As there are different types of solar panels available, it is important to be familiar with the differences so that you can be sure that you are getting the right solar panel for you. Just remember that it is a good idea to have a qualified installer carry out the actual work as good electrical knowledge is required.
Standard solar panels are easily recognisable as they are appearing on more and more roofs across the country. These are positioned so that they can pick up the maximum amount of daylight and sunlight and they are fitted in place using an aluminium bracket.
Solar tiles could be an alternative to the standard solar panel if you want something that blends in a little better with the roof. The tiles can be locked together and can be slotted onto the roof in place of some of the roof tiles. However, you need to be aware that they are more expensive than the standard solar panels and they do not have the same efficiency levels.
Another option is the thin film solar panels. These are very light although they will require more space than the standard solar panels because their efficiency is not as high. In addition they may contain something called cadmium telluride. This has been categorised as a toxic substance and when the panels come to the end of their life the disposal needs to be planned carefully.
You should consider whether or not you want a tempered solar panel. The surface of this panel is strengthened glass, which is considered to be better than plate glass because it gives the panel a longer life. This can cost more to begin with but as the panel will be in place for much longer than a plate glass panel there are better long-term savings.
