What Is NEM?

NEM Explained

Making sense of NEM is about as simple as understanding that saving money is good. NEM, or Net Energy Metering, is both an incentive and a process that keeps utility costs down by transferring excess solar power that isn’t used to the main electrical grid. This is an exchange for credits that can then be saved until a later time; this is usually when the household’s energy consumption exceeds the solar energy that the household has produced. At this point, the homeowner can pull energy from the electrical grid, just as was done before transitioning to solar power, but it’ll be at a reduced cost because of the credits that were amassed. The credits are based on the number of kilowatt hours that were given back to the grid. These credits are then used to pull the same amount of energy at a later time. The system owner will only be billed a “net” amount of the energy used. Essentially, homes can be powered, day or night, by the solar energy that is converted and produced during daylight. 

Why choose NEM?

The metering system is a mechanism meant to balance a surplus of energy at certain times with the shortage, and need, for it at others. Solar panels convert the most energy during the afternoon when consumption is usually low, yet the inverse is that virtually nothing is converted at night, when consumption is usually higher. The method of metering uses estimates of the household’s consumption levels to then oscillate between the homeowner’s solar energy and the stored energy of the grid. This back and forth is the process of metering, which is how you save on rising utility costs.

Is NEM available?

Many states have made NEM mandatory. Only three states do not have any form of metering, nor a form of alternative compensation for excess energy. These three states are: Alabama, South Dakota, and Tennessee. Every other state either: makes metering mandatory, offers alternatives, or allows utilities that will offer metering. If you would like to learn more about the policies in our great state of Florida, use the, “Database of State Incentives for Renewables and Efficiency.” (DSIRE®) This site monitors and records metering policies for states, utilities. 

Maintaining a self sufficient, low cost household is becoming easier and more affordable than ever with solar. It’s not only beneficial to the environment but it will save you tens of thousands of dollars over the course of a lifetime.

Perovskite Could Soon Combine With, Or Replace Silicon Cells

Perovskite Solar Could Soon Combine With, Or Replace Silicon Cells

In late March, a $128 million initiative was launched to improve the costs of solar power. “A significant chunk of the money went to research into materials named after an obscure 19th-century Russian geologist and nobleman: Lev Perovski,” wrote Tom Metcalfe of NBC News. Scientists are on the cusp of discovering a better, more efficient photovoltaic solar cell. It is almost daily that new innovations and technologies are introduced within the solar energy market. Scientists are working on a new solar cell made from a type of crystallized mineral: Perovskite Perovskite could revolutionize solar cells by making it more efficient.

How Babcock Ranch Proved Solar Can Develop Cities

How Babcock Ranch Proved Solar Can Develop Cities

In 2016, the first solar panels were installed in Babcock Ranch, Florida, the Hometown of Tomorrow. Babcock Ranch considers itself to be the country’s first solar-powered town. They have become a beacon for solar energy, with over 700,00 panels installed over 800 acres. This week we will take a closer look at what Backcock Ranch means for solar energy and how it can develop in America.

Why Small Scale Rooftop, Residential Solar Is Better Than Massive Solar Farms

Why Small Scale Rooftop Residential Solar Is Better Than Massive Solar Farms

The unprecedented growth in the solar market is a marvel. It is the result of an industry that found a way to deliver a sustainable and cost-friendly alternative to fossil fuels. The Covid-19 pandemic furloughed many Americans and forced many others to work from home. Yet, solar companies were able to adapt. Internet sales replaced door-to-door sales, and the entire solar market outperformed expectations. Solar capacity has increased drastically, and there seems to be no sign of the industry slowing down.

Biden’s Infrastructure Plan: What It Means For Federal ITC & Solar

Biden’s Infrastructure Plan: What It Means For Federal ITC and Solar

President Biden unveiled his infrastructure plan this week. It’s a massive $2 trillion investment over eight years. The proposal is aptly named the “American Jobs Plan.” It looks to spur job growth while addressing the aging infrastructure. We have previously covered what a Biden presidency could potentially mean for solar energy and other renewables. The infrastructure bill includes $174 billion designated to address climate change directly. The bill intends to boost the electric vehicle market while another $100 billion is committed to upgrading the nation’s electrical grid. These efforts put the country on track for Biden’s goal of zero-emission by 2050.
