Hi all. Part of my farm is off grid so has no mains electric, to combat this i have a 7.1kva generator that is really handy. However i have been thinking that the shed roof could be put to work be putting in some photovoltaic cells. What else is involved what cost, infrastructure, power out put per meter square etc.
Any one got any on their roof any preferred suppliers etc. Cheers. Rhubarb and custard let fly with their secret weapon. |

Off grid is about 2 miles from main farm so not viable. One of the neighboring farms was rejected a turbine cause the yuppies surrounding have too much time and enough money to put up serious protest, you know rich nimby types who don't get that farms are just as much a working space as a factory in town . Solar may have been easier to sneak in but if it won give the power i need I'll stick to the genny and disturb the peace and quiet. Rhubarb and custard let fly with their secret weapon.

PV's good. if you have a large enough roof there are companies that will rent the space and use it for commercial gains.
if your off grid the problem is storage of the electricity. UPS batteries etc are avaliable but i would go for water power if you have a hill side near by |

If your idea is to install a stand alone Pv, you can run fron a light to a what ever you need, to me this is the real solar energy not the solar fields that it just a financial product.
The components PV panels Regulator (MPPT) Inverter / Charger Batteries you need to consider what equipment you want to run and time example: 4 low consumpsion lights for 2 hour 1 grinder 15 minutes an so on you will have to define if is a continous use or weekend based on that somebody will run the simulation of your system and define the number of panels and capacity of the batteries and the inverter to. In order to reduce the initial investment you can connect your actual generator to the PV and recharge the batteries when low radiation if you choose and inverter/charger One important consideration on the regulator choose one with MPPT, there are expensive but worth every penny. Batteries if is a long term instalation choose 2V batteries and depend of the demand 12 /24/ 48 VDC Think in modularity, i mean, choose equiopment that you do not have to remove for other in case that you upgrade the system, it is very common install something and when you what to go further you need to bin it. Hope this Help |
