4 August: After our meetings with suppliers, and some extremely interesting conversations, we will be adding these clauses to each of our reports. If you have already had one of our report, please note the clauses carefully. We will add these to our 'Frequently Asked Questions' pages.
Roof thoughts: If your roof is very old and fragile, and if you do not have underfelt, or you suspect rot in the timbers, undersized rafters, flaking tiles, slipping slates, chimneys about to shed pots or bricks, ridge or hiptiles about to fly..... do not continue. The panels last over 25 years and if your roof needs a significant refurbishment or felting sooner than 25 yrs it would be expensive to take all off, add felt, retile and refix panels - do it now, then put the panels on after. On the positive side, a mesh of strong alloy rails attached to your roof will make it stiffer, and the rainscreen effect of the panels will protect your roof against future weathering - but the roof must be sound in the first place.
Insurance thoughts: The panels become fully part of your house and your insurer will usually add these freely in when you your system is fully commissioned - but if you haven't told them, they wouldnt know, and you would not be covered - so phone them.
Reflections on energy conservation: If you already have a very high energy consumption, do not forget that there are cheaper ways to cut your bills than to spend several thousand on a Photovoltaic roof. Do an energy audit on your house and lifestyle......
- improve insulation
- see if windows are adequate
- instal energy efficient light bulbs
- turn off standby devices at night
- reduce your thermostat by a couple of degrees
- have more showers than baths
- turn off external spotlights, garden lights
- adjust your central heating programmer to turn off earlier in the evening and later in the morning....
- ......and many more such ideas, some of which cost nothing.
- Keep all your energy bills, and look at them going back for the last two years, calculating both your energy consumption per year for electricity and gas, and setting savings targets for next year. If you make some energy improvements to the house, note your energy bills for the next quarter and compare them with the same quarter the previous two years.
The
Energy Savings Trust website has a very comprehensive list of ideas.
