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.
Can solar energy be stored in a battery?
Crucially, adding storage to solar dramatically enhances the value of solar energy. A recent modeling study of a 300 MW solar plant in South Australia found that including an equal-sized battery (300 MW with 2 hours storage) would increase the energy exported to the grid by 33 percent, and boost project revenues by an astonishing 170 percent.
What are residential solar energy systems paired with battery storage?
Residential solar energy systems paired with battery storage—generally called solar-plus-storage systems—provide power regardless of the weather or the time of day without having to rely on backup power from the grid. Check out some of the benefits. This battery system is paired with a residential rooftop solar array in Arizona.
Why is solar energy storage important?
Storing this surplus energy is essential to getting the most out of any solar panel system, and can result in cost-savings, more efficient energy grids, and decreased fossil fuel emissions. Solar energy storage has a few main benefits: Balancing electric loads. If electricity isn’t stored, it has to be used at the moment it’s generated.
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.
How can solar energy storage make your home more sustainable?
Storing energy generated from your solar panels can make your home more sustainable. By saving energy from the daylight hours, you’ll be less dependent on the power grid and even protected in case of a blackout. Let’s explore the technology and recent advances in solar energy storage.
