Actually solar panels can be connected in parallel but it can get expensive to maximize the output. As I understand it if the units are parallel then there may be a problem since not all panels will put out the same exact voltageSuppose one unit produces 45V (DC) and another only 40V due to shading or whatever. The 40V unit would virtually be ignored so it would limit its ability however if each array had its own inverter than it would maximize the current. This, of course, would be very expensive.conarb said:I'm sure there is good reason but why can't they connect them in parallel instead of series?
Yes it is hard to work with these contractors.. Even I worked with one contractor for 6 months and those were horrible days of my lifeICE said:Solar contractors can be difficult to work with. The company will have a C-10 or B license so they will install a new service along with the solar equipment. I wish that they wouldn't.
That is the usual case. However, the fire dept allows different strokes for different folks. As long as there are two open sides, the fire dept. seems to go along with it. The 3' around the edges bothers me, especially on a second story. Sometimes it is mostly overhang and 3' with a 25' drop is not the best situation.McShan said:Aren't the panels supposed to be 18 inches away from the valley?
Is there a code reference for this? We're just starting to see PV panels around here, and we are trying our best to get up to speed on all requirements.McShan said:Aren't the panels supposed to be 18 inches away from the valley?
