In principle, solar collectors can be installed in any unshaded place, on the roof surface, in the roof, on the facade of a building. Also possible "free" installation on the ground. Most importantly, you need a sunny place and a desire to purchase an environmentally friendly, reliable, stable source of energy, which, when prices for traditional energy sources rise, will save significant funds.
Depending on the location of the swimming pool (whether it is indoors or outdoors, covered at night, etc.), the type of fuel replaced and other aspects, the system may start to pay off after 36 months.
Solar collectors are installed on the roofs on the south side or placed elsewhere in the swimming pool in the owner's territory.
The required number of collectors depends on the size of the pool and the specifics of use. The collectors are connected in a closed circuit to a specially designed chlorine-resistant pool heat exchanger. The closed circuit is filled with non-toxic and non-freezing glycol liquid "SolarEko", which also has anti-corrosion properties.
Qualitative, 2 m2 large solar collectors according to the Latvian climate cost not less than 800 EUR / unit.
Since 2007, we have tested several types and manufacturers of collectors and have realized that the most suitable for our climate are manufactured by the German / Slovak joint venture Thermo|Solar, which has the best value for money and invaluable experience gained over 35 years of operation. , scientific research and the implementation of very diverse and complex projects.
Sauleskolektors.lv solar system consists of solar collectors, their connection and connection kits, mounting frame and load-bearing structures, solar boiler or combined boiler - heat accumulator, hydro unit, automation, temperature and pressure sensors, heat carrier fluid, stainless steel or copper pipes with heat insulation and consumables.
This system has two essential parts: a heat pump with large heat exchangers and flat vacuum solar collectors.
It is an effective combination. On sunny days, unused heat from the solar collectors is discharged directly to the ground, but when there is not enough direct solar energy, the heat pump "pumps it" out of the ground. Thus, the sun heats the house, the water in the boiler and the swimming pool, if any. The "solar heat pump system" prevents the ground circuit pipes from freezing, which is often the cause of the inefficiency of conventional heat pumps.
There was a Song Festival in Latvia, where the closing concert was called "Latvia - the Land of the Sun". In Latvia, the sun shines more than, for example, in Denmark, which ranks 5th in terms of the area of solar collectors per capita in Europe.
Already now in Latvia it is possible to use solar collectors for basic heating, fully supplying the house with heat and hot water from solar energy. This type is called a "solar heat pump system". The average efficiency for such a system is 8.
The roof plane should be large enough and oriented as far south as possible. The east-west and west-facing roof planes are also suitable for solar panels. The slope of this plane should be 60 (+/- 15) degrees.
The roof can also be flatter, but then the collectors will have to be mounted above the roof. Trees that could obscure solar panels after 20-30 years should not be planted in front of the house. As sauleskolektors.lv collectors are light and as durable as the roof, they are suitable for practically any roof. If there is no space on the roof or it is too shaded, solar panels can also be placed on the wall of the building or on the ground.
There are several ways in which sauleskolektors.lv creates solar systems for heating support, depending on the type of main heating of the building. The solar system for heating support also provides water heating from the sun. The most commonly used type of solar heating support system in Latvia is with a heat accumulator. In such a system, the hot water boiler is first heated from the sun, then the system automatically switches and heats the heating heat accumulator.
In order to use solar collectors for heating support, it should be remembered that the system will need 2-3 times more than hot water, but during the summer, if there is no rational use of heat, such as a swimming pool or heated basement, the equipment will be idle.
If someone promises you that a 10 m2 absorbing surface will be able to heat a 100 m2 terraced house, then you know - you are lying lying in front of your eyes.
There are collectors consisting of vacuum tubes made of very thin (1.4-2mm) borosilicate glass. Virtually all factories producing vacuum tubes are located in China, where this type of solar collectors are the most common. Their impact resistance is insufficient for the Latvian climate, where there are regular storms that break branches and lift various objects into the air. Hail grains in Latvia also tend to reach dangerous sizes for vacuum tubes.
