The
solar-plus-storage market is evolving rapidly and will look completely
different a decade down the road. What can we expect on the way to 2030? Here
are 10 predictions.
All-in-one systems will be the new normal
1.
Lots of storage
Batteries
will be incentivized or mandated for practically every new solar PV system
across the U.S. by 2025. As more homeowners and businesses deploy PV
systems to reduce their electricity bills and ensure backup power, simple net
metering will increasingly be replaced by time-of-use rates and other billing
mechanisms that aim to align power prices with utility costs. We already see
these trends in California and several states in the Northeast.
2.
System costs will increase with the shift toward batteries
Solar systems with
batteries are going to be about twice as expensive as traditional grid-direct
installations, so in that sense, we will see actual costs increase as the mix
shifts toward batteries. But while system costs will go up, we need to be
careful to parse the actual equipment and soft costs from the consumer’s cost
net of tax credits and incentives. Equipment costs for batteries and other
hardware are generally flat to slightly down.
