What is an off grid solar system? What does it mean to go “off the grid” with solar?

Reading Time: 8 minutes

People say all the time that they want to get off the grid. Beyond just meaning getting away from it all for a while, getting off the grid has a specific technical meaning with regards to your relationship to your utility and how you get your power. So, what exactly does it mean to go off the grid? If you’re going off-grid, there are tons of options to consider when it comes to batteries, inverters, panels, mounting systems, and solar charge controllers. Each product is different and you can customize your kit in a countless number of ways, which is why it is vital to know exactly what you’re looking for and why. Generally, an off grid solar system has the following parts:

  1. Solar panels 
  2. Solar inverters
  3. Wiring/cables
  4. Mounting equipment 
  5. Charge controller
  6. Batteries 
  7. Safety equipment (safety disconnects, grounding equipment, surge protection)

The Tesla Powerwall home battery complete review

Reading Time: 7 minutes

Back in 2015, automaker Tesla Motors set its sights on the home energy storage market and announced the launch of its home battery product, the Tesla Powerwall.

In the past, Tesla Motors has been praised for making high-quality electric vehicles, as well as for their ability to reimagine and successfully rebrand existing technologies. In fact, while Tesla’s automobiles revitalized the 21st-century electric vehicle market, the first electric cars were invented more than a hundred years earlier. 

Tesla’s rebranding of residential-use batteries is in line with their legacy of reimagining existing products. Tesla’s battery may represent the first time in history that everyday homeowners are truly excited about the potential of storing energy at their home. The Powerwall, combined with the exciting Tesla Solar Roof, are both potential cornerstones of Elon Musk’s sustainable energy vision for the future.

How does a photovoltaic solar cell work?

Reading Time: 7 minutes

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 photovoltaic solar cells, or solar cells, which are electronic components that generate electricity when exposed to photons, or particles of light—this conversion is called the photovoltaic effect. In this article, we’ll explain how PV cells work. Specifically, we’ll examine the science of silicon solar cells, the solar cells making up the vast majority of solar panels.

The federal solar tax credit: all you need to know

Reading Time: 5 minutes

The investment tax credit (ITC), also known as the federal solar tax credit, allows you to deduct 26 percent of the cost of installing a solar energy system from your federal taxes. The ITC applies to both residential and commercial systems, and there is no cap on its value. The average EnergySage Marketplace shopper saves nearly $9,000 on the cost of going solar as a result of the ITC. Curious as to how much you can save on solar? Read our article for more information based on your unique energy needs.
