In part two of our three-part series, we covered the support features that our Sunny Tripower three-phase inverters and Sunny Boy single-phase inverters have that implement proactive responses to grid requirements. Frequency Ride-Through and Voltage Ride-Through in particular are crucial for the definition of operation ranges of the inverters and the expected response for different levels of anomaly in the voltage or natural frequency of the grid.
Over the last few years, distributed generation systems, such as PV, have grown rapidly throughout the country. Every day there are more and more systems integrated to the grid. However, with the growth and increased penetration of distributed energy systems (DERs), new challenges arise. This three part series will look at the best solutions to overcome these challenges.
On Monday, November 30, 2015, the World Climate Summit negotiations will start in Paris. The goal: a world climate agreement to reduce global warming before it’s too late. Up to now, international climate policy has meant no more than minimal consensus. No surprise that expectations for a breakthrough in Paris are subdued. And yet, the chances for successful negotiations are not so bad, after all.
The Sunny Boy TL-US line of inverters with Secure Power Supply is now more efficient and easier to install.
Hawaii’s concerns with its exceedingly high levels of distributed power generation are nothing short of well-documented. As a result, Hawaii’s solar market came, according to some local installers, to a screeching halt and people from across our industry quickly began searching for solutions to get solar installs back on track.
Solar has become the new norm and can be seen on rooftops and in large-scale commercial projects all over the world. It has become a key component in many fascinating projects that might give us a sneak peak at what the future holds. Here we’ll introduce five interesting solar projects that push the boundaries of technology.
More and more Americans are using photovoltaics to become independent from rising electricity prices. However, most of them are no longer purchasing their PV systems; instead, they are choosing a complete solar service package, an option that is also referred to as solar leasing. Leasing instead of buying–a business model that established itself in the automobile industry years ago–could also become a worldwide model for success in the solar sector. Discussing this option below are Edward Fenster, co-founder and CEO of Sunrun, a pioneer in the solar leasing business model, and Bates Marshall, vice president of the medium power solutions business group at SMA America.
Think Google Maps for solar. This is what the Australian PV Association (APVA) plans to produce. The APVA is investing in an interactive solar mapping web interface and working in collaboration with utilities, policy stakeholders and universities to execute the project. The map will combine 3D solar modelling with layers of data to identify potential PV areas, demonstrate PV generation and track the growth of solar across Australia.
Homeowners, installers, utility providers, city planners and local policy makers can all benefit from the data acquired from solar maps, but can Australia capture the real potential of this tool to develop a sustainable solar marketplace across the country?
It is an early fall morning at the SMA America manufacturing facility located in Denver, Colorado. I have my personal belongings packed away in my car and am anxiously awaiting the arrival of my SMA America off-grid colleague and battery-based inverter expert, Roy Dyngen.
Tokelau is one of the world’s most remote countries – and the first to generate its energy supply using only photovoltaics. We spoke with Alexander Kaemmerer of SMA Australia, who spent almost a month in Tokelau supporting the project, training Tokelauans to operate the plants and demonstrating to the clients how to proceed with the rest of the commissioning.
