Have you considered a whole house solar system? This could run your house and pump.Thks flameport , well after those calcs , if i end up forking out 4 to £500 quid on a solar system , i would get my money back in 2 or 3 yr of running pump yeah. mmmm kinda swaying back to a solar system ... hee hee, true regards thks for your time j
Worthwhile solar power for 6 months of the year? I have had 1,080kWh from mine already this year. Hardly worth it I guess.
