Solar cloudy cutoff switch for storage heaters
What king of device could turn on the power
to an electric storage heater only when its sunny and my solar panels are exporting energy to the grid? [george] |

Assuming you're on FIT, this is extremely expensive because you will be losing 43p/unit that you put into your storage heaters, but it will only cost you low rate (no idea, 6p/unit ?) to run them at night on E7. I know that sounds stupid, but it's because of the frigged solar panel scheme - you are being paid much more for your solar energy than it's worth. You need to minimize your own energy consumption when the panels are generating, and try to use energy when they aren't. If you really want to heat the house using solar, you need to use solar water heating into a thermal store. That way you are making much more efficient use of the energy, because you aren't going through the phase to convert it to electricity, which is very inefficient in solar panels. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Yep. The FIT is even more barking mad than it seems at first sight then. Even more barking when you find out that if you don't have a fully metered system you are deemed to export 50% of what you generate and get the extra 3p/unit export rate for that 50%. So you can use all the PV electricity lighting halogen lamps in your back yard during the day and get paid the 43p/unit FiT for all those units *and* extra 3p/unit of 50%. -- Cheers Dave. |

[george] Now you have found the problem of having the inverter in the loft, you can't see what it's doing/generating on the display. I think on a day when the sun is so strong, you won't need your storage heaters anyway. May be you could find a PV switch (outdoor lighting sort of thing) that has sufficient adjustment range to be useful. Or maybe site it indoors where light levels are reduced? You would need a suitable relay to carry the load and reverse it's action. Then you have the problem of warming the heaters when there's no PV. The problem with trying to reduce your electricity bills with PV is that you have to be there to at PV max time (ie midday). We are there & save around 25% off our bill. |

If you are going to have dispersed micro-generation, something of the sort was neccessary. People have got used to the idea now. They are popping up all round me now. Where they came unstuck was they never realised that interest rates would fall so low & people would buy PV to protect themselves. At the moment PV is insignificant but when/if it becomes common, it will be neccessary for updated smart meters will control them from a central point (Smart grid) PV news here http://www.solarpowerportal.co.uk/ http://www.decc.gov.uk/assets/decc/S...city/et5_6.xls |

They are available now but not fitted a) 'cause they cost more b) would reduce the income from the PV c) they are optional for small systems. Who is going to fit something that is optional, costs more, and reduces the income? -- Cheers Dave. |

I constant red light comes up on the meter when power is going the "wrong way". It flashes when power is going the "right" way So, the sun is shining, the inverter shows 2 kW, and your red light is flashing. Have you enough spare power to run the washing machine? How much are you already using? Load the machine, turn it on, return to the meters and the red light has stopped flashing. Then what? Chris -- Chris J Dixon *Nottingham UK Have dancing shoes, will ceilidh. The important red light to watch is the one on the incoming mains electricity. When that starts to flash, the meter is recording. You are consuming mains power. When it is on constantly, you are exporting. The red light on the PV stays on at night and flashes by day. One watt hour per flash. |

This means that you can slip a monitor over the cable feeding only the main consumer unit. Otherwise you cannot tell if you are consuming or exporting until smart meters arrive. Not neccessary .

Only if you know both can you (or a box of electronics) decide if there is generation to spare. If you have to spend anything significant to achieve this, it is unlikely to be able to pay for itself. Well, it's simpler to know what it is generating & then he can switch in a similar sized load. Simpler, if you say so, but wrong. If you ignore what is already being consumed, you are rather missing the point. Chris -- Chris J Dixon Nottingham UK Have dancing shoes, will ceilidh. |
