Increase photovoltaic self-consumption

Companies are increasing their self-consumption by combining PV systems with large-scale battery storage to bridge periods without sunlight. For maximum cost-effectiveness, the system should generate approximately 25% more electricity than the annual demand, which sustainably minimizes grid fees, electricity taxes, and CO₂ costs.

Photovoltaics Own consumption (PV electricity) is a decisive factor for companies in reducing energy costs and increasing their independence from the power grid. Especially through the use of Large battery storage systems excess energy from your own photovoltaic system or other renewable sources can be stored and used at a later date.

Advantages of integrating battery storage into photovoltaic systems

The ability to store energy produced and use it when needed is a major advantage when combining photovoltaic systems with battery storage systems to increase self-consumption. This is particularly advantageous at times when the sun is not shining or when Dark doldrumswhich drive up the price of electricity. This means that operators have to purchase less electricity from the grid and can Reduce energy costs. The higher the self-consumption rate, the less electricity tax, Grid charges and CO₂ certificates are incurred.

Another advantage is the improved Network independence. Companies that have a suitable storage solution can maintain more critical operations, even during temporary power outages. This ensures stability in the event of future energy price fluctuations and increases the company's competitiveness.

Correct dimensioning of the PV system to increase self-consumption

If the large-scale battery storage system is only used to increase self-consumption from your own photovoltaic system, the PV system should ideally have around 25% more power than the company's annual consumption. This means that sufficient energy is available for storage charging and self-consumption. CUBE CONCEPTS analyzes the load profiles, electricity tariffs and possible PV areas in order to determine the right size of PV system and storage unit. Modern simulation tools are used to plan according to demand and thus achieve the highest economic benefit.

Optimize consumption behaviour & use energy management systems (EMS)

A Energy management system (EMS), like the CUBE EfficiencyUnitThe system also optimizes self-consumption of photovoltaics by operating power-intensive machines and appliances during the hours of sunshine. It ensures that large-scale battery storage, machines and other consumers are coordinated in the best possible way to achieve maximum self-consumption. An EMS can increase self-consumption by 10 to 20%. The combination of these measures leads to a more efficient use of solar energy and helps companies to sustainably reduce their operating costs.

Reduce fossil fuel consumption to increase photovoltaic self-consumption

The reduction of fossil fuels in the company also increases the self-consumption of photovoltaics. One efficient option is the Integration of heat pumps or Infrared heaterswhich use the surplus solar power and are controlled by the EMS. This enables environmentally friendly heating and cooling of buildings and an increase in self-consumption of up to 20%. The same effect has a Hot water preparation through PV electricity or the switch to Electromobility. Both not only reduce dependence on fossil fuels, but also sustainably reduce operating costs and significantly increase self-consumption.

Battery storage systems increase photovoltaic self-consumption

The combination of photovoltaics and battery storage is an ideal solution for companies to maximize their own consumption of solar power and reduce operating costs at the same time. By implementing these technologies, companies set a strong example for sustainability, promote their independence from external energy suppliers and actively contribute to climate protection.

Investments in these technologies are not only future-oriented, but also a decisive step towards a sustainable and economical energy supply for companies of all sizes.

Tilt angle for solar modules

In Germany, the optimal tilt angle is usually between 30 and 40 degrees with south-facing orientation to maximize annual yield. While steeper angles (up to 45°) are advantageous in the north, flatter settings suffice in the south, where the important self-cleaning of the modules by rain begins at 12 degrees.
