SolarWorld: bankruptcy status, trade case, and warranties

solarworld bankruptcy trade case

SolarWorld Industries GmbH (formerly SolarWorld AG) is a major player in the solar panel manufacturing space, and the company has had a year full of change. After it declared insolvency earlier this year and went through a reorganization and acquisition process, the company joined manufacturer Suniva to petition the government for tariffs against imported solar panels. Now, you may be wondering how SolarWorld’s financial standing impacts the coverage on their solar modules. In this article, we will look back at SolarWorld’s turbulent year and where they stand now, and we’ll examine their updated warranty offerings and consumer protections.

Tesla solar roof cost vs. solar panels: worth the premium?

tesla solar roof vs solar panels

This past spring, Tesla announced pricing for their new solar roof product, a roof replacement for your home. The new solution requires that you replace your existing roof with Tesla’s blend of non-solar glass tiles and solar-enabled glass tiles. It is an elegant new product, designed with great aesthetics, and due to its immense popularity, we wanted to explore the question: does installing this new roof make financial sense for your home? After initial analysis, we’ve found that for the majority of homeowners the answer is “not yet.” Unless you’re in the market for a roof replacement, Tesla’s new solar roof is simply too expensive for the average American homeowner to justify as a home energy upgrade.

The Tesla roof: when will it be available and should you wait for it?

should I wait for tesla solar roof

For those asking themselves, “should I wait for the Tesla solar roof?”, you are not alone. Elon Musk, co-founder and CEO of Tesla Motors, has a well-earned reputation for creating innovative 21st-century products that combine attractive designs with exceptional performance – and generate high levels of consumer interest as a result. The latest Musk technology to make a splash is the Tesla solar roof, which he revealed to great fanfare in October 2016. Here’s everything you should consider before making your decision, including what Tesla roof rivals you should consider.

Should you buy grape solar panels from Costco or Home Depot?

Grape Solar panel kit review EnergySage

Installing solar panels is fast becoming a home improvement project that any homeowner can take on. Now that you can buy solar panels at Costco and Home Depot, you may even be considering installing a home solar energy system yourself. One of the most popular DIY options is to purchase a solar panel kit from Grape Solar, an Oregon-based solar panel manufacturer whose products are for sale at Costco and Home Depot. But before you make a Costco solar purchase, we recommend you learn more about how Grape Solar panels compare to other solar panel brands.

How to make solar panels more efficient

high efficiency solar panel manufacturing

Not all solar panels are created equal. EnergySage uses a classification system for solar panels based on performance, quality, durability and warranty to help solar shoppers compare the quality of all of their options. A solar panel’s efficiency (how effective a panel is at converting sunlight into electricity) is a key factor determining solar panel quality, and manufacturers are constantly improving their processes to create higher-efficiency solar panels.

What are the most efficient solar panels on the market?

most efficient solar panels on the market energysage

For those looking for the most efficient solar panels for their PV system, the first thing you need to know is how to compare efficiency metrics for different manufacturer brands. Simply put, efficiency (expressed as a percentage) quantifies a solar panel’s ability to convert sunlight into electricity. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings, the more efficient panel will produce more electricity than the less efficient panel.

In practical terms, for two solar panels of the same physical size, if one has a 21% efficiency rating and the other has a 14% efficiency rating, the 21% efficient panel will produce 50% more kilowatt hours (kWh) of electricity under the same conditions as the 14% efficient panel. Thus, maximizing energy use and bill savings is heavily reliant on top tier solar panel energy efficiency.

Solar Panel System Design: How Solar Installers Map Out your PV System

solar panel system design

The process of of how solar installers design a solar energy system is often a mystery for most consumers. Because of this, we would like to give you some insight into how solar installers design a solar power system for your home or business. A solar power system is designed considering two important factors – the amount of space that you have available for installing solar panels and the amount of electricity you consume annually. Other factors, like shading analysis and the efficiency of solar panels and inverters also come into play.   Continue reading

Tesla’s Solar Panel Roof: Solar Glass Tiles are New Solar Shingles

If you’ve found it difficult to stay up to date on the future of Tesla Motors and SolarCity in recent months, you are not alone. Numerous industries (solar, electric vehicles, and ridesharing, to name a few) worldwide are starting to feel the impact of a merger that could significantly alter growth plans for manufacturers and executives across the globe. Now the concept of an integrated solar glass shingle – the Tesla solar tile – is on everyone’s mind. 

We had already heard about Tesla’s plans for total clean energy integration – a one step carbon reduction process that involves pairing solar panels with your Tesla electric vehicle. Now for the latest: with Tesla’s highly anticipated solar roofing product, we’ve seen the future of PV roofing and the future of Tesla. One thing is certain: building-integrated photovoltaics (BIPV) are going to be a big part of Tesla Motors – or should we say Tesla Energy’s – future.
