Will my house be suitable for a solar system? 

Not all houses are set up for solar as well as others. There are many offerings now that allow for panels to be mounting in all sorts of manners and in all sorts of angles and pitches. Also shading is now less of an issue with the ability to install power optimisers or micro inverters to avoid a lot of the losses that would occur. A qualifies installed will talk you through your options and whether solar will work unfortunately some instances will not be conducive for solar but most houses should be quite acceptable for a solar energy system.
