This report evaluates how solar PV can be used in combination with a battery, a hydrogen storage (including an electrolyser and a fuel cell) and a heat pump to supply the annual heat and electricity demand of a building, without being connected to the grid.
[pdf] The price range for solar batteries is roughly $6,000 to $20,000 NZD. Typically the more storage a battery has, the more it will cost. Other factors that affect the price are the capabilities of the battery, quality of the battery, chemistry used and how long it’s expected to last.
[pdf] The EnerC+ 4MWH containeris a modular fully integrated product , consisting of rechargeable lithium-ion batteries, with the characteristics of high energy density, long service life, high efficiency. It can provide stable energy release for over 2h when the batteries are fully charged.
