Green self storage units at Clear storage Hereford on a nice sunny day

Tender opportunity for the design, supply, installation and commissioning of solar PV, battery storage and EV charging point at our Rotherwas site in Hereford.


Clear Storage is a container storage, small business and caravan storage site in the heart of Hereford’s Rotherwas Industrial Estate. We are certified carbon neutral and are in the process of working towards making our business more sustainable leading to a complete move to renewable and natural energy sources.

Project Overview

We are looking to install solar panels and a battery storage system to power part of the storage facility and install an EV charging point. The installation of the solar panels will be on the roofs of a number of shipping containers that have been converted into self-storage units. An appropriate fixing system will be required for the panels to be fixed to the units without compromising the units.

Project Scope

The row of containers has sound flat roofs and are South, South/West facing. There are approximately 50 x 20x8x8ft containers in the row and they are located next to the electricity meter bringing power to the site. We are looking to install a 22.12 kWp solar PV retrofitted system capable of supporting the current daily usage of an element of the site with sufficient capability for peak time use and be scaleable for future growth. The battery storage requirement is to ensure that sufficient solar energy is stored to provide power up until 10pm at night and from 5am in the morning. The site currently averages ​25,822 kwh per annum.

We are also looking to instal an electric car charging point for customers with the ability to charge for usage.
