<p>Solar energy traps in panel form are mounted on a combination of one pivoted support leg and two pivoted nd extensible support legs so that by cooperative adjustment of the lengths of the extensible legs the panel inclination can be varied. System allows the panel efficiency to be kept high by adjusting the panel inclination to suit daily and seasonal variations in energy incidence, pref. by programmed or automatic control of double-action hydraulically or electrically extensible supports.</p> |
