Obviously the performance of a solar thermal system will vary depending on the location of the home, the insulation of the property, and your own hot water requirements. Solar thermal panels are capable of providing all of your hot water requirements from April to September. They will still make a contribution to your hot water needs for the rest of the year, but in general you will need a backup system to further heat the water in the colder months.
Cambridge
Cambridge isn't an especially big city yet takes centre stage due to its top university, that it's iconic for. The city itself just has a populace of 125,000 yet pulls in a lot of tourism with the river interest and other activities. There's a variety of housing inside the city as well with older and modern properties, so whether it's insulation or renewable technology, make sure you keep your Cambridge house up-to-date.
