Data from our solar panels for the months August through to November 2011. Click on the pdf link below for graphs.

But just in case you can’t be bothered downloading the file and having a look, here’s the most interesting graph:

You can see that as we head into the summer months we get a dramatic increase in energy generated compared to the winter months.

Here’s the update on our panels after the month of April.

During the past month we exported about 60% of March’s export, or 380 kWh. We generated 455.6 kWh, down from the month of March due to the approaching winter months. We used 75.5kWh of what was generated – less than last month- and imported 98.6 kWh which was also slightly less that our import during March.

On average, our daily generation was 15.19 kWh, our daily export 12.67 kWh, our daily use from the panels 2.52 kWh and daily import 3.29 kWh.

You can compare these daily averages with those from March, here.

Even if we are generating less electricity now, the rains are filling our 18,500L tank and the whole house and garden is running off of rain water now. As long as we get a decent rain every week or so we can continue to exclusively use rain water for the next 8 months or so until summer hits again. Currently, we think the tank is a little over half full. It makes for much nicer drinking water in the house.

On the first of March we had some solar panels installed on our house.


In total, over the month they have been installed, they have generated 610.2kWh. We have exported 508.2kWh of what was generated (83%), used 120kWh of pure solar energy as it was generated during the day and bought back from the grid 113.3kWh for use overnight when the panels have no sun.


Our average daily solar power generation was 19.7kWh (with a maximum of 28.97kWh and a minimum of about 5kWh on one very wet and cloudy day). Our average daily export was 16.4kWh, we used on average 3.9kWh of solar energy during the day and 3.65kWh imported from the grid overnight (average daily use 7.55kWh). Benno should probably write on his website that Transmog is a solar-run business.
