Solar Panels
Solar Panels use a mix of different types of silicone type p (positive) and type n (negative) to generate power when hit with photon's from sunlight.
Installing
Fire Proof Board
Clearance around Inverter
Clearance around Inverter
Inverters must be mounted on a fireproof backing board unless already on a fireproof surface.
Clearance around Inverter
Clearance around Inverter
Clearance around Inverter
Check installation manual for clearance around inverters and batteries, it varies between different inverters.
Cable Safety
Warning labels
Warning labels
Keep solar cables and connections clear from the roof, cable tie or conduit.
Warning labels
Warning labels
Warning labels
Remember all warning labels, every 5m for DC cables and on bends. Label at main electric meter box and consumer unit indicating dual supply.
Testing
Inverter serial number
Battery serial number
Solar Panel model number
Mounting type (Roof/Box/Frame)
Total rated solar power (times the power of one panel by the amount of panels you have)
Location of Panels
Estimated system performance (ask James if it's not on tradify
Voc (STC) - open circuit Voltage (standard test conditions)
This is the expected voltage of your string of panels, you'll have to find the Voc of a panel and times it by the amount of panels you have (James should have this information if it's not on tradify)
Isc (STC) - short circuit Current (standard test conditions)
This is the expected Current of your string of panels, you don't have to times this by the number of panels the Isc for the panel will be the same as the string.
These are the results you get from testing, they should be similar to the array parameters, the Isc may vary quite a bit depending on on the weather (lower on cloudy days or higher on very hot days)
