The Bright Idea Behind Power Classes

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.

IBM Uses Machine Learning to Boost Solar for Dept of Energy

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.

The future of solar Feed-in Tariffs in the UK

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.

Geothermal Heating and Cooling

Geothermal heat pumps are ideal for use in buildings looking to reduce consumption to net zero.

A Proven Approach To The Challenge Of Building A Leak-proof Array

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.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
