[QUOTE="binky, post: 459290, member: 490"] a 4 kw array will generate around 4000kWh per year and around 15-30 kWh per day for about half the year (weather dependent of course). A recent 4kW array I fitted just before xmas is doing about 10kWh per day currently, when the sun is out. Depending on your roof spave and connections to the national grid a slightly larger split array might work better for you given the steady base load that you have. You could also fit a Solic 200 to divert surplus energy to your water heater, assuming it has a storage tank. Expect to pay around £6-7k for the 4kW system, using all German parts. I normally fit Q-Cell panels and SMA inverters. If you need to build a ground array, a simple wooden frame that you can build yourself is cheaper than off the shelf frames. you can have a look at other peoples systems here [URL="https://www.sunnyportal.com/templates/publicpagesplantlist.aspx"]https://www.sunnyportal.com/templates/publicpagesplantlist.aspx[/URL] [/QUOTE]
