often exceed—both industry expectations and customer needs. From granule adhesion (which affects both performance and safety) to tear strength and wind resistance , quality roofing materials are built to last through the seasons and protect what matters most: your home and your family. At SunSent , we only use high-performance, manufacturer-tested roofing materials, because cutting corners on your roof today means bigger problems tomorrow.

Most people only think about their roofs when it starts to rain—or worse, when it starts to leak. But the best time to detect roof problems is actually after the storm passes, especially on a clear, sunny day. The Midwest's Storm Reality Living in the Midwest means being no stranger to severe weather. From hailstorms to tornadoes, the region frequently experiences weather events that can wreak havoc on homes, especially roofs. In 2024 alone, severe convective storms, including hail and tornadoes, resulted in insured losses exceeding $58 billion in the U.S., with the Midwest bearing a significant portion of this damage . Missouri, in particular, has seen its fair share of storm-induced destruction. A notable example is the March 14–15, 2025, severe weather outbreak, which produced 14 confirmed tornadoes, including five EF-3 tornadoes. These storms caused extensive damage to homes, machine sheds, power lines, and trees across numerous communities . When the rain stops and the sun comes out, your roof is no longer under immediate stress, making it easier to spot signs of damage that could lead to future issues. Why Damage Shows After the Rain Water has a sneaky way of getting in and hiding. Once the rain stops, that trapped moisture starts to dry out—and in doing so, it often leaves behind visible signs. The sun helps reveal warped shingles, faded stains, and other indicators that might go unnoticed during the storm. What to Look For on a Sunny Day Shingle Curling or Buckling: If your shingles look lifted or wavy, moisture might have seeped underneath them. Stains on Exterior Walls or Fascia: Discoloration or streaks on the sides of your home can be signs of water running where it shouldn't. Attic Inspection: Head up to the attic and look for water stains, damp insulation, or that tell-tale musty smell. Soft Spots on the Roof: If it’s safe to do so, gently walk on your roof and feel for spongy or soft areas that might indicate rot. Sagging or Uneven Areas: These can signal water pooling and weakening the structure underneath. Moss or Algae Growth: If water stuck around too long, you might start to see green patches growing on your roof. Gutter Issues: Overflowing or clogged gutters can send water behind siding or under shingles, especially noticeable after a storm. Why Sunny-Day Inspections Are Safer and Smarter Inspecting your roof while it's dry is not just more effective—it's also safer. Slippery surfaces and low visibility during storms make for dangerous inspections. When it’s sunny, you have better lighting and stable footing, making it easier to catch the small details. Call in the Experts At SunSent , our team doesn’t wait around for a leak to start causing damage. We know that post-rain, sunny days are the perfect time to get ahead of roofing issues. Whether it's a full inspection or a quick check-up, we can help you avoid costly surprises down the road.  Don’t wait for the next storm. Schedule your roof inspection today and let the sunshine help us find what the rain tried to hide.

The U.S. solar industry is no stranger to trade turbulence, but recent moves from the White House have sent shockwaves through an already complex landscape. As new tariffs hit Southeast Asian solar imports—the backbone of the U.S. solar supply chain—the big question for the industry becomes: can a surplus of stockpiled solar panels act as a buffer against economic disruption? At SunSent Solar , we’re diving into the numbers, the policy shifts, and the industry responses that could determine whether this tariff wave sinks solar progress or helps build a stronger domestic foundation. 📉 The New Tariffs Are No Joke In April 2025, the Biden-to-Trump transition brought with it a brutal new trade policy dubbed the “Liberation Day” tariffs. The new tariffs target Southeast Asian nations—countries responsible for over 80% of U.S. solar panel imports. Here’s what the new tariff landscape looks like:

​Electricity prices in Missouri are on the rise, and the trend shows no signs of slowing. For Ameren Missouri customers, the cost of power has surged by over 36% in just the past three years. This June, rates will jump another 12%, adding $355 million annually to Ameren’s revenue, as approved by the Missouri Public Service Commission . But that’s just the beginning.​ A new Missouri law allows utilities to charge customers upfront for power plants that haven’t even been built yet. T his legislation repeals a 1976 voter-approved law that protected ratepayers from paying for projects before they were operational. Consumer advocates warn that this change could lead to a 60% increase in electric bills next year, adding approximately $1,000 annually to the average household’s expenses.

Let’s cut to the chase: if you've ever considered going solar, 2025 might just be your last, best chance to do it for cheap . With a massive 30% federal tax credit still in play, and a warehouse stocked with pre-tariff solar panels ready to roll, SunSent Solar is making it easier and more affordable than ever to flip the switch on your energy independence. Sound too good to be true? Stick around. We’ll break down everything you need to know about the solar tax credit, why it matters right now, and how SunSent can help you save big — before potential changes hit your wallet hard. First Things First: What’s the Federal Solar Tax Credit? The federal solar investment tax credit (ITC) is a dollar-for-dollar reduction in the amount of income tax you owe. That means when you go solar, you can claim 30% of your total system cost as a credit on your federal tax return. 💰 Translation: If your solar setup costs $25,000, you can slice $7,500 right off your tax bill. That’s real money back in your pocket. There’s no cap on how much you can claim, and no income limits , which means everyone — not just the ultra-wealthy — can take advantage. And here's the kicker: this 30% credit is locked in only until 2032 . After that, it's on a countdown to zero by 2035. But with political shifts and proposed funding freezes circling like vultures, there’s no telling how long this golden window will really stay open. Why 2025 is The Year to Go Solar 1. The Tax Credit is Still 30% — But Maybe Not for Long Despite headlines and executive orders threatening funding for the Inflation Reduction Act (the legislation that guarantees the solar tax credit), Congress already approved 2025’s incentives , which means you’re still in the clear this year .  However, nothing in politics is ever really certain. Legal challenges are mounting. Funding pauses are being debated. You don’t want to wait until the dust settles to start saving. 2. We’ve Got Pre-Tariff Panels in Stock — That Means Cheaper Installs for You A new wave of tariffs on solar panels from Southeast Asia is about to drive prices up nationwide. Luckily, at SunSent Solar, we planned ahead . Our warehouse is stocked with top-tier, pre-tariff panels , which means we can lock in the current low costs before the price hike hits. But once they’re gone — they’re gone. 3. You Can Stack the Federal Tax Credit With Other Incentives In Missouri and Illinois, there are local rebates, sales tax exemptions, and property tax protections that add even more value when you install solar. Plus, with net metering , you can get credited for excess energy you send back to the grid. Bottom line? You’re saving money upfront, long-term, and on your taxes . It’s a triple win.

The solar industry is in a shake-up—and not everyone is going to make it through. While some of the biggest names in residential solar are collapsing under the weight of debt, overhead, and shady practices, local solar companies are doing what they’ve always done: showing up, doing honest work, and delivering real value to homeowners. So what’s happening—and why does it matter now more than ever? Big Solar's Business Model is a House of Cards Let’s cut to the chase. Companies like Sunnova, SolarCity, and ADT Solar bet big on aggressive expansion, high-risk debt, and sales-first, service-second strategies. According to a new article from EnergySage , most big solar businesses are “walking on very thin ice,” and that ice is finally cracking. From SolarCity’s 2016 fall to the recent closures of Pink Energy, Vision Solar, Titan, and SunPower, the message is clear: bigger isn't better—it's riskier. These companies often rely on complex financing structures that delay payments to installers and leave customers holding the bag. Many outsource sales to commission-only contractors with no real understanding of solar, leading to overpromises, bad installs, and frustrated homeowners. Small Solar, Stronger Results By contrast, small and regional solar companies like SunSent Solar are thriving. Why? Because we actually know your name. We're here after the install. And we’re built on doing the job right—not scaling across 30 states or satisfying shareholders. Industry expert Joe Marhamtati explains it best: “These local companies really care about their customers more than they do about shareholder returns.” At SunSent , we’re not just another sales office. We're your neighbor, your installer, your ongoing support system.

As new tariffs threaten to raise solar costs, Earth Day reminds us why clean energy is still our best shot at a brighter future.

House hunting? You’re probably juggling a hundred decisions—neighborhoods, schools, square footage, countertops. But if you find a home with solar panels already installed, you might’ve just stumbled into a pretty great deal... or a massive headache. Let’s break it down so you don’t get burned. So, the house has solar. Is that a good thing? Yes, it can be. Solar panels slash electric bills , boost property value, and let you stick it to rising utility costs. But the devil’s in the details: who owns the panels, how they were paid for, and what condition they’re in all matter a lot. 1. Find out how the panels were paid for Before you fall in love with that energy-efficient dream home, ask this: Were the panels paid for in full ? Are they leased ? Is there an outstanding loan ? Were they financed through PACE ? Each option comes with its own checklist. Here’s what you’re getting into: 2. Fully Owned Solar Panels = Best Case Scenario If the seller paid upfront for the solar system, you’re golden. No monthly payments, no contracts, just savings. You'll want: ✅ A copy of the purchase agreement ✅ Transfer paperwork from the installer ✅ Warranty info ✅ A Net Metering (NEM) agreement with the utility Just know that federal tax credits already claimed by the original owner don’t transfer to you—but other local incentives might. Ask! 3. Leased Panels = Proceed with Caution Leased solar isn’t necessarily bad, but it is more complicated. You’re taking over someone else’s contract, so: Get a copy of the lease Ask about monthly payments Look for escalators (automatic yearly increases) Check for early termination fees See if there’s a buyout option Oh—and make sure that lease won’t interfere with your mortgage approval. Lenders do care. If the system is under a PPA (Power Purchase Agreement), you're paying per kWh used instead of a flat monthly rate. Do the math and make sure it still saves you money. 4. Solar Loan? You Might Not Have to Worry In most cases, the seller will pay off the loan before closing, and the solar system gets wrapped into the home’s value. But if they want you to assume the loan, ask: Is it secured or unsecured? What’s the interest rate? What’s the remaining balance and loan term? Also check if the system qualifies for net metering or performance-based incentives that offset your payment. In some states (like Missouri), PACE financing gets paid through property taxes. That stays with the house. If you’re buying a PACE home, make sure the numbers still work for your budget. 5. Check the Roof (Seriously) Solar panels are great, but if the roof underneath is falling apart? Not so much. Get the roof inspected. 🛠️ A general home inspection isn’t always enough 🛠️ Consider a dedicated roof inspection ($150–$500) 🛠️ If repairs are needed, panel removal can cost $1,500–$6,000 Use this info to negotiate. Don’t get stuck footing the bill for someone else’s deferred maintenance. 6. Check the Panels, Too Solar panels usually last 25–30 years, but they do degrade slowly over time. Ask for: Performance reports or access to the system’s monitoring app Warranty information (most are transferable) A rundown of any past maintenance or repairs Make sure they’re still doing what they were installed to do—saving money. Bottom Line A house with solar panels can be a huge win—if you do your homework. Always ask the seller and your agent for documentation and don’t be afraid to loop in your own inspector, electrician, or solar installer to give the system a second look.
