Did what it said on the box. Verified Purchase
My kit arrived with all the required components.The cable uses tinned copper conductors so it has additional corrosion resistance which is a bonus. I was fitting to an external garage that does not have mains power and the 4 light kit gives plenty of light. It is a bit fiddly to connect everything and you need to make sure that the wires are the right length as you only get the correct amount of ring connectors in the kit (i messed up and had to buy more). It is easily expandable and the solar panel is generating enough power to charge the battery on a cloudy day. Would recommend to anyone.

Excellent Verified Purchase
Fantastic, using them in my spare stables that do not have mains electric. Just enough to do late night stable duties, muck out & do rugs etc. maybe could do with supplying more cable, but i just went to local car shop and got some to finish the job. Great product, easy to install. Thanks.

Excellent Service Verified Purchase
I can't honestly review the product yet because I have not yet installed it. However, the service from The Solar Centre was top notch! A short time after ordering I was contacted, both by email and phone call that the cable was out of stock and it might take a couple of days to deliver the kit. This was Wednesday afternoon. The whole kit was delivered Friday morning! Excellent. Thank you. I will submit a better review of the kit later when installed

Good advice Verified Purchase
Was able to phone company and get honest advice about which battery to order. It all arrived on time but unfortunately without any cable. I phoned and a helpful lady apologised and said she would send the missing cable right away.

Brilliant kit, had it over a year now, you'd never know it wasn't mains power. Very bright too. Not difficult to install.

Great Kit Verified Purchase
I am really happy so far with this kit. I am using it to light my office at the bottom of the garden and so far so good. my office is 3m x 2.5m and the 4 bulbs provide easy enough light to read/ work by and the panel and controller seem to keep the battery well topped up. there weren't any instructions in the kit though, so i downloaded them from the sight (hence only 4 stars). Very happy so far. The kit has been installed for about a month so far.

The Geo 3 Verified Purchase
The Geo 3 - Mains Free Solar Lighting & Power KitIdeal for lighting internal space up to 48 square metres will light sheds up to 26'x20' (8m x 6m) the biggest problem i had upon installing this was the length of wiring was far to short my shed is 10 foot by 8 foot and i had to buy additional wiring to complete the installation the claim of lighting up the claimed 26 by 20 is farfetched also there wasn't enough wire clips.

Our Geo kits can be installed by anyone with basic DIY skills and are exempt from Part P of the building regulations which means there is no need to pay an electrician to have your kit installed and certified.

Frequently Asked Questions

Please can you tell me if it's possible to extend the cables between the pv cell and the battery without significant power losses, and how long the cable that is provided is? Many thanks
By Mary-Jane Tyrrell on Oct 22, 2021

Hello, it is yes, you already get 10m of cable, but there is a wiring kit to add more wire on. Please look up tsc wire and it will come up in the search bar.

Hi, would a standard 75ah leisure battery suit this kit as I have one already. Or would I need to order one from your site. Many thanks
By Josh lindley on Jul 26, 2020

This should be fine

The video shows the system being wired with a voltage controller, but this isn't shown in the kit. Is this needed? What would happen if we didn't have one? What are the benefits of using one? Which one would you recommend for use with the Geo 3?
By Sarah on Mar 28, 2019

The GEO 3 comes with a charge controller. You need a charge controller with this size of a panel as without one it would reduce the lifespan of the battery.
