   The cost of a solar PV module make up the largest part of the total investment costs. As per the recent analysis of Solar Power Generation Costs in Japan 2021, module unit prices fell sharply. In 2018, the average price was close to 60,000 yen/kW, but by 2021 it is estimated at 30,000 yen/kW, so cost is reduced by almost half.

   Experience curve of lithium-ion batteries: the price of batteries dropped by 97% in three decades. [65] [66] The levelized cost of storing electricity (LCOS) is a measure of the lifetime costs of storing electricity per MWh of electricity discharged. It includes investment costs, but also operational costs and charging costs. [67]

4. Levelized cost of electricity - Wikipedia

   en.wikipedia.org/wiki/Levelized_cost_of_electricity

   Electricity market effects of grid balancing may require a load-following power plant to curtail generation of energy if the grid does not demand energy (negative spot prices) or allow a generator with high variable costs to be brought online to dispatch into a grid with significant unmet demand and high spot prices. Battery, run-of-the-river ...

5. Solar power - Wikipedia

   en.wikipedia.org/wiki/Solar_power

   When wind and solar are a small fraction of the grid power, other generation techniques can adjust their output appropriately, but as these forms of variable power grow, additional balance on the grid is needed. As prices are rapidly declining, PV systems increasingly use rechargeable batteries to store a surplus to be used later at night.
