hi everone

can anyone tell me which is the best solar panel to use and whats the differance is between them.

im new to solar and wind power but am now looking to install some solar panels that will be tied into the grid with a connection for a wind turbine that can be removed when were not at the house for long periods of time.

has anyone here done there own grid tied system or do i need to get the pro's in, im reluctant to pay someone else to install it if i dont need to as the prices they charge for the work involved are too high.

If you want FIT, if it's still available, you will have to use a MCS registered installer, i.e. a pro. If you're connecting to the grid and you need Building Regs approval you will have to use a Part P registered electrician, i.e. a pro. The pro will probably have access to panels at a price that you can't get, although you could try Navitron.org.uk, who sell quality MSC approved panels at very good prices, and get a pro to install them. Navitron have a good explanation of the different types of panel on their website.

Re the wind turbine, you will have to have a very good site to get a wind turbine to function efficiently. If you're in an urban area or you've got trees around you forget it; it won't be worth it.

Mono crystalline PV modules are usually more efficient than poly crystalline, however this is less important than it seems.
In most cases efficiency is not that important because sunlight is free.

What matters more is how much electricity is produced by say £2000 invested in modules. Both technologies are fairly evenly matched in that respect.

If you are considering a grid tie PV installation, then you may wish to have the installers fit an extra module that is not connected to the grid tie installation. This may be utilised for battery charging and is a useful doom prep.
It will be far cheaper to buy an extra module and have it installed as part of the grid tie job, than buying and fixing separately.
