Solar & Battery Packages — Milton Keynes & Buckinghamshire
Save up to £1,800/year. Combined packages from £5,500 — 0% VAT, MCS & NAPIT certified, installed together for less.
Most homes that install solar panels export around 50% of the energy they generate — at just 7–8p/kWh. Adding a battery means you store that energy and use it in the evening when the grid costs 25–30p/kWh. That's a threefold return on every kWh you would have given away.
Fixed quote before any work begins. 0% VAT confirmed until March 2027.
The numbers are clear. Adding battery storage is the single most impactful upgrade you can make to a solar installation.

Savings calculated at 28p/kWh grid rate, 900 kWh/kWp annual yield (Milton Keynes), SEG at 7.5p/kWh. Individual results vary.
Solar and battery installed in a single visit. One set of scaffold costs, one day's disruption. Adding a battery later means a second installation and usually higher total cost.
A hybrid inverter handles both solar and battery in one integrated unit. No compatibility issues, better efficiency, and simpler monitoring via a single app.
The package price is always lower than buying solar and battery separately. Combined savings of £1,400–£1,800/year make the payback period comparable to solar alone.
Pre-wired for EV charger integration. When you switch to an electric car, your solar system charges it for free during the day. One joined-up energy setup for your whole home.
We assess your roof orientation, shading, consumption patterns, and meter setup to design the right system size. Takes about an hour — you get a full design proposal.
You receive a written quote with the exact system spec, all component makes and models, installation timeline, and projected savings. Fixed price — no surprises on the day.
Our team installs panels, hybrid inverter, and battery storage in a single day. MCS certificate issued, monitoring app set up, and your system is generating from day one.
Four package tiers to suit different homes and budgets. Not sure which is right for you? The solar calculator will size it based on your actual usage — or call us and we'll talk you through it.

Installing together is more cost-effective than adding a battery later — there's one set of scaffold costs, one installation day, and the hybrid inverter handles both in a single integrated unit. You also get a system designed and sized to work together from day one, rather than retrofitting components.
A 4kWp solar-only system saves around £900–£1,200/year. Adding a 9.5kWh battery increases this to £1,400–£1,600/year by capturing surplus solar that would otherwise be exported at 7–8p/kWh, and using it in the evening when grid electricity costs 25–30p/kWh. Typical payback is 8–11 years on the combined package.
Yes. Solar panels, battery storage, and hybrid inverters all qualify for 0% VAT when installed together on a residential property. This saves around £1,500–£3,000 compared to the standard 20% rate. The 0% rate is confirmed until at least March 2027, so acting now locks in the saving.
Yes. We can install a solar-compatible smart EV charger (such as a Myenergi Zappi) on the same day, wired directly to the hybrid system. This lets your car charge automatically on surplus solar or during overnight off-peak rate periods — reducing running costs as far as possible. Ask for an EV charger to be included in your quote.
We work with Fox ESS and SigEnergy — two of the most reliable battery brands available — paired with their own hybrid inverters for a fully integrated system. The right combination for your home is determined during the survey — we'll explain the options clearly before you commit to anything.
We also install Tesla Powerwall 3 — see our full Tesla Powerwall 3 UK pricing breakdown for installed costs and payback figures.
"Absolutely fantastic service from Depth Of Light! Mathew installed my EV charger perfectly, and the whole process was smoother than my morning coffee, and now my car charges like a dream. If you're looking for a top-notch installation with zero stress, this is the team to call. Highly recommend!"
"Called Depth of Light because I was having trouble with my electricity tripping when solar panels kicked in each morning. Matt came round within a few days and spoke with Solis. Between them the fault was identified and Matt came and fitted a new RCD. Problem solved. Fast, professional, friendly service. Would recommend."
"Matt did an amazing job! He was super clean, kept us informed every step of the way, and did a really professional job. We've used him for various other work since and we'll definitely keep using his services again and give him our highest recommendation."
