Why invest capital in solar energy?

Choosing between purchasing solar PV outright or opting for a funded system just depends on your business’ long-term strategy and appetite for capital expenditure upfront. If your company has the financial resources to buy our solar panel solutions outright, you will benefit from the overall cost of ownership is lower. There are a number of other benefits to purchasing a solar PV system outright, including:

Make long-term savings on your energy bills

The future of the UK energy industry is uncertain. Estimates suggest that businesses using energy from the National Grid could see up to 10% compound annual price rises. With so much uncertainty over future energy costs, capital expenditure for solar helps businesses budget better for their overhead costs. Investing in solar allows a business to generate electricity on their own terms, doing away with expensive transmission charges on energy bills. Reducing your use of red-band energy can also reduce other network distribution charges like triad fees.

The National Grid has three half-hour settlement periods between November and February during which large businesses using energy at peak times are retrospectively charged with huge fees – often running into thousands of pounds. By installing a solar PV system, you can greatly reduce your DUoS (Distribution Use of System) charges and triad fees, making significant savings every year.

Earn money from your solar

In addition to saving money through solar power, your business could also earn money by selling solar-generated electricity back to the grid. If your business or public institution also owns a solar battery, you can charge it via the National Grid or through on-site electricity generation.

Through a competent operator, you can create revenue from the battery assets through various schemes. For example, Enhanced frequency response (EFR) is a scheme that allows a network of batteries to sell their stored electricity back to the Grid. This network will be set up and managed by an external operator and the money earned, often exceeding thousands of pounds, will be shared between the different battery providers. With your solar panels also acting as an income generator, solar energy becomes even more financially viable, as well as environmentally responsible.
