Energy and sustainability equipment finance

How do businesses finance solar, battery or EV charging installations?

Businesses installing solar panels, battery storage, EV charging or heat pumps typically use hire purchase or an asset-secured loan rather than a straightforward lease, because once fitted this equipment is closer to a fixed installation than a moveable machine, and lenders assess it against the business's ability to repay rather than treating the panels or battery as the main security. The up-front cost is large relative to a normal capital purchase, which is exactly why financing rather than paying cash is the norm in this category.

Buyers are businesses installing renewable or efficiency equipment for their own premises, and installers or energy service companies funding an installation on behalf of a client. The equipment, whether solar panels, battery storage, EV charge points or a heat pump, typically starts generating value from day one through lower energy bills or new charging revenue, but the initial outlay is considerably larger than a normal equipment purchase relative to the size of the business making it, which is why financing rather than paying cash upfront is the default approach.

Hire purchase or an asset-secured loan suits equipment that is fixed to the building and expected to run for its full design life, such as a rooftop solar array or a heat pump, because the business genuinely intends to own and keep using it rather than replace it on a technology cycle. For installations that are essentially inseparable from the building itself, an unsecured or property-secured business loan is often a more realistic structure than asset finance built around a machine that can be repossessed and moved.

Renewable and efficiency equipment is largely immoveable once installed, so lenders generally look past resale value entirely and assess the deal against the business itself, including its trading record, any long-term energy or grid contract attached to the installation, and its general ability to service the debt. This is a meaningful difference from a category like construction plant, where the machine itself is the main security. A business with a long-term power purchase or grid connection agreement in place is generally viewed more favourably as a result.

The mistake we see most often is assuming solar panels or a battery system are bankable security in the same way a tracked excavator would be, when in practice most installations in this category are financed principally against the business's covenant, not the physical equipment. Understanding this upfront avoids a business being surprised that its lending terms depend more on trading history than on the size or quality of the installation itself.
