What solar panels work involves
A domestic solar PV installation puts panels on your roof, an inverter somewhere sheltered such as a loft or garage, and connects the system into your consumer unit so the electricity you generate is used in the house first and exported when you do not need it. Most installs are completed in a day or two once the design and paperwork are agreed.
Solar PV costs depend on system size, roof type, scaffolding needs and whether battery storage is included.
Estimated cost
Most solar panels projects we hold cost data for fall between £6,000 and £9,500. 4-6kW system
The estimator for this service isn't available yet.
Estimated range only. The actual price depends on site-specific factors such as access, condition and specification.
What changes the price
- System size (kWp)
- The number of panels is the single biggest cost driver. A larger array costs more up front but the cost per kWp usually falls as the system grows.
- Roof suitability and pitch
- Orientation, pitch, shading and the condition of the covering all affect both the design and the labour. South-facing unshaded roofs need the least compromise.
- Roof type and fixings
- Slate, plain tile, pantile, metal and flat roofs all need different mounting kits and different amounts of time on the roof.
- Battery storage
- Adding a battery is usually the second largest line on the quote. It is priced by usable capacity and by whether the inverter is hybrid or AC-coupled.
- Scaffolding and access
- Scaffolding is normally required for anything above single storey. Awkward access, conservatories and rear-only elevations add to it.
- Electrical work and DNO
- Cable runs, consumer unit work, isolation and the grid connection application all form part of the job. Larger systems may need explicit DNO approval before commissioning rather than a simple notification.
Solar panels in Hastings
Hastings addresses in our coverage data start with the TN34 postcode.
It sits within East Sussex.

What a contractor will ask about your property
- Roughly how much electricity do you use, and when during the day?
- What is the roof covering, and how old is it?
- Is there shading from chimneys, trees or neighbouring buildings?
- Do you want battery storage now, or the ability to add it later?
- Is there space near the consumer unit for an inverter and isolators?
- Roughly what do you spend on electricity each month?
- Which way does your main roof face?
- Do you want battery storage included?
- What type of roof is it?
How a project usually runs
- 1
Survey and design
Roof measured, shading assessed, array and inverter specified.
- 2
Grid application
Connection notified to, or approved by, the network operator.
- 3
Scaffold and install
Scaffold erected, mounting and panels fitted, inverter and isolators wired in.
- 4
Commissioning and handover
System tested, certificates issued, monitoring set up, export registered.
Permissions and regulations
- Most domestic roof-mounted solar is permitted development, but listed buildings and conservation areas have extra restrictions.
- The grid connection must be notified to the network operator; larger systems can need approval before commissioning.
- The electrical work is notifiable and should be certified by a competent installer.
Problems that commonly come up
- Shading discovered on survey that reduces the workable array size.
- A roof covering near the end of its life, where re-roofing first is the sensible order of work.
- Not enough sheltered space for the inverter and battery.
- Loft insulation or cable routes that make the DC run longer than expected.
When you need a specialist
- Where the roof needs repair or replacement before panels go on, a roofer should be involved first.
- Where the supply is three-phase or the consumer unit is old, an electrician may need to make changes before commissioning.
- Where a larger battery or EV charger is planned, the whole load should be designed together.

Common questions
How many panels will fit on my roof?
It depends on the usable roof area, the panel size and any obstructions such as chimneys or roof windows. A survey measures the real area rather than estimating from a photograph.
Do I need a battery?
No. A battery increases how much of your own generation you use rather than export. Whether it is worth it depends on your usage pattern and tariff, which is why the estimate treats it as a separate option.
Will solar work on a north-facing roof?
It generates, but noticeably less than a south, east or west facing roof of the same size. A designer will normally use the better elevations first.
Is the estimate a quotation?
No. The estimator gives a range based on the answers you give. A quotation requires a survey of your roof, your electrics and your access.
