Choosing the Right Smart Energy Solution for Your Home or Business in North Cumbria

If you live or work in North Cumbria, you’ll know how changeable our weather and our power supply can be. From remote cabins and farms to busy family homes and offices, more people are looking at solar panels, battery storage and EV chargers to cut their bills and stay powered during outages.

This guide will help you understand your options, including Tesla Powerwall 3, solar PV and EV charging, so you can decide what’s right for your property.
 

 

1. Start Here: What Are You Trying to Solve?

Before you dive into products, it helps to be clear on your main goal:

  • “I want to cut my electricity bills.”
  • “I want backup power during storms and power cuts.”
  • “I’ve got (or I’m getting) an electric car and need easy charging.”
  • “The property is remote – I may need off-grid or part off-grid power.”
  • “I run a business and need predictable costs and reliable supply.”

Most people fit into one (or a mix) of these. Keep your top 1–2 goals in mind as you read.
 

 

2. How Solar Panels Can Help

Solar panels (solar PV) generate electricity from daylight and work well across the UK, even in the North. They produce the most when the sun is higher and days are longer, so you’ll see the biggest benefit from spring to autumn.

 

Is my roof suitable for solar panels?

Key things to check (we can assess this for you on a survey):

  • Roof direction - In the UK, south-facing roofs are ideal, with east- and west-facing also performing well. North-facing is usually less efficient and may not be recommended unless there are special circumstances
  • Shading - Trees, chimneys or nearby buildings can reduce output.
  • Roof strength and condition - The roof must be able to support the panels safely.
  • Available area - More panels = more potential generation.


If your roof isn’t suitable, there may be options like ground-mounted arrays on land, barns or outbuildings.


When solar panels alone might be enough

Solar panels on their own could suit you if:

  • You’re at home or on site during the day and can use most of the energy as it’s generated.
  • You’re happy to rely on the grid at night and during power cuts.
  • You want a lower upfront cost and are not ready for battery storage yet.

You can add battery storage or an EV charger later if your needs change.

 

 

3. What Battery Storage Can Do

home or business battery stores electricity for later use, either from your solar panels or from the grid at cheaper times
 

Key benefits of battery storage

  • Use more of your own solar energy instead of exporting it back to the grid for a low tariff.  
  • Protect yourself from power cuts – modern batteries can detect an outage and switch to back up in under a second, so your lights and key circuits stay on.  
  • Shift to cheaper electricity – charge the battery overnight on cheaper tariffs, then use that stored power during peak-rate periods. 
  • Reduce carbon footprint by making the most of renewable generation.


Why Tesla Powerwall 3?

Tesla Powerwall 3 is a high-capacity, all-in-one battery with an integrated inverter. It’s designed for homes and small businesses that want serious backup and bill savings.


Typical features include: 

Around 13.5 kWh usable capacity per unit – enough to cover an average home’s evening and overnight use in many cases.

  • High continuous power output (up to around 11 kW), so it can comfortably run multiple appliances at once.
  • Fast automatic switchover in a power cut, via the Tesla Gateway.
  • Indoor or outdoor installation with robust weather resistance, useful for exposed North Cumbrian locations.
  • 10-year warranty with at least 80% capacity guaranteed after 10 years.
  • Monitoring and control via the Tesla app, so you can see what you’re generating, storing and using in real time.

Multiple Powerwall 3 units can be installed together if you have larger loads or want longer backup.

 


4. Is Battery Storage Right for You?


Battery storage (with or without solar) may be a good fit if:

  • You experience regular power cuts and need certain circuits to stay on (heating controls, lighting, IT equipment, fridges/freezers, security, Wi-Fi).
  • You’re often out during the day and don’t use most of your solar as it’s generated.
  • You can access an off-peak or time-of-use tariff and want to buy cheap electricity overnight and use it later. 
  • You run a small business where downtime is expensive – workshops, offices, hospitality, remote sites.
  • You have or plan to have an EV, heat pump or other major electrical loads.

If your priority is mainly backup during rare power cuts and your usage is modest, we can model whether a smaller battery or different setup might be better value.

 


5. EV Charging: When Do You Need a Dedicated Charger?


If you own or are planning to buy an electric vehicle, a dedicated EV charge point is usually worth installing.

A dedicated EV charger typically offers:

  • Faster, safer charging than a standard 13A socket.
  • Smart features - scheduled charging in cheap-rate periods, monitoring of energy use.
  • Integration with solar and battery, so excess solar can top up your car where compatible.

EV charging is especially useful to combine with solar + Powerwall if:

  • You charge mostly at home.
  • You want to soak up midday solar rather than exporting it.
  • You’re on a smart tariff with cheap overnight rates.
 


6. Remote Cabins, Farms and Off-Grid / Part Off-Grid Solutions


In North Cumbria there are many properties where the grid is weak, unreliable or a long way from the building. For these situations, a tailored mix of:

  • Solar panels
  • Battery storage (e.g. Powerwall 3)
  • Possibly a backup generator

can provide reliable power with far fewer fuel deliveries.

You might need this kind of system if:

  • You have a remote holiday cabin, shepherd’s hut, off-grid Airbnb or bothy.
  • You’re running equipment in an outbuilding or farm building with poor grid access.
  • Upgrading or bringing in a new grid connection would be prohibitively expensive.

We can design systems that prioritise essential loads (lighting, pumps, freezers, communications) and use a generator only when absolutely necessary, keeping your running costs and noise down.

 


7. Quick Checklists 


A. Typical family home near Carlisle or in a village
 

You may benefit from:

  • Solar PV to reduce daytime grid use.
  • Battery storage (e.g. Tesla Powerwall 3) so you can use solar in the evenings and ride through power cuts.
  • EV charger if you have, or plan to have, an electric car.

Good if:

  • You want to cut bills, improve resilience and future-proof your home.
 

B. Business premises (offices, workshops, hospitality, retail)
 

You may benefit from:

  • Solar PV sized around your weekday daytime usage.
  • Battery storage to cover early morning / evening and provide backup.
  • Optionally, EV charging for staff or customer vehicles.

Good if:

  • You want more predictable energy costs and reduced downtime during local outages.
  • You have roof space or land suitable for panels.
 

C. Remote cabin, holiday let or farm building


You may benefit from:

  • Solar PV on the roof or ground-mounted.
  • High-capacity battery (Powerwall 3 or multiple units) for overnight and bad-weather cover.
  • Backup generator for extended poor-weather periods or peak loads.

Good if:

  • Grid access is limited, expensive or unreliable.
  • You want a quieter, cleaner alternative to running a generator all the time.
 

D. EV-first homeowner

You may benefit from:

  • Dedicated EV charger with smart controls.
  • Battery storage to soak up cheap overnight electricity or surplus solar.
  • Solar PV if you have suitable roof space.

Good if:

  • You do significant mileage and want to lock in cheaper charging and reduce reliance on public chargers.
 


8. How to Work Out What’s Right for You


Every property is different, but a typical assessment will look at:

  1. Your existing energy usage
    • Annual kWh from your bills
    • Typical daily pattern (day vs evening vs night)
  2. Your property
    • Type (home, business, farm, holiday let)
    • Roof direction, angle and shading
    • Space for equipment (garage, utility, plant room, external wall)
  3. Your priorities
    • Bill savings vs backup power vs sustainability
    • Budget and payback expectations
    • Future plans (EV, heat pump, extensions, extra outbuildings)


From there, SJD Electrical can model options such as:

  • Solar only
  • Solar + Powerwall 3
  • Powerwall 3 without solar (for off-peak charging)
  • Combined solar + battery + EV charging
  • Off-grid / hybrid systems with generators for remote sites

and show you estimated savings, backup coverage and payback periods based on realistic assumptions.
