How to Ensure the Best Investment in Solar Evacuated Tube Systems

April 23, 2018 - No Responses

The solar evacuated tube collectors are designed with individual round tubes to capture and convert the maximum amount of sun rays into heat energy for the solar heating system.  They are also perfect for a variety of applications such as solar hot water heating, solar space heating or solar pool heating in ice-cold climates. The solar evacuated tubes function in a closed loop, open loop, and drain back solar systems, efficiently even at a temperature as low as -40 degrees C when flat plate collectors may fail to perform. Additionally, there is little chance for weight or roof structural issues with the solar vacuum tubes as they are not required to be filled with large quantities of water. Even if some of the solar evacuated tubes break, the solar system won’t shut down fully. Rather the undamaged collectors will continue to operate until the damaged ones get replaced. However, the performance and efficiency of the solar evacuated tube system differ with a number of factors, including the hot water requirement for each household, outside air temperature, solar collector/roof pitch, collector orientation, and seasonal variation. Buyers always have the option to purchase 20 evacuated tube collectors or 30 evacuated tube collectors which often come included in the package with the frame to mount it on the roof. The desired type of collector can be used individually or connected in series with others to make larger solar systems for producing large volumes of hot water with solar energy.

Take Advantage of Highly-Efficient Solar Water Heating Systems

February 5, 2018 - No Responses

Solar water heating systems are also known as solar domestic hot water systems. They can be the affordable way to generate hot water for your home. Solar water heaters are used in any climate, and the fuel they use – sunshine is free of cost.

How Solar Water Heating Systems Work?

Solar water heating systems comprise of solar collectors and solar water tanks for storage. However, there are two types of solar water heating systems – active, which have circulating pumps and controls, and passive – which don’t have.

Active Solar Water Heating Systems –

There are two types of active solar water heating systems: direct circulation systems and indirect circulation systems.

Direct Circulation Systems – In the direct circulation systems, pumps circulate household water through the collectors and into the home. They work very well in climates where it rarely freezes.

Indirect Circulation Systems – Generally, pumps circulate a non-freezing, heat transfer fluid through the collectors and a heat exchanger. It helps in heating the water and flows throughout the home. These systems are popular options in climates – prone to freezing temperatures.

Passive Solar Water Heating Systems –

Passive solar water heating systems are usually less costly as compared to active systems, but they’re not more efficient than its counterpart. However, passive systems can be more reliable and may last longer.

There are two types of passive solar water heating systems: Integral collector-storage passive systems and Thermosyphon systems.

Integral Collector-Storage Passive Systems – These passive systems work very well in climates where the temperatures rarely fall below freezing. In addition to, they work best in a household with significant daytime and evening hot water requirements.

Thermosyphon Systems – The water flows through this system when warm water rises as cooler water sinks. The collector should be installed below the storage tank so that the warm water will rise into the solar water tank.

These systems are considered to be reliable, but contractors should focus on the roof design because of the heavy storage tank. Please keep in mind that they are more expensive than integral collector- storage passive systems.

Solar Collectors –

There are two types of solar collectors used for residential applications:

Flat-Plate Collector – Glazed flat-plate collectors are insulated; weather-proofed boxes contain a dark absorber plate under one or more glass or plastic covers.

Unglazed flat plate collectors are used for solar pool heating systems and have a dark absorber plate, made of polymer or metal without any cover or enclosure.

Evacuated Tube Solar Collectors – Evacuated tube solar collectors feature parallel rows of transparent glass tubes. Every tube comprises of a glass outer tube and metal absorber connected to a fin.

The coating of fin absorbs solar energy and inhibits radiative heat loss. These collectors are used frequently for most of the U.S. commercial applications.

Solar Water Tanks –

Most solar water heating systems require a perfectly-insulated storage tank. Solar water tanks feature an additional outlet and inlet connected to and from the collector.

The solar water heater preheats water before entering the conventional water heater in two-tank systems. But in one-tank systems, the backup heater is combined with the solar storage in a tank.

The solar water tanks are the critical components of solar thermal systems. These tanks allow the system to provide hot water at any time of day, whether the sun is shining or not, since the solar production doesn’t coincide with the peak periods of hot water demand, using in the morning and evening.

Solar Photovoltaic Panels – How They Work?

May 15, 2017 - No Responses

Installing a solar-powered panel for your home is the best way to save on the electricity expenditures and have access to the safe & clean power that we all wish for negligible environmental impact. Once you’ve learned how solar PV panels function, you’ll be well on your way of building & fitting your homemade solar-power unit.

A PV solar panel unit functions like other power generating unit, except it employs different tools than a typical power system. The particular components employed in a PV system encompass a DC-AC power inverter, system & battery controller, battery bank, and auxiliary energy supplies. Batteries are a crucial compound and are employed for storing power generated by the system throughout the day, and to supply it to electric appliances as required. How solar PV panels operate is a matter of basic science, where the panels convert the solar energy into electrical energy.

These days everyone own calculators that feature solar cells. They never require batteries & are powered from light. As long as you’ve adequate light, they look to function with great efficiency. Larger solar-panels are everywhere – on emergency road signs and even on light poles to illuminate street lamps.

PV cells are composed of silicon semiconductors, and when light come in touch with the cells, it’s absorbed into the semiconductor substance. The energy frees electrons enabling them to flow independently. This flow of electron is a current, and by putting metal contacts on the bottom and top of the solar PV cell, electrical energy can be extracted to be employed externally.

Advantages of  Solar Photovoltaic Panel:

  • Photovoltaic cells run even in adverse weather condition (cloudy climate)
  • Operating & maintenance expenses for PV panels are considered to be low compared to the price of other renewable energy systems.
  • PV cells are absolutely silent & don’t have any mechanically moving parts making them an ideal solution for residential sites.
  • Solar Photovoltaic is eco-friendly as when solar panels produce electrical energy there’re no emissions discharged.
  • The Solar Panels are available to various sizes to meet the voltage requirements of a hose or premise.
