A homeowner near Manchester, England, got three quotes for the same solar-and-battery setup, and the spread in price was shocking. 

Here's what to know

In a Reddit post, a homeowner said three installers priced the same project at £13,315, £15,950, and £18,271. The post said the package included 17 AIKO 490W panels, two Sigen BAT10 batteries, a 10-kW inverter, along with bird mesh, scaffolding, and installation.

All three firms appeared to have strong Google and Trustpilot reviews, so the homeowner said the pricing gap was hard to make sense of.

"I'm honestly questioning where the extra £2.5K is going," they said.

"I'm obviously weary of going straight for the cheapest quote," they added, even though the company seemed legitimate.

For homeowners seeing gaps like that, it may be worth exploring EnergySage to compare home battery storage options and competitive installation estimates. EnergySage has teamed up with electrification brand Qmerit to help homeowners get the best price on home battery storage solutions.

Saving money on a battery install can make a major difference, as adding battery storage is one of the best ways to protect your home during outages, save money on peak energy rates, and gain more energy independence.

More background

One commenter said they had the same experience with inconsistent pricing and got better results by getting more estimates.

They wrote, "Got five more. Kicked all eight around the various suppliers to see if they'd fight each other on price. They did. Price came down a lot." They eventually settled on a Warrington installer on a roughly similar system for £12,000.

That same commenter described it as a major shift in the household budget, saying the household electricity now "cost zero to run." The household had two EVs, three kids, three floors, and an occasional hot tub, and it had previously cost about £400 per month to run. However, they said that they now "actually make about £40/month."

Equipment choices and tariffs can shape the value of a system beyond the sticker price.

Discussing that side of the equation, one commenter said Sig and Tesla are "the high end," and they use Octopus Go Loyal for 6.6p overnight charging while scheduling battery exports for between 5.30 p.m. and 7 p.m., when Agile prices rise.

A separate commenter from the Manchester area said buyers should also review installers on Companies House to gauge how long the businesses have existed, who owns them, and whether any warning signs appear.

The original poster said they had already been reviewing those records and had "seen some horror shows on there."

What can be done?

Several commenters suggested widening the bidding process before signing anything. The discussion also pointed to a mix of price-checking and due diligence. 

For homeowners startled by full-system quotes, Pila offers strong battery backup options, and the company's plug-and-play batteries are priced at a fraction of what a whole-home backup system would cost. Adding battery storage is one of the best ways to protect your home during outages, lower energy costs, and build more energy independence over time.
