What is necessary for setting up solar collectors on the roof?

Solar collectors can be set up on any building under the sun. If there is no place on the roof they can be mounted on a wall of the building or on the ground. It is important to find a sunny place and goodwill to get stable, safe and environmentally friendly source of energy. System of solar collectors will give you greaterr savings year by year considering rise in prices for conventional fuel and electricity.

How does the system for heating support function?

There are several ways to create solar systems for heating support depending on existing heating. Solar system for heating support includes also water heating. The most popular in Latvia are heating support systems with heat accumulator. In this system the warm water tank has been heated first and afterwards automatically switches to the heat accumulator. We also offer combined tanks – heat accumulators for saving space in boiler room and avoiding breeding of harmful bacteria in warm water.

To provide heating support in Latvian weather conditions at least 10 m2 of solar collectors has to be installed. During the winter solar heating support system will make preheating in combination with existing heating. In spring or autumn during the sunny days system will accumulate enough heat also for the night time. In summer the system is very powerful and additional heat can be used for swimming pool or basement.

Sauleskolektors.lv offers the most appropriate system for particular object for heating support from the sun. Total savings will reach around 30% a year.

Are there any special rules for house construction? Should the roof be built differently?

The roof plane has to be big enough and oriented to the south, also roof planes oriented to the west and east are suitable for the use of solar collectors. The incline of roof plane should be 60 (+/- 15) degrees against horizon. Collectors can be set up also on roofs with less inclined slopes; in this case supporting constructions will be used. Don’t plant trees at the sunny side of the house; they will grow and shade the roof. Collectors from Sauleskolektors.lv are light, strong and suitable for any roof. If there is no place on the roof they can be mounted on a wall of the building or on the ground.

Is there enough sun in our climate for providing house with heat and warm water?

„Latvia- the country of the sun” This was the name of the final concert during the recent Song Festival. Sun in Latvia shines more than in Denmark which is on the fifth place in Europe by area of solar collectors per capita.

Already today sun collectors can be used here in Latvia completely providing the house with heat and warm water exploring solar energy. This technique is called „Solar heat pump system” with average efficiency – 8.

How does the „Solar heat pump system” work for heating?

This system consists of two essential parts: heat pump with large heat exchangers and flat plate vacuum solar collectors from Sauleskolektors.lv. This is a very effective combination. During the sunny days the unused heat is conveyed into the ground warming it up. During the days with lower solar energy heat pump takes the heat back from the ground. Therefore the sun is heating the house, water in the tank or swimming pool. „Solar heat pump system” eliminates freezing of outer parts of pipes. This freezing effect often is a reason of low efficiency of conventional heat pumps.

Flat plate vacuum solar collectors are essential parts of „Solar heat pump system”, they have been produced and installed according to the patented technology and are particularly effective. Only flat plate vacuum collectors from Sauleskolektors.lv can be used in this system, they are safely protected from rising condensation. Other types of collectors may not be used in „Solar heat pump system”.

This system in combination with flat plate vacuum solar collectors can be installed using already existing heat pump essentially improving its functioning.

Very important that energy consumption has been reduced considerably and it will always be lower in comparison with conventional heat pump or any other kind of heating. „Solar heat pump system” completely provides house with heat and warm water, consuming small amount of electricity.

What does the system of solar collectors consist of?

Essential units for installing solar collector system are: solar collectors, supporting constructions, heat accumulator, hydro unit and control panel, heat conveying liquid, isolated pipes and connecting nodes. All the devices and materials used by Sauleskolektors.lv provide long term lifetime and are friendly for the environment.

How much do solar collectors cost?

Appropriate for Latvian climate and qualitative collectors with 2 m2 surface costs about 300 Ls per unit.

After testing several producers of collectors we have understood the most appropriate for our climate collectors are produced in German – Slovakian factory Thermosolar, we offer them for Latvian market already since 2007. We are convinced about good quality products, 35 years experience and technical support what helps us to create efficient systems.

With growth of orders and developed logistics today we can offer prices:

For flat plate solar collector TS300 – Ls 276 +VAT, for flat plate vacuum solar collector TS400 – Ls 501 +VAT.

You should be careful when price offer exceeds Ls 600.

Remember, by setting up solar collectors you are buying amount of energy the solar system will produce during the following 35 years.

How does the swimming pool heating system function?

Solar collectors have been set up on the southern side roofs or other part of the territory. Number of collectors depends on size of pool and using features. Collectors are interconnected in closed circuit with chloride - proof heat exchanger. System is filled with propylene glycol conveying heat transfer fluid SolarEko, harmless and safe for the environment, moreover, it has anti -corrosion properties. The heat is produced when sun radiation through solar glass passes to absorbing surface. When the pool needs to be heated, circulation pump switches on and the heat from collectors goes to the heat exchanger and further to the pool. Heat exchanging is proceeded in a moment before the water is filtered and returned back to the pool. The water in pool will always be heated from the sun if temperature in collectors is higher than in pool.

System will be cost – effective already after 36 months depending on location (inside or outside, coverage at night, etc.)

What is the cost- effectiveness of solar system for pool heating?
