The benchmarks in this report are bottom-up cost estimates of all major inputs to PV and energy storage system (ESS) installations. Bottom-up costs are based on national averages and do not necessarily represent typical costs in all local markets.
solar industry is facing major policy changes in April 2025. The Trump Administration has enforced new tariffs, the EPA is rolling back climate initiatives, and Congress is debating the future of clean energy tax credits.
Adding an energy storage battery to a residential solar panel system typically costs $7,000 to $18,000. The final price depends on what you buy and who installs it.
This robust growth is driven by accelerating investments in renewable energy generation, widespread deployment of utility-scale and distributed PV systems, rising adoption of energy storage and hybrid inverter solutions, and increasing grid modernization efforts to support high.
"A 500 kWh lithium system now costs roughly the same as a 300 kWh lead-acid setup in Jordan – but lasts twice as long," notes Ahmed Al-Masri, a renewable energy consultant in Amman. Current market prices range between $420-$650/kWh depending on configuration and scale:.
