If you’ve ever seen a solar panel (and hopefully you have!), chances are it was a crystalline silicon solar panel – the dominant type of solar cell out there. If you’ve done a bit more research on panels, you might be aware that there are actually two types of crystalline silicon panels: polycrystalline and monocrystalline.
You might’ve heard that one produces more energy or is more efficient or another is more cost-effective. What’s the real difference between monocrystalline solar panels vs polycrystalline solar panels? And does it even matter?
The difference between the two lies in the manufacture and makeup of their underlying material: silicon. Let’s take a look to see what all this means and ultimately help you decide which type to install.Continue reading
It's our job to research the major players in the solar industry to save you some of the hours of legwork involved in researching and purchasing your new system. We will take a look at Vivint solar reviews from a variety of sources below, highlight the compliments and complaints, analyze the review trends, and see how they stack up against similar companies in their niche. Numbers are current as of the writing of this post.
You want your solar panels to deliver the maximum amount of energy possible, right? But did you know how your solar panels are connected within the electrical wiring of your house makes a difference in how well they work? Connecting your solar panel in series vs parallel affects current flow and is dictated by your installation’s setup.
Warning: Science below! While we’re not going to get too deep into the details, the difference between connecting solar panels in series vs in parallel is an intermediate level solar discussion. If you’re looking for something a bit more on the beginner level, check out our articles How Do Solar Panels Work? and Everything You Need to Know About Solar Inverter Types.
OK, now that the disclaimer is out of the way, we’re ready!
Maybe you opened up a solar panel’s spec sheet and quickly spiraled into confusion because of words like wattage, efficiency, power tolerance, and temperature coefficient. What do all these mean? And which one of these solar panel ratings are most important when evaluating a solar panel?
We are here to help! Today, we’re going over all the different categories of solar panel ratings, describing what they are, what they measure, and which ones are important. After reading this article, you’ll have everything you need to both understand and evaluate solar panels.Continue reading
Solar panels come in many varieties, and there are different types of panels for every occasion. Since going solar is a major investment in your home, it’s good to be in-the-know before you invest. And that’s where we come in.
Reaching a high power conversion efficiency has always been the goal of solar energy.
Last year, the development of perovskite-silicon solar cells by the Hong Kong Polytechnic University showed great promise by reaching the world’s highest power conversion efficiency of 25.5 percent. This was accomplished by designing a transparent perovskite layer with an optimized thickness that allowed the absorption of light into the silicon part of the solar cell.
Then a few months later, a team from Eindhoven University of Technology showed that adding a few nanometers of a thin layer of aluminum oxide would protect a perovskite solar cell against humidity while increasing power efficiency by three percent.Continue reading
That’s what makes it renewable energy, right? But that’s a fairly simplistic answer.
Sunlight has numerous characteristics. Humans have used the heat of the sun for centuries to warm buildings to make them nice and cozy inside. Today, we use the sun’s heat for thermal solar panels used to preheat water coming into residential hot water tanks, as well as for huge utility-scale concentrated solar power.
But for solar electricity, it’s not the sun’s heat. It’s all about photons. This goes back to the century-old science-classroom debate over whether light is a particle or a wave – an intense debate because light can diffuse and refract like a particle, but has no mass like a wave. Einstein eventually helped us out by deciding that light is a photon, a word we made up to describe this thing that has characteristics of both waves and particles.Continue reading
This magic happens within a sheet of material that looks to the naked eye just as inert as any other material object.
Silver has long been viewed as an investment in its own right as an inflation hedge.It is also widely used in the manufacture of semiconductors, batteries, various nanotechnology applications, jewelery, photography, and in making solar photovoltaic cells.
What nonsense. This is, as my Great Aunt Ro would put it, “simply arrant drivel.”
Let’s go through the process. Look around you. Everything you see is manufactured somewhere. All manufacturing takes energy.
The massive turbines that use the steam by boiling water by burning coal, and turn that into electricity take energy to make. Like all manufactured objects, solar panels are manufactured. Do they take more energy?
