Battery Storage for PV

Home >> Technology >> Battery Storage for PV

As Tesla Powerpack certified specialists, we are the experts in solar battery storage systems for business. Using battery storage for solar PV, our clients can store solar energy to use during peak times, generate additional revenue & reduce their grid reliance.

What is commercial battery storage?

Solar batteries are large energy storage units typically found outside a building that charge up during sunny periods if linked up to a solar PV system, or during the night from the grid if there are low energy demands. The batteries’ Dynamic Firm Frequency Response (DFFR) will monitor and discharge the stored energy. The solar batteries themselves are made up of rechargeable lithium-ion, stored in smaller battery packs within the units.

EvoEnergy offers a full turnkey solution for solar battery storage that includes analysing your suitability and opportunities, specifying the right solutions and installation. We have strong relationships with some of the world’s biggest technology brands that help us to deliver industry-leading energy storage solutions and expertise to your business. Batteries can be installed as part of a wider energy strategy with commercial solar PV or as a stand-alone solution that creates an additional income stream by providing a dynamic response service to the grid. A solar battery is intended to be used for commercial energy storage and stores electricity for solar self-consumption, time of use load shifting, backup power, and off-the-grid use.

EvoEnergy and Tesla

EvoEnergy are proud to be an approved Commercial Battery Installer of Tesla Powerwall. Having a strong working relationship with Tesla has enabled EvoEnergy to install Tesla Powerwall packs throughout the UK, this commitment has ensured our clients that they will received high-quality installations and aftercare.

The benefits of installing commercial solar battery storage

A battery storage installation helps your business better manage its electricity consumption. By integrating with existing electrical connections, there are two main opportunities for businesses to see value from their batteries:

Store solar energy

Battery storage can hold energy from commercial solar PV systems, acting as a store for surplus electricity generated on-site rather than exporting it. In certain circumstances, a solar battery can be used to reduce the costs of upgrading the grid if the local infrastructure needs to be improved to facilitate the connection of new renewable systems, allowing you to control the energy that you use to power your site.

Generate additional revenue

You can also seek additional revenue from on-site battery storage, using it purely as an income generator. You can even use it solely for the benefit of your business’s operations, modulating your use of grid electricity to reduce costs. Alternatively, you may use a combination of the two – that’s the advantage of our batteries’ flexibility.

When connected to your site’s infrastructure, commercial battery storage will optimise the balance between generation and usage in a way that was not previously possible by protecting your business against future energy price rises, peak energy prices and business interruption through the following ways;

Storage of excess solar energy

Due to passing clouds and varying weather conditions on a typical day, solar electricity generation will fluctuate frequently during daylight hours. By incorporating solar battery storage, your business can create a controlled output and smooth generation profile by storing green energy above a certain generation (kW) in the battery. This energy can then be released back into your infrastructure at other times when the solar energy generation is not so high.

Load shifting

Your business can reduce energy costs by charging the battery when energy is cheap – either at night via the grid when tariffs are low and/or during the day with excess solar – and ‘shifting’ this power to periods when energy is expensive i.e. during the day and peak periods. Operating the battery this way will typically flatten out your company’s demand for energy from the grid.

Peak shaving

Transmission charges from electricity suppliers are an expensive element of your business’ energy bill, with few ways to reduce the costs. Off-setting your peak load demand with energy stored in the battery will flatten your demand at these peak points and ultimately create substantial savings on your energy bill. Reducing your peak consumption will also save money on distribution charges levied by electricity suppliers during these more expensive periods.

Reduced reliance on fossil fuels

When combined with solar PV, battery storage will help reduce your dependence on fossil fuels. Moving away from unsustainable methods of energy generation that are damaging our environment will shrink your carbon footprint.

External grid services

In addition to the above onsite services, there are ways that battery storage can utilise your company’s grid connection and provide an income to your business. The following services are generally provided through an aggregator. EvoEnergy can initiate an introduction to those with whom we have successfully worked:

Frequency response

This is onsite battery storage ability to quickly supply electricity to, or absorb electricity from, the grid at critical times. This might be in the event of a power station shutdown or the over-supply of electricity from wind during a weekend. Batteries are able to switch quickly to charge or discharge, making them ideal to meet frequency market requirements.

Capacity market (standby reserve)

Linked to frequency response, a standby reserve market exists and battery owners can bid into this annually to provide energy when called upon to do so by the National Grid. The challenge with income from these external grid services is there is no long term certainty over the price of these services, meaning that business owners need to assess the risks and market opportunities moving forward.

The National Grid is undergoing a period of significant change and whilst the grid is likely to always need balancing there is little certainty as to how this will be achieved into the future.

Is battery storage viable for my business?

The installation of a battery provides many benefits, though the ability to install a battery depends upon both your site’s infrastructure and the ability of the local electricity grid to accommodate it; EvoEnergy can make early enquiries on behalf of your business to ascertain the viability of a battery.

The value of a battery will also depend upon the use and charges that your business experiences and, if grid services are procured, on the value that an aggregator will pay for use of a battery.

We can give you indicative revenue streams, according to current market conditions and energy prices, and work with you to assess your opinions of where inflation will sit and how you value your network access.

Funding for battery storage

Currently, there has been a drop in battery technology, making them more affordable without reducing their functionality. There are many business owners who recognise the value and wish to purchase these benefits without the capital costs. Over the years, EvoEnergy has built up relationships with various battery funders who provide turnkey solutions for businesses prepared to enter into contracts for the provision of battery services.
