TECHNICAL FIELD

The Invention Is a method and apparatus for storing solar energy. Solar energy is provided by solar panels, and the invention provides solar energy stored as a thermal energy.

BACKGROUND OF THE INVENTION

Solar energy panels and the transferring of electrical energy as direct or alternation currents are known as well as controllers and electric accumulators. The system does not need direct sunlight, and the system also generates electrical energy on cloudy days, and the radiation of the sun is also considerably available in cold times.

Over the years, a lot of research has been done for storing solar

energy. The most common way of storing solar energy is to water, but this causes often complicated systems and the occurring risk because of low boiling water temperature. One solution is disclosed in WO2016197663 Hot water heating device having solar energy and off-peak electric heating energy storage and application.

The storing of solar energy is also used by pumping transferring a molten metal. One solution is in a patent publication EP1816176 Latent heat storage devices and one solution in a patent publication

WO2017221197 A solar energy capture, energy conversion and energy storage system, which discloses the use of phase change material for storing thermal energy, but it does not disclose the use of phase change material for energy transferring to the main heat storing material such as brick or rock. SUMMARY OF THE INVENTION

The invention relates to a method and an apparatus for transferring electrical energy from solar panels into by soldering (1) to a molten metal (2) and transferring the thermal energy to the main heat storage material or materials (3), such as brick or stone. Over the years, a lot of research has been done to store solar energy, but there are

limitations and problems in the existing systems. FIGURES

Figure 1

The solar panel generates electrical energy, the jacket prepares for thermal energy in a thermally insulated module that stores heat. The module is supplied with electricity by soldering (1) a part of a 10 mm thick tin (2) with brick statues (3) separated from the bottom of the thermal module by a non-melting metal grid inside the melting tin, and there is air between the brick statues. The thermally insulated module has an overpressure valve to allow, for example, any moisture from the brick to escape. The thermally insulated module, if necessary, has a hatch (5) with a metal plate, if necessary, to provide faster heat to the room or other space. The solution resembles a charging fireplace and a stove.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The electrical energy from the solar panels is stored in a heat storing module. Solar panels are known to provide electrical energy, which is direct current and can be converted to alternating current if desired by an inverter. Controls are also often included in the system.

Electricitv is supplied to the soldering part, where the electrical use a short circuit solution.

The soldering solder head may be wider than the typical soldering flask.

It is preferred that the metal melt rapidly if the heat transfer is enhanced and thus the molten metal layer is typically 1-1000 mm thick. The molten metal is typically a non-toxic tin, but the closed module can include lead.

The closed thermocouple has brick or stone tiles so that the air can effectively circulate in the heat module. It is possible to remotely air the holding of a wholly or partially digestible metal.

The main storing material, such as brick, may contain moisture, and thus there is an overpressure valve in the heat module. The heat module has an automatic and / or manually openable door with a metal plate, if necessary. From the opened door, heat energy is released faster from the heat module.

The same heat module can also be connected to the power grid, whereby the same device operates with both a solar panel and, if necessary, another power source. For example, the daily electricity price may be cheaper than the overnight electricity, and so it is worthwhile to reserve the heat module with daytime electricity. A peltier fan or other fan may also be used on the heat module if faster heat transfer to the room or other space is desired.
