1. Emerging battery technologies
There’s a strong push toward new battery chemistries (solid-state, sodium-ion, zinc-based, graphene-enhanced etc) that may outperform today’s lithium-ion batteries in cost, safety and lifespan. builtin.com
Why it matters: For solar + storage systems this means cheaper, longer-lasting storage units, which in turn makes renewables more viable and grid-independent.
Tip: If you’re considering solar + battery installation, keep an eye on warranty and future upgradability (so you can swap in newer battery tech later).
2. Tariffs on Chinese solar cells / batteries in the U.S.
Joe Biden’s administration announced new tariffs on imports from China that include EV batteries and solar equipment. AP News
Why it matters: This kind of trade policy can affect global supply-chains, cost of solar + battery systems, and thus what you pay locally.
Tip: If you’re sourcing solar + battery equipment in India (or South Asia), check origin of components — tariffs or supply-shocks abroad may ripple into pricing locally.
3. Solar plus second-life battery storage for EV-charging infrastructure in India
In Bangalore, India, a pilot project: a rooftop solar PV + 100 kWh BESS made of repurposed “second-life” EV batteries to power a charging hub. ETAuto.com
Why it matters: It shows a mature model where solar + battery storage + EV infrastructure integrate — and using second-life batteries helps cost and sustainability.
Tip: For your solar system at home (or small business), consider whether “second‐life” battery options might be available locally — potentially lower cost, though check warranty & safety.
