 Power of Renewable Energy for Your Business

Introduction

Commercial solar water heaters offer a sustainable and cost-effective solution for businesses seeking to reduce their energy consumption and environmental footprint. In this article, we'll delve into the workings of commercial solar water heaters, exploring their benefits, components, and installation process.

What are Commercial Solar Water Heaters?

Commercial solar water heaters utilize solar energy to heat water for various applications, such as space heating, domestic hot water, and industrial processes. These systems consist of:

- Solar thermal collectors (flat plate or evacuated tube)

- Heat exchangers

- Storage tanks

- Pumps and controls

How Do Commercial Solar Water Heaters Work?

The process involves:

1. Solar radiation absorption by thermal collectors

2. Heat transfer to a fluid (water or glycol)

3. Fluid circulation through a heat exchanger

4. Water heating and storage
