Solar Panel and Battery Solutions for Businesses: How to Choose the Most Suitable One?

Companies are increasingly looking for ways to reduce energy costs, enhance energy security, and generate revenue using new business models. Combining solar panels with energy storage (batteries) offers several flexible solution options for this. Below, we provide an overview of the main possibilities and outline the criteria for evaluating such solutions.

‍

Solar panels for reducing daytime consumption

🔅

The simplest and most affordable solution for companies looking to reduce electricity purchases from the grid specifically during the day – when prices are typically higher.

Benefits:

• Immediate savings on electricity bills.
  
• Less dependence on electricity market prices.
  
• Low maintenance and long lifespan (25+ years).
  

Suitable for a company that:

• Consumes a lot of energy during the day (e.g., manufacturing, logistics centers, office buildings).
  
• Does not want to invest in energy storage.
  
• Wants to start step-by-step and keep the initial investment low.
  

Solar panels + battery: cost reduction and energy backup

🔅+🔋

Adding a battery to the system increases a company's control over energy usage. A battery allows for smoothing out grid fluctuations, utilizing stored energy during peak prices, and ensuring reliability for critical systems during power outages.

Benefits:

• Lower energy costs through smart charging and discharging.
  
• Protection against power outages
  
• Less load on the main breaker and potential savings on grid connection costs.
  

Suitable for companies that:

• Needs a continuous electricity supply (e.g., production, cold storage infrastructure, server rooms).
  
• Wants to reduce peak consumption costs.
  
• Wants to make the energy system more reliable.
  

Solar panels + battery solutions for the frequency market

🔅+🔋+ 💵

The energy storage system is capable of providing fast balancing services (FCR, aFRR, mFRR) to the electricity grid, for which market-based fees are paid. When combined with solar panels, a company can reduce its energy costs to near zero or even generate additional revenue.

Benefits:

• Opportunity to earn stable additional income every day.
  
• The battery's payback period is significantly shortened.
  
• The company contributes to more environmentally friendly energy solutions and grid stability.
  

Suitable for companies that:

• Wants to turn its energy system into a revenue-generating asset.
  
• Is ready to invest in a larger battery solution.
  
• Consumes energy moderately or wants to maximize the benefits of solar panels.
  

4. Solar panels + battery for frequency market production with energy reserve

🔅+🔋+ 💵 + 🔒

The most comprehensive solution where the battery serves both a commercial and consumer-centric role: earning revenue in the frequency market while simultaneously retaining a portion of its capacity as critical internal backup.

Benefits:

• Dual benefit: revenue from the frequency market + reliability during outages.
  
• Greater flexibility in managing energy use.
  
• Best return on investment if the company has both market readiness and high reliability requirements.
  

Suitable for a company that:

• Requires a reliable energy backup, but also wants a faster return on investment.
  
• Has energy-intensive processes that must not be interrupted.
  
• Seeks a long-term and strategic energy solution.
  

5. How to choose the most suitable solution for your company❔

Finding a suitable energy solution depends on three main factors:

A) What is your company's energy consumption profile?

• Do you consume more during the day or at night?
  
• Do you experience peak consumption spikes?
  
• How critical is uninterrupted power / Do power outages occur?
  

B) What is the company's goal?

• Only reducing costs? → Solar panels + batteries
  
• Increasing reliability? → Battery reserve and/or solar panels
  
• Generating revenue? → Solar panels + batteries in the frequency market
  
• Maximum control + revenue + backup → Solar panels + battery in frequency market + backup circuit (battery reserve)
  

C) What is the budget and expected return on investment?

Adding a battery increases the initial investment, but it pays for itself faster if it also participates in the frequency market. The payback period for solar panels is 5–9 years; for batteries, it depends on the model and usage. Solar panels combined with batteries are the most cost-effective option, with a payback period of 3-5 years.
