pigpigoink Posted February 2 Share Posted February 2 first time see solar panel in this position. moi ish not sexpert but this shouldnt be the way to house it? the efficiency will be very low moi guess. just sharing. 2 1 Link to comment Share on other sites More sharing options...
Satki Posted February 2 Share Posted February 2 as in it is not angled towards the sun? Maybe we are in the tropics so the sun is more above us? 2 Link to comment Share on other sites More sharing options...

High efficiency and electricity production no use if they are only using it to charge lower capacity batteries to provide lighting for the HDB open spaces .. If they use HDB rooftops and side cladding to put the panels and pump back to grid, then got use 3 Link to comment Share on other sites More sharing options...

Satki Posted February 3 Share Posted February 3 so if morning sun, then afternoon it goes to sleep? no maintenance it will crash down 3 Link to comment Share on other sites More sharing options...
The_King Posted February 3 Share Posted February 3 The most important is the mid morning to afternoon Sunlight as it the strong In sg hit KPI can liao. Work or not. Dont care 2 Link to comment Share on other sites More sharing options...

It is okay if strike at angle also. But generate at full efficiency all through the day got no use - cos they are probably using it to power smaller batteries in teh HDBs or nearby to power the void decks, passageways and outdoor lighting only. That won't take long to charge - like full sunny day 2-3 will charge finish the batteries. On cloudy day maybe take 8-10 hrs to charge - but then on cloudy day, you have it facing East/West/South/North doesn't matter - as long as not facing the earth can liao 2 1 Link to comment Share on other sites More sharing options...

She should be a good housewife Actually got use la .. lower electricity usage a bit, and power gen companies prolly get free $$ for green energy. That said, if my house facing West or South, I'd be happy if this was sitting outside my apartment walls - will keep the home cooler cos of the shade and save on AC costs And hopefully won't have pigeons staying behind it and pooping 2 Link to comment Share on other sites More sharing options...

Just like the simply go. Which is a downgrade. Cause upgrade mean add ( enhanced feature, downgrade mean remove So I guessing it the same with the solar panel, spend as little as they can, make sure it look high tech is enough 2 1 Link to comment Share on other sites More sharing options...
