Domestic Solar PV in East London: Is Your Home Suitable and What Will It Save You?

5 April 20269 min readKLIC ELECTRICAL

Solar panels are now one of the best home investments available in the UK. But is your East London property suitable? Here's an honest guide to domestic solar PV — from roof suitability to MCS certification and SEG payments.


Solar PV has become one of the most talked-about home improvements in East London over the past two years — and for good reason. With electricity prices remaining high and the Smart Export Guarantee (SEG) paying homeowners for surplus power they export to the grid, a well-designed solar system can genuinely transform your energy bills. But is your East London property actually suitable for solar panels?

Is My East London Property Suitable for Solar Panels?

Roof Orientation

A south-facing roof at 30–35 degrees generates the most solar energy in the UK — typically around 3,400 kWh per year for a 4kWp system. East or west-facing roofs can still produce around 80–85% of a south-facing system's output, making them viable. North-facing roofs are generally not recommended for solar PV in the UK, as generation drops significantly. During your free survey, we assess your specific roof orientation and model your expected generation honestly.

Shading

Shading is one of the most important factors in solar PV performance. Even partial shading from a chimney, tree, or neighbouring building can significantly reduce generation — particularly with string inverter systems. In East London, where terraced properties are common and neighbouring buildings are often close, shading analysis is a critical part of our survey process. Where shading is an issue, we may recommend microinverters or power optimisers to minimise its impact.

Roof Condition

Solar panels are designed to last 25+ years, so your roof needs to be in good condition before installation. If your roof is due for re-tiling or has structural issues, it's better to address these before installing panels. We assess roof condition during our survey and will advise if any remedial work is needed first.

How Much Can Solar Panels Save in East London?

A typical 4kWp domestic solar system in East London generates around 3,400 kWh per year. At current electricity rates (around 24–28p/kWh), that represents a saving of approximately £800–£950 per year in electricity you no longer need to buy from the grid. On top of this, the Smart Export Guarantee (SEG) pays you for every unit of surplus electricity you export — typically 4–15p/kWh depending on your supplier.

  • 4kWp system: ~3,400 kWh generated per year
  • Electricity saving: ~£800–£950 per year (at 24–28p/kWh)
  • SEG export income: ~£100–£300 per year (depending on usage pattern and supplier)
  • Total annual benefit: ~£900–£1,250 per year
  • Typical payback period: 7–10 years
  • System lifespan: 25+ years

What Is MCS Certification and Why Does It Matter?

MCS (Microgeneration Certification Scheme) certification is the industry standard for domestic solar PV installations in the UK. It is not optional — it is the only way to access the Smart Export Guarantee (SEG), which pays you for exported solar energy. Without MCS certification, your energy supplier cannot pay you for exported power, costing you hundreds of pounds per year.

MCS certification also validates your panel and inverter warranties. Most manufacturers require the installation to have been carried out by an MCS-certified contractor to honour their 25-year performance warranty. KLIC ELECTRICAL is MCS certified — every domestic solar installation we carry out in East London is fully MCS certified as standard.

Can I Add Battery Storage to My Solar System?

Battery storage is an excellent addition to a solar PV system that allows you to store the energy you generate during the day and use it in the evening when panels are not generating. Without battery storage, surplus energy is exported to the grid (earning you SEG payments). With battery storage, you can use that energy yourself — at a higher value than the SEG export rate.

We install leading battery systems including GivEnergy, Tesla Powerwall, and Solax alongside solar installations or as a retrofit to existing systems. A typical 5–10kWh battery system costs £2,500–£5,000 installed and can significantly increase your solar self-consumption rate.
