Forced Circulation For Solar Water Heater

Forced Circulation For Solar Water Heater

A forced circulation for solar water heater is an installation in which the water circulates inside the circuit driven by a pump. With forced circulation system, the movement of water in the closed circuit is forced by a pump. This feature makes a big difference with respect to sanitary hot water installations with thermosyphon. In this way, it artificially moves the hot water not to the highest point of the closed circuit, but it does so from the solar collectors down to where the accumulator is located.

In many occasions it is not viable to install solar thermal equipment…

Photovoltaic

Photovoltaic

We refer to the photovoltaic effect in everything related to obtaining energy through the action of light.

The most used light source for photovoltaic installations is that coming from the Sun, that is, solar energy. Although there are small devices, such as calculators, that can work with artificial light.

Photovoltaic solar energy

Solar photovoltaic energy is a methodology for obtaining electrical energy thanks to photoelectric cells. It is a renewable energy since its energy source, the Sun, is considered inexhaustible.

Photoelectric cells are the main component…

Solar Accumulator

Solar Accumulator

A solar accumulator is a reservoir that separates the energy supply from the energy capture. That is, because we will not always need energy at the moment of solar radiation, the compiler is entrusted to store this energy to supply it when needed.

For this, the accumulator stores thermal energy from the solar collectors.

When the system needs, for example, domestic hot water the accumulator supplies this hot water and replaces it with cold water that comes from the network. The cold water will pass through the circuit of solar collectors exposed to solar radiation and increase…

Power Accumulators

In the autonomous electricity supply facilities, it is necessary to store the energy captured during the hours of solar radiation in order to cover supply during the hours when there is no (daily cycle and seasonal cycle).

Features accumulators:

  • Electric batteries have a very important and fundamental to the proper functioning and duration of a solar photovoltaic installation function.
  • They must have sufficient capacity to ensure supply of electricity during periods of clouds (autonomy of installation).
  • It is reversible electrochemical systems…

Solar Batteries

Solar Batteries

The batteries in a photovoltaic solar energy system is to accumulate the energy produced by the photovoltaic panels during the hours of Sun to be able to use it at night or on cloudy days.

The use of batteries also allows to provide a higher current intensity than a functioning photovoltaic panel can offer. This would be the case if several electrical appliances were used at the same time.

A battery consists of small 2V accumulators integrated in the same element; Has direct current at 6, 12, 24 or 48V. The accumulator is the cell that stores energy through an electrochemical…

Components Of A Solar Thermal Installation

Components Of A Solar Thermal Installation

The function of a solar thermal installation is to take advantage of solar energy to generate heat. The solar panels of these facilities capture the heat of the solar radiation that falls on them to heat a fluid. The different ways to take advantage of this hot fluid allows us to use this type of renewable energy in multiple applications.

A solar thermal installation consists of:

  • Solar collectors
  • Primary and secondary circuits
  • Heat exchanger
  • Accumulator, pumps
  • Glass of expansion
  • Pipelines
  • Main control panel.

Charge Controllers

Although in principle it seems that in an installation of photovoltaic solar energy just need solar modules and batteries, there is a key element in these facilities is what ensures that, in the charging process as in the discharge accumulators, is made so that they are always within the correct operating conditions: the charge controller.

Solar panels are designed so that they can give a higher than the end voltage battery charging voltage. This ensures that the solar panels are always able to charge the battery, even when the temperature of…

Thermosyphon Solar Systems

Thermosyphon Solar Systems

These equipments have a natural circulation based on convection currents formed in the fluid at different temperatures.

If we heat a water tank at the bottom when the bottom water warms, it becomes less dense and rises to the surface where it cools. Then returns to the bottom of the container and thus a natural circulation flow is generated.

This is the operating principle of a thermosiphon team, which will be essential that:

  • The solar collector (heat sources) is always located below the level of the accumulator.
  • The primary circuit is as short as possible…
