Dear Community,
I'm new on ThingSpeak for nearly 4 weeks and I'm struggling to compute some MATLAB data. Mostly because I don't know the syntax.
I have a hourly graph of solar production in kW, I'm taking a sample every 20 seconds, and I would like to aggregate the data on a daily basis in kWh.
I guess I need to select the last 7 days of data using some thingsread function, add the data into an array and compute the daily data into an average/sum ... As you can see, I mostly got the mechanics but I'm struggling to create the car ;) Is there anyone kind enough to assist me ?
Thansk a lot !

Solar power is the fastest growing form of renewable energy. One challenge is that is requires sunlight, which means once the sun sets, you don't generate power. Energy storage (large battery packs) is one solution to capturing excess power during daylight for use during night time. Recently, Design News covered Tesla's Megapack energy storage solution. I think this is a great example of what needs to be done, to be sure, other companies are providing similar solutions, like NEC Energy Storage .

These systems have another benefit, too. They are a fast-acting form of dispatchable power , that along with renewable power, can provide stability to the power grid.

Please share your thoughts on grid-level energy storage. Is it a key component or nice to have?
