Calculations

A PV module's or string's rated open-circuit voltage (Voc) is measured at a defined temperature, namely 25 C (77 F). But what happens as temperatures fluctuate As temperature rises, voltage decreases. Conversely, as the temperature drops, voltage increases. What does this have to do with system design To avoid damaging equipment, design voltage needs to stay below an inverter's maximum input voltage, as well as the voltage rating of wiring, switch-gear, and overcurrent devices. The expected...

Some builders in California are experimenting with mixes that contain as much as 50 fly ash and 50 cement, and find they are working very well. Concrete containing fly ash does have some drawbacks. It sets up slowly, meaning that construction might be delayed a day or two after the pour, depending on weather. That is what makes it more water-resistant, however. In cold weather, it may require other admixtures to accelerate the setup time. Crawl spaces are common in many parts of the...

By David Johnston & Scott Gibson illustrations by Martha Garstang Hill Turning an unfinished basement into living space usually involves adding new interior walls. Builders sometimes use 2 by 4s to build a conventional wall and insulate it with fiberglass batts. A vapor barrier applied to the warm side of the wall, or directly against the foundation, is supposed to keep moisture away from the concrete. But moisture that accumulates inside the wall is trapped, which can lead to mold and...

Powering Your Future

I read that for each occupant in a properly ventilated home, 10 to 40 cubic feet per minute (cfm) should be exchanged with fresh outside air.

Though the minimum for a highway-capable vehicle is 96 V, some systems go to 300 V or more. The physical size of the battery volume per volt will determine your top speed, so you'll need to figure out how many volts can fit into the space available and whether that voltage will be enough to reach your desired speed. Look at volume per volt how bulky should the pack be to give me the...
