Solar panels are best positioned due south [north in the southern hemisphere] perpendicular to the sun's spring and autumn midday equinox angles to give the best angle of incidence depending on latitude and need to be carefully set out to avoid any overshadowing from the top of one panel to the bottom of the next otherwise they are very inefficient, which leaves the rest of the ground unshaded and open to the sky. Also modern solar panels need not be opaque- the PV circuits can be printed on many surfaces including glass or polycarbonate so they allow 90%+ of the sunlight through + the rainwater can be channeled to either be collected and stored for a more even distribution during dry periods or just to drip off to soak into the ground if there's enough precipitation.

With screening to the south in the northern hemisphere and the north to the southern hemisphere protecting the crops from the prevailing winds the ground can heat up more evenly beneath the translucent panels so that crops can be planted earlier and harvested faster- great for vines!

Another great no-brainer use would be to put solar farms over south facing building elevations creating semi-enclosed atria and also to roof over supermarket and city car parks to generate 'free electricity' and give shade to cars reducing the need to waste energy powering up peoples' cars' air-con when they return
