If you’re considering solar panels, one of the first questions is “How many solar panels can I actually fit on my roof?” At SolarTherm UK we’ve helped thousands of homeowners across Essex, Kent, London and the wider South East design efficient solar systems, tailored for their property, the answer will always depend on your roof – the size, shape and any obstructions.
This article will explore the ways in which SolarTherm UK measure your roof for solar, from quick satellite tools to full technical surveys, so you know exactly how we work out how many solar panels you can fit on your home.
Quick Answer: Solar Panel Sizing
- Bovill.tech solar panel size – 1.75m x 1.15m per panel.
- Setbacks required – 0.3m from roof edge, plus same space around chimneys, vents, dormers and skylights.
- Exact panel count depends on roof orientation, usable roof space and any obstructions or persistent shading.
Method 1: Satellite Measuring
At SolarTherm UK, we carry out an initial feasibility study using a satellite tool to check for usable roof space. We look for no-go areas such as chimneys, skylights and dormers, subtract the required setbacks from the edges and design your solar PV system in the remaining space. This initial design will provide the basis for your quote and feasibility.
Method 2: Measuring from Plans
If you live in a new build, are installing onto an extension or re-roofing your property, we can use the building plans to complete your design. Using the dimensions on the plans, setbacks and exclusion areas can be measured more accurately and solar panel orientation can be decided sooner.
Method 3: Measuring in Person
Once you have approved your quote, one of our experienced surveyors at SolarTherm UK will attend your property to carry out a full site survey. Our surveyor will confirm the design will fit, make any adjustments required and check your roof condition and measure for cable routes, inverter positioning and earthing requirements. This ensures your solar PV system is safe, durable and compliant to MCS standards.
Method 4: Drone Survey
For more complex or tall buildings, we will carry out a drone survey at SolarTherm UK to ensure your solar PV system is optimised for efficiency and maximum generation. High resolution drone images allow accurate measurement, shade mapping and parapet heights. For flat roofs we will design optimal inter-row spacing to avoid self-shading.
