Earning overtakes Spending

19 May: On the Peveril Metering spreadsheet, I keep a track of the electricity cost and PV generating income since First of January 2010. The Feed in Tariff didn't come in till April 1st, but once it did the growth rate changed and the two columns were transformed. At £ 435 pounds, on May 19th, the Earning column overtook the Spending, galloping past it, with the summer to come, so consumption reducing and power generation increasing. There will be a closing up again as winter sets in, but no catching up!
  In 2011, the two horses will start more equally, with the Feed in tariff in place and the Sunboxes making their contribution to reduce the consumption.
