CPVC pipe has been used since working with CPVC is easier than Copper pipe. Also the CPVC efficiency is closed to Copper efficiency; it is only 4% or 5% less than Copper. To compensate for this, we can make larger Collector or increasing the number of Collectors.
Frame and Base:
Putting insulating foam with aluminum sheet on the base and the insides of the frame to reduce heat loss.
The base has been painted. It is not necessary.
Cutting the pipes to fit inside the frame.
Collector after gluing the CPVC parts together:
Collector after being painted. The metallic strips will be used to hold the glass on the top of the Collector:
Collector Work has been completed. The water inlet is located on the left. The water outlet is on the lower right and the sensor connection is on the upper right.
Updated Differential Controller: Digital temperature sensors are being used instead of analog sensor for more accuracy and using only one digital input for multiple sensors.
Water proved Box is used to protect the electronic boards and also give nice looking to the Controller.
Digital Sensors with 1/2 inch adapter. The adapted does not come with the sensor. It was bought from Home Depot and was modified to fit the sensor.
Solar Panel to feed the electronic boards.
The batteries will be charged from the solar panel via the charge controller to keep the electronic boards on during the night.
The 12V DC water pump will circulate the water from the collector to the water tank.
