💡 Optimisation Tips
- Peak Shaving: Battery charges during low-demand periods and discharges at peak hours, reducing demand charges.
- Self-Consumption: Store excess solar production for later use, maximising savings against grid prices.
- Support Schemes: Check currently open EU co-funded and national subsidy calls via the relevant national agency for your sector.
- Feed-in Tariff: Sell surplus energy during high-price periods for additional income.
- Tax Incentives: Businesses and property owners may access tax relief for qualifying renewable energy investments — consult a tax adviser.
⚠ Important Considerations
- Battery lifespan: typically 10–15 years (replacement may be required during system life).
- Solar panel degradation: ~0.5% output loss per year.
- Grid connection requirements and regulations may vary by region and site type.
- Insurance and extended warranty costs should be added to total expenses.
- Weather variations affect solar production (Lithuania: ~1,000–1,100 kWh/kWp annually).
⚖ Disclaimer — Calculation Results
The figures presented by this tool are estimates for indicative and planning purposes only and do not constitute financial, investment, engineering, or legal advice. All results are based on generalised assumptions including average Lithuanian solar irradiance (1,050 kWh/kWp/year), standard grid emission factors, and simplified demand-charge models. Actual performance, savings, and payback periods may differ materially depending on site-specific conditions, local energy tariffs, regulatory changes, equipment performance, weather variability, and financing terms. Users are strongly advised to obtain a detailed technical and financial feasibility study from a qualified energy consultant before committing to any investment.
