Since 08 October 10.00AM we are connected to the servers of SolarNRG. From there all solar panel installations are available to see your “green” profit by day/month/year. There is also a screen where your whole installation is displayed with the profit per panel, accumulating over the day:
This picture was taken 09 October 2018, 08:35AM. Just after sunrise. That is the reason that the day total (green, right upper corner) is still so low: 15W.
However, as the installation of the panels, the inside electric cable work and all the paperwork had finished after sunset (about 6.30PM), there were no results for this day. Then it took time to install our installation on the servers of SolarNRG in Germany. As from 8 October 2018 we can check the solar power installation on the computer, on the screen of the converter (pictures below) AND on a smartphone:
On the picture: the middle section Vdc represents the voltage that the panels give in a single current power; the left section Vac represents the voltage in alternating current, as we use in Western Europe. The right section represents the number of Watts produced that day (in this case: at 2.30PM 1,109kW). The P_OK indicates the number of panels that are functioning; in our case that should always be 10/10.
This picture is taken just before bedtime: only the alternate current number is used now. There is no input from the panels, so the production in Watt is zero.
Our house and the installation places of the panels (red cirkels).
On the flat roof: 5 panels.
On the slanted roof: 5 panels.
Gross: 10 solar panels, all costs included; € 4,814.98 / £ 4,300.22 / CA$ 7,427.00. Tax refund because the investment in Green energie: € 705.66 / £ 630.22 / CA$ 1,088.46. Nett costs installation: € 4,109.32 / £ 3,670.00 / CA$ 6,418.54.
This is the most efficient power position versus time: in wintertime at 10:50am GMT+1 (UTC+1). You can check that at the shadow of the chimney on Pierre’s sundeck. Next Saturday we change to summer savings time. Then this situation will be at 09:50am GMT+1 (UTC+2).
After discussions with the supplier/installer of the panels and also with the Dutch community for house owners (VEH), which has set up the activity, we have made a master plan for placing the panels. The installer can have an other opinion, as he does not work with the measurements, but with satellite images of the house.
However we plan the following:
On the flat part of the roof, over the nett width of the house (5.60m – 19ft) five vertical panels of each 1.0m width and 1.65m highth (3.3ft x 5.5ft).
Solar surface flat roof: 5.0m x 1.65m = 8.25 sqm (88.8 sqft)
The top roof construction on the right side is not very effective. On the left side of the window we have a usable top roof surface of 1.20m (4ft) width and 3.90m (13ft) highth. That implies two vertical panels, in total 1m width and 3.3m highth (3.3 ft x 11ft). Above the window there might be space for a horizontal panel, or the alternative one vertical panel on the right side of the window.
Solar surface top roof: 3.0m x 1.65m = 4.95 sqm (53.3 sqft)
