[QUOTE="Joules, post: 536157, member: 35656"] Solar radiation is called ‘Insolation’ and its unit of measure is in Watts per square metre or W/m2. Solar panel ratings are set at an insolation value of 1000 W/m2 and efficiency is the based on the area of the panel exposed to sunlight not the dimensions of the panel itself. Physics dictate the efficiency of generation and the theoretical limit is around 30% the best achievable in the market place is around 22%. You can purchase insolation meters to measure the strength of sunlight at any given moment. Advice: don’t do an install yourself rather use an accredited installer or if you must do it yourself first obtain DNO approval in order to obtain SEG payments through a smart meter. As for self-consumption your GTI allows this under appropriate foreign regulations, for example the Philippines however UK G98 regulation do not accommodate zero-export and the GTI manufacturer will not tell or help you setup or wire the inverter for self-consumption zero-export in the UK. As for funding your install, many will talk about pay back especially if SEG is involved. You can get around the lack of pay back by saying the cost of install is a lifestyle change no different to that of changing your car.
