Clear answers for your solar journey.

Solar cells turn daylight into direct-current electricity. A solar inverter converts that electricity for use in your home, while any unused electricity can be stored in a compatible battery or exported to the grid.

Yes. Solar panels can generate from daylight, although output is usually lower than in strong direct sunshine. A good design considers annual generation rather than a single day’s weather.

Many homes can be suitable, but roof condition, usable area, orientation, shading, access and household electricity use all matter. Our online tool is a useful start; a survey confirms the final design.

You can use the online solar quote tool to explore your roof and indicative package choices, or speak to the HEG team. There is no obligation, and the final recommendation is confirmed through survey.

A south-facing roof can be favourable, but east- and west-facing roofs may also be suitable. HEG considers the roof faces, shading, usable area and how you use electricity before suggesting a layout.

Sometimes. The online tool lets you explore suitable roof faces, and the final layout is confirmed through survey. HEG does not include north-facing roof faces in its initial domestic design.

Nearby trees, chimneys and buildings can affect generation. We look at shading as part of the design process and explain how it changes the practical options for your property.

Many domestic installations can be permitted development, but restrictions can apply, for example for listed buildings, conservation areas or other local planning conditions. It is always sensible to check the position for your property.

Potentially, yes. Flat-roof designs need appropriate assessment of the roof construction, fixing or ballast method, layout, drainage and access. A survey is essential before a final recommendation is made.

AIKO all-black panels are selected for their clean roofline and their role in a modern HEG solar system. The final equipment choice is always set out in your proposal and confirmed for your property.

The number depends on usable roof area, roof features, safe edge margins, orientation, shading and the final survey. The online tool provides a useful initial estimate rather than a final layout.

The selected AIKO panels are supplied with their applicable manufacturer warranty and performance terms. Your proposal and handover documents confirm the exact product information for your installation.

They can provide a clean, modern appearance on many roofs, but the final design is based on the roof itself. We assess the layout, condition and practical installation requirements before confirming the system.

The hybrid inverter manages solar generation and, where selected, works with the Hanchu battery. It is an important part of how your panels, home use, storage and monitoring work together.

No. Solar can work without a battery. A battery is an optional way to keep more generated electricity available for later use, and the right choice depends on your household use, budget and goals.

HEG’s quote tool offers 5.12kWh, 9.4kWh and 16kWh starting options. The practical choice depends on your electricity use, solar design, available installation space and what you want the system to do.

Whole-home backup is an optional feature that needs compatible equipment, a suitable design and appropriate battery capacity. We explain whether it can be considered as part of a survey-led proposal.

Hanchu equipment selected through HEG is supplied with the applicable manufacturer terms. Hanchu ESS equipment is described with a 12-year manufacturer warranty in HEG product information; your proposal confirms the cover for the selected system.

A survey checks the roof, access, electrical arrangements, scaffolding needs, panel layout and product locations. It is how the online starting point becomes a design that is suitable for the actual property.

The programme depends on the agreed system and property. HEG explains the expected sequence for scaffolding, installation, electrical work, testing and handover before work begins.

MCS documentation records the installed system and is an important part of the handover. Your HEG handover pack brings the relevant installation and product documents together.

Grid-notification or application requirements depend on the system design and export arrangement. HEG explains the relevant process for your proposal; any third-party or DNO requirements are confirmed before installation.

HEG includes a five-year insurance-backed guarantee alongside the relevant installation documentation. The terms, cover and any product-specific manufacturer warranties are set out in your paperwork.

The Hanchu app and online monitoring help you view relevant solar generation, battery and system information. HEG also provides a customer portal for your key handover documents.

Solar systems have no moving parts, but you should follow the handover guidance, keep an eye on system monitoring and address obvious shading or debris where appropriate. HEG offers support and maintenance options if you need help.

They can generate throughout the year when there is daylight, although generation changes with the season and weather. Your system design and monitoring help you understand the pattern for your own home.

Start by checking the monitoring information and your handover guidance. If you need technical help, use the HEG support resources or submit a report through the Report an Issue page so the team has the right details.
