While other solar forecasting systems take more narrow location and timeframe views, what's different about the IBM approach is that we incorporate a great number of weather and solar energy prediction models. We then blend those using historical data as a function of weather situation, forecast horizon and location to create what we call a supermodel.
We're extremely close to reaching the point at which renewable electricity costs as little to generate as electricity from fossil fuels, so it's imperative that we don't take a backward step.
The current suggested guideline by the NRCA (National Roofing Contractor Association) for the installation of a PV system on a steep slope asphalt shingle roof as far as the flashing of the PV system stanchions, shows the metal flange to be applied underneath the roofing paper.

There have been enough successful low-income solar pilot programs at the state and federal level that it is now possible to launch a larger initiative with confidence that it can succeed.
AltEnergyMag.com has once again partnered with Intersolar to bring all the industry news and exciting new products to help our readers make sense of this key tradeshow. Here we have compiled a list of some product releases from this years show.
News and Product Announcements from InterSolar North America 2015
The use of a tracking system for a utility-scale project not only reduces LCOE, but also provides more usable power by broadening the power production curve to provide a smoother flow of energy from dawn to dusk.
PVWatts performs simplified PV system performance calculations using information about the array's geographic location, orientation, and a set of user-input loss factors
Solar power was particularly efficient when combined with ground heat in terms of the profitability of investments.
A solar powered water system is one of the easiest solar power systems to install and will ultimately save you time and money.
Pay too little and you risk a dodgy product and no after-sales service. Pay too much and you'll end up waiting 10 years just to recoup your cost!
TRA Snow and Sun modifies Solar Tile Mount to adjust vertically for use on S-tile tile roofs to provide adequate air flow between solar panels and the tile roof.
Two states recently passed legislation that would require significant increases in renewable electricity generation.
With solar on the cusp of economic feasibility in many areas, incremental cost reductions such as those offered by digital inkjet printing technologies can make the difference between moving ahead with solar and sticking with electricity from the local utility

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
