Solar Power Game-Changer: “Near Perfect”

Solar_Panel_Coating

Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy. By developing a new antireflective coating that boosts the amount of sunlight captured by solar panels and allows those panels to absorb the entire solar spectrum from nearly any angle, the research team has moved academia and industry closer to realizing high-efficiency, cost-effective solar power.

“To get maximum efficiency when converting solar power into electricity, you want a solar panel that can absorb nearly every single photon of light, regardless of the sun’s position in the sky,” said Shawn-Yu Lin, professor of physics at Rensselaer and a member of the university’s Future Chips Constellation, who led the research project.  “Our new antireflective coating makes this possible.”

Solar Goes High-Tech-Cool!


EnPhase Energy Micro Inverter
Enphase Energy announced that it has raised $15 million to ramp up production of its microinverters, a design that they claim significantly boosts the power output and reliability of solar panels.

Enphase Energy has designed a Micro-Inverter for residential and commercial applications. A DC to AC inverter for each module? Solar panels are already way too expensive, so what is the benefit to having an individual inverter?

As it turns out, I see a HUGE benefit to this technology. Number one is Shading! It is amazing to watch an array of panels be brought to its knees by a simple tree branch shading one corner of a single panel. Partial shading of even one cell will reduce its power output. Because all cells are connected in a series string, the weakest cell will bring the others down to its reduced power level. With the Enphase Energy Micro-Inverter, only the panel that is shaded is affected.

Now here is where the cool comes in. If you are like I am, “Love the techy stuff,” you are going to love the advanced analytics and visualization software that comes with the inverters.
