Batteries for Your PV System: How Much Do You need?

With Tesla’s big stationary storage announcement last week, much attention was paid to how battery prices have fallen faster than expected. The $350 per kWh price for the 10 kWh battery was ahead of most analysts’ forecasts. Not surprisingly, the emphasis has been on using those batteries—at least initially—for backup power and demand charge reductions, but as SolarCity CTO Peter Rive recently noted, they’ll also soon be used for grid-connected solar customers. That […]

Modeling Grid Reliability with the HOMER Optimization Modeling Tool

One of the most common user requests that we have received over the years at HOMER Energy has been the ability to have the grid be unreliable. HOMER was first modified to allow grid-connected systems in 2003, and the grid was treated as basically an infinite energy source. You could play with costs, and over the years the complexity with which HOMER could manage the grid increased. But the singlemost requested grid enhancement […]
