One major drawback of thin-film, however, is durability - Thin-film usually only lasts around 25 years.
The National Renewable Energy Laboratory has an excellent insolation map. Though crystalline modules are more popular, thin-film is gaining a strong foothold in the market due to its ease of use.
The two biggest advantages of thin-film are cost and convenience, since installation is as simple as slapping the module onto a smooth surface.
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 $16,500: You would need 25 panels supplying 240W each. Thin-Film Thin-film comes on a roll of flexible material.
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.Government financial incentives are still ripe for the picking, the cost of photovoltaic (PV) cells is falling every day, and you'll probably be the first person on your block to make the jump.Adding solar energy to your house is an excellent project for several reasons: You'll save loads on electricity, and may even be able to sell some of yours back to the utility company; you'll reduce your carbon footprint; and if you're installing in a remote location (such as a cabin), you'll have much less to worry about than you would with a gasoline generator.We'll review the parts of a solar panel system, the things you need to consider when you're planning, and how you can save money on (and even get free money for) your project.At the end of the day, you'll know what to look for and what to keep in mind with any solar project. If you've been thinking about going solar, there's no better time than now to do it.You can buy panels, racking, inverters, and more at Solar Town.
