I remember there was a HG member that was a PV tech. I wanted to ask a few questions but I cannot find the thread.

I am interested in getting a grid tied system but no nothing about them.

I heard China is dumping right now and the price of PV systems has dropped a lot. I was wondering what are the better PV panels and inverters and if I should bother installing a solar water heater later, or first, or at all. (We use a lot of hot water).

If a pro member can point me to the old form I'd appreciate it.

I put up a couple of solar water heaters so I know what to expect from them. I would love both a solar water heater and a PV system but I don't really have the cash for both right now.

Also have any of you heard about battery tech that will make off the grid/ or at least battery back up systems feasible? I heard China was also driving the prices of Lithium ion batteries for houses down. I like the idea of not havin to check the water all the time.

Yeah I wish I could buy panels made in the USA but damn panels used to be so damn expensive, like 50-60K.
