This invention provides a better means to achieve affordable solar energy. It does so by increasing the efficiency and capacity of control grids (for addressing and alignment) in solar concentrators, and similar equipment. Method and apparatus are described for going from a 25% grid efficiency and capacity to a more than 90% grid efficiency and capacity. The instant invention relates to improvements in the control (addressing and alignment) grid for Solar Energy Concentrators, and similar equipment. The control grid acts to address and align active optical elements such as mirrored balls, electrophoretic, and magnetophoretic cells in solar concentrators [e.g. cf. U.S. Pat. Nos. 7,133,183 and 6,843,573 by M. Rabinowitz]. This invention also reduces the cost of transistor grids by greatly reducing the number of grid junctions and hence the number and cost of transistors. Moreover, the present invention simplifies the grid making it more feasible to use the same voltage supply sequentially to further reduce costs, rather than having multiple voltage sources.
