4 FAQs about Rooftop home energy storage

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.

What is rooftop solar power?

Rooftop solar power, also known as rooftop photovoltaic (PV) systems, refers to solar panels installed on residential or commercial building rooftops to generate electricity. These systems convert sunlight directly into electrical energy through photovoltaic cells, providing clean, renewable power for your home or business.

Is rooftop solar a viable energy solution in 2025?

Rooftop solar power has transformed from a niche technology into a mainstream energy solution, with over 4.4 million American homes now powered by solar panels. As we enter 2025, technological advances, improved financing options, and strong federal incentives have made rooftop solar more accessible and cost-effective than ever before.
