    Using solar panel DC output to feed immersion heater?

    Just an idle thought - has anyone any experience of using the DC output of solar panels to directly feed an immersion heater, to avoid the expense and losses associated with an inverter?

    Will replacement panels of same total capacity jeopardise FiT payments

    Hi all, as per the above title. If one is to replace the existing solar pv panels for a new system of equal capacity (existing system is 8 x 250w=2000w total) with 5 x 400w=2000w in total, will that risk jeopardising FiT payments. By doing that it would give enough room to add 4 more panels of...
