With the cost of electricity rising and a greater focus on sustainable living, more homeowners in Bishop’s Stortford are choosing to invest in solar panels.
But before installing a solar PV system, it’s important to ensure your home’s electrical system is ready to handle the upgrade safely and efficiently. At JJB Electrical Ltd., we help homeowners across Bishop’s Stortford prepare properly for solar panel installation — avoiding costly surprises and ensuring you get the best performance from your system. In this guide, we’ll explain what preparation is needed, how to check if your home is solar-ready, and how we can help you every step of the way.
Why Preparing Properly for Solar Panels Matters
Installing solar panels is a major investment, and preparation is key for:
- Safety: Solar systems introduce additional electrical loads and generation points into your home.
- Efficiency: A properly prepared system performs better and delivers maximum savings.
- Compliance: Installations must meet current wiring regulations (BS 7671) and planning guidelines.
- Future-Proofing: Preparing now makes it easier to add battery storage or EV charging later.
Skipping preparation can lead to expensive remedial work later — or even system underperformance.
Key Steps to Prepare Your Home for Solar Panels
1 - Assess Your Roof’s Suitability
Solar panels perform best when they have:
- A south-facing, unshaded roof
- A tilt angle between 30 and 40 degrees
- Strong structural integrity
Roof inspections should assess:
- Size and layout: Enough space for the number of panels you want.
- Roof condition: Panels can last 25+ years — roof repairs are best done before installation.
- Shading: Trees, chimneys, or nearby buildings can affect output.
We recommend you work with your solar installer to confirm roof readiness — but knowing these basics helps your planning.
2 - Check Your Consumer Unit (Fuse Box)
Modern solar systems must connect safely into your home’s electrical distribution system. If your consumer unit is outdated, you may need an upgrade.
Warning signs your consumer unit may not be ready:
- Old fuse wire system
- No RCD protection (essential for safety)
- Limited spare ways (spaces for additional circuits)
At JJB Electrical Ltd., we can inspect your consumer unit and upgrade it to meet all current regulations, ensuring it can handle your new solar system safely.
3 - Review Earthing and Bonding
Solar installations require robust earthing and bonding to prevent electric shocks or fire risks. We’ll check:
- Main earth connection to the consumer unit
- Bonding of incoming gas, water, and oil services
- Earth rods or earth electrodes if required for external inverters
Without proper earthing, your solar system could be dangerous and non-compliant.
4 - Plan for Smart Meter and Solar Export
Modern solar systems often connect to the grid, allowing you to sell excess power back to your energy supplier.
For this to happen efficiently, your home needs:
- A compatible smart meter (SMETS2 standard)
- A solar-ready energy tariff
If you don’t have a suitable smart meter yet, we can help liaise with your supplier to arrange one.
5 - Future-Proof for Battery Storage and EV Chargers
Solar panel systems are increasingly paired with:
- Home battery storage: Saving excess energy for night-time use.
- EV chargers: Charging your electric vehicle with solar energy.
- Future-proofing your electrical installation now saves money later by avoiding disruptive reworks.
At JJB Electrical Ltd., we can advise on battery-ready consumer units and dedicated EV charger circuits to make future expansion easy.
Common Electrical Upgrades Before Solar Installation
Depending on your home, we often recommend:
- Consumer unit upgrades (modern RCBO boards with surge protection)
- Installing an external isolator switch (for safe maintenance)
- Upgrading main bonding to water and gas
- Installing a Generation Meter (to track your solar energy production)
Every home is different — that’s why we tailor solutions to your specific needs.
How Long Does Solar Preparation Take?
Typical timescales:
- Consumer unit upgrades: 1 day
- Earthing and bonding upgrades: Half to 1 day
- External isolator installation: Half a day
In most cases, electrical preparation is completed within 1–2 working days — ensuring your solar installer can move forward smoothly.
How Much Does Electrical Preparation for Solar Cost?
Costs vary depending on:
- Property size and complexity
- Number of circuits
- Condition of existing wiring
Typical ballpark figures:
- Consumer unit upgrades: from £750
- Bonding upgrades: from £150
- External isolator installation: from £120
