The sun can be harnessed for power generation or heating water.
Solar Water Heating Installations NYC
Solar water heating (SWH) or solar hot water (SHW) systems are for heating water only, not power. Solar water heating systems are easy to understand, water is circulated through the solar collectors- as the water passes by the solar collectors- it gets blasted by sun, the water is heated up and put into a storage tank.
There are different types of solar water heating systems, direct, indirect, passive and active systems. Different types of solar collectors are available for warm, mild and cold winter environments. Each type such as; thermosiphon, drainback, indirect, and active systems with heat exchanger in storage tank are designed for all the different parts of the world they have to work. The least expensive systems are for small applications located in parts of the world with warm weather year round.
In NYC we can only use Active Systems, with pumps, and storage tanks with internal heat exchange coils. These systems are more expensive because they offer freeze protection, over heating protection, and large enough volumes of hot water for multifamily dwellings.
SWH systems are designed to large enough storage tanks to deliver hot water for most of the year. However, in dead of winter, or during an extended period of poor weather, a solar water heating system will not be able gain to deliver sufficient hot water. In this case a gas-fired high-efficiency water heater is normally used to provide efficient supplemental hot water for the storage tanks.

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics are the only systems used in NYC, which convert light into electric current using the photoelectric effect.
