Optimisation for Business and Homeowners

Optimisation of a Solar PV and Battery Storage System for Businesses & Homeowners

Optimisation in a solar PV and battery storage system means using advanced strategies and smart technology to maximize energy efficiency, reduce costs, and increase sustainability. Whether for businesses or homeowners, optimisation ensures that solar energy is used, stored, and managed in the most effective way.

🔋 Key Optimisation Strategies for Businesses & Homeowners

1️⃣ Maximise Solar Self-Consumption

✅ Without optimisation: Excess solar power is sent to the grid at a low rate, while energy is later bought back at a higher cost.

✅ With optimisation: A smart Energy Management System (EMS) ensures that solar energy is used in real time or stored in batteries for later use.

🔹 Benefit: Less reliance on the grid = lower energy bills.

2️⃣ Smart Battery Charging & Discharging

✅ Without optimisation: Batteries may charge and discharge inefficiently, reducing lifespan and savings.

✅ With optimisation:

  • Batteries charge when solar energy is abundant or when grid electricity is cheapest (off-peak tariffs).
  • Batteries discharge when grid prices are highest, reducing peak demand costs.

🔹 Benefit: Cuts energy costs by up to 30-50%.

3️⃣ Load Management & Peak Shaving

✅ Without optimisation: Energy-intensive appliances run simultaneously, increasing demand charges.

✅ With optimisation:

  • The EMS schedules high-energy devices (EV chargers, HVAC, machinery) to run during solar production or off-peak hours.
  • Reduces electricity consumption during high-demand periods, lowering grid costs.

🔹 Benefit: Avoids peak-time tariffs and demand surcharges.

4️⃣ Dynamic Tariff & Smart Grid Integration

✅ Without optimisation: Businesses and homeowners pay flat-rate electricity tariffs without considering fluctuations in grid pricing.

✅ With optimisation:

  • Smart EMS systems shift electricity usage to the cheapest tariff periods.
  • In some cases, energy can be sold back to the grid at peak rates for extra revenue.

🔹 Benefit: Save money by purchasing energy when it's cheapest and selling it when demand is high.

5️⃣ Weather Forecasting & AI Predictions

✅ Without optimisation: Battery charging and energy use decisions are based on fixed schedules, ignoring weather conditions.

✅ With optimisation:

  • AI-powered EMS uses weather forecasting to adjust solar and battery usage.
  • If a cloudy day is expected, the system charges batteries in advance using off-peak grid power.

🔹 Benefit: Ensures energy availability and maximises battery efficiency.

6️⃣ Virtual Power Plant (VPP) & Demand Response Participation

✅ Without optimisation: Homes and businesses miss opportunities to earn from excess stored energy.

✅ With optimisation:

  • Some EMS platforms allow participation in Virtual Power Plants (VPPs), where businesses and homes sell surplus energy back to the grid at premium prices.
  • Demand response programs reward businesses for reducing energy usage during peak demand.

🔹 Benefit: Generate revenue while supporting grid stability.

📊 Example: Business vs. Homeowner Savings

Optimisation Strategy Business Savings Potential Homeowner Savings Potential
Maximising Solar Use 30-50% lower bills 20-40% lower bills
Battery Management Reduces demand charges by 40% Reduces night-time grid use
Peak Load Reduction Avoids costly demand surges Lowers expensive grid purchases
Smart Tariff Shifting Thousands saved per year £300-£800 annual savings
Grid Sell-Back (VPP) Extra revenue stream Small profit from excess solar
