Among the first questions that individuals that are contemplating installing solar panels will ask is, “do the panels need to be sited on a rooftop?” The answer to this question is, no – not necessarily. However, the roof of your house is usually the most convenient place to put them.
To get optimal performance from the solar panels you will need to site them onto a south facing rooftop free of any color or obstructions, and in an angle of thirty degrees. In addition, you need to be certain that there are no overhanging tree branches because the droppings of birds and other creatures such as squirrels can cause very serious harm to the translucent cover surfaces.

As the point of your project is to supply hot water, and because most hot water tanks are located in a loft area, installing them on the roof-top means the heated water is going to have the shortest possible distance to travel to get into the holding tank. And there’s another plus you may need much less insulation on the water pipes.
But what if your house has a flat roof instead of an angled one that you might ask? The solution is, not an issue. All you will need to do if you just have a flat roof is build a frame at an angle of 30 degrees, making certain it’s facing south. Then simply mount your panel home on the frame. However, you’ll have to insulate the bottom of the panel casing to be able to maintain the warmth.
Solar panels have few working parts which are vulnerable to failure, however, they will require some maintenance from time to time including cleaning off the translucent cover. So this is a point worth taking into account when deciding where you will site the units.
There are two major types of solar panels. The first is the right flat panels that were designed just to give hot water and the next sort of unit that contains photo-voltaic cells which may actually provide all the electric power necessary to run your dwelling.
