The majority of sectors within the solar energy industry are still exhibiting lower than optimal bottom line margins. However, certain sectors are now beginning to see slight margin improvements generated from continued improvements in balance of system costs, industry consolidation and continued growth for solar in certain geographies.
In order to avoid costs for AC panel upgrades, it makes sense for inverter manufacturers to provide power classes that get the most solar power on an existing customer's AC panel without upgrading it.
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.

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.
