Hi All, Wondering if anyone would have a simple spreadhseet to show the amount of batteries and storage needed for a 5MW solar PV system. I am looking to demonstrate to a client that it is not financially viable and he needs to export rather than on site storage/Use.
There are several more pieces of information required:
1) What is the likely output profile of the solar panels where you are located? If you are in the UK for a 5MW peak system you may only average 1MW. If you are further south the average will be somewhat better.
2) What is the load profile? What is the expected average load? if it is more than the average output above where will you get the additional from?
3) The difference between peak output and minimum load will give a maximum charging rate for the batteries. The time this will last will give the required capacity.
4) Will the maximum discharge rate be higher than the maximum charge rate. If so this will also affect the costs.
Given the required capacity and maximum charge/discharge rates you can then contact battery system suppliers for cost estimates.
