8. The control room where batteries are placed should be well ventilated. Components like
the power conditioning equipment can be installed in the same room or in a separate room
adjacent to the battery bank.
9. To minimize wiring losses, all the PV components should be placed close to each other and as
close as possible to the modules.
In addition to solar photovoltaic, there are few other renewable energy technologies that can be used
for generating power on site in order to meet some portion of the building’s energy requirement.
Small-scale wind turbines
Use of turbines for generating power from wind is one of the fastest growing renewable energy
technologies worldwide. Large- and medium-scale wind turbines are economically more feasible as
compared to small-scale wind turbines. However, growing interest of people to generate pollution-
free electricity has created a market for small-scale wind turbines and encourage the manufacturer
of such turbines.
Power generated by a wind turbine is directly proportional to cube of the wind speed. In urban
and suburban areas where wind turbines are installed near buildings, factors like height of the
turbine and obstructions (trees near the buildings) may slow down wind speed. Therefore, in such
Figure 4 Wind turbines
cases, factors such as annual average wind speed of the area and location of any major obstructions
nearby should be considered before deciding to install a small-scale wind turbine for meeting a
building’s energy demands.
