Fully Charged's Robert Llewellyn upgraded his home solar array this Summer from 2.2 kW to 5.5 kW, and also added an energy storage system - specifically, the Tesla Powerwall 2.
And as such, a new episode presents the installation from a customer perspective in the UK, including an overview of the whole set-up, a Tesla application demo, and a talk about energy storage.
The Tesla Powerwall 2 is rated at 13.5 kWh,with 5 kW of continuous power output, which is one of the most energy dense and price-competitive ESS systems on the market.
The Tesla ESS (well, really any energy storage solution) offers a better utilization of site-generated renewable energy, and is another step that lets one be more independent from the grid.
However, according to Robert, having energy storage (as of today) as part of the equation, will extend the payback period over just a solar installation. Hopefully in the future it will be more affordable, and bring also some savings; a trend which we have seen over the past few year.
