“The microgrid is already generating value for STCH by providing resilient, renewable power for part of our campus,” La Follett said. “And by exporting power to the local grid, we are generating economic benefit. But more importantly, this environment gives us the opportunity to test different ideas and strategies as we work to understand the operational envelope of these different components. One of the things that makes this microgrid unique is the diversity of the components that are involved. We wanted the flexibility to test numerous combinations of distributed energy resources.”

Danny, the panels aren’t usually the issue, it’s the inverter that needs to be compatible for energy storage.

Figure 2: The voltage waveforms on the DC and AC sides of the inverter. Note that in a transformer-less system, the DC side does indeed have a DC voltage corresponding to the output of the photovoltaic cells between the PV+ and PV- nodes (this may be increased by a DC-DC converter) but each of the PV nodes also has an AC voltage whose peak value is similar to the peak output voltage of the AC side. If not considered at the system level, this represents a serious safety hazard.

The agreement with Tenaska further diversifies Capital Dynamics’ growing solar portfolio. The company’s Clean Energy Infrastructure team is the second-largest owner of solar projects in the United States and manages approximately $4.9 billion in assets and 3.1 GW capacity in its current portfolio.

China is now home to the largest floating solar farms in the world, concentrated in Anhui Province atop flooded former coal mines. The biggest floating solar farm can produce 150 megawatts (MW). Estimates vary widely on how many homes one megawatt can power based on a variety of factors such as geography and weather, but the California Energy Commission pegs the number at 750 homes. Our advanced math skills tell us that a 150-megawatt solar power plant can support about 112,500 residences. Of course, China is not California, so either double or half the number, depending on your personal biases.

While China’s PV policy announcement dominated the headlines in Q2 2018, there were a lot of other significant happenings in the world of solar, not least the EU’s 32% renewable energy targets, rumors of U.S. tariffs on inverters, PV records in Germany, and unexpected new partnerships. Read on to discover the highlights from April to June.

Apex Microtechnology’s SA110 (Fig. 4) is a fully integrated half-bridge SiC power module. It provides up to 20-A continuous output and can operate at over 250-kHz speeds. Its protection features include undervoltage lockout (UVLO) and active Miller clamping.

I am pleasantly surprised at the functionality of this unit. It is remarkable flexible in several ways. The input voltage may vary from 100 to 550 VDC, with the maximum DC voltage listed as 600 VDC. That’s quite impressive, if you have your druthers, you’d always want to be on the high side of 350 VDC to drive a 240 VAC inverter, but the lower limit of 100 VDC means you could conceivable drive this unit with lead-acid batteries. I understand that you can sometimes buy used golf cart batteries cheaply, which with a little bit of desulfating, and keeping the charge above 50% can last a long time. Anyway, the huge amount of voltage flexibility is wonderfully resistant to changes in battery technology over the decades. If the best, as in cheapest per kWh batteries end up being huge cells, sort of like lead acid batteries instead of the many small cell, high voltage batteries we envision today, you are ready for it. The unit can operate at 50, or 60hz, meaning it will work in Japan, or Europe, as well as North, and South America. Presumably, the unit can also serve as a charger for the batteries, so that price arbitrage can be done with any spare battery capacity. I noticed the unit has 2kW of what the specs call “secure power”, which I take to mean uninterruptible power. If I had one of these, my LED home lighting(but not lamps powered from outlets), my networking equipment, computers, and mobile charging would all be powered by this circuit. The “normal” circuitry of the home will be connected directly to the utility service, and even if you have automatic switch over in case of utility failure, you will see transients, and if there was some sort of failure of switch over, it would be nice to have lighting, and digital communication running no matter what. The inverter, and battery unit are AC coupled, which makes using different types of batteries much simpler/cheaper, but results in a bit lower efficiency compared to DC coupling. For DC coupling, you’d have to have some sort of DC to DC converter to maintain the huge DC voltage range, which would lose any increase in efficiency. On the other hand, the engineer in me likes the simplicity of having the input to the inverter, capacitors for high momentary demand, the output from the solar MPPT circuitry, the output from the rectifier connected to the utility service, and the batteries all sitting on one big DC buss. Of course, for this the batteries would need to be designed for the inverter/battery control unit, at least as far as DC voltage range. I can’t wait to see what these will sell for. Since one design works pretty much everywhere on the planet, and with any batteries, I would think mass production would let it be sold at a reasonable price.
