Given that honey is produced from sunlight (photosynthesis), and concentrated by bees, I thought that it would be interesting to compare with roof-top solar:

Last season our single bee colony in suburban Melbourne produced:
  • 70 kg of honey (extracted for human consumption - total production probably ca. 250-300 kg);
  • 891,000 kJ;
  • 2440 kJ per day.
The hive has a foot-print of 0.16 square meters. Prior to extraction the hive (with one super) stored 20 kg of honey, or 255,000 kJ. Cost ca. $500. Value of honey produced ca. $1000, wax ca. $30.

A 6 kW roof top solar system (now the Australian standard) on our roof could produce:
  • 28,908,000 kJ/year
  • 79,200 kJ per day
The system would require 19 solar panels and would have a foot print of ca. 33 square meters. Tesla Power wall 2 could store 48,600 kJ. Cost ca. $7,500 + $9,600. Value of electricity produced ca. $960 (11 c/kWhr feed-in tariff), or ca. $1840 if replacing purchased electricity.

Not exactly comparing apples with apples (chemical vs electrical energy), but interesting...

So if you spent the same amount of money on hives, bees etc. as you would in a 6 kW roof top unit how do the results work out?
