How solar battery storage will affect microgrids and off-grid living

In March, Tesla cut the ribbon on this groundbreaking grid-scale battery installation, a key test of the viability of energy storage in making renewable energy a more reliable part of the grid. With 50,000 solar panels and 272 batteries, the combined solar-and-storage plant provides enough energy to power 4,500 homes for four hours. If Tesla can help keep Kauai solar-powered around the clock with its batteries, then it can apply what it has learned elsewhere in the country, and around the world

In her Longreads/Grist piece, author Amelia Urry explains the changing nature of solar power challenges that off-grid dwellers as well as smaller, geographically isolated microgrids face now that battery storage on an industrial scale is becoming more lucrative.

The article tells the story of a young couple struggling to live off the grid on the Hawaiian island of Kauai, when at the same time, the local utility cooperative switches on its brand-new bank of Tesla batteries to store the abundant solar power it generates during daytime but couldn't offer during peak times in the early morning and late evening hours: "It’s not about getting off the grid. It’s about building a better one."

IKEA starts selling home battery storage with its solar panels

Ikea is now offering solar panels and home batteries to its customers in the UK. The Scandinavian furniture chain is partnering with solar firm Solarcentury for the venture, with prices for solar battery storage starting at £3,000 (about $3,970 USD). The home batteries are designed to work with existing solar panels, or as part of a new combined home solar panel / battery storage system that Ikea is selling.

The Swedish furniture retail giant first starting solar panels in the UK back in 2013 to grow on a (then) heavily subsidized green energy market but ceased sales in 2015 when the British government announced its plans of cutting solar subsidies by up to 90%. Just a few months later, IKEA returned with a new lineup of home solar panels, this time partnering up with the firm SolarCentury.

"An average solar home in the UK will typically consume around 40% of all the solar electricity generated, or even less if they are regularly out during the day," IKEA explains in a new statement. "The remaining 60% of unused solar electricity is sent back to the National Grid, at a loss compared to its value. This means that homeowners currently lose out on making further cost savings. By adding Solar Battery Storage, unused solar electricity can be stored and used at a later time, meaning the amount of solar electricity an average home can use doubles to 80%."
