Are Solar Panels & Battery Systems A Good Investment?

Solar Panels generate electricity from sunlight so they provide you with an ongoing source of energy. Most solar panels have a performance warranty of 25 years or more. 

Having a battery storage solution installed allows you to store the energy produced and choose when you use it. 

As energy costs continue to rise and in the future are likely to increase further a method of generating your own energy and storing it both have massive advantages. 

10 Reasons Why They Are A Good Investment

1. Reduce The Cost Of Your Energy Use

2. Reduce Your Carbon Footprint

3. Increase the Value Of Your Home

4. Get Paid For Generating Electricity You Don’t Use

5. Take Advantage of Zero Rate VAT on Solar Panels

6. Have Back Up Power In The Event of Power Cuts

7. Future proof Yourself Against Future Energy Cost Rises

8. Generate Free Fuel For An EV Car

9. Use Excess Electrical Power To Heat Your Water

10. Reduce The Cost of Running A Heat Pump


5 Reasons For battery storage

1. Store energy to use when its most economically beneficial to you.

2. Back Up Power in the event of power cuts

3. Increase the Efficiency of your solar system

4. You don’t need an existing solar panel system to start saving.

5. Increase your Return on Investment

Power Diverters & Water Heaters

As well as solar battery storage power diverters for water heaters can be useful additions to a solar system to increase efficiency. They work by diverting excess electrical power into a heating element that then heats your water tank. So you use less fuel, usually gas, to heat this water and the energy is free so you reduce your energy bills further. 

These products only work in certain circumstances and with certain systems so speak to us for further advice. We also consider whether you would get a larger benefit by just selling the excess power back to the grid via Smart Export Guarantee (SEG) scheme.

How can I get paid?

Your panels generate electricty, any excess that is not stored in a battery is fed back into the grid. You can get paid for feeding back in this amount. 

Originally the scheme was called the Feed In Tariff (FIT) but it has since been updated to the Smart Export Guarantee (SEG) Scheme. 

A popular Tariff for are provided by Octopus who offer a range of schemes with peak and off peak periods where you can be paid to export at rates up to £0.27p per KWh, please check for latest prices. 

You can choose options when you use an EV car to time charging that at a low rate and if you use a battery to make your system even more efficient.

We check the size, layout and orientation of your roof. If it is suitable we confirm its construction and strength are also suitable. If there are problems which prevent using the roof of your house you can always consider other roofs you have access to such as garages and outbuildings or a ground based array. 

The main factors which effect the panels performance are orientation of the roof, which direction is it facing, with south being the optimal and is there any shading which could effect use. If there is shading we can mitigate some of these effects using a different type of inverter.

Battery storage is simply using a battery as an energy storage device at one point in time so you can then use it at a later time when you wish to. This provides significant advantages in two main ways:

1. You can store energy generated by panels so you can use it later when either the panels are no longer generating or you have a hgher load than the panels are generating at the time you need it. 

2. You can work more efficently with tariffs that feature peak and off peak rates as you can time when you use the battery to avoid buying electricty during peak rate times and you can also time using it so you sell electricty at peak rate times. 

Both of these issues will make your system more efficient and provide a greater return on investment and more value for your home.

On average, our installations costs are between £500-1,000 lower than the MCS average price for solar installs in September 2023. The average cost of a solar panel and battery storage system in September 2023 was £10,380.

The cost of your installation will depend on various factors such as the number of panels you require and how big your storage solution is.  The number of solar panels, power of inverter and the capacity of battery we recommend will depend on your average energy usage and how many panels can be installed on your roof. 

With your solar panel system you will have warranties for the following:

  • Solar panels
  • Inverter
  • Battery
  • Workmanship 


Solar panels have two types of warranties a performance warranty which is usually between 20-30 years and a product warranty which is usually between 10-20 years. 

Inverters have a 5-10 year warranty period. You can buy a warranty extension from most manufacturers.

Batteries have 10-year warranties for 6-10,000 life cycles depending on the manufacturer. Your battery will still work when the warranty period ends, but, the battery capacity will be reduced.

Our insurance backed workmanship warranty is for a 2 year period.
