With a correctly designed PV system you can power almost any
electrical load. However, as the load size increases the expense
also increases. Loads like hot water heaters, air conditioners,
room heaters and electric stoves should be avoided. The added
cost of trying to power loads like these is very cost prohibitive.
If these loads have to be powered it will be a lot less expensive
to change the appliance to use an alternative fuel type like
propane.
