Harnessing power from the sun is all the hype these days. With the Renewable Heat Incentive that is being introduced 2011, it will prove to be quite cost effective after the initial installation fees are paid up). Another advantage is that you will be going green as it is environmentally friendly, but do solar thermal panels produce hot water in the winter?
This system should account for about 60%-70% of the need in a home throughout the year. It will however generate considerably more in the summer than in the colder months. You can make it go further in winter by taking a shower instead of a bath and by washing your clothes at a lower temperature.
This system cannot yet replace your general system, but it does work alongside it. The traditional boiler will top up your tank when the solar production of hot water decreases in the cold months.
There are 2 types of thermal systems; called passive and active systems. Both include a general heating system like gas or an electric element that will kick in once the tank falls below a minimum temperature.
Throughout most of the UK this system will work best when installed on a south facing roof, as it will get the most sunlight through the day. Although, installing a panel on each side if you have an east and west facing roof, would also make it effective. Installing panels on a north facing roof might not be worth the money.
There are many benefits to having this system installed at your home, not only for environmental reasons, but also financial reasons. So, do solar thermal panels produce hot water in the winter? Yes, they do. It is just less than what they would make in the summer, but then your general system will make up for the rest.
