The Future

“The future depends on what you do today.”   Mahatma Gandhi
“The future belongs to those who believe in the beauty of their dreams.” Eleanor Roosevelt
“The future is a network of Zero Carbon Homes and Zero Carbon Workplaces, combining together in one big ‘virtual’ power plant.”
At Spirit, we are working together with our customers to realise our dream: a world where we live and work in low energy buildings, each with on-site generation of power, combining together to create a network of ‘micro’ power plants.

Energy Generation

  • Solar panels generate electricity.
  • On site battery storage balances on
    site generation and consumption, with
    excess electricity feeding into grid.
  • Electric vehicle charged by solar /
    battery, topped up by grid. Car battery
    may export to the grid in times of peak
    demand.
  • Low heating and hot water demand
    provided by air source heat pump.

Energy Demand Management

  • High specification insulation.
  • Low energy LED lighting to minimise
    electricity consumption.
  • Smart home monitoring & control to
    manage and reduce demand.
  • Every house is a decentralised power
    plant.
  • Power sharing: excess power is
    exported to the bi-directional grid
    when available.

Our Installations

  • Sparsholt & Andover College- 633kWp

    From September 2015 to February 2016 Spirit installed and commissioned Solar PV systems for 20 buildings spread out over Andover College, and Sparsholt College near Winchester. The arrays ranged from 32 to 400 panels on each roof. These all contributed to a total of over 2,500 BenQ 250W and BenQ 260W panels.

    It was the largest educational solar PV installation in the UK at the time of writing.

    The system was funded by GreenNation, so they have paid the full costs of installation. They benefit from the Feed-In tariff and Export tariff payments, and sell the electricity to Sparsholt and Andover College at a reduced rate. Sparsholt and Andover College benefit from the cheap electricity.

    The system was preaccredited so all systems could benefit from the higher 2015 Feed-In Tariff rate.


  • Mr D – Oct 2015

    Heat Pump: 5kW Mitsubishi Ecodan

    Cylinder: 180L Mitsubishi KS

    In October 2015, Spirit Solar Ltd installed a 5 kW air source heat pump for Mr D in Wallingford, Oxfordshire.
    The heat pump was designed to provide all of the space heating and hot water requirements of the property with lower running costs than conventional heating systems and no local exhaust fumes. If the electricity required to run the pump comes from a fuel-free renewable source (e.g. solar PV or wind power) then there will be zero running costs and zero CO2 emissions.

    It is estimated that Mr D will save £283 per year in bills compared with a gas boiler (even more compared to an electric heater), while receiving an income of £407 per year from the Domestic Renewable Heat Incentive.


  • Mr A- 6.4kWh

    In May 2016, Spirit commissioned a 6.4 kWh LG Chem lithium ion battery, with a Solax Hybrid inverter/charger to complement the 4 kWp of solar panels installed on the roof.

    With a battery, the annual usage supplied by solar to the property is expected to be around 78%, delivering greatly increased electricity savings.

    This was the first ever home battery system to be fully approved by SSE!

    We are proud to have been at the forefront in getting the DNO (distribution network operator – SSE) to adapt to a new way of thinking and approve the safety of our product before they are installed in homes across the UK . Unlike Solar PV there is no regulatory body to protect consumers, some companies haven’t even bothered to contact the grid – which could prove costly for the home-owner left with a product not fit for purpose.

    This represents a step towards de-centralised power in the form of micro generation and power storage will become the future for home owners at a time when grid independence is to become an advantage.
