Designing a system that combines solar thermal energy and biomass (wood, pellets, or chips) means aiming for efficiency, savings, and sustainability. In this article, we will see how does it work a solar-biomass hybrid system advantages and the incentives currently available. Since 1997, we have been designing and installing renewable energy systems in Corciano, Perugia, and throughout Umbria to ensure comfort, reliability, and real energy savings for those who choose sustainable solutions for their homes.
What is a solar-biomass hybrid system?
A hybrid solar-biomass system involves the integration of two technologies powered by renewable sources for the production of thermal energy (heating and/or domestic hot water):
- one solar thermal system that captures the sun's energy;
- one biomass boiler (wood, pellets o chipped) which intervenes when the sun's contribution is not enough.
Essentially, solar thermal collectors preheat the water (or part of the system), while the biomass boiler comes into operation on days with less sun, during peak demand, or in the winter months. In Italy, the intelligent integration of combined solar-biomass solutions can lead to consumption reductions consistent Up to 60% % compared to a traditional system.
In Umbria, where solid biomass (firewood and pellets) is an easily accessible resource, a hybrid system represents a particularly effective choice. According to recent data, Thermal RES (i.e. renewable sources for heat production) covered in Italy in 2023 21,7 % of the national thermal requirement.
How does the integration between a solar thermal system and a boiler work
To understand why a hybrid system is so advantageous, it's useful to know how solar thermal and biomass boilers work together. Their integration allows for maximum utilization of free solar energy and ensures continuity and efficiency thanks to wood, pellets, or wood chips.
L’solar thermal system consists of collectors installed on the roof or in a sunny location, a heat transfer fluid that carries the heat, and a tank (buffer) that It accumulates heat to then produce hot water via a heat exchanger.
La biomass boiler (wood, pellets e chipped) burns renewable fuel, producing heat that can power the storage tank itself or directly intervene in the system.
In the hybrid system:
- The solar thermal collector provides heat on sunny days and during intermediate periods;
- During hours or days with low solar radiation, the biomass boiler automatically engages to cover the thermal demand.;
- A well-sized tank/buffer allows for heat accumulation, optimizes biomass usage, and extends the time between refills.
Smart management allows for maximizing free solar energy and reducing fuel consumption. Thanks to this logic, a hybrid system is more efficient, less affected by climate, and performs better than a single solution.
The advantages for those who install a solar-biomass hybrid system
Installing a solar-biomass hybrid system means obtaining a more efficient, economical, and reliable thermal system throughout the year. In the months from April to September, Solar thermal can entirely cover the domestic hot water needs., allowing the boiler to be turned off, while in winter or on cloudy days Biomass guarantees continuity of service. Thanks to modern advanced control systems, based on predictive models Weather forecasts, today it's possible to optimize consumption even better, reduce waste, and prioritize solar energy. All of this translates into numerous concrete advantages, making the hybrid system one of the most convenient solutions for those living in Umbria who desire truly sustainable heating.
Advantages:
- Reduction of energy consumption: by combining renewable sources such as sun, wood, and pellets, a mix is obtained that greatly reduces dependence on fossil fuels and energy bill costs, guaranteeing up to 60 % savings compared to traditional systems.
- Greater efficiency and continuityThe hybrid installation ensures that the system works well even during periods of low sunlight thanks to the intervention of biomass. This avoids the risk of solar power being insufficient in the cold months or on cloudy days.
- Renewable energy and environmental sustainabilityThe combined use of a solar thermal system and a biomass boiler (wood, pellets, or wood chips) means reducing CO₂ emissions and using local renewable sources.
- Valorization of the local supply chainIn Umbria, the use of firewood and pellets benefits the local economy, local supply, and short supply chains: a technical and economic advantage.
- Property Location and ValueA solar-biomass hybrid system improves a building's energy rating, promoting both thermal comfort and resale or rental potential. From a property valuation perspective, it is a strategic plus to consider.
Incentives available for the installation of solar-biomass hybrid systems
The incentive system for thermal renewable energy sources currently offers several opportunities for those who wish to install a solar-biomass hybrid system. Among the most relevant measures, we find the Conto Termico 3.0, which in its latest updates also includes high-efficiency biomass generators and hybrid or bivalent systems. This incentive often represents the most significant contribution to the installation of the biomass component, ensuring concrete financial support.
Alongside the thermal account, the tax deductions, such as Ecobonus and Bonus Casa, which offer advantageous rates for interventions on existing buildings. It is also possible that dedicated calls for tenders for biomass or solar thermal energy may be activated at the local or regional level.
In most cases, installing a hybrid system to replace gas, LPG, or oil boilers can be amortized over 4 to 10 years. The main barrier remains the initial cost, but there are tools that can significantly reduce it.
One of these is the irrevocable collection mandate Conto Termico, managed directly by the installer: allows for an immediate discount on the invoice, reducing the initial outlay. With the new Conto Termico, which is expected to recognize up to for individuals 15,000 € in a lump sum, this mode will become even more advantageous.
Another useful tool is the financing, which allows the investment to be transformed into an easily sustainable annual installment, often largely covered by the energy savings generated by the system itself.
Energy Saving supports the customer at every stage: from choosing the most convenient incentive to the complete management of paperwork, up to the design and installation of the system. Furthermore, we are one of the few companies in Umbria to offer the immediate discount on the invoice for the Thermal Account, immediately reducing the financial outlay and making the investment even more advantageous.
Why rely on an industry professional
Installing a solar-biomass hybrid system means choosing an efficient, sustainable, and capable solution ensure energy savings throughout the year, making the most of the free energy from the sun and the continuity offered by wood, pellets, and wood chips. To achieve these results, it's essential to rely on qualified professionals.
Since 1997, Risparmio Energetico has been a benchmark throughout Umbria for the design and installation of systems powered by renewable sources, thanks to an approach turnkey: from initial analysis to incentive management, from custom design to installation, through to ongoing maintenance and technical support. Each system is designed to ensure comfort, efficiency, and maximum performance.
