There are numerous issues with this.
To name a few... The output of a panel is related to something like the cosine of the angle of incidence. As the sun moves the output changes. You can keep the angle perpendicular with a two-axis sun tracker. If you try to use mirrors, how are you gonna arrange them? How are you gonna track the sun? A small change in incident angle decreases solar output by a small amount. But a change in the angle incident on the mirror can cause the energy to miss the panel entirely. Even a partial miss can decrease output dramatically. Then there's heat. If you've ever tried to start a fire with a magnifying glass, you have seen the effects of concentration. Somebody has to keep the mirrors clean. Mirrors work great when you have a bunch of them actively tracking and projecting/focusing the energy on a small boiler high in the air. |
