1. A solar energy collector system comprising: an elevated linear receiver extending generally in an east-west direction;a polar reflector field located on the polar side of the receiver; andan equatorial reflector field located on the equatorial side of the receiver;wherein each reflector field comprises reflectors positioned in one or more parallel side-by-side rows which extend generally in the east-west direction, the reflectors in each field are arranged to reflect incident solar radiation to the receiver during diurnal east-west motion of the sun and pivotally driven to maintain reflection of the incident solar radiation to the receiver during cyclic diurnal north-south motion of the sun, and the polar reflector field comprises more reflector rows than the equatorial reflector field. 2. The solar energy collector system of claim 1, wherein the receiver comprises a photovoltaic device which absorbs solar radiation reflected to it by the reflectors and converts the solar radiation to electricity. 3. The solar energy collector system of claim 1, wherein the receiver comprises an absorber that absorbs solar radiation reflected to it by the reflectors to heat a working or heat exchange fluid. 4. The solar energy collector system of claim 1, wherein reflector rows on opposite sides of the receiver are spaced asymmetrically. 5. The solar energy collector system of claim 4, wherein the receiver comprises an absorber that absorbs solar radiation reflected to it by the reflectors to heat a working or heat exchange fluid. 6. The solar energy collector system of claim 5, wherein the receiver is tilted in the direction of the polar reflector field. 7. The solar energy collector system of claim 5, wherein one or more outer rows of the equatorial reflector field have focal lengths greater than their respective distances to a solar radiation absorber in the receiver. 8. The solar energy collector system of claim 5, wherein the receiver comprises a window through which solar radiation reflected by the reflectors is directed to the absorber and the window comprises an anti-reflection coating having a maximum transmission of solar radiation at an angle of incidence that maximizes an annualized solar radiation collection efficiency of the solar energy collector system.
