Once solar panels are set up on a property, they’ve relatively maintenance free. This is because the majority of solar panel systems have no moving parts; as long as they’re receiving sunlight and the products aren’t faulty, they will be a reliable source of electricity for 25 to 30 years.
Over the past few years, solar panels have gone from a rare sighting to a common occurrence on rooftops across America. Thanks to the financial and environmental benefits of installing solar panels, this renewable energy technology shows no signs of slowing down. Here are five facts you may not know about going solar.
Solar energy is gaining momentum around the world as more and more countries have begun transitioning to solar as a primal energy source. As the cost of solar energy has plummeted in recent years alongside major improvements in technical efficiencies and manufacturing quality, many homeowners across the U.S. are starting to look at solar as a viable alternative energy solution. And as solar enters mainstream energy markets, the big question is, “how do solar panels work?” In this article we’ll break down exactly how solar panels produce energy for your home and how pragmatic going solar really is in 2018.
The most important part of a solar panel system is the solar array itself. It holds all of the panels in your system, which is where sunlight is collected and converted into electricity. Here are some common questions to ask yourself before installing a solar panel system on your home, and to make sure you get the most productive array possible.
The U.S. solar industry has witnessed remarkable growth in the past decade while the cost of solar has declined by nearly 70 percent. Now that solar has entered the mainstream, everyday homeowners are starting to wonder how much solar could save them and how simple making the switch really could be. If you’re starting to think about installing solar panels, it’s helpful to understand the big picture for solar power. In this article, we’ll break down eight facts about solar energy that may surprise you.
You’ve probably seen solar panels on rooftops all around your neighborhood, but do you know how they actually work to generate electricity? In this article, we’ll take a look at solar photovoltaic cells – the technology behind a solar panel that creates energy from the sun.
Power output or wattage is an important factor to consider when comparing solar panel options. You may hear your solar installer say, “it’s a 255 Watt panel” or “the panel I am recommending is has a wattage of 300.” Or, when you are reading a quote from a solar installer, you might see numbers like 245W, 300W, or 345W next to the name of the panel. They are all referring to a solar panel’s wattage, capacity and power output.
How much energy can a solar panel produce?
Available sunlight will vary depending on where you live but for the sake of an example, if you are getting 5 hours of direct sunlight in a sunny state like California you can calculate it this way: 5 hours x 290 watts (a wattage of a premium solar panel) = 1,450 watts or roughly 1.5 kilowatt-hours (kwh). Thus each solar panel in your system would produce a little over 500-550 kWh of energy per year.
All solar panels are rated by the amount of DC (direct current) power they produce under standard test conditions. Solar panel power output is expressed in units of watts (W), and represents the panel’s theoretical power production under ideal sunlight and temperature conditions. Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts, with higher power ratings generally considered preferable to lower power ratings. Pricing in solar is typically measured in dollars per watt ($/W), and the total wattage of your solar panels plays a significant part in the overall cost of your solar system.
For the vast majority of the world, fossil fuels continue to be the primary source of energy production. More and more, however, renewable technologies like solar energy are rivaling the potential of traditional fossil fuels. In this article, we’ll discuss some of the disadvantages of fossil fuels, and why the future of energy likely won’t rely on these energy sources.
The past decade has engendered the era of solar panels for home use. Homes and businesses across the country are transitioning away from a fossil-fueled electricity grid towards a clean energy economy, necessitated by emissions reduction targets in a time of global climate change. Amidst this period of energy reform, solar panel systems for houses are taking off at a remarkable rate. It’s time to give residential solar the credit it deserves. Learn everything there is to know about the booming residential solar industry in our list of home solar FAQs. Continue reading
