Black start: why it matters

Reading Time: 3 minutes

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 are microgrids and how do they work?

Reading Time: 4 minutes

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.

Tesla Powerwall 2: an upgraded battery for your home

Reading Time: 4 minutes

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.

Depth of discharge (DoD): What does it mean for your battery, and why is it important?

Reading Time: 3 minutes

Batteries are becoming a popular add-on to solar systems thanks to the extra benefits they can offer for solar system buyers. Batteries offer backup power benefits when the grid goes down, increases the usefulness of off-grid systems, and improves solar economics if you have less than ideal net metering policies or time-of-use (TOU) rates.

Grid tied vs. solar battery backup on EnergySage

Hybrid solar systems: which pairing of on and off-grid is right for you?

Reading Time: 6 minutes

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 rate schedule increase and solar

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

Reading Time: 5 minutes

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.
