For those looking for the most efficient solar panels for their PV system, the first thing you need to know is how to compare efficiency metrics for different manufacturer brands. Simply put, efficiency (expressed as a percentage) quantifies a solar panel’s ability to convert sunlight into electricity. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings, the more efficient panel will produce more electricity than the less efficient panel.
In practical terms, for two solar panels of the same physical size, if one has a 21% efficiency rating and the other has a 14% efficiency rating, the 21% efficient panel will produce 50% more kilowatt hours (kWh) of electricity under the same conditions as the 14% efficient panel. Thus, maximizing energy use and bill savings is heavily reliant on top tier solar panel energy efficiency.
What does it mean to have a solar home, or to “go solar”? Photovoltaic technology is rapidly spreading and becoming more accessible, and more and more homeowners are going solar daily. In this article, we will explore what it means to have a solar home in 2017.
Some of the lowest prices for solar equipment can be found on sites like eBay, where people can post their used solar panels for sale a discounted price. In this article, we will look into the used solar panel market, and whether buying panels from a reseller is the best option for your home solar setup.
While it has been evident that solar power has been taking off across the U.S. in the past decade, it’s been less clear where the majority of the growth is occurring. Though certain states (California, Arizona) are known to be major states for rooftop solar, others like Oregon have stayed somewhat under the radar. With one of the best state solar tax credits available only through the rest of this calendar year, now is a great time to go solar in the Beaver State and cash in on impressive savings under the expiring tax credit.
This week, EnergySage released its fifth Solar Marketplace Intel Report™. In this report, you’ll find trends on solar pricing over the past 12 months, as well as equipment and financing options for solar. In addition, this report includes new information about community solar and the level of solar interest in states across the country. Read on for some of the top takeaways relevant to today’s solar shoppers.
Who are the top solar companies in the world and in the USA? Industry analysts from SPV, SEIA and other organizations offer their top rankings, based on updated shipping forecasts from each of the companies included. Continue reading →
Reducing your carbon footprint and simultaneously saving money is easier than ever with the growth of energy-saving technologies. From LED light bulbs to devices that monitor your appliances to solar panel systems, there are many opportunities to put smart technologies to work saving you energy around your home and lowering your environmental impact each day.
Home energy storage has featured frequently in the news over the past few months thanks to new battery products from companies like Tesla, LG and Mercedes-Benz. These products are popular for a reason: when you pair solar panels with a battery bank at your home or business, you can actually operate independently from the electric grid. However, not all solar batteries are created equal. Here’s the rundown on what it actually takes to use a solar panel battery bank to go off the grid.
Solar plus storage is a rapidly advancing technology that makes it possible to both generate and store solar energy onsite for backup power. Solar batteries can also help homeowners and businesses maximize solar energy use onsite. The cost of installing a battery is high today, but prices are falling rapidly. As a result, many property owners are installing a solar panel system now and planning to add energy storage later on.
How can you ensure that you’re set up for success when you decide to move forward with a solar battery for your home or business? Designing a “storage-ready” solar panel system is the first step. EnergySage interviewed four solar inverter manufacturers to offer more insight into the concept of “storage-ready” solar. The highlights and key takeaways from each manufacturer are below, and links to each company’s full range of responses on storage-ready solar are at the bottom of this article.
