Switch to Renewable Energy, Start Big Savings
Sunshine is free. Your energy bill shouldn’t be. A solar PV system built for British weather could cut your annual costs by up to £1,080.
How to Start Your DIY Solar Installation
The first step is to evaluate the energy requirements. It is advisable to examine your electricity bills and become aware of how much electricity you use. Once you have done that, you’ll want to determine the number of solar panels you need to install in your home. The number of panels will vary in accordance with the consumption required, roof space and the productivity of the panels.
The orientation of roofs, shading and ideal installation angle of solar panels should be considered. In the UK, roofs typically suit orientation towards the south. Compare various panels, inverters, battery storage and mounting equipment. Choose the appropriate kit to meet your needs.
Please note that installing panels is not the only step in DIY process. Connecting your system to your home circuits requires additional knowledge and safety measures.
DIY Solar Panels and Roof Safety
Solar panels on a roof should withstand wind, rain and weather changes. Proper racking allows keeping the panels in place. But solar panel installation can harm your roof tiles or waterproof layer. Poor mounting can lead to leakage and loose panels.
Falling off the roof is another risk. Working on a roof is extremely hazardous, due to roof top conditions of wet roof tiles and unstable ladders. Before planning your rooftop solar, check the state of your roof and its strength. Do not climb on your roof without appropriate training and safety gear.
Ground-mounted solar panels can be used in case of a lot of free space outside the house. Ground-mounted panels still require proper mounting and electrical protection. Most British house owners prefer the services of a professional installer. An experienced solar installer will check your roof conditions and select the best mounting equipment.

DIY Solar Panels and Electrical Safety
Solar panels generate electricity in case of sufficient light exposure. Improper wiring can cause electric shock, overheating or fire. Inverter transforms the solar electricity into the electricity which can power household devices.
Installing solar electricity into the electrical system of your home is a specialized job. Wrong connections can result in the damage to your equipment and electrical faults. Never do electrical work that you’re not confident about, always use a qualified electrician. Do not undertake any live electrical work without the proper training.
Off-grid DIY solar system is something else. Such system stores the energy in batteries rather than transfers excess energy to the grid. Grid-connected system requires appropriate protection and consent from the network. Do not assume that your DIY kit automatically meets these requirements.
DIY Solar Installation Permits and UK Regulations
The installation of solar panels is possible in the UK without the presence of a professional. However they are subject to the building and electrical regulations. Many residential rooftop installations are exempt from any planning permission, although this is not the case for listed buildings and conservation areas.
Please consult your local planning authority prior to starting. There are different rules in England, Wales, Scotland and Northern Ireland. Grid connected solar installations typically need to be approved by the Distribution Network Operator. Smaller systems can be eligible for G98 notification after installation.
Large systems usually require G99 approval before grid connection. Please check the appropriate procedure with your network operator. Before buying equipment, read through the electrical certification and eligibility document for a Smart Export Guarantee. Some export tariffs require MCS certification or similar document
