Solar installations are the future of renewable energy. At Onninen we offer comprehensive systems for obtaining solar energy. Our solutions work well in both single-family homes and large commercial facilities. We take care of the highest quality components and professional technical advice.

Our offer includes a wide range of products for solar installations:

Flat and vacuum solar collectors
Complete solar kits
Pump groups and controllers
Tanks and heat exchangers
Pipes, fittings and assembly accessories

We are often asked about selecting the right system. It is crucial to precisely determine the demand for hot water. We also analyze the sunlight conditions and available mounting space. Based on this, we propose the optimal solution.

Solar installations - top quality components

At Onninen, we focus on proven brands and innovative technologies. We offer products from renowned manufacturers such as Immergas, Heatpex and Afriso. We especially recommend our own brands: Onnline and Opal. They guarantee excellent value for money.

Our assortment includes, among others:

Safety valves and solar vents
Solar fluids with different parameters
Pre-insulated steel pipes and insulated solar pipes
Coupling sets, pipe nuts and compression fittings
Temperature sensors and regulators

Our experience shows that the key is to properly select all system components. That's why we offer comprehensive solar kits that include all the necessary components. This makes installation easier and guarantees optimal system performance.

Solar installations - practical applications and benefits

In everyday practice, we observe a growing interest in solar installations. This is due to the many benefits that these systems offer. First of all, they allow for a significant reduction in the costs of water heating. In a typical household, a solar installation can cover up to 70% of the annual demand for hot water.

We recently completed a project for a large seaside hotel. We used a system of 50 Immergas solar collectors. This allowed us to reduce annual energy costs by over 30%. The investment paid off after just 4 years. This shows how effective solar installations can be in facilities with high hot water consumption.

Many customers ask us about the possibility of integrating a solar system with an existing heating installation. This is a perfectly possible and frequently practiced solution. Our Onnline pump groups enable easy connection of collectors to the hot water tank. They work with most boilers and heat pumps available on the market.

In the case of modernization of older buildings, we especially recommend compact solar sets. They contain all the necessary elements in one housing. This makes installation easier and saves space in the boiler room. This solution works great in tenement houses or buildings with limited technical space.

Solar installations - professional support at every stage

At Onninen we provide comprehensive services in the field of solar installations. Our technical advisors will help you choose the optimal solution. We offer support at the design stage, component selection and assembly. We also organize training for installers to ensure the highest quality of workmanship.

Our experience shows that precise dimensioning of the installation is crucial. A system that is too small will not provide the expected savings. Over-dimensioning, on the other hand, will increase investment costs and may lead to overheating of the system. That is why we always conduct a thorough analysis of the customer's needs.

Onninen recommends using high-quality solar fluids. They provide protection against freezing and overheating. Our Onnline solar fluids guarantee many years of trouble-free operation of the installation. They are biodegradable and safe for the environment. This is an important aspect that is often forgotten by less experienced installers.

In the case of larger investments, such as housing estates or industrial facilities, we offer individual solutions. Our engineers design solar systems adapted to the specifics of the facility. We also take into account the possibility of expanding the installation in the future. This allows for the phased implementation of the investment and cost optimization.

Solar installations not only save money, but also protect the environment. Every kilowatt of energy obtained from the sun means less fossil fuel burned. Over the course of a year, even a small installation can reduce CO2 emissions by several tons. This is a real contribution to the fight against climate change.

We invite you to contact our specialists. We will help you choose the optimal solar solution for your needs. At Onninen you will find all the necessary components of the highest quality. We also provide expert advice and technical support at every stage of implementation.
