I`ve been collecting data from our solar panels over the duration of 10 years. These are the Evacuated tubes, on a 38 degree south facing roof line, comprising 32 tubes, (Schott), or 16 tubes x 2 panels. This set up heats our water for bathing.
These figures are hours of sunlight activating the controller, so they are based on the average amount of hours worked for each month , (all based over 10 years) starting with January. Figures in hours per month.
Jan:42.5, Feb:75, Mar:150, Ap:211, May:230, J:243, Jl:260, Aug:229, Sep:180, Oc:111.5, Nov:56.6, Dec 35.4 Since living at this house, family of 3, average consumption, (ie no olympic sized baths etc) we used to use around 1200 litres of heating oil per year, this was before putting in the solar panels. Since installing the panels and linking it in with the hot water tank we dropped the consumption of oil per year to between 350 to 400litres . A huge saving.
Incidentaly the cost of all the solar equipment all those years ago was £1500. That was the 2 panels,controller,pipework,pump,sensors, bladder and flow gauge. I hate to think how much it would cost now. Installation was nil as a plumber mate and me did that bit. Its not difficult, just took me months to get my head round its benefits.
In my next thread in due course, I will let you know of my rainwater havesting savings.
I hope you have found this of interest , Mike.
