Solar Pool Panels the Heart of the Solar Pool Heater
Solar pool panels (also known as solar pool collectors) are the engines that warm up the swimming pool water, granting free warm water over most of the seasons (but not during the winter). Principle of OperationSolar pool panels are in the heart of the solar pool heaters. Like their cousins the solar thermal collectors they directly convert sunlight radiation to hot water using the greenhouse effect. ConstructionThe solar pool collector is usually not glazed to make possible a lower production cost and a lower price to the buyer. Black coated dense meander of black coated pipes in which the pool water is circulated to/from the pool is arranged over a rigid bottom surface and absorbs sun radiation in the visible light wavelengths. The water warm up and the heat is trapped inside the pipes. The cheaper panels use black plastic garden hose pipes, the more expensive and more durable panels use copper pipes coated in black SizingThe larger the volume of water in the pool, the more panel area is required. The area is dependent on the following: - Wind (wind vaporize the water and cools the water surface)
- Amount of sun (sun inclination and how many hours are available during the day)
- Does the pool have a solar cover?
- How early in the spring you want the season to start and how late in the autumn you want the season to end?
As a crude estimate, the panels area is 50% to 100% of the pool area. For example, 15’ by 30’ pool (4.5m by 9 m) will require 225-450 square feet panels. Standard panel sizes are 4’ by 8’, 4’ by 10’ and 4’ by 12’. In this example, if you buy 4’ by 8’ panels, you will need 7 to 14 panels. You can start with the lower number (450:32=7) and add more panels as necessary to achieve a longer season Shopping Panels and Solar Pool Heater Shop Specialty Pool Products for Swimming Pool Heating Options
