Solar Panel Installation FAQs (Essex & London) – Your Questions Answered

Thinking about solar panels? Here are the most common questions AJK Energy gets from homeowners across Essex and London.

Do solar panels work in UK weather?

Yes. Solar panels generate electricity from daylight, not heat—so they work year-round, even on cloudy days.

How long does installation take?

Most residential installs are completed in 1–2 days, depending on system size and roof type.

Do I need planning permission?

Most homes don’t. Planning is usually only needed for listed buildings or some conservation areas.

Will solar panels damage my roof?

Not when installed properly. Professional mounting systems are designed to be weatherproof and protect the roof.

How much can I save?

Savings depend on system size and (most importantly) how you use electricity. The best results come when you use more power during the day, or add battery storage.

Can I add a battery later?

In many cases, yes. Battery retrofits are common and can significantly increase savings.

What’s the best next step?

Start with an assessment. A good installer will explain your options clearly and design a system around your home and usage.
