I had my Solar panels fitted in December 2014 and have waited until now to review so that I knew how effective they were over the year. The installation was very efficient, Craig and Brian worked really hard and finished the install in one day, they were extremely friendly and polite and left everywhere clean and tidy. I didn't see much difference over the winter months as it was very dull weather, but was pleasantly surprised to get a cheque for £69 from British Gas for my feed in Tariff after three months. My monthly Direct debit to my electricity supplier has been reduced and the second cheque arrived in August for £237!!! I am extremely pleased that I purchased the solar panels - after much agonising. I have just one problem:Whilst the I boost is brilliant in that it heats my water during the day, on a dull Summer day, I have to light a fire to get hot water, as my immersion heater doesn't work independantly.
