Why Go Solar
The Numbers That Matter
Solar panels are one of the few home improvements that pay you back. Here's what a typical Milton Keynes installation looks like in practice.
Up to £1,200/year saved
A 4kWp system in Milton Keynes generates enough electricity to cut a typical household's annual import bill by £900–£1,200, depending on usage and time of consumption.
Smart Export Guarantee
With an MCS-certified system, you're paid for every unit of electricity you export to the grid. Most suppliers offer 7–15p/kWh. On a 4kW system, this could add £150–£300/year.
Protection against rising bills
Energy prices have increased over 60% in recent years. Every unit you generate is insulation against future price rises — your solar generation is essentially free electricity for 25+ years.
Added property value
Studies suggest solar panels add 4–14% to property values and improve EPC ratings — important as mortgage lenders increasingly factor energy performance into lending decisions.

Common Questions
Solar Panel FAQs
A typical 4kWp residential system in Milton Keynes costs between £6,500 and £8,500 installed, including all equipment and labour. 0% VAT currently applies to residential solar installations under UK policy. We provide fixed-price quotes with no hidden extras — what we quote is what you pay.
Based on Milton Keynes' average solar irradiance (~900 kWh per kWp per year), a 4kWp system generates approximately 3,600 kWh annually. At current electricity prices (around 25p/kWh), that's worth about £900 in saved import costs per year — more if you add battery storage to increase self-consumption.
On top of that, you receive income via the Smart Export Guarantee for every unit you export to the grid. Most suppliers pay 7–15p/kWh, adding a further £100–£300/year for a typical system.
Yes — modern solar panels generate electricity from daylight, not direct sunshine. They work on cloudy days, just at reduced output. Milton Keynes sits in the East Midlands which actually receives above-average solar irradiance for the UK. Germany, which has far less sunshine, is one of the world's largest solar markets.
In most cases, no. Standard residential solar panel installations in England fall under permitted development rights. Exceptions include listed buildings, properties in designated conservation areas, and some flats. We'll check this during your free survey and advise you accordingly — there are usually solutions even for restricted properties.
Solar generation is lower in winter due to shorter days and lower sun angles — typically 20–30% of summer output. However, energy prices are also highest in winter, so the savings per unit generated are at their peak. The annual generation figures we provide are averaged across all 12 months.
The Smart Export Guarantee (SEG) is the UK government scheme that requires larger energy suppliers to pay you for electricity you export to the grid. Rates vary by supplier — typically 7–15p/kWh. You need an MCS-certified installation and a smart meter to register. We handle the MCS documentation; you register directly with your energy supplier.
Customer Reviews
What Our Solar Customers Say
Had three quotes. Depth of Light came in fairly priced, but more importantly they were the only ones who walked me through the system design properly. That level of honesty won my trust.
Really professional service. They were on time, tidy, and explained how to monitor my system output. The MCS paperwork was sorted straight away. Would use again for the battery storage in future.
