How do you design a solar water pumping system?

When designing a solar pumping system, the designer must match the individual components together. A solar water pumping system consists of three major components: the solar array, pump controller and electric water pump (motor and pump) as shown in Figure 1.

How many solar panels should a water pump have?

Setting the solar panel power to 1.5 times the power of the water pump is a theoretical value. It can be adjusted based on local sunlight conditions. If sunlight conditions are good, you can reduce the number of solar panels. Conversely you may need to increase the number of solar panels to ensure an adequate energy supply.

How to design a solar PV system?

The simplest type of PV system one could ever design is by connecting single or multiple PV modules directly to the DC load as shown in figure 1 below. The overall capacity of the modules is such that it can supply power only during the sunshine hours.

Where is a solar hot water tank located?

The storage tank, and the heat exchanger contained within it, are the largest part of a solar hot water system and are usually located in a basement or utility closet, where they are accessible by water lines and antifreeze tubing. If you are replacing a gas-powered water tank, this step is essentially a replacement project.

What size water pipe should a solar water pumping system use?

The designer should initially use pipe that is the same size as the inlets and outlets. The designer then undertakes the frictional loss calculations for that size of water pipes using the known maximum water flow for that solar water pumping system.

Can a different water source change the design of a solar water system?

The water source used in the construction of the water system must be the source used in the design of the system. Use of a different water source would change the design of the solar powered water system.
