With the main focus on reducing the energy spent on my remote observatory, I added two solar panels.
It’s a very simple installation with two 405W Deep Blue 3.0 JA Solar Mono panels and a microinverter.
This Deep Blue panel is a mono crystalline half cut PERC cell panel that uses the latest generation technology available. It’s not a big panel, only 170cm x 110cm (about 2 sq meters).
And of course a dual-module microinverter from APsystem, model DS3 capable of generate 880w in order to simplify the installation to the minimum.
All elements are located on top of the roof, only a 230v cable goes inside the observatory connected to the distribution board.
This roof has only a 16º of inclination, not enough to set the panels properly to my latitude but after one week running, I am happy with the performance results.
We started this project in spring, on my latitude the sun it’s at 45º at its culmination these days, 16º of inclination is not the best angle but I saw more than 500w generated during a few hours daily, really impressive.
We will see how it performs in summer time… and what happens next winter.
Also I collect all data from this microinverter using a ECU-b unit to provide all the statistics and incorporate all info on the allsky camera.
