Photovoltaic component specification to help reduce solar cell manufacturing costs

Photovoltaic component specification to help reduce solar cell manufacturing costs

Developing standards tailored specifically to the needs of solar cell production, less complex and costly than those used in the semiconductor industry, is one weapon in the battle to reduce manufacturing costs. John Baxter and Al Bousetta from Swagelok discuss a new PV component processing specification that matches testing, cleaning, and packaging steps for stainless steel components.
Wind Power & American Values

Wind Power & American Values

In Zeebrugge, there are a couple of big wind turbines. I didn’t get a picture of it, but as you approach, there’s one really pretty, big old hotel, and you see the giant windmill behind it, and it’s really striking. Above you can see it from a different perspective. On the way home we saw lots more wind turbines along […]
