Photovoltaic | How Much Would It Cost To Setup A 1 Kilowatt Photovoltaic System?

How much would it cost to setup a 1 kilowatt photovoltaic system?

200W panel = $1000 x 5 = $5000plus mountingplus a 1 kw inverterplus DC wiring (lots of copper)plus electrical safety disconnectsProbably $7500 -$10000 or so…before gov’t subsidiesThe link below has a pretty good calculator and came up with about $9500 for a 1 kw system (might be a bit high…)

The biggest determinant would be how much, if any, rebate you get.

Suppose you live in California. If you shop carefully, you can find panels for $4.50 a watt. So that’s $4500 worth of panels. Also, assume you are doing a grid-tied, no battery system. Add $2000 for an inverter, and by the time you get all the other parts, it will be about $7500. From the federal government, you will get a 30% tax credit, capped at $2000. So you’re down to $5500. In California, the state rebate is about $2/watt. A little more for Southern California, a little less for Northern, and it declines with time. That means another $2000 back, roughly, knocking the cost down to $3500. That assumes you install it yourself, which I THINK is still possible (link below for an example). If you have an installer do it for you, add maybe $3000 to that.


Different states, different countries, different costs and rebates.
