What commercial solar project managers need to know to add storage to their offerings

August 20, 2019 | 103 views

With many solar companies getting involved in storage projects, it is crucial that the project team understands the differences between the two technologies. Good project managers use their previous solar experience to anticipate risks that could derail their commercial solar-plus-storage budgets and schedules. The Flux Energy Systems team has worked on hundreds of solar projects and dozens of battery projects. Through that work, we have identified how key differences in the technology shape critical project decisions.

A vision for renewable energy

Article | September 17, 2022

Right now, renewable energy makes up a very small part of the entire energy sector of Bangladesh. But as we move into the future, and concerns about the environment become too great to ignore, exploring cleaner and greener sources of energy becomes the need of the hour. Our economy is booming, and our population is growing, so it goes without saying that our energy requirements are immense. There is plenty of scientific evidence that burning fossil fuels indiscriminately is not sustainable in the long term, so we do need to up our game in looking at alternatives.

2020: The Year of Convergence in Corporate Renewables

Article | June 14, 2022

The rapid growth of corporate renewable procurement has been nothing short of a buyer-driven revolution in the United States’ electric sector. Almost 20 gigawatts (GWs) of corporate power purchasing agreements (PPAs) were completed in 2019 across the globe, up from 13 GWs of corporate PPAs in 2018 and triple the numbers from 2017.1,2 And the majority of this growth has come from the United States. Fortunately for those of us committed to renewable energy, we expect this trend to continue. But as should be expected in such a dynamic, buyer-driven sector, we are starting to see some noticeable shifts in the marketplace as it evolves and grows. I wanted to highlight some of the trends Constellation is watching for this year.

2020 Trends That Will Make Waves In The Energy Industry

Article | July 16, 2022

In the renewable world, energy is generated by weather and the amount of energy that can be produced depends on the current conditions. Energy storage can ensure a power supply is maintained when weather conditions are not optimal for generating energy. While energy storage products have already been introduced to all levels of the market there are several technology hurdles to overcome before energy storage will reach maximum potential. We believe there will be great advancements in 2020 on:

Solar Power, Great For The Environment? Or Is It The Last Thing We Need?

Article | February 10, 2020

Solar power is an undeniably a green, renewable form of electricity generation - but many organisations with questionable motives (even here in New Zealand) are trying to persuade the public (and Government – hi lobbyists!) that solar power isn’t that environmentally friendly, and that it's even harmful. At the expense of bullish corporate profits, solar power is often thrown under the bus. This article lists the facts - putting an end to the negative spin on solar so often found in the media. When solar panels produce power, they do not; create any air pollution, use zero water, create carbon emissions, noise pollution, and they won’t disturb surrounding ecosystems. Solar power is a renewable energy source, the sun’s rays are infinite, fill your boots.

Power Integrations Launches 900 V GaN Flyback Switcher ICs

Power Integrations | March 21, 2023

Power Integrations, the leader in high-voltage integrated circuits (ICs) for energy-efficient power conversion, today announced a 900-volt gallium-nitride (GaN) extension to the company’s InnoSwitch3™ family of flyback switcher ICs. The new ICs, which feature the company’s proprietary PowiGaN™ technology, deliver up to 100 watts with better than 93 percent efficiency, eliminating the need for heat sinks and streamlining design of space-challenged applications. InnoSwitch3 designs also offer exceptional light-load efficiency making them ideal for providing auxiliary power in electric vehicles during low-power sleep modes. The AEC-Q100-qualified InnoSwitch3-AQ family is particularly suitable for EVs based on 400-volt bus systems where the 900-volt PowiGaN switch provides more power and increased design margin―required for 12-volt battery-replacement systems―with enhanced efficiency over silicon-based converters. “The dominant bus voltage for electric vehicles is 400 volts,” stated Peter Vaughan, automotive business development director at Power Integrations. “EV manufacturers are optimizing their new generation of 400-volt systems and re-engineering various power stages in the vehicle, such as the on-board charger. The 900-volt PowiGaN switch is extremely beneficial because it easily accommodates inductive noise spikes, yet it can operate from as low as 30 VDC, enabling systems to meet functional safety active discharge requirements. The extra power delivered by our GaN technology matches the increasing power demands of EV manufacturers, moreover, efficiency in power conversion―even in auxiliary systems―is important for both range extension and thermal management.” In the industrial space, extra power and increased efficiency are extremely advantageous in applications such as appliances, three-phase motors and auxiliary power supply units (PSUs) in servers. The new 900-volt parts are pin-for-pin compatible with existing 725-volt and 750-volt InnoSwitch3-EP parts and offer increased safety margin which is ideal for countries with unstable line voltages. “Our ability to deliver GaN parts rated at up to 900 volts demonstrates the reliability and ruggedness of our PowiGaN technology,” stated Silvestro Fimiani, senior product marketing manager at Power Integrations. The new 900-volt InnoSwitch3-EP and InnoSwitch3-AQ off-line CV/CC flyback switcher ICs employ synchronous rectification, a valley switching discontinuous conduction mode (DCM) and continuous conduction mode (CCM) flyback controller. FluxLink™ communication technology enables the IC package to bridge the isolation barrier, optimizing efficiency and eliminating the need for optocouplers. PowiGaN technology enables InnoSwitch3-EP ICs to deliver up to 100 watts (230 volts alternating current [VAC] plus or minus 15 percent) without heat sinks. InnoSwitch3-EP devices incorporate multiple protection features including line over- and under-voltage protection, output over-voltage and over-current limiting, and over-temperature shutdown. Devices are available with standard and peak power delivery options. Automotive InnoSwitch3-AQ devices can also deliver 100 watts from a 400-volt bus and provide performance and protection features similar to those of the popular 1700-volt silicon-carbide InnoSwitch3-AQ ICs currently used in 800-volt EV systems. Availability & Resources Pricing for the new 900-volt GaN InnoSwitch3-EP devices for industrial applications start at $2.00 for 10,000-unit quantities. For the InnoSwitch3-AQ automotive-qualified devices or further information on all Power Integrations’ solutions, contact a Power Integrations sales representative or one of the company’s authorized worldwide distributors: Digi-Key, Farnell, Mouser and RS Components, or visit power.com. About Power Integrations Power Integrations, Inc. is a leading innovator in semiconductor technologies for high-voltage power conversion. The company’s products are key building blocks in the clean-power ecosystem, enabling the generation of renewable energy as well as the efficient transmission and consumption of power in applications ranging from milliwatts to megawatts.
