Solar panel packages have different levels of power. For instance you can get a kw system but is this kw per hour or day. How does this work?
That means if you stick a watt meter on the output when there is maximum design sunlight on it you will get kw. If you shine the maximum design sunlight on it for hour then you get kw hour of power. In one day you get 24kw hours assuming you can get 24 hours of maximum design sunlight. Your home electric bill is typically in kw hours. At the macro level power is traded at megawatt hours.
it would be an instantaneous rating at maximum output. To get the the amount of power produced, you would multiply the number of hours at near peak output. kw X 5 hours = 5kwh or about 50 cents of electricity.
kW is the unit of measurement used. kWh means you have kW steady for an entire hour. In the case of solar panels, say you are using 00W panels. That means at any given time assuming ample sunlight is hitting the panel, it is producing 00W. You wanted a kW so you will need ten panels at 00W (less or more depending on the rating of the panel) this will give you kW. That means at any given time you can get as many watts as needed up to kW (000W). Say the sun hits the panels for eight hours a day, you will have kWh each of those eight hours, or 8kWh per day. Unless you have a system of batteries to capture unused power, you will only be able to use up to kW (000W) at any given time, any unused power will be wasted. Solar panels alone are not like a generator, they do not slow down or speed up depending on demand. Even with no load on them, they will produce as much power as they are able, and without batteries that power is lost. To simply answer your question, if you get a kW system, that means kW per hour.
A kW is an on the spot degree of means. A kWh is a level of means produced via the years. A KW array produces an on the spot means of 000 watts. whether that could be a 2V panel which skill it produces eighty 3 amps of modern-day. In 3 hours it produces 3kWh (kilowatt hours) of electrical energy, no longer 3kW. A 3kW 2V array might produce a similar quantity of electrical energy in one hour at 079 amps.
