Solar & Energy: 1 Company

What to check before going solar

A solar or home battery system is a long-term commitment that ties together equipment, installation, financing and sometimes your power supplier. Reviews in this category often focus on the gap between the sales pitch and the bills that follow.

• Own, finance or lease: buying outright, taking a loan and signing a lease or power purchase agreement all work differently. A lease or agreement can affect selling your home later.
• Savings estimates: ask what assumptions about energy prices, usage and sunshine are behind any projection.
• Incentives: government rebates and tax credits change over time and vary by location. Check eligibility with the official source, not only the salesperson.
• Installer credentials: check licensing and any certification required where you live, and who carries out the installation.
• Warranties: panels, inverters, batteries and the installation work often have separate warranties. Ask who honors each one if the installer closes.
• Grid connection: find out who handles approval from your utility and how long it takes.

Common problems and how to avoid them

Door-to-door and phone sales with same-day deadlines, delays in switching systems on, and roof leaks after installation are frequent complaints. Get at least two written quotes, read the full finance agreement, and make sure the roof is in good condition before panels go on.

A long warranty depends on the company still trading, so check the domain age on an installer's CandorRated page along with who appears to run the site and the contact details we found. The location filters on this page show installers serving your region.

Frequently asked questions

Will solar panels remove my electricity bill?

Not always. Savings depend on your usage, system size, local tariffs and how exported power is credited.

What happens to a solar lease if I sell my house?

The lease usually has to be transferred to the buyer or paid off. Read the transfer terms before signing.
