We have invested some of the profits from the business in solar hot water heating panels and solar photovoltaic panels as a way of offsetting the CO2 emissions from our travel on planes, trains and cars.

The solar hot water system has reduced the annual gas consumption by about 30% (even though it cannot be used to heat water in the central heating system).

The photovoltaics were installed in January 2011 and on the sunniest day so far have produced just over 1.5 kW. The total output from the 8 Sanyo high efficiency hybrid modules in the first year has been 1,435 kWh. The average production over the first full year has therefore been just over 3.9 kWh per day, corresponding to a 30% decrease in electricity consumption from 2010.

In the UK, energy companies are currently committing to provide Feed-in Tariff payments over a 25 year period for solar installations and other suitable microgeneration schemes. This means that the installations are also a medium to long-term financial investment, as well as a contribution to reducing CO2 emissions.

The financial figures for our installation after one year are:

  • Income from generation payment = 619
  • Income from export payment = 22
  • Reduction in expenditure on electricity = 171

  • Net Income = 812

  • Return on investment = 7.1% pa
  • Payback time = 14.1 years
