Solar and clean energy jobs easily outpace oil sector

Just in case anyone thought Tesla Motors chief Elon Musk couldn’t get more ink in these pages, he appears to be at the center of a trend that can complement his electric-vehicle development. Musk’s SolarCity solar-panel distributor competes in a green-energy sector that’s now said to be growing far faster than old-line natural-resource sectors like oil and coal. #solarenergy

Solar Power for Homes – What You Need to Know

Some suprising new developments in solar power for homes may make using solar energy in your daily life more possible than you may think!

When choosing solar power for homes, many homeowners have little idea that the systems can be tailored to the specific needs of the home. The most common type of solar energy is produced in solar panels attached to the roof of a house. These panels collect solar energy and convert that energy into useable, electrical power.

In many cases, an inverter will need to be used to convert the power from a one way feed or direct current (DC) to the alternating current (AC) that is used in most homes. The number of solar panels and the amount of wattage produced will determine the size of inverter needed and the number of inverters to be placed on the home. If the power will be stored in batteries for later use, there is no need to include an inverter on the solar panel system.

Moving Away From the Solar Panel

The solar panel is not the only type of solar power generator that can be used in the home. Technological advances have brought solar energy a long way. Today, solar backpacks, appliances, cell phone chargers, hot water heaters and heating and cooling systems have integrated solar panels that work for a specified purpose.

The solar backpack, for instance, can be used to charge a laptop or other mobile device while a student is studying outside or walking from class to class. If the student can find a window seat in class, theoretically the backpack could eliminate the need for electrical charging.

Appliances and cell phone chargers work in much the same way. The solar power that these units use is directed at powering or charging the attached unit and not production of energy for the entire home.

One of the most functional uses for solar energy can be affordably installed in the attic or roof crawl space of a home. Solar fans, powered by the sun, can be used to cool these spaces and reduce the loss of heated and cooled air from the roof of the home.

The units are installed in the roof like skylights and collect energy from the sun to power the fan. An even smaller alternative are walkway and driveway lights. These small solar energy units, collect sun power throughout the day and that energy is used to light the bulbs at night.

Will Solar Power for Homes Work for Everyone?

While solar power for homes may be ideal in many locations, using full scale home solar power systems may not be not practical for every home. The average number of sunny days per year will greatly influence the potential energy output of any solar unit.

In locations where frequent rain and snow are common, the units will not have the direct contact with the sun’s rays needed to collect solar energy and convert that energy into solar power. In these cases, the cost of installing solar panels will not be returned via savings in the home for many years.

On the flip side, places like Las Vegas, Nevada in the United States and some parts of Florida where sunny days far outweigh cloudy days, solar energy can be easily collected in amounts large enough to take a home completely off the electrical grid. Extra power can then be sold back to the electric company for credits or cash.

Tesla And Panasonic Solar ‘Gigafactory 2’

Tesla releases more details about its Solar Roof agreement with Panasonic at ‘Gigafactory 2’

In order to bring to market its new series of ‘Solar Roof’ products, Tesla announced last year that they are bringing together a lot of technologies under one roof at their newly acquired factory in Buffalo, now known as ‘Gigafactory 2‘. It includes tech developed in-house by Tesla, some tech by Panasonic, and tech from SolarCity and its subsidiaries.

The deal is somewhat complicated with a lot of moving parts, which now clearly shows why Elon Musk wanted Tesla to acquire SolarCity since it will simplify the complicated partnership.

 

Through Tesla’s acquisition of SolarCity, they inherited an agreement with the Research Foundation for the State University of New York for the construction of an approximately 1 million square foot manufacturing facility, which is now mostly completed.

The deal is under a Build-to-Suit Lease model. Tesla explains the deal in a SEC filing released this week:

“The Foundation will cover (i) construction costs related to the manufacturing facility in an amount up to $350.0 million, (ii) the acquisition and commissioning of the manufacturing equipment in an amount up to $348.1 million and (iii) $51.9 million for additional specified scope costs, in cases (i) and (ii) only, subject to the maximum funding allocation from the State of New York, and we will be responsible for any construction and equipment costs in excess of such amounts. We will own the manufacturing facility and manufacturing equipment purchased by the Foundation. Following completion of the manufacturing facility, we will lease the manufacturing facility and the manufacturing equipment owned by the Foundation from the Foundation for an initial period of 10 years, with an option to renew, for $2 per year plus utilities.”

That’s a pretty sweet deal, but in return, Tesla has to achieve a series of milestone or otherwise it will have to pay penalities.

Here are the main milestones listed in the filing:

  • employing a certain number of employees at the facility, within western New York and within the State of New York.
  • spend or incur approximately $5.0 billion in combined capital, operational expenses and other costs in the State of New York over the 10 years following the achievement of full production.

What is full production at this new factory?

According to the same filing, Tesla expects “approximately 1 gigawatt annually beginning in 2019.” In the past, SolarCity has referred to the factory as having a 1 GW capacity with potential for up to 5 GW, but it looks like they are sticking to 1 GW for now.

The production of solar cells to make modules and tiles (for Tesla’s solar roof) will use technologies developed by Tesla (Glass), SolarCity’s Zep and Silevo (modules and connections), and Panasonic for the cells and the manufacturing.

Tesla explains the agreement in the filing:

“In December 2016, we entered into a Production Pricing Agreement: Phases 1-3 (the Phase 1-3 Agreement) with Panasonic Corporation, Panasonic Corporation of North America and Sanyo Electronic Co., Ltd (collectively, Panasonic).  This agreement provides that Panasonic will manufacture custom photovoltaic (PV) cells and modules for us, primarily at Gigafactory 2, and that we will purchase certain amounts of PV cells and modules from Panasonic during the 10-year term, with the intent to produce PV cells and modules totaling approximately 1 gigawatt annually beginning in 2019.”

Panasonic said that it plans to make a $250 million investment in the manufacturing effort.

This deal is somewhat similar to the deal Tesla and Panasonic have at the Gigafactory 1 where they collaborated on the development of a new battery cell, which Panasonic ultimately ends up being the manufacturer under a long-term agreement for Tesla to purchase the output.

In the case of Gigafactory 1, Tesla uses the cells to make its battery packs for cars, Powerwalls, and Powerpacks, while at Gigafactory 2, Tesla will use the cells to make solar roof tiles and modules.

Tesla still expects to start production of the solar roof at Gigafactory 2 in “summer 2017”. The expectations for the product are high since Musk said that Tesla’s solar roof will cost less than a regular roof – even before energy production.
