Carrots grow quickly at first, sending down a tiny orange root that expands and develops more quickly toward the end of its growing period. As with all root crops, rapid, steady development produces the best results. Keep the row weed free with light shallow cultivation or heavy mulching.
If the same. amount of residential-scale PV systems (1,200 MW) were installed in 2019 as in 2014, they. would cost customers roughly $800 million more in NPV than a comparable purchase of utility-. scale systems, under conditions assumed for the Reference Case.
For example, the total average cost of an installed residential PV system under the California Solar Initiative is $8.70 per Watt (including installation, as of January 2011). That translates to about $34,800 for a four-kilowatt system, the average size of a residential installation.
