| Dear Martine, as I understand the installation process they lift some tiles/slates and screw metal brackets into the joists to which the panels are attached, and replace the tiles/slates. Here is a link to an explanation and video: https://www.which.co.uk/reviews/solar-panels/article/solar-panels/solar-panel-installation-aiRvu3N6OyEN#video-guide-solar-pv-installation. A panel weighs around 50 kilos. In my own case I use gas for hot water and central heating and consume 12,064 kWh, while my electricity usage is 2,860 kWh. My electricity bill is higher than my gas. It seems because of the limitations on how many panels can be fitted, the amount of solar electricity that could be generated would be around 2,000 kWh although this would vary depending on the amount of sunshine. Sometimes it would be enough to power all appliances, sometimes not. The shortfall would be made up from the national grid, at an off-peak rate. This is where a battery is essential, although they are pricey at £4,000 +. I presume that any outage from the grid would be covered by having the battery bridge the gap. I’ve now discovered that if you sell excess energy to the grid, which in my own case will probably be minimal, I will receive only 3.5p per KWh while if I buy from the grid the rate is currently 29.5p or higher! So much for the government encouraging us! Hopefully when we have a sane government they will increase the export tariff and introduce some grants against installation. Finally, there are of course many other factors to take into account: the saving of CO2 generation, the likelihood that gas and electricity prices will go on rising (the next rise in the price cap is expected in October). The state of my roof. Whether the installation cost makes sense balanced against the amount of money saved. Then of course there is the question as to whether I should substitute electricity for hot water heating rather than gas. Probably not, but I will see. I’m still waiting for a third quotation from another SPV supplier - I’m learning as I go along. Fortunately I have a fixed price energy deal for gas and electricity until June 2023, so I have some time to consider my options. Hope this helps. Nick |
