The electrical grid is designed with redundancy in mind. In order to avoid any consumers losing power, and especially any prolonged drops in power, utilities and the grid operators have designed backup plans and backups to those backups. Although very rarely, if ever, necessary, the last of those backup plans is perhaps the most important of all: black start resources.
As more and more customers express interest in solar plus storage on EnergySage’s Marketplace, many do so with the same intended purpose: resiliency. When the grid goes dark, these solar shoppers want to ensure that they are on an electric “island” to keep their own lights on, self-generating and storing solar electricity that they can then consume. The solution? Microgrids.
Partially in response to major storm events nationwide, this innovative, if not new, approach is being taken throughout the country to maintain greater reliability and to return power quicker at the local level. By taking the notion of an electrical island from a single home to multiple buildings or an entire community, communities, cities, and organizations are creating microgrids.
If you’re considering a home energy storage option, there are several types of batteries to choose from. In this article, we’ll compare two of the most common battery options paired with solar installations: lithium-ion and lead acid.
Update: in October 2018, Tesla raised the price of the Powerwall 2 to $6,700. Supporting hardware costs an additional $1,100. These prices do not include the cost of installation.
Tesla brought solar batteries to the forefront of home energy technology with the launch of the Powerwall in 2015. A year later, Elon Musk announced the new and improved Tesla Powerwall 2, an industry-leading product that takes solar-plus-storage to the next level. The Powerwall 2 offers a few much-needed improvements over the original Powerwall product, including a larger storage capacity, a lower per-kilowatt hour cost, and a built-in inverter.
Solar offers more than just an opportunity to reduce your carbon footprint. When you install solar panels on your roof, you are a step closer to taking your electricity production and consumption into your own hands. One of the biggest decisions solar shoppers have to make is whether to install a standard grid-tied solar energy system, a solar battery backup, or a hybrid solar system. Here’s everything that you should keep in mind when you’re comparing hybrid solar panels to typical grid-connection or off-grid options
PG&E’s new rate schedule affects utility’s entire coverage area in 2019. Whether you have solar panels on your roof, are considering solar, or don’t have any plans to generate your own electricity, the time-of-use (TOU) rates will have an impact on your monthly electricity costs. Currently, all PG&E customers have the option of switching to TOU rates or remaining on their existing rate schedule. However, if you are a new PG&E customer or move to a new address, you’ll have to choose a new TOU plan. The best option for your home depends on your electricity use habits.
Home energy storage is a relatively new technology that’s steadily gained interest over the past few years, and it’s hard to know where to start when comparing all your options. Top solar batteries like those made by Tesla and Sonnen make it possible for homeowners and businesses to store their excess solar energy instead of sending it back to the grid, so that when the power goes out or electricity rates spike they can keep the lights on.
Following the news of Tesla’s acquisition of U.S. solar installer giant SolarCity, the world has been keeping a close eye on Elon Musk and his two prosperous clean energy ventures. Tesla and SolarCity, electric cars and solar panels – a two-front war waged against grid reliance and energy dependence. In 2019, Musktopia is both expanding and constricting as two of the tech entrepreneur’s five companies are joining forces around one common goal: decimating your carbon footprint.
LG Chem launched their first home battery in North America – the RESU10H – in mid-2017. In a crowded energy storage system market, LG provides an already-recognizable brand with household consumer products. EnergySage conducted a Q&A with LG Chem to better understand how debuting RESU10H aligns within their current lineup of appliances, and to learn what customers can look forward to in 2019.

Early in 2018, Fortress Power released two energy storage systems in the United States – a 10 kilowatt-hour (kWh) and a 15 kWh model. Their foray into an increasingly packed residential storage system market is with a different type of chemistry – lithium ferrite phosphate – than many other options available on the market. EnergySage sat down for a Q&A with Fortress Power to learn more about the company, why customers should consider energy storage, and how Fortress Power batteries differ from other brands in the market.
