The First Kilowatthour

Solar panels where installed earlier this week and despite grey November weather, today the first kWh is produced, meaning the energy required to pull a standard car up the Eiffel tower.

The panels should generate 1.5 times the electricity required on a yearly basis, for a relatively modest standard consumption pattern to power desktop computer + monitor, fridge, freezer and television. The converter has a build-in wifi and can send the solar production data via the internet router to a server. Via a browser actual and cumulative data can be displayed, see screenshot above.

Additionally, the smart meter bridging the household with the grid operator also has a wifi, enabling to read consumption data, see iPhone-6 screen shot below.

In other words, at 11 o’clock on a half-clouded morning in November, the panels already produce more than is consumed. The rest is fed into the grid.

Later this month a gardening center will deliver a few m3 compost to upgrade the soil of the garden, that next season will be fully utilized for food production.

Next prepping investment will be focused on producing ‘hot air’. The idea is to install 8 or so 100*165 cm solar panels (for electricity) against a palisade and additionally put glass plates in front of them, leaving a space of 5-10 cm. The panels are black and hence absorb all radiation. 10-15% will be converted into electricity, the rest into hot air that can be pumped into the living room with simple desktop computer ventilator.

*** UPDATE ***

After 13:00 MET the sun began to shine, 2.15 kwh on one November day with only two hours of sunshine.
