How will this affect the performance of the proposed solar water heaters (If you live in an apartment with a flat roof I guess you'll have to pretend that you live on the top floor!) Would there be any practical limitations to the installation of a SWH system. On the roof, the best part would be dependent on two factors: first, it has to be near or at the center part of the roof so that more amount of sunlight falls on the SWH for a longer period of time (from dawn to dusk). Second, it has to be at a requisite to keep it out of reach from children. The limitations in any case would be the amount of open space that can be found on the roof and whether that open space is well lit by sunlight for most part of the day. Also the cost of maintaining and... ) Would there be any practical limitations to the installation of a SWH system. On the roof, the best part would be dependent on two factors: first, it has to be near or at the center part of the roof so that more amount of sunlight falls on the SWH for a longer period of time (from dawn to dusk). Second, it has to be at a requisite to keep it out of reach from children. The limitations in any case would be the amount of open space that can be found on the roof and whether that open space is well lit by sunlight for most part of the day. Also the cost of maintaining and the safety measures adopted play a critical role in the successful and efficient role of the SWH system. 3. Using your own house as an example estimate how much hot water your family consumes each year. (As a rough estimate determine how many showers, baths, and basins of hot water are used per week and make a pro-rata calculation for the annual hot water consumption. Remember that most hot water used would be mixed with the cold water. It's not important to be 100% accurate but this will give you an idea of the magnitude of the hot water usage. Average European hot water usage is currently in the range of 15-35 liters of hot water per person per day depending on if you shower or bath!) 4.
