Launch of multiple styled solar roof tiles

EE Publishers

Electric vehicles maker Tesla Motors recently presented a much-awaited solar roof product developed with SolarCity. The tiles are made from quartz glass and solar cells. The solution will cost less than a traditional roof when the expected utility bill savings are taken into account, the company says. The solar tiles are one element of a three-part solution, including also energy storage and electric cars. Midsummer’s Sven Lindström’s wrote an analysis “Solar on houses needed for 2020 target” recently where he says the future of urban solar energy lies in integrating PV into roofing materials and facades already at the factory. Lindström says that because Tesla has shown its ability to produce electric cars successfully, he is confident that PV roof tiles will be so successful that roof material manufacturers that do not have a PV solution maybe need to re-think their business model.

Elon Musk hits the road with his master plan – Go, Elon, Go!

BDLive, 21 July, 2016.

DETROIT — On Wednesday, Tesla Motors CEO Elon Musk unveiled an ambitious plan to expand the company into electric trucks and buses, car sharing and solar energy systems.

In a blog post titled “Master Plan, Part Deux”, Musk sketched a vision of an integrated carbon-free energy enterprise offering a wider range of vehicles, and products and services beyond electric cars and batteries.

The newest elements of the strategy included plans to develop car-and ride-sharing programmes, as well as commercial vehicles — businesses where other companies already compete, and in some cases have ample head starts on Tesla…

Wind and solar become new “base load” power for South Australia

Australia Energy Week, 16 May, 2016.

This article outlines precisely how/why we don’t need baseload power and increasing amounts of variable renewable energy can be integrated into the grid without creating reliability issues or increasing costs.

Wind and solar become new “base load” power for South Australia

By Giles Parkinson

It has only been a week since the closure of South Australia’s last coal-fired generator, but already a new pattern is emerging that points the way to a new energy system, away from “baseload” built around coal, gas or nuclear, to a new system built around wind and solar and other renewables.

This graph – provided by Dylan McConnell from the Melbourne Energy Institute, shows he first week of production since the closure of the Northern brown coal generator on May 10.

It shows wind energy provided the vast majority of power over the past seven days, supplemented by some rooftop solar, and by peaking and combined cycle gas plants.

This is expected to be the pattern of the future, as energy systems with high renewable energy penetration rely first on variable energy providers such as wind and solar, and then on “flexible” or “dispatchable” energy from the likes of gas, but ultimately hydro, solar towers with storage, and emerging technologies such as geothermal and ocean energy and battery and other energy storage.

New residential energy solution launched in South Africa

Engineering News, 19 April, 2016.

A residential energy solution, which allows homeowners to generate and store their own electricity, has been officially launched in the Western Cape market by Energy Partners Home Solutions, a division of PSG. Dubbed the ‘Icon Home Energy Hub’, the solution comprises roof-mounted solar panels with a 3.1 kWp capacity and an inverter, which converts direct-current electricity produced by the panels to alternating current. The inverter is integrated with a 3.6 kWh lithium-iron phosphate battery, which is able to store energy for use during higher-tariff peak periods. Print Send to Friend 5 0 In fact, the full household solution also includes a hot-water tank, a heat pump and a remote monitoring platform allowing the user to monitor the status of their system directly through a mobile app. However, the company has opted for a modular deployment approach and is willing, for instance, to install only aspects of the overall offering, depending on a homeowner’s requirements. The full solution will cost R167 000 before value added tax and is designed primarily for medium-sized households with a monthly electricity bill of above R1 500.
