Are rooftop solar panels or battery energy storage systems worth the cost?Pacific Northwest National Laboratory (PNNL) researchers are here to help. Homeowners must navigate a quagmire of complicated policies to determine whether the energy savings from rooftop solar panels or battery energy storage systems (BESS) are worth the high upfront cost.
Are rooftop solar and battery energy storage a barrier to adoption?Even with the benefits of rooftop solar and battery energy storage, the upfront cost of these systems is still a barrier to adoption. In some cases, especially for BESS, the time it takes for a homeowner to recoup the cost of the system with energy savings is longer than the lifetime of the technology itself.
Where do rooftop solar and battery installation data come from?The rooftop solar and battery installation data featured in this report is sourced from our data partner for these Rooftop Solar and Storage reports, SunWiz, with supplementary data from Green Energy Markets – the Clean Energy Council’s data partner for our annual Clean Energy Australia report – referenced in some instances.
What is a battery energy storage system?This is where Battery Energy Storage Systems (BESS) come in. When paired with rooftop solar, BESS transforms a passive energy generator into an active, intelligent energy resource. Figure 1: Battery Energy Storage System with a commercial rooftop solar setup The Need for Storage: More Than Backup Solar generation is inherently variable.
