Step 01
Tell us about the property
Start with a few practical details about your home and roof.
A helpful place to start
Three useful places to begin.
Read the short practical points first, then use the detail, independent resources and HEG routes that match your question.
02
Your system
Understand how AIKO panels, a Hanchu inverter, optional storage and monitoring can work together.
03
Your installation
See why a survey, clear scope, paperwork and handover matter as much as the products themselves.
See it in context
A solar system is more than a roof full of panels.
A well-planned design brings generation, home use, monitoring, optional battery storage and practical installation details together. Your survey turns the broad guide into a proposal for your own property.
1
Explore the starting point
Use our online quote tool for a property-led first look, then keep the result as an indicative guide.
2
Ask the practical questions
Use the linked guides to understand roof design, equipment, mounting and the documents that matter.
3
Confirm through survey
A survey confirms roof condition, access, electrical arrangements, equipment placement and final system design.

Questions people often ask first.
Open the answers you need. Where the answer depends on your home or chosen equipment, we explain what a survey or proposal will confirm.
Where should I start if I am new to solar?
Start with the roof and your household electricity use. The online quote tool is a useful first step, while the Solar FAQs and guides help you understand the choices before a survey confirms anything.
Do I need to understand every product before asking for a quote?
No. It is helpful to know what matters to you, such as a clean roofline, battery storage or monitoring, but HEG explains the panel, inverter and battery options in plain English.
Can I explore solar and battery storage together?
Yes. The quote tool lets you explore solar-only and solar-and-storage starting options. A survey and conversation confirm whether the proposed equipment is practical for the property.
What happens after an online quote?
If you want to continue, HEG talks through the starting design and arranges a survey. Roof condition, access, electrical work, scaffolding and the final layout are then confirmed before installation.
Can I export unused electricity?
Potentially. Export arrangements and eligibility depend on the installed system and tariff. Ofgem’s Smart Export Guarantee guidance is a useful independent starting point.

Short product overviews to help you understand compatible solar and battery features before you request a tailored HEG proposal.
Battery safety overview
Hanchu ESS battery safety features
See the safety features presented for a Hanchu ESS home battery, including BMS monitoring, fire-safety detection and the internal protection measures shown in this overview.
Smarter charging settings
Weather Optimise in the Hanchu ESS app
See how compatible systems can use a chosen charge window and weather-condition-specific state-of-charge targets. Settings and outcomes depend on the system, tariff and weather forecast.
Solar generation feature
Hanchu ESS Shadow Scan
Watch how Hanchu ESS shadow management scans the PV voltage range to help identify the best available operating point when partial shading creates multiple power points.
Works with Octopus
A Hanchu hybrid solar-and-storage design can be planned around compatible Octopus time-of-use tariffs. Octopus confirms current tariff availability and enrolment.
Ongoing care is optional
