Renewable Energy Group began in 1996 as the biodiesel division of West Central Cooperative with the construction of a plant in . In 2006, the company separated from West Central and moved its headquarters to Ames. In 2013, the company acquired -based biofuels company Syntroleum Corporation amid that company's struggles for profitability. In 2015 it acquired the assets of -based.

[pdf] You have the option to purchase renewable electricity, either directly from your power supplier, from an independent clean power generator, or thro. .
Some power companies provide an optional service, called green pricing, that allows customers to pay a small premium in exchange for electricity generated from clean, renewable. .
In some parts of the country, you can choose not only how your electricity is generated, but also who generates it. Just as the long-distance telephone industry was restructured,. .
Buying green certificates allows you to contribute to the generation of clean, renewable power even if you can't buy clean power from.
[pdf] Modules connected in seriesform strings, and strings can be connected in parallel to an inverter. The electrical current through all the modules of a string must be the same. By contrast, the voltage of parallel strings must be the same. As we saw in the last section, a shaded module in a string can bring down the power. .
Bypass diodes are devices within a module that allow the electrical current to “skip over” shaded regions of the solar module. By using bypass. .
MLPEsare devices that are attached to individual modules to increase performance under shaded conditions (though there are other.
[pdf] The main support tower is made of steel, finished in a number of layers of protective paint to shield it against the elements. The tower must be tall enough to ensure the rotor blade does not interfere with normal day-to-day operations at ground level (for instance with turbine shadow flicker). A smaller, on-shore 2MW wind. .
The nacelle is the ‘head’ of the wind turbine, and it is mounted on top of the support tower. The rotor blade assembly is attached to the front of the nacelle. The nacelle of a standard 2MW onshore wind turbine assembly weighs. .
The rotor blades are the three (usually three) long thin blades that attach to the hub of the nacelle. These blades are designed to capture the kinetic energyin the wind as it passes, and.
[pdf] There are two types of inverters used in PV systems: microinverters and string inverters. Both feature MC4 connectors to improve compatibility. In this section, we will explain each of them. .
Planning the solar array configuration will help you ensure the right voltage/current output for your PV system. In this section, we explain what these items are and their importance. .
Now, it is important to learn some tips to wire solar panels like a professional, below we provide a list of important considerations. .
Up to this point, you learned about the key concepts and planning aspects to consider before wiring solar panels. Now, in this section, we provide you with a step-by-step guide on how to wire solar panels.
