Installing solar panels is a big investment. One you’re going to want to protect.
Once your installation is complete, it’s important to make sure you receive all the proper paperwork to ensure that your system is legal, safe, covered by warranties and easy to maintain.
Not having the right paperwork could leave you exposed to issues down the road, so it’s useful to know what to expect upfront so that you know which questions to ask if anything is missing.
What does a typical solar installation include?
A standard home solar installation involves more components than you might realise. You’ve got the panels themselves, of course, but there’s also an inverter, which converts the electricity your panels generate into a usable form for your home. Many installations also include a generation meter, mounting hardware, DC and AC cabling, and various isolator switches and protection devices throughout the system.
If you’ve gone a step further, you may also have battery storage, an EV charger integrated into the system, or a diverter that sends surplus energy to your hot water cylinder.
Each of these components has its own specifications, warranty terms and expected lifespan. That’s why keeping hold of all your paperwork matters more than you might think. If something develops a fault five years down the line, you’ll want to know exactly what’s installed, who supplied it and what the warranty covers. Without that documentation, you could find yourself in a frustrating position when it comes to making a claim or getting a repair sorted.
DNO notification or approval (G98/G99)
Your DNO notification or approval documentation confirms that your local Distribution Network Operator (DNO) has been informed of or has approved your solar installation.
This is put in place to protect the grid, ensure your system operates safely, and maintain a stable and reliable supply of electricity to other households in your area.
If you ever choose to expand your system, install a battery or even add an EV charger, you’ll need to produce this documentation. It can also be required for insurance purposes, so keep it somewhere safe and accessible.
MCS or Flexi‑Orb certificate
The Microgeneration Certification Scheme (MCS) certificate proves your system meets official standards for safety and performance. Alternatively, the pricier but more rigorous Flexi-Orb certification may be provided for some installations.
Each is designed to ensure that your hardware is both safe and efficient to use, and is often necessary evidence if you are applying for any Government-backed incentives or if you’re seeking payment for electricity exported to the grid.
Electrical certificate (Part P)
An electrical certificate confirms that the electrical work meets UK safety standards to prevent fire and electric shocks.
For solar panels, Part P covers connection to your home’s wiring, inverter installation and any EV charger integration. It protects against future safety issues and can be essential in making insurance claims.
System schematic and component serial numbers
A system schematic shows how your solar panels, inverters, battery (if applicable), and wiring are connected. This will provide vital information if you choose to make any upgrades or changes with another installer.
Keeping records of serial numbers for components, including the panels themselves, inverters and batteries, can help with warranty claims, sourcing component replacements and troubleshooting. Again, this information can be extremely helpful to new installers.
Warranty documentation and registration
It’s important to keep hold of manufacturer and installer warranties for your panels, inverters and batteries. These show coverage periods, conditions, and registration proof.
If something goes wrong, your warranty may cover the cost of your repairs or replacement parts. Be sure to read through the documents after the installation, as some will require registration immediately after installation to be valid.
HIES/IBG cover
You may receive HIES (Home Insulation and Energy Systems) or IBG (Independent Buyer’s Guide) documentation. This confirms that the installer is insured and offers protection if there are any later issues or disputes with the installation. HIES provides a financial safety net for you in the event that your installer ceases trading for any reason, and also vets its installers to ensure they are working to an acceptable standard.
Operating manuals and monitoring app details
When operating manuals from various appliances start to stack up, it can be tempting to throw them away. Do not do this for your solar panels. It’s important that the paperwork for your panels and their associated parts is stored safely for the duration of the product’s life.
Manuals explain how to operate the inverter, battery, and other system components. They’ll be used by anyone cleaning or doing maintenance on the panels, as well as any future installers who may be working on upgrades to ensure that they work safely, without damage to themselves or the panels.
Monitoring apps allow you to track energy generation, consumption and battery use. Make sure you know your login details so that you maintain full control of your system.
Why collecting these documents matters
These documents are vital for ensuring compliance with legal and safety requirements. Having them to hand makes maintenance, warranty claims or future upgrades much easier. They also provide proof for insurance, property resale or grant/funding applications.
They represent a safety net and security for your investment and your financial future. Each can offer confidence that your solar system is reliable and well-documented.
At Electrical Innovations, we ensure that every installation is handed over with all necessary documentation and explained clearly to the homeowner. You’ll know exactly what each document is for and when you might need it in future. This gives you the peace of mind that your system is safely installed and protected with the correct paperwork.
