Solar generators

Our guide to the best solar generators

Solar isn’t just for rooftops – you can use portable solar products like solar generators as a backup power source if the grid goes down, or as a source of electricity for your campsite, RV, or boat. But what is a solar generator exactly? And how does it compare with typical fossil-fuel powered generators? In this article, we’ll break down the key things you need to know about solar generators so you can decide if they’re right for you!

Solar panel recycling: what you need to know

Solar power is one of the fastest-growing clean energy sources, but what happens to old panels? Solar panels have a lifetime of about 30 years. With the increasing number of solar panels being sold and installed in the U.S. each year, it’s only a matter of time before high volumes of panels are at the end of their useful life and have to be disposed of. Solar panel recycling is still at an early stage, but as the renewable energy market continues to expand, recycling processes will play an increasingly important role.

Sun Score: what you need to know about your property’s Sun Number

If you’ve shopped for solar before, you may have come across something known as “Sun Number” or sun score. Like EnergySage, Sun Number received funding from the Department of Energy’s SunShot initiative to innovate in the solar energy space. Read on to learn more about how a property’s Sun Number is calculated and what your sun score means for going solar.

how many watts refrigerator

How many watts does a refrigerator use?

On average, a refrigerator uses 300 to 800 watts of electricity, depending on how old the model is. Most refrigerators use between 3 and 6 amps and about 120 volts. Your refrigerator is one of the larger electrical appliances in your home, and it’s always on! If you’re looking to cut down on your electrical bill or estimate how many solar panels you need to keep your home up and running, understanding how many watts of electricity a refrigerator uses is one important piece of the puzzle.

solar tax credit

Everything you need to know about the federal solar tax credit

The investment tax credit (ITC), also known as the federal solar tax credit, allows you to deduct 30 percent of the cost of installing a solar energy system from your federal taxes. The 30 percent tax credit will be available until 2033, at which point it will drop to 26 percent. The ITC applies to both residential and commercial systems, and there is no cap on its value. The average EnergySage Marketplace shopper saves nearly $6,150 on the cost of going solar as a result of the ITC.

How do photovoltaic cells work?

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 devices 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.
