Which solar panel company?

... though I then discovered that as I've found before with other club discounts, the company itself was already running a better special offer, so the 10% was trumped by what was on offer to the general public.

Photonics is a good company and I don't think you will do better than them. There are of course many good companies about but photonics certainly seem to offer good back up for their products which is a consideration. You don't have to ' match ' your inverter to the panel size. I have a 135w panel on the roof and a 2000w Pure Sine Wave inverter. If you fit an inverter, it is a very good idea to be able to switch that inverter off completely as an inverter draws current even when idling. How many batteries do you have? Just the one? You certainly won't be able to run any serious electric gear on that. Certainly not an Oil filled rad!!  I have to mention, as you are looking to go off grid, LPG. Although I am an absolute evangelist where self fill cylinders are concerned, simply because of the cost benefits, it's important that the heating of water, space heating and the fridge is handed over to the gas cylinder which you seem to have covered. If you decide eventually on a Solar Panel, and I think you will wonder why you didn't do it before, don't forget you will need a controller if over a certain wattage. There are certain advantages to each system- fitted to the roof you don't have to worry about theft or moving the panel around every hour or so but you do have to have a panel big enough to be able to produce power in less favourable times like when the sun is low in the sky. With a mobile panel, you have covered one- theft. Two you have to move it around to face the sun every now and again but you can probably get away with a less powerful panel than the roof one. I have always said for off grid caravanning that 120w would be my starting point but you know what you need better than anyone so I wish you the very best. Monocrystaline tend to be more productive ones. I am just over the Leicestershire border Hedge so if you would like to see an installed system let me know. biomerv@gmail.com
