How will bi-facial solar panels "potentially" change roof design?
Posted: Thu Dec 09, 2021 10:51 am
I was looking at the "partial shading" & reflective energy return claimed.
Construction "appears" to be a dual sandwich of tempered glass making it tougher & more akin to a roof tile than ever before.
Therefore, how will home design / estate design, utilising natural light change?
How will loft areas change in design (ie will they become insulated, covered over with reflective foil to maximise bounce back energy with covered ducting for utilities beneath) >
Solar porches, covered edge shading, gazebo's, walkways etc?
The idea of putting a small ASHP under bi-facials & a white / light coloured ground covering & having 800w -1200w through to 2 kWh potential variable solar output benefitting an ashp could use is obviously appealing from a self sustaining / seasonal offsetting potential. (for small read 2 or more LG panels at 415 watts basic power as tech currently stands v panel size)
Could we for instance strip back a low ground floor roof, insulate it (PIR foil), then box out sections as needed with a highly reflective material foil insulator for the absorbency, or would we be approaching solar cooker territory & added complexities of fresh air circulation etc ?
My thoughts are that if you can grow a delicate fruit like the strawberry under these panels then there are minimal under glass magnified hot-spots & therefore a more even heat distribution so skin fries less & the covered outdoors has more appealing use & sense of airiness & seasonal room use to cramped new estate design dwellers
"yeah but transparent roofing"
I'm waiting for Desp's input especially on this one in terms of uk roofing truss stocks suitability
