The Tesla Powerwall: We couldn’t wait, so we designed our own.
By Jack Ward, CEO of Soltra Energy
From what we’ve seen in the media, the Tesla
Powerwall lithium-ion battery pack is an attractive, wall-mounted, space-saving
unit that represents a leap forward in battery storage technology.
For users opting for solar energy
installations, either to complement or backup Eskom power – or move off the
grid completely - the Powerwall concept will certainly boost the acceptance of
rooftop solar PV-plus-battery solutions beyond all projections. It’s a
technology whose time has finally arrived.
While the Tesla Powerwall has been
eagerly anticipated by South Africans facing disruptive power outages and the
real possibility of load-shedding in the near future, the first Tesla units for
general distribution in SA are reportedly some months away.
Fortunately for local electricity
consumers, there is no need to wait. The alternative to the Tesla Powerwall is
already on the market. Thanks to local design innovation and manufacturing
excellence, the Soltra Energy Wall is available for immediate delivery. There
is no waiting for a supply channel to be formed, personnel to be hired or stock
to arrive.
One of the most attractive features of the
Soltra Energy Wall – which assuredly mirrors its opposition in terms of
specification and presentation – is the price. As can be expected, SA’s falling
rand against the US dollar has caused the retail prices of US-made goods to
soar. According to reports, final pricing for the Tesla Powerwall will likely
only become available closer to the battery’s local launch date.
On the other hand, the SA-designed and
manufactured Soltra Energy Wall – now available for country-wide installation -
is cost effective and its price is easily justifiable for a wide range of
applications. These range from domestic installations to the largest industrial
sites where synchronised, multiple wall-mounted units and a unique, utility-scale,
floor-standing version of the Soltra Energy Wall are ready for duty.
Most importantly, the Soltra Energy Wall
is backed by a world-standard 10-year guarantee (subject to a 70% depth of
discharge benchmark) and nationwide technical service by an existing, highly-trained
and experienced customer support team.
While the Tesla Powerwall has been
hailed as a game-changer, we can confirm that the locally-designed Soltra
Energy Wall has already irreversibly altered the rules by which the power
provisioning game is played in South Africa.
