This guide walks you through the process, costs, and benefits of Solar PV system installation London, helping you make an informed decision for a greener, more cost-effective future.

Why Choose Solar PV System Installation London?

With UK energy bills hitting £1,738 annually for households (Ofgem 2025 price cap), Solar PV system installation London offers a lifeline. A 4 kW system can save homeowners £670 yearly, while businesses with 10-50 kW setups can slash costs by up to 50%, per the Energy Saving Trust. The Smart Export Guarantee (SEG) lets you earn up to 30p per kWh for surplus energy—potentially £108 annually for homes and thousands for commercial properties. Plus, each system cuts CO2 emissions by nearly 1 tonne per year per household, supporting London’s net-zero goals. Ready to join the 1.4 million UK solar-powered homes as of late 2024? Let’s explore how Solar PV system installation London works.


The Process of Solar PV System Installation London: Step-by-Step

1. Site Assessment – Finding the Best Spot

Our certified electricians at Yasapo Engineering start every Solar PV system installation London with a thorough site survey. Whether it’s a terraced house in Camden or a warehouse in Croydon, we identify areas with maximum sunlight, avoiding shade from trees, chimneys, or nearby buildings.

2. Mounting Installation – A Solid Foundation

Next, we secure sturdy mounts to your roof or ground, ensuring they withstand London’s weather. For flat commercial roofs, we use adjustable mounts to optimise angles, a key step in Solar PV system installation London for businesses.

3. Panel Installation – Capturing Solar Energy

We install Solar PV panels at a 30-40° angle, ideal for London’s 51° latitude, to maximise sunlight capture. Homes typically need a 4 kW system, while businesses might opt for 50 kW to power offices or factories.

4. Cable Connection – Bringing Power to Life

Cables connect the panels to an inverter and your electrical grid, seamlessly integrating solar energy into your daily life. Add a battery (£5,000-£8,000) to store energy for evening use, a popular option in Solar PV system installation London.
