Black start: why it matters

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.

What is black start?

What are microgrids and how do they work?

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.

Which PG&E rate schedule is best for solar? Understanding peak hours

PG&E’s new rate schedule affects utility’s entire coverage area in 2020. 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.

How do solar batteries compare? Tesla Powerwall vs. Sonnen eco vs. LG Chem RESU vs. Pika Energy Smart Harbor

NOTE: We’ve written an updated review of some of the current popular home battery products. Check it out here.

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.

Q&A with Fortress Power

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.

How do solar panels work at night and on cloudy days?

If you’ve been wondering “do solar panels work at night or on cloudy days?, you’re certainly not alone. While they don’t work at night, you will still be able to use excess electricity depending on your system. On cloudy days, they will still be able to work, generating 10-25% of their normal power output.If you choose to rely on solar panels for your home electricity use, it’s important to understand how solar panels can be a reliable source of power during night time when there is no available sunlight.
