A solar energy system 1, for heating a body of water, comprises a solar radiation receiving unit 2 configured to receive solar radiation and configured to convert the solar radiation into heat energy or electrical energy. The system also comprises a barrier means 3, for varying the solar radiation transmittance, arranged over the solar radiation receiving unit. The barrier means is configured to varyingly control the solar radiation receivable by the solar radiation receiving unit. Preferably, the barrier means comprises electrochromic glass panes configured to transition or be switchable between a state in which the barrier means is substantially transparent and a state in which the barrier means is substantially opaque. In an aspect of the invention, a structure for containing a body of water, such as a swimming pool, comprises a solar energy system as described above. In a further aspect of the invention, a method of heating a body of water using a solar energy system is also disclosed. |
