5 Factors to Choose the Right Collector for Solar Water Heaters
Solar energy comes to earth through electromagnetic radiation, i.e., infrared, visible, and ultraviolet light. A solar collector or solar thermal collector is a device that collects heat by absorbing solar radiation. It's a significant device in a solar water heating system. Indeed, there are two main types of solar collectors, i.e., flat plate and solar evacuated tube collectors . Read on the below-discussed factors and make a well-informed selection for your solar water heating system. 1. Cost Cost is essential when choosing a solar collector for a solar water heating system . The advantage goes to the flat plate collectors. Usually, solar evacuated tubes cost 20%-40% more than flat plate collectors. But you can get maximum return from your investment in solar evacuated tube collectors within a few years, making them a cost-effective investment for solar water heating systems. 2. Efficiency There is no heat loss through convection and conduction in evacuated tube col...
