What Businesses Ask Before Choosing Eco Ess Solar Solutions
How much do commercial solar panel installations cost in London?
Most Eco-ESS installs come at no upfront cost thanks to our Power Purchase Agreement (PPA) model. This means your system is installed free of charge, and instead of paying grid prices at around 50p/kWh, you secure energy at just 11–18p/kWh. The result is immediate savings from day one, with the option to own the system long-term for a minimal daily fee — making solar adoption financially risk-free.
What guarantees and warranties come with solar panel systems?
All Eco-ESS solar panels and semi-solid state batteries come with full manufacturer warranties for peace of mind. In addition, Eco-ESS provides its own guarantee — if any part of your system fails, we handle the fix or replacement at no cost. That means your business is never left stranded and you can trust that your investment is secure and supported for the long term.
Will solar panels disrupt my day-to-day operations during installation?
No, Eco-ESS systems are designed with efficiency in mind. Using pre-wired isolators, modular panels, and streamlined installation processes, our accredited engineers keep site time to a minimum. Most businesses experience little to no operational downtime, meaning you can keep running your operations while your energy system is seamlessly put in place.
How does the Power Purchase Agreement (PPA) work?
With an Eco-ESS PPA, an investor funds, installs and maintains the solar system at your site, so there’s no capital expenditure. Your business simply buys the electricity it uses from the system at a contracted, reduced tariff compared with grid rates. Operations & maintenance are included for the life of the agreement.
Are solar panel systems reliable in the UK climate?
Yes. Eco-ESS solar and battery solutions are built and tested for UK weather conditions. We’ve successfully installed systems for industrial sites, schools, retail units, and councils across the country, proving their reliability in cloudy and variable climates. Combined with battery storage, businesses benefit from consistent, predictable energy supply even during low sunlight or grid instability.
Why should my business invest in solar panels?
Investing in solar with Eco-ESS reduces energy bills immediately, protects your operations with backup storage, and helps your business meet ESG and sustainability targets. With our free-install PPA model, you can transition to renewable energy without any capital risk, while proving to stakeholders, staff, and customers that your business is future-focused.
Do Eco-ESS install solar panels for businesses in London?
Yes — Eco-ESS actively delivers commercial solar panel installations in London and surrounding areas. Our network of accredited UK engineers ensures systems are installed to the highest standards, tailored to local regulations, and supported by regional expertise. No matter where your business is based, we can provide a full turnkey service.
How does Eco-ESS support businesses after installation?
Support doesn’t stop once your system is installed. Every Eco-ESS system includes real-time monitoring tools, access to UK-based engineer support, and a zero-failure guarantee where we repair or reinstall if anything goes wrong. That way, you know your system is always optimised and your investment continues delivering maximum returns.
Who owns the solar system after the PPA term ends?
At the end of the agreed term (typically 15–25 years, subject to contract), ownership can transfer to your business for a nominal amount. From then on you benefit from self-generated power with only routine maintenance costs.
