IMG 7015

Project Overview

Set within a picturesque rural setting, this property underwent a complete renewable energy upgrade to reduce carbon emissions, improve energy efficiency, and future-proof the home against rising energy costs. The project combined solar PV across dual roof aspects, a modern air source heat pump, and a battery storage system with inverter integration.

The installation was delivered collaboratively by:

A Greener Alternative – Heat pump installation
Greener Solar Solutions (by A Greener Alternative) – Solar PV, battery, and inverter installation.

The Solution

Solar PV System (Dual Aspect Design)

Solar panels were installed across both roof elevations, allowing:

  • Maximum energy generation throughout the day
  • Improved performance across varying sun positions
  • Balanced system output rather than reliance on a single orientation

This dual-aspect approach ensures consistent generation from morning through evening, enhancing overall system efficiency.

Battery Storage & Inverter System

A fully integrated battery and inverter system was installed to:

  • Store excess solar energy generated during the day
  • Provide usable electricity during evenings and peak tariff periods
  • Increase self-consumption and reduce grid reliance

The system intelligently manages energy flow, prioritising on-site usage and optimising efficiency.

Solar PV & Battery Storage with Air Source Heat Pump – East Sussex

unnamed 17

Project Overview:

This homeowner in East Sussex wanted to take a major step towards energy independence by reducing their reliance on both gas and the electricity grid.

With the long-term goal of creating a lower-carbon, lower-running-cost home, they chose to install solar PV and battery storage, allowing them to generate and store their own electricity for use throughout the day and into the evening.

To support the move away from gas completely, our parent company A Greener Alternative also installed an air source heat pump, helping the property transition to a modern, efficient heating system powered by electricity.

The Challenge: Reducing Gas Use and Grid Dependence

Like many households, this customer’s energy use was split across:

  • Gas for heating and hot water.
  • Electricity for household appliances and lighting.
  • Their goal was to bring everything under one cleaner, more efficient system, but without increasing electricity costs or becoming overly dependent on the grid.

Our Solution: Solar PV + Battery Storage

We designed and installed a solar PV system paired with battery storage, allowing the homeowner to make the most of the electricity generated on-site.

This setup means:

  • Solar power can be used in real time during the day.
  • Excess generation is stored in the battery rather than exported.
  • Stored energy can then be used in the evening and overnight.
  • Battery storage plays a huge role in reducing grid reliance, helping the customer maximise self-consumption and take control of when and how their electricity is used.

Supporting the Move Away from Gas

To complete the customer’s transition away from gas, A Greener Alternative installed an air source heat pump at the property.

Heat pumps are highly efficient and use electricity rather than gas and when paired with solar and battery storage, they become even more cost-effective.

This combination helps the homeowner:

  • Reduce fossil fuel use significantly.
  • Lower heating-related running costs.
  • Move towards a fully electric home powered largely by renewable energy.

The Background

This three-bedroom detached property in West Sussex was providing all heating and hot water requirements via a gas boiler. Looking to do their bit for the environment and with a plan to integrate a new system with Solar PV, the customer opted not to replace their gas system and instead explore the option of a more sustainable alternative in the form of an air source heat pump.

The Solution

A Greener Alternative have designed a system that utilises a single 6kW Midea R290 air source heat pump with a 170 litre hot water cylinder to provide heating to radiators and provision of all domestic hot water requirements. The unit is sited at the side of the property with services running back into the house.

The Midea R290 air source heat pump which is situated neatly at the side of the property extracts heat from the outside air to provide heating and hot water to the home.

The Result

The client now runs their entire heating and hot water system from a state-of-the-art air source heat pump that is not only a more sustainable solution but also means they will never pay a gas bill again! On top of this they will look to integrate a solar PV system that will supplement the running of the air source heat pump further saving them money.

This clean, modern solar PV installation on the pitched roof of a beautiful stone-built Surrey property is a great example of how to achieve solar generation without impacting the aesthetics of a property.

This type of installation is ideal for maximising solar energy generation on a residential property, especially when combined with battery storage. A great example of what A Greener Alternative have designed and installed and can also do for homeowners across Sussex, Surrey, Hampshire and Kent.

Ground Source Heat Pump

f 3

The Background

A Greener Alternative were appointed by the client to design a heating system at their rural property in West Sussex that would replace an ageing oil boiler and utilise a more sustainable heating system for both their house and garage annexe.

Through conversations with the client and understanding their vision it was decided that a ground source heat pump with geothermal boreholes would be the most suitable solution to meet the needs of the property.

The Solution

Two NIBE F1145-12kW ground source heat pumps were specified to take care of all the heating and hot water requirements for the house and a single NIBE F1245R-6kW ground source heat pump with built-in hot water cylinder for the annexe. The units are all sited in the large garage beneath the annex installed neatly at the back end to further utilise space.

With an adjacent paddock forming the ideal site for the heat pumps ground collectors a series of six geothermal boreholes were drilled vertically down each hole between 100-150 metres in depth. The boreholes are connected to a central manifold and services run back to the property using pre-insulated header pipe.

With the boreholes drilled, connected and services run back to the garage where the heat pumps are sited there is now very little evidence that the boreholes and groundworks have even taken place. Now the borehole work is complete there is no need to access them in the future and all service access is made via the manifold.

The Result

The three NIBE heat pumps reside in the garage as shown below with the taller unit supplying heating and hot water to the annexe and the two smaller heat pumps working in tandem to provide for the main house.

The NIBE F1255-6kW unit feeding the annexe includes a built-in buffer tank and hot water cylinder which provides all the annexe requires by way of heating and hot water.

The NIBE F1155-12kW units utilise the buffer vessel sited to the right of the heat pump units to reduce cycling of the heating system and to further improve efficiencies. The heat pumps and buffer supply the heat pump hot water cylinder which is sited within the main house to take care of all the hot water needs for the home.
