How Was Renewable Production Able to Surpass Nuclear Power?

In March, renewables provided 21.6 percent of the nation's net electricity generation compared to nuclear's 20.34 percent. In April, that lead jumped to 22.98 percent compared to 19.19 percent from nuclear.

Is solar power in nuclear disaster exclusion zones advisable?

ARNOLD GUNDERSEN for Bulletin of the Atomic Scientists:  My own experience near solar arrays in Fukushima Prefecture indicates that the problems of building and maintaining solar installations in a contaminated nuclear wasteland are over-simplified, and worse, totally ignored. One of the greatest burdens of maintaining operating atomic reactors is the cost of working in a Radiologically Controlled Area. (The Lawrence Berkeley National Laboratory defines a Radiologically Controlled Area as: “Any area to which access is managed to protect individuals from exposure to radiation or radioactive materials. Individuals who enter Controlled Areas without entering Radiological Areas are not expected to receive a total effective dose equivalent of more than 0.1 rem (0.001 Sievert) in a year.”) Each nuclear power plant operates with specific instructions and constraints, with Radiation Work Permits tailored for each specific maintenance activity. Because special clothing, special respiratory equipment, and special radiation monitoring equipment are routinely required to perform even minimum maintenance activities inside a nuclear power plant, every activity takes longer, costs more, and requires more people inside each reactor than necessary in any other industrial setting. Consequently, the question becomes: Does building solar panels on land contaminated with nuclear waste resemble work in a normal industrial setting, or is it more similar to work inside a radiologically contaminated atomic reactor—at significantly higher cost?   Full Article:

Joyce Dayton Corp - Solar Tracking Drive Solutions

Joyce Dayton Corp - Solar Tracking Drive Solutions

Joyce Solar Actuators are designed to precisely position smaller solar tracking equipment. Their robust and efficient DC motor (24V or 36V) keeps power consumption to a minimum. Travel speeds remain nearly constant regardless of the load. Ideal for rugged environments common to the solar industry, these cost-effective SA actuators have an IP65 protection rating. Self-locking features in the mechanism ensure that the solar actuator will hold position throughout the daily tracking cycle. Specifications: • Double clevis mounting for easy installation • Clutch for overload protection • Adjustable limit switches for flexible travel settings • Reed sensor digital feedback for accurate positioning • Duty cycle is 25% (4 min. running, 12 min. rest) • Lubricated for life
