Cash in on net-metering while you still can!

Cash in on net-metering while you still can!

The rationality of net-metering is hard to deny: If your home generates more energy than it consumes and that energy is added back into the grid, it’s only fair you should be compensated for the contribution. However utility companies, who usually end up footing the bill, are of a different opinion. As of January 2016 more than half of the 40 U.S. states with net-metering incentives have had their policies come under scrutiny. At the start of the year, homeowners in California breathed a collective sigh of relief as state regulators narrowly voted to uphold the existing net-metering benefits. However their neighboring solar enthusiasts in the state of Nevada weren’t so lucky. As more people are switching to using solar and generating their own power, state regulators have been forced to balance on a high wire of encouraging the trend while also pacifying the big energy companies that power houses during non-daylight hours. Check out the map below to see if you’re in one of the blue states where net-metering incentives are still applicable. If you are, and haven’t yet made the switch to solar, time might be running out to cash in on making more sun energy than you...

SunJack – World’s Most Portable 20W Solar Charger Live on Kickstarter

Harold Tan, one of the team members at GoGreenSolar.com, has launched a new Kickstarter campaign to build and market SunJack, the world’s most portable 20-Watt solar charger and battery pack for off-grid applications and emergency mobile power. The campaign will also benefit the rural villages of Papua New Guinea with smoke-free lighting and energy. As an off-grid camper and extreme outdoorsman, Tan knows how important charged electronics can be in isolated areas. But whether power was needed for light, weather information, or communication, Tan saw that solar powered chargers on the market today were flawed. They gave too little power too slowly. With today’s power-hungry mobile devices, off-grid campers could wait 12 hours or more to fully recharge and have enough stored energy for map apps, rescue calls, night lighting, or just enjoying music at night. Realizing the need, Tan designed the SunJack system, a 14 Watt or a 20 Watt fast-charging solar powered battery system that’s lightweight and easily folds into the size of an iPad. When completely opened, the lightweight SunJack systems can be securely attached to a backpack and fully replenish its batteries in approximately 5 hours of direct sunlight. With the 14 Watt model, SunJack’s 8000 mAh lithium-polymer battery can charge two USB devices simultaneously, run independently from the solar panels, and has a built in LED light for off-grid lighting. With the premium 20-Watt SunJack model, family campers can receive 16000 mAh capacity, enough to power up to 8 iPhones, or 1.4 iPads or 8 hours of 5 Watt lighting. SunJack is unique for its proprietary USB port and a lithium-polymer battery that was specially designed for faster charging from sunlight. “Think of it as being able to get more water out of your faucet faster,” said Tan. “The SunJack is able to get more electrons flowing into the battery faster than any solar charger available, which means you get wall-outlet charging speeds in an incredibly portable form-factor.” But SunJack is more than an off-grid power system for boats, beach days, emergencies, and rock climbing trips. It’s also a path for non-toxic lighting for the rural villages of Papua New Guinea. For certain levels of Kickstarter investors, Tan will donate a SunJack and an LED light to a rural village, enabling rural families to learn to read and perform indoor chores at night without breathing noxious kindling wood fumes. The SunJack Kickstarter campaign is running from now until Thursday, May 15th and will offer backers several early investor values, including portable solar lights and significant discounts off SunJack’s projected $250 retail price. If the Kickstarter campaign is successful, backers should receive the first production...

What’s wrong with solar permitting? Q&A with Deep Patel, CEO of GoGreenSolar.com

Experience any roadblocks while trying to pull a permit for a photovoltaic (PV) system in your city?   Paying too much?  You’re not alone.  Getting your PV system a permit can be a daunting task for both customers and installers. According to report by Clean Power Finance, about 23% of PV installations cost more than expected.   More than a third of solar installers actually avoid working with certain Authorities Having Jurisdiction (AHJs) because of their solar permitting processes. What’s wrong with these permitting processes and what can we do to fix it?  What’s being done right now? No standardized permitting process or fees have been set among AHJs, or the entities that have the power to determine and enforce code requirements for PV systems.  I’m catching up with GoGreensolar.com CEO Deep Patel to touch on some of these issues. From a solar contractor’s perspective, how do varying permitting procedures affect your business? It makes it more difficult to generate a proposal.  There really is not a cookie cutter solution, so unfortunately we can’t just generate proposal on the spot.  It often takes weeks because we have to call the Authority Having Jurisdiction (AHJ), leave messages, and wait for them to call us back. So when you’re trying to get a proposal out, it often takes up your time.  This increases the wait-time for customers and often drives up the soft costs of solar.  Would you say that this cost is passed along to consumers? Yes, proposals currently have to account for this unpredictability. When you’re running a business with that kind of uncertainty, you have to pad the proposal in case of any unexpected fees or codes changes. In an attempt to bring down the time and soft-costs that come with this inconsistent permitting process, the DOE’s Sunshot supported Clean Power Finance’s efforts to develop a National Solar Permitting Database.  The goal is to provide solar professionals a platform to give testimonials about different AHJs and coach each other through these permitting processes.  I guess you could say it’s like Yelp for solar contractors to review AHJs. A National Database can help solar contractors work more efficiently, but is it not placing a Band-Aid on a bullet wound?  Given that the DOE already has a standardized set of permitting policies known (solar ABCs), is it even fair that the burden of navigating these arduous permitting processes is imposed on those who are installing solar electric systems?  The problem is that the DOE doesn’t have the jurisdiction here.  The DOE can’t force the cities to follow a standardized permitting process, but they can make recommendations and city governments can choose to adopt them.  Meanwhile,...

3 Ways Enphase M215 Just Got Better

Enphase Energy just revealed some key improvements to the Enphase M215, 215 Watt microinverter and their system as a whole. Take a look at the new features… 1. Enphase M215 with Integrated Ground Photovoltaic (PV) systems in North America have normally required bonding each microinverter together with continuous copper grounding wire.  The purpose of this standard is to prevent fires, protect workers from shocks, and comply with National Electrical Code (NEC).  Some changes to NEC have allowed Enphase to incorporate integrated (DC isolated) ground technology into their 4th generation line, which now includes the M215. Because the DC circuit is isolated and insulated from the ground, you can now safely install Enphase M215 microinverters without a Grounding Electrode Conductor (GEC) connected to each microinverter. Coming soon… the 4th generation M215. Download the new M215 Microinverter data sheet (PDF). As you can see in the image above, the M215 now has a flat lid with no grounding lug. Yes, this product meets U.S. National Electrical Code (NEC) requirements Ungrounded Photovoltaic (PV) Power Systems and it’s actually a safer product. Integrated Ground(IG) technology simplifies this cumbersome installation process, reducing materials and labor costs.  Installers and D.I.Y. customers already prefer to use Enphase for residential systems because of its straightforward installation.  The new M215 further simplifies the process because there’s no need to run copper wire between each microinverter. Sound familiar?  Last year, Enphase released their fourth generation model, the Enphase M250, which also features this new IG technology.  The Enphase M520, however, is optimized for solar panels all the way up to 300 Watts. The Enphase M215 is compatible with modules up to 270W, a lower wattage range where consumers are finding the best dollar per Watt on solar panels.  So basically, Enphase put all the benefits of the M250 into the M215. Oh yeah, the new Enphase M215 also has a CEC efficiency rating of 96.5% compared with the previous version’s 96%. For more information on the new M215’s integrated grounding feature, please see Enphase’s M215 white paper. 2.  Wi-Fi option for the Envoy Communications Gateway Now Available! The Envoy Communications Gateway is the hub connects your Enphase microinverter system to Enlighten, Enphase’s web-based monitoring software for PV systems. Instead of running an Ethernet cable from the Envoy hardware into a broadband router, you can now connect the Envoy Communications Gateway with the new wi-fi option (pictured top right). The new Wi-fi option simplifies connectivity and makes finding a location for the Envoy way easier. Connect up to 600 microinverters to one Envoy.   3. MyEnlighten & Enlighten Manager Software Customers who use the Enphase Envoy to monitor their systems get...

Will solar work in your state? (Infographic)

Will solar work in your state? (Infographic)

Do photovoltaics(PV) really work outside of California?   When first looking into solar, it seems only natural to assume that solar panels will work best in hot areas. Contrary to this intuition, solar panels perform best in cool environments.   You’ll get the maximum yield from your PV system when direct sunlight is hitting your array, but solar panels continue to generate electricity with ambient sunlight on cloudy days. Tip: monocrystalline solar panels are known to be more efficient in low-light conditions than polycrystalline solar panels. Rain can also rinse off “soiling,” or the dirt and dust that builds up on solar panels, making them operate more efficiently. Some areas also have rewarding “net metering” policies that credit you for the the energy your PV system generates on those clear days.  It’s fed into the electricity grid and later used to offset your energy consumption (kWh) on cloudy days or at night when you’re drawing from the utility grid.   To learn more about grid-tied PV systems, read Grid-Tied and Off-Grid Solar 101. With the installed price of solar photovoltaic (PV) systems declining, investing in clean energy is more cost-effective than ever.  Solar is even saving homeowners money in cloudier cities like Seattle and Portland. Solar is steadily appearing on more rooftops throughout the country- which U.S. cities have you noticed more PV systems being installed?...
