Longi FAQs

Choosing your package, planning the installation and understanding what’s included.

How much does a Longi solar installation cost?

Our Longi packages start from £5,185, including installation and VAT. The price depends on the equipment, capacity and work needed at your property.

Compare the complete package rather than a single component’s retail price. Your free, no-obligation proposal sets out the equipment, installation work and total price before you decide.

Can I have Longi panels with battery storage?

Yes, we offer Longi solar and battery packages. The battery stores electricity for later use. The battery and inverter may be from a different manufacturer, so check each component in your proposal.

The right battery capacity depends on your electricity use and solar generation. We’ll discuss those together so you can compare a suitable package.

What affects the size of the system I need?

Your electricity use and when you use it are the starting point. For solar panels, roof space, direction and shading also matter. For batteries, we consider storage capacity and the opportunity to charge from solar or a suitable tariff.

We’ll discuss your home during the proposal call. A larger system is not automatically a better fit, and any savings will depend on your setup, tariff and energy use.

What warranty comes with my Longi package?

Your proposal confirms the warranty for each component. Panels, inverters and batteries can have different warranty periods and conditions, even when supplied in one package.

Keep your handover and warranty documents. Check the applicable registration, maintenance and operating requirements, and distinguish manufacturer product cover from installation workmanship cover.

Can I spread the cost?

0% APR is available over 12 months with a 25–50% deposit. Interest-bearing plans at 9.9% APR representative are available from 24 to 120 months, with a deposit from £250 up to 50%.

Finance is subject to status, affordability and terms. Your proposal shows the available plans, monthly repayments and total payable so you can compare them with paying in full.
