Determining the Value of Solar Photovoltaic Power Systems

ALBUQUERQUE, N.M. ? Consistent appraisals of homes and businesses outfitted with photovoltaic (PV) installations are a real challenge for the nation?s real estate industry, but a new tool developed by Sandia National Laboratories and Solar Power Electric? and licensed by Sandia addresses that issue. Sandia scientists, in partnership with Jamie Johnson of Solar Power Electric?, [...]

Cut Costs of Solar Power by Reducing Permitting Fees

Solar panels are an investment, even with incentives, tax rebates and the recent falling prices.� Yet, there is one area in which costs of solar power can be reduced – trimming permitting fees and streamlining the process. In order to install residential solar panels, you will need a building permit (and possibly other land use [...]

Variable reluctance starter motor for Stirling engine

I chose to use a variable reluctance motor as the starter for my Stirling engine design for the following reasons: 1. The most important feature is that it offers near zero friction when the motor is not energized. The only sources of friction are the shaft bearing drag and aerodynamic drag on the rotor. This [...]

Are SRECs the Future of U.S. Solar Policy?

By Stephen Lacey, Editor �� SREC-based solar programs are increasingly popular. As pioneering states get more experience, many are wondering if SREC-only structures will win out, or if a hybrid approach will be the best solution. Feed-in Tariffs (FITs) have been a major buzz phrase in solar policy circles in recent years. While dozens of [...]
