Frequently Asked Questions

What's the payback period for a 300kW EV solar system in Hillingdon?

A typical 300kW system costs approximately £360,000 and generates annual savings of £90,000-£110,000, resulting in a 3.5-4 year payback period. This includes both energy savings and EV charging revenue. With ECO4 grants covering 30-50% of costs, the payback period can be reduced to 2.5-3.5 years.

How many EV charging points can I install with solar?

A 300kW solar system can support 20-30 EV charging points, depending on usage patterns. We design systems to maximize both solar generation and EV charging capacity, often including battery storage for optimal performance. With battery storage, you can support more charging points and provide charging during evening hours when solar generation is low.

Can I charge for EV charging services?

Yes, you can charge for EV charging services. Many businesses charge 25-35p per kWh, providing additional revenue streams. Solar-powered charging is particularly attractive to EV drivers due to its environmental benefits. We provide payment systems and mobile app integration for seamless charging management. Revenue from EV charging can significantly improve system ROI.

What about battery storage for EV charging?

Battery storage systems can store excess solar energy during the day and provide EV charging during evening hours. This maximizes solar utilization and provides backup power during grid outages. Battery storage typically increases solar self-consumption from 70-80% to 90%+, significantly improving ROI. For a 300kW system, a 100-200kWh battery provides optimal performance.

How do I handle planning permission for EV charging infrastructure?

Most EV charging installations are permitted development, but we handle all planning applications as part of our service. We work with Hillingdon Council to ensure compliance with local requirements. EV charging infrastructure typically requires less planning permission than solar installations, making it easier to implement. We handle all permits and approvals as part of our comprehensive service.

How does smart charging work with solar?

Smart charging systems prioritize solar energy for EV charging, automatically adjusting charging rates based on solar generation. During peak solar hours (10am-4pm), charging rates are maximized. During low solar periods, charging can be reduced or scheduled for later. This maximizes solar self-consumption and reduces grid dependency. Smart charging systems also balance load across multiple charging points to prevent overload.

Can I expand my EV charging network in the future?

Yes, our modular design allows for easy expansion. We can add more charging points as demand grows, and increase solar capacity to support additional charging. Future expansions typically achieve even better ROI due to reduced installation costs and existing infrastructure. We design initial installations with future expansion in mind, ensuring scalability.
