Since the tank is heated by a solar water system and the average amount of sun shine per day is 8H a day. Do I just then use the figure of 8H for all calculations ?
Thank you for all the feedback guys. It helps my approach to this calculation is not from a energy generating point of view but after the fact, analyze the amount of power it toke to heat the water from x to y. So I won't have the time. You arrive and see the max temp in the tank and use room...
Nasu.
You just did the exact same calculation as I did in the original post and came to the same answer. 12v 65Ah. So I don't understand what was wrong then in the first place ? I'm just using a battery as an example can be a power supply capable of delivering the same current.
I understand your point and appreciate there won't be a unique answer if no time is allocated but to complete the formula let's say I measured in 60 minutes the water temp changed from 20 to 30 degrees via the solar system and the tank was 100% insulated. What would the required battery...
The problem is I can't give a time as I don't have it. I can for argument sake I pick a time frame of an hour but it's not realistic. the application is as follows . If a solar hot water heat collector heats up 10L of water from x to y in a average day of sun 6-9 hours. What is the equivalent...
Hi Nasu
Thank you for the feedback
How would I go about calculating this then ? The time required to heat the water is irelevent to me. If it takes 8 hours then It takes 8 hours. Just trying to find the formula to calculate how much power or voltage/ current it takes or toke to heat water from...
Hi Guys
I'm new the PF and hope I'm posting I the correct place, apologies to admin if not ;-). I'm working on a project at home and maths is not my strong suit. I have an equation that I need to complete and involves converting thermal heat capacity in water into electric power. From what I...
