For a 6k W system using thin-film, you would need 44 panels supplying 136W each.
The panels cost 2, so the total would be ,768.
Typically, this number falls around 900 k Wh each month, but it varies wildly from household to household. This number is a measurement of how sunny someplace is. Choosing one or the other has major consequences for the rest of the installation process, so we'll look at the differences between the two before we make any decisions about how to mount them.
On the West coast, this number is between six and seven hours; on the East coast, between four and five. Crystalline Crystalline modules are the big blue panels that usually come to mind when you think about solar power. A 40 year lifespan is more than you can ask of many home improvement projects, and gives you more than enough time to make your money back in savings. These cells require a somewhat elaborate racking system. For a 6k W system (fully power an average household), crystalline panels would cost about ,500: You would need 25 panels supplying 240W each. Thin-Film Thin-film comes on a roll of flexible material.
If there's too many obstacles to crystalline panels, you'll definitely want to consider thin-film instead.
Roof Mounting Roof mounts are especially great since they're aesthetically pleasing and don't take up any space in your actual yard.

Because you're still on the grid, you'll still have power on cloudy days. These are the parts of a grid-tie system, in order: 1.
Solar Modules (aka PV Panels) collect energy from the sun and turn it into direct current. Power Inverter turns the DC from the panels into AC that your appliances can use. PV Disconnect lets you cut off power so that you can work on the system without electrocuting yourself. Your home's breaker box is where the solar energy connects to your house. Net meter connects your house to the grid, measuring how much power you take from - or give to - the power grid at large.
You can buy panels, racking, inverters, and more at Solar Town.
As we continue through this article, we'll look at some of the products that are available and what each will cost.Although the thin-film panels are slightly more expensive, you don't have to buy expensive racking for them.
