Solar panel array to run Koi pond pumps
I wish to use solar power to run my koi pond,have been on your solar calculator,and it tells me that i am using 4920 watts per day(pond pump 150 watts 24 hours aday)(air pump 40 watts 24 hours a day)uv light 15 watts 24 hours aday)
what kind of system would i need.many thanks mark
Unfortunately, you would need a huge system to run that - those are fairly powerful pumps, and if they are on all the time they are using a lot of electricity (as you've probably noticed from your electricity bill!).
On an average British day, the power you need could be produced by a solar panel array of approximately 2000 watts. However, you do of course get more power in the middle of summer than in winter. In summer you could produce that power with about 1000 watts of solar panels. In winter you would need nearer 5000 watts of panels to produce enough power.
1000W of solar panels cost the best part of £5000, so even in the middle of summer it would be a very expensive solution!
Sorry not to be able to be more encouraging.
